Karen is absolutely amazing!! We are lucky to have found her as our realtor. My husband and I got the perfect home as first-time home buyers, and we still can't believe how smooth the process has been! We appreciate so much how knowledgeable Karen is about the market, how thorough she is in helping us prepare our offer, how responsive she is in addressing our questions, and how kind and thoughtful she is as a person. She is truly there every step of the way, and we are very grateful.

Karen was wonderful to work with. She is knowledgeable and very thorough. Very calm and reassuring which is so helpful in the hectic stressful process of buying a house. She id very quick to respond snd made sure we had answers to every question or concern. Loved how she was never pushy and was always very honest. Loved working with her and now think of her as a friend.

Karen is amazing, really knows how to get things done even in this incredibly fast-moving and competitive market. We were woefully unprepared and had no idea what we were doing when we started, but she guided us through all the way.

Karen was great! She helped us sell our house in Sharon, MA. A few days after meeting with her, we were all set to go on the market. She helped us find painters, and other professionals to get our house in tip-top shape to sell. We had multiple offers after the first weekend and sold our house quickly. Karen had great ideas and suggestions, plus her wealth of experience was invaluable in helping us find the resources needed to close the deal. We highly recommend Karen.

Karen helped my wife and I buy a new home in the Brookline/Newton area, and she was amazing from start to finish. My wife and I were first-time buyers and relatively clueless after being long-time city apartment renters, but Karen helped us navigate the whole process. Karen was great at identifying different homes to help us figure out what we really wanted, gave us great pointers in what to look for in listings, neighborhoods, and open houses, and was a total pro at creating a competitive offer that got us what we prioritized.

With her help, we were able to find a great home, and she has checked in on us a few times well after closing. She really cares for her clients, and we felt she was always available, working 24/7 on our behalf.

I would give Karen Tanzer 10 stars if I could! Karen helped me buy & sell a house in 2023. She is knowledgable, professional, always calm & goes the extra mile (and more!) to help her client. Her advice was excellent, from recommending a thorough inspector to getting my house in perfect order before putting it on the market. She went above & beyond in many ways. I admire her integrity & her adherence to the rules regulating realtors. I recommend her without reservation.

Karen is an outstanding realtor! She is knowledgeable, thorough, and detail-oriented. She made my husband and I feel like we were her only clients. She was always available by phone and frequently messaging us about another detail or strategy to think through, which was greatly appreciated. We had run into some issues with getting financing prior to working with Karen because my husband and I had both recently become self-employed. Karen directed us to a bank that gave us a mortgage with an extremely competitive interest rate. With Karen's assistance we purchased our beautiful single family home below asking price, got it inspected, and negotiated for several repairs to be done before we moved in. Karen also connected us to another client, who sold us high-quality furniture at a discounted price. Karen helped us every step of the way with kindness and professionalism. I can't recommend Karen highly enough!

Downsizing was not easy for us. We were nervous, uncertain and not quite ready for the challenge. Karen Tanzer understood our situation and with patience, experience and insight, she guided us through the process. In fact, I think she knew what we needed and wanted before we did!
We explored many options and ultimately found the perfect condominium. We are thrilled and we owe it all to Karen. We recommend her unequivocally.

I first used the services of Karen six years ago when I sold my single family home and purchased a condominium. Karen assisted me in both transactions. When I recently decided to sell my condominium, I did not consider anyone besides Karen to be my agent. From our first meeting to discuss the sale of my condominium (timing, pricing, marketing strategy) through the closing, I could not have been more satisfied. Karen is professional, knowledgable, very well orgaized and works well with all parties involved in the transaction. The advice I received from Karen was spot on and made the sale/closing process stress-free and efficient. I highly recommend Karen to anyone looking for a top-notch real estate agent to buy or sell a property.

Karen is "the best" realtor you can get in the area. Right from the first call we felt a huge difference in the level of service and care she provided. She found wonderful properties and tried to find a home that would match our criteria. We were new to the area as we moved from out of state and wanted someone who we could trust. The home that we finally went for was a new construction which she helped us negotiate to change the plan to match our needs. She convinced us to take a look when we were reluctant and we are glad she did because she knew it would meet our requirements.

