I had two exceptional experiences working with Karen. A few years ago, I sold a rental property. Recently, I sold my home of more than 30 years. It was in need of updates, repairs and still way too much stuff inside. Karen knew my priorities and helped make it a quick and hassle free process. Besides those benefits, she was able to assist in selling with that stuff left inside. The house sold for more than I expected or could have gotten with any "as is" companies. Definitely 5 star quality service.

My wife and I were looking to buy our first house and Karen was fantastic through the process. She did a great job helping us find the perfect house, writing a competitive offer, and guiding us through closing. As first time buyers it was reassuring to have someone with so much expertise on our side. Karen was responsive, friendly, and knowledgeable. I will definitely recommend her to anybody looking to buy a home!

Karen was super helpful along the way to becoming a first time home owner. She is very responsive, patient, professional, and pleasant to work with. One of the lenders she recommended was able to get me an excellent rate which allowed for a little more flexibility in the budget. Overall a great experience and happy to have found her.

Karen was great to work with both selling our old home as well as buying our new one. I would highly recommend her to anyone!

Karen is so knowledgeable and helpful--it was a joy to work with her! She is a great communicator and knows her market inside and out.

We initially reached out to Karen per a recommendation from Reddit and have been pleased with her expertise, professionalism, and kindness. We’re first-time home buyers and hesitant about the process, but at our first meeting Karen took plenty of time to ask us questions and learn about us and what we needed. Fast forward one month and we're preparing to close on our first home! She was able to answer every weird question we had, gave us great tips on what to look for, pointed out all kinds of stuff about the homes we saw that we never would have thought to consider, and helped us write a winning offer. Her office is in touch with us regularly with updates about where we are in the process, which I appreciated a lot. We had no idea what we were doing when we got in touch with her but now we’ve got a solid plan in place and are excited to move in. I recommend contacting Karen if you’re new to this stuff and looking to buy in the Milwaukee area.

Karen is an experienced realtor who took time to gain knowledge and history of the property. She was kind and knowledgeable while explaining the process. She has a great personality and knows the market. In addition to Karen, she has a great team and they all give regular updates and make sure the client knows what to expect next.

We have known Karen since we bought our first house with her almost 10 years ago, and we just worked with her again to buy our new home in the same Bay View neighborhood. Karen is awesome - she has a ton of experience and knowledge about the houses and market in our area. We really appreciated her honest advice, and how quickly she responded to our texts or emails. She even stopped by while walking her cute pup one evening to answer a question that I had about our offer. Karen was great at helping us navigate the whole process from the showing, through our offer and counteroffer, and our successful closing. We would definitely recommend working with Karen!
10/27/2021

Karen does an amazing job! She has helped us buy and sell several homes and is very thorough and patient. She is in constant contact with us throughout the process. I highly recommend using her services.
08/04/2021

As first-time homebuyers in the 2020 housing market, we were glad to work with Karen. Karen understood our desire to remain patient to find the right home while balancing the need to act quickly in the real estate environment we were in. We appreciated Karen’s work ethic, especially when we needed to schedule showings and make offers the day that houses were listed. Karen was great at facilitating conversations about features of homes we saw and helped us refine our preferences over time. As a final testament to Karen’s expertise and client focus, she persuaded us to see a house that we initially didn’t have interest in but had features she knew were important to us. As soon as we stepped inside, we knew we had found our home! We were guided smartly through the offer and negotiation process and are loving our new home!
01/06/2021

Karen is an exceptional agent, from initial contact through closing. We have worked with her on both the buying and selling sides, and we couldn't imagine having had to work with someone else. When it comes to preparing to sell, she has contacts for getting the work done, and is even willing to work with them herself to coordinate execution. When it comes to buying, she knows what to look for and how to negotiate, keeping your best interest first and foremost in mind. Most recently we sold a property in Bay View and it sold for more than we were expecting, thanks to her advice and attention to detail. Not only did she recommend we list higher than we expected, but we received multiple offers the day after listing, and accepted an offer above asking the next day. Bottom line, she is the best you could ask for.
04/28/2020

It was a pleasure to work with someone who truly listens to their clients and genuinely has their best interest in mind. Karen was a great adviser when there were questions and made the searching and buying process a pleasant experience.
08/19/2019

I would recommend Karen in a heart beat. She was awesome to work with. Always willing to answer any and all questions to make our experience as stress free as possible. When we are ready to purchase a home we will definitely work with her again.
04/09/2019

Karen has helped me purchase 2 homes since 2010. In a market where homes were selling in less than one hour Karen's knowledge, commitment and connections were crucial to our success in purchasing a home. I would recommend her for anyone looking to buy a home.
11/15/2017

Karen is kind, easy to work with, extremely knowledgeable, and truly cares about her clients. As first time home buyers we were very intimidated by the home buying process (and the current state of the market), but Karen took the time to answer all of our questions and was there with us every step of the way. We always felt that she had our best interest in mind, genuinely cared about our experience and was determined to help us find the perfect home. We will definitely recommend her to anyone searching for a realtor!
06/30/2025

We were searching for an agent who could help us find our perfect condo and Karen was outstanding. Found Karen on a web search of realtors who specialized in remote view, offer and buy and who was very knowledgeable about the neighborhoods that were best for us. As out of state buyers we needed someone who gave us great insight, quick responsiveness and expert opinion about our purchase in Milwaukee. We retained her as our Buyer agent and are grateful for her assistance with our purchase process. Her follow-through and representation of her buyers is top-notch. 5 stars!
06/13/2025

Karen took us under her wing after attending an open house and was so supportive while buying our first home! Thank you Karen for your expertise and making us feel comfortable throughout the process!