After we signed the contract, she was proactive in helping us with the builder. She was always available on our calls with the builder and an active listener, taking notes and having follow up calls with us to point out something if it was missed.

She was gracious enough to regularly visit the property for us and make detailed videos to show us the progress and we never had to ask if she could go and check it, she would just do it. It is extremely hard to get a new home constructed while not being in town, but with Karen on our side we never felt we needed to come in and check regularly because she was our strongest advocate with our best interests in mind. In summary, if you have Karen as your realtor, you can guarantee she will go above and beyond for you.

My wife and I purchased a home from Karen in 2015 and were so impressed by her professionalism and knowledge that we chose to use her as our listing agent when our family began to outgrow our home in 2020. Our plan to sell was knocked off track by the pandemic and a myriad of other factors, but Karen was understanding, gave sound advice, and was ready to help us when the time was right.

There was no facet of selling our home that Karen was not able to respond to quickly with an informed opinion or solution to. She helped us choose when to put our house on the market, get our house ready to sell, and negotiate a great price. Karen is also very personable while staying professional. You may end up spending a LOT of time with your realtor depending on your situation and you want someone like Karen who is not dull or boring, but brings an enthusiasm, interest and positivity to her work that will ensure you that she is committed to doing what she does well.

When it came to buying we really hit a home run. A beautiful home had a substantial price drop that put it near the top of our range. We were able to visit the home and get an offer accepted on it a few days after the price drop and right before an open house that would have driven the cost of the home way up. We are still in a little bit of disbelief over how blessed we are to be in our current home! Karen's advice in that situation as well as the fact that she worked really well with the seller's agent gave us confidence that our offer was a good one. We were ecstatic when it was accepted!

Suffice it to say we bought from, sold with, and bought homes with Karen and we will not hesitate to call her for our next real estate transaction no matter what it is.

Karen is a superstar agent! In the height of the pandemic real estate market, she helped us beat out several offers for a condo that we loved. After a change in circumstances, she helped us sell that same condo 1.5 years later for significantly over what we purchased it for. She is incredibly knowledgable and goes above and beyond for her clients. Buying or selling a home is a naturally stressful process, but Karen makes it as easy as possible. Can't recommend her enough!

Karen was the ultimate resource for my fiancé and I on our first time home buying journey. She was knowledgeable, professional, punctual, and wise with her years of experience both in her role as an agent but also as a guide to the areas we wanted to buy in. We struggled a bit with the fast-pace market during 2020-2022, but she had the tenacity and patience to help us find the perfect first home for us. I would recommend her whole-heartedly to any and all in the market today.

We really can't say enough about Karen! Our family of four (including two small children) had a very tight window to move from Kentucky to the Boston area for work. Karen helped us every step of the way by creating a "plan of attack" to view properties and acclimate us to the Boston market. We appreciated her honesty and expertise in helping us to navigate what options would be best for our family. Because we didn't want to purchase a home sight unseen Karen was willing to clear out an entire weekend just for us to visit. She was so kind to our two boys (ages 5 and 3) as she helped us to see nearly a dozen houses and ultimately land our current home!

Our boys still ask about "Miss Karen" as they enjoyed our time with her so much. Even post-move, she has been so helpful connecting us with resources in the local area; which is extremely helpful as a transplant. We plan on staying put for a good while, but if we ever do decide to move, Karen is the first person our family would call!

Searching for a house in this market and this part of the country is a notoriously difficult endeavor. When we started looking we didn’t know as much about the process and were feeling quite overwhelmed. Karen was great at reassuring us and patiently teaching us a few of the tools and tricks to both make the process easier on us and feel competitive in tough market. The process of finding a house was not easy, we still have to do our own due diligence, and Karen was forward with us about this. She put us in contact with other people when necessary, in order to get the answers we needed in a timely fashion. She was always professional, persistent and proactive, just a few of the many qualities that a great realtor requires to get the best house for their clients. We finally found the house of our dreams and are extremely happy. Karen was with us also during the closing process and we will always feel grateful for her guidance and expertise and hope she can help others along this difficult yet ultimately rewarding journey.

Thanks Karen, we hope to have you over for a BBQ soon!

She was very informative when we were viewing the house, pointing out all the details that could matter for us. We learned a lot how we should look at a home and could finally find our first home.
Not only was she professionally great, but we also felt that she really cared for us. We could truly rely on her advice. We were very lucky to have her with us.

Karen was fantastic to work with. Prior to listing the house, she did a great job of offering suggestions on things we could do to make the house more marketable, but at the same time not being too pushy and leaving the ultimate decision up to us. When fielding offers, it can get complicated with the number of different combinations of contingencies and she did a great job of laying it all out for us to understand. She provided her insights and advice when needed, but again allowed us to feel empowered to make the final decisions. It was an older house we were selling, so lots of problems came up along the way (septic, smoke detectors, building codes, etc) but each time Karen was one step ahead and had a list of contractors ready to provide quotes from people she works closely with that would gave our items priority in order to meet strict deadlines. She went above and beyond in this regard, meeting many of these contractors at the house when I was unable to be there. We ended up closing on time with an offer well over asking thanks to Karen. I would highly recommend Karen to anybody buying or selling a house in the area.

It has been a pleasure working with Karen Tanzer. I recently relocated from San Diego to Massachusetts and needed a professional Realtor who would be able to be my eyes & ears as I was out of state. Karen was very responsive; detail orientated and went above & beyond what was needed during the buying process. Karen would schedule showings ahead of my visits, as well as have a Zoom call during a snowstorm so that could view a home that I would eventually be the proud owner of. I would highly recommend Karen for any future real estate need; whether buying or selling. Thank you, Karen!!

My wife and I have used Karen Tanzer THREE times at this point after just recently using her to purchase our forever home. She has experience in all aspects of Real Estate. For example, our family used a VA backed loan and Karen knew everything there was to know about them which is rare because most agents don’t have this knowledge. Karen helped us purchase a Condominium the first time we used her and the process was flawless. She helped us find the right Condo and we couldn’t have been happier. When we needed more space for our growing family she again found us a cute two bedroom home and helped negotiate an unreal offer. Finally, after living in the 2 bedroom home our family grew once again and we needed another upgrade and Karen helped us on this as well. It should be highlighted that our last two offers were contingent on the sale of our homes and Karen was able to get them accepted which is tough to do in a competitive market.

Karen is someone you can trust and is genuinely a kind person which is important to us and should be to you too. A lot of agents give the feeling they are in it for themselves, but Karen truly cares about YOU. She makes you feel like you are her only client. At this point after three totally different purchases Karen showed us her expertise is wide ranging and there is no home or condo too little or too big for her to handle. Out of all of these sales and purchases and times interacting with Karen she now feels like Family. Choosing Karen to be your agent would be the best decision you make while making the biggest decision of your life.

Karen helped us purchase our first home and she has been excellent throughout the process. She was available to answer any questions during the process and continue to be available long after the closure.

We have been looking to purchase a house in the crazy 2021 market for a few months with another fairly new agent before we found Karen, we immediately realized how much value a seasoned agent can bring in. We closed on the first house we saw with Karen!!

Karen has been helpful in dealing with all aspects of the house and it has been a pleasure working with her. Highly recommend Karen for anyone looking to buy a house.

We have been very fortunate not once but twice to work with Karen as our realtor. Karen helped us buy our first home in 2015. Her due diligence and years of experience in the field helped us find the home of our choice - that definitely fit our comfort and price range. She was very transparent, informative and also kept us apprised on all the minute details, delays and was on top of all the follow ups. In short our transition from renters to first time homeowners was smooth and a happy transition.
Now five years later when we decide to sell the house, Karen helped us sell the house without any issues especially in the pandemic phase when housing markets were very dicey.

We would highly recommend Karen to help you buy or sell your house.

Karen is an A++ Real Estate Agent. Karen has been our go-to real estate professional since 2013, and has guided us through buying and selling three homes! Most recently, Karen assisted us in selling our home in the suburbs of Boston as we were relocating out of state. For this transaction, Karen did a fantastic job of representing our home. We wanted to take advantage of the hot sellers market, and Karen did not disappoint. within a weekend, Karen procured us an offer that was well over our asking price, with no contingencies or inspection. We were able to move straight to our purchase and sale agreement, and the entire transaction went through very smoothly.

Previously, Karen did an exceptional job guiding us through selling our Boston Condo and moving into our suburban home. On the buying side, Karen's negotiation skills saved us $25,000 off the list price of our new home with a seller who initially was not willing to negotiate at all. From there, Karen helped us navigate the rest of the purchasing process smoothly and efficiently.

On the selling side, Karen was able to get us 8 offers in a single weekend, all over asking price. Unfortunately, our first buyer backed out after the home inspection, but Karen immediately went back to work. Within 24 hours of losing our first buyer, we had a signed offer with one of the other interested parties (for practically the same sale price), and the rest of the sale transaction was smooth sailing. Karen turned a difficult and stressful situation into a non-issue, and we ultimately sold our home for 15% over our asking price!

Karen is dependable, knowledgable, trustworthy, and kind. We consider ourselves very lucky to have had her on our side for all of our real estate transactions.

We feel very lucky to have worked with Karen, an experienced, hard-working, and thoughtful realtor.

This was our second time working with her; this time to sell our home. We started our conversations with Karen early and we discussed an ideal timeline for preparing our home for listing. Karen was watchful of the market and encouraged us to list sooner rather than later. Per her advice, we listed our place on a Friday, held one open house on Sunday, and accepted an offer right away!

Karen does an exceptional job answering and anticipating questions, explaining all processes, and expectations. She is detail-oriented and forward thinking. She really devotes her time to her clients, and we always felt like we were her top priority. Furthermore, we really appreciated her ability to connect us with outside resources (e.g. staging expert, cleaning services, marketing experts, legal).

Having worked with Karen to both buy and sell, we can say with confidence that anyone would be lucky to have her as their realtor.

Karen Tanzer brilliantly guided us through the difficult task of finding a condo for my mom. From our very first meeting with her, she actively listened to our needs and asked us the right questions to help us discover what was really important to us. She was extremely communicative throughout the several months that we spent looking for properties, sending us listings that matched our needs and making herself available for showings with very little notice. She knew all the "inside tips" that only someone with her experience and level of connections in the area would know. Without her and her expertise, I am certain that we would have lost out on the property that we ultimately purchased, which was subject to multiple offers. Having previously purchased another property with a different agent, I can say for certain that Karen is at the top of her field and I would not hesitate to recommend her and hope to work with her again.

Karen was an incredible agent for my wife and I to work with. Something that separated her from other real estate agents we’d previously worked with, was her priority on finding the right home for us, rather than just making a sale.

I would definitely recommend Karen as an agent and would use her again in our next purchase.

Her knowledge of real estate is encyclopedic and we were constantly impressed by how much she could tell about a house by picking up on subtle details that we never would have thought to look for. She knows the Sharon market exceptionally well.

She was professional, accessible, responsive, usually within second to minutes, to all of our questions, and took the time to get to know us and develop a nuanced understanding of the kind of home we were looking for. Additionally, as first time home buyers, we had lots to learn and she took the time to educate us and make sure we had a good understand of the process.

My husband and I recently sold our condo and purchased a single-family home. When we made the decision to sell our condo (had a baby) we decided to use Karen Tanzer who is quite literally the best in the business. Karen helped us purchase our condo five years ago. When we bought our condo Karen made the process smooth, simple, and honestly almost fun. She made my husband and I feel as though we were two of her good friends. Karen was always available when we had questions and made us feel like we were her only clients. Watching Karen sift through various properties was pretty amazing. She gave us essentially scouting reports on each one. She gave the pros and cons and her own personal insight into each property until we made right decision. With that being said, when the time came to buy a new home we went straight to Karen Tanzer. We are now in our new home and couldn’t be happier.

If you are new to real estate or simply not happy with the real estate agent you currently have Karen Tanzer should be number one on your list. In addition, if you are a veteran or VA eligible Karen understands the VA guidelines like no other.

In sum, buying and selling property can be very stressful and at times overwhelming. Karen Tanzer and her many years of experience not only alleviate the stress, but as I’ve said above she actually makes it enjoyable. After all the home buying experience should be enjoyable because buying a home is one of the biggest decisions if not THE biggest decision someone hast to make in life. So if you are looking for someone who is meticulous, organized, hard-working and above all caring then you should go no further than Karen Tanzer.

Karen is amazing! We had listed with her 12 years prior to my recent sale, and due to unforeseen circumstances, we had to take it off the market. She left such a lasting impression, when I was ready to sell again--12 years later--I knew I would call Karen. And I did!

Professional, thorough, diligent...she does not miss a detail or a timeline. Her knowledge of the area and market experience makes her invaluable to anyone relocating locally or otherwise. As we walked through the listing agreement, comps, negotiations, or whatever element of the process, she always brought multiple perspectives while respecting my opinions or questions. She kept me on track and informed at every step including supportive calls/texts for tasks on my moving to-do list! What a help!

She has a great network in the area as well as with Coldwell, going the extra mile to set me up with a relocation agent on the other side of the country. Even after my deal was done, she called me to make sure I was receiving timely and experienced service on the other end! That connection made a seamless transition to our new town--a lifeline.
Thanks Karen and thanks Coldwell!

Besides her great experience and professionalism, Karen brings a calm, steadiness and good-humor to what can be an emotional and chaotic time for any family. She is the only choice for an agent.

If you are looking for a real-estate agent, look no further. Karen is simply the best in business and we have experience with agents across multiple states and two continents. You will make a huge mistake if you choose to go with another agent, especially in Sharon and neighboring communities.

We are relative newcomers to Massachusetts, having been here for four years and started looking to buy a house around Newton. As we had to expand our search we finally settled on Sharon. However, we were not happy with the first two agents we worked with, so we asked a local restaurant owner for a recommendation for a local agent. We were beyond lucky to have her give us Karen’s name. Karen helped us through two failed offers including one that we had to rescind after the inspection report and another where we could not agree on the price with the seller. Ultimately, she supported us through a long and complicated process to purchase our dream home which she found for us.

First of all Karen is extremely knowledgeable about the market and quickly spots and points out any potential issues with a property. She is not pushy nor does she try to generate the hype that is so common around Boston. With Karen there is simply none of the silly talk about micro-location, “coming in strong with over-the-asking offer”, bidding wars that are likely to happen, and being “embarrassed to send that offer”. She does not pressure the buyer nor does she tug at the heartstrings trying to close the deal. She is very patient, level-headed and, most importantly, correct when it matters. Properties she described as overpriced truly sat on the market for a long while and others that she said might be under-priced truly moved immediately. This has not been our experience with other agents who tended to describe every property as slightly under-priced and urged quick offers, considerably higher counter-offers, etc. She was very good at engaging us on our level, meaning explaining the basics when appropriate but engaging us at a much higher level on issues that we understood better, which is unlike many agents we worked with. We have experience with real estate in other countries and can spot some of the serious issues. Karen never underplayed those and when she disagreed, she was mostly correct. We also understand financials better than most, one of us being a PhD Economist, and Karen never tried to convince us of some nonsense regarding loan terms, market conditions, etc, like some other agents did. There was no pretense to her approach, nor the “expert posing” where some agents present very basics as some “high secrets of real estate transactions.” Also, it was a true exception that she would send someone else to show us houses that were “inconvenient” for her to show, which is one of the reasons we were looking for a different agent before we found her.

Most important of all, Karen was extremely patient through our VERY complicated transaction involving a short sale. She kept in constant contact through 4-month long process from offer acceptance to closing, making sure to check in and move forward the lender that had to approve the short sale. She was available to talk after hours and on weekends and was, in general, a true pleasure to work with.

Bottom line, you will make a huge mistake if you do not choose Karen as your agent, especially if you are looking to buy in Sharon and neighboring communities.

Karen helped us find and purchase the right house for us. She was thoughtful, persistent, and helped us over some hurdles. She covered a large area including Sharon, Foxboro, Walpole, Easton and Franklin. I highly recommend her.

We are so grateful that Karen Tanzer was our realtor for our recent home sale. We had intended to interview three agents, but she was so well prepared and insightful, we chose her and skipped making other appointments. We had a busy summer booked with two sets of house guests and a three-week vacation, and she expertly coached us on de-cluttering and the improvements that would pay off in a higher sale price based on her extensive local knowledge. We knew our preferred timetable would be tight and it was, but we made it. Thanks to her suggestions for service providers and solutions, and being able to call on others who had helped us before, we managed to get a lot done in a tight timeframe.

Karen’s communication skills were showcased from her pitch perfect timing to drop by and encourage our efforts, help us keep on top of deadlines and agreements, and responsiveness to our questions. Her process expertise was invaluable when our first buyer dropped out without giving a reason and she got us set up for another open house right away. Her negotiation skills were showcased as she helped us weigh the pros and cons of two sets of multiple offers and work though counter offers.

We are delighted with the outcome - buyers who really appreciated our home and garden, a timetable that worked for both parties, and a sale at over the asking price. And Karen’s support doesn’t stop there. She helped with moving and relocation advice, brought us the check from the closing, and has continued to check in to see how we’re doing with our next adventure.

If we had another home to sell, KAREN TANZER would be our realtor of choice! When she sold our home, Karen got together with us 2+ months prior to our target time to put it on the market. She suggested what we'd need to do to attain our target sale price, including what needed to be removed from our home and what work we should have done to deliver the best return. Her suggestions were right on target. Her suggested vendors were wonderful to work with, provided excellent work, fair pricing, and cleaned up after themselves. We signed a P&S with the buyer within just a few days after putting the house on the market. Our sales price was greater that we anticipated. Karen's middle name should be "Responsive." If she couldn't take our call, we heard back from her right away. Karen was always upbeat and pleasant to work with. We can't imagine having a realtor that could deliver what she did for us.Thanks, Karen!

Karen was an absolute pleasure to work with and she was there for us every step of the way. As first time home buyers we had lots of questions and Karen went above and beyond to answer all of them. We are also fortunate to have her negotiating for us because we got a home that we love at a great price! We are so happy to have worked with her and would recommend her to anyone we know looking to buy or sell in the area.

This transaction was our 3rd with Karen. She is very detailed oriented and knows the local markets very well. She sold our house in 1 day and 16K over our asking price. The transaction went very smoothly and that was because of Karen. I would highly recommend her to everyone.

When we first got together with Karen she told us she would “help us get through the process” of buying a home. I could not have imagined how true this would be! With unlimited access to listed homes on the internet these days, I initially didn’t know the benefit of hiring a realtor. Finding a home you like, is the easiest part of buying a home!
Karen was with us every step of the way from helping us find the best lender, walking us through the home inspection process, negotiating with the sellers, you name it! She was always available to speak with us, and always did her best to explain what was going on. She always set realistic expectations for us, and if she didn’t know the answer to a question she would always find out within the day. She even contacted the town we were moving to, to help us understand a betterment plan that we would be investing in!
I can’t say enough good things about working with Karen, and would highly recommend her to anyone looking for a realtor — especially first time home buyers!

My wife and I consider ourselves fortunate to have met Karen during our relocation to the Boston area. We knew little about the area, but with Karen by our side we found the perfect home we had always wanted in a community we’re excited to become part of. Karen took the time to understand what we were looking for, provided experienced advice throughout the entire process, demonstrated masterful negotiation skills, and helped with local contacts for some work needed on our home. It is without any hesitation that we would enthusiastically recommend Karen!