I wanted to take a moment to express my admiration for Karen Block, even though I haven't had the opportunity to be her customer just yet. As the owner of a painting business, I understand how important it is to have trustworthy and reliable partners. From a vendor's perspective, it can be challenging to find individuals who truly appreciate your hard work and value your labor. However, working with Karen has been nothing short of incredible. Karen's honesty, openness, and directness are qualities that I highly respect. She is a woman of integrity, and her professionalism shines through in every interaction. As a vendor, I appreciate the way she treated my painting business with honesty and respect. If Karen can demonstrate such qualities towards a vendor like myself, I can only imagine how exceptional she must be in her interactions with buyers and sellers. I consider it the highest compliment to acknowledge Karen's honesty, level of respect, trust, and professionalism in her field. If you are in the market as a buyer or seller, I wholeheartedly recommend working with Karen. Her commitment to honesty and her ability to build trust are invaluable assets that will undoubtedly enhance your real estate journey. Thank you, Karen, for embodying the values of integrity and professionalism. I look forward to the day when my painting business becomes more profitable, and I can work with you as my realtor.

Seamless... from prep, to set up, photos, showings, inspection and appraisal, to closing. Karen was there for us through it all and got the job done! She listened to us and communicated through the whole process. I would recommend Karen to represent a seller ANY day! Easy, smooth and great transaction!

Deciding to buy my first house in 2022 was part of my five year plan. However, the pandemic and other forces sure didn’t make it an easy time to wander into a new home. Karen’s skills and experience are the reason I was able to win on the home that is just right for me. Karen patiently walked me through every step, empowering me to understand the process and ultimately craft a winning offer unique the market conditions and my financial circumstances. She answered calls late into the evening and first thing in the morning. She patiently met my whole family and politely considered their opinions, too. And ultimately saw me through a deal with a unique seller. I’m glad I didn’t give up! I haven’t moved in to my new home yet but I’m working on making it a stunner. Karen helped me see it’s potential, including the beautiful hardwood floors hiding under the carpet. Karen’s experience working and living in Bayview was the perfect fit for me. I highly recommend her!
04/18/2022

Karen Block is very professional and experienced. She walked me through the whole process of selling my home. I received weekly updates and scheduling confirmations on showings. She answered all my questions promptly...never left me guessing. Absolutely wonderful to work with! I got top dollar for my home...thanks to Karen :)

Working with Karen has been an absolute delight from start to finish! My husband and I are first time homebuyers with an FHA loan and we sure chose quite the intense market to buy in. Despite that, we managed to find the home of our dreams in less than 2 months from when we started touring houses and we just moved in last week after an incredibly smooth contingency and closing process! Karen was incredible at guiding us to hone in on exactly what we wanted, needed, and maybe what we didn't need. She kept us realistic about what was affordable for us while also guiding us on what is worth investing in. I cannot express our appreciation enough for keeping our desires top of mind while simultaneously balancing out our budget and loan restrictions. Ultimately, we only ever ended up putting offers in on two houses, the first one deciding not to sell, and the second one being the winner! She is an aggressive finder and closer, and she works her magic with kindness and thoughtful consideration. I cannot stress enough how easy she made this process for us - we experienced none of the horrors of homebuying that everyone always tells you about and I firmly believe that is because of her, as well as our mortgage broker who she referred us to. She knows her stuff, just sit back and trust her to take care of it!!! So much love and thanks for everything!! Emily Jane and Justin (and tail wags from Juniper!!) PS - another super sweet touch : she made sure to get gorgeous photos of us for our accepted offer and closing days, and it just adds to those little details that she pays attention to! Now we will have those photos to look back on and smile :)

Karen is the best! Worked with us very closely throughout the entire process and was very prompt and responsive at all times. Very personable and made the entire process very stress-free, even in a highly competitive housing market. Highly recommended!
07/26/2021

We have bought and sold our house with Karen and we don’t consider going to anyone else. She is flexible, she listens, she is quick to respond to questions (no matter how silly they may be), and she will go the extra mile to ensure you feel comfortable with your choices and decisions. My husband and I were new homeowners and she guided us with the little “tricks of the trade” to look for when buying or selling a home. I cannot thank her enough for all she has done for us! I highly recommend her to anyone and everyone :)
06/30/2020

Great agent! Has the best advice and knowledge to get a house sold.
09/16/2019

Highly recommend Karen. We had an amazingly fast and efficient process with Karen. She was with us every step of the way, honest throughout the process, answered every question we came up, was patient with us as the buyers, and was just as excited for us as we were when we found the one.
08/19/2019

Karen was excellent throughout our whole buying process. She kept us informed and explained each step of the way! She took the stress out of the entire process of buying a home. She was easy to reach whenever I had questions about what was going on. She was very knowledgeable about the homes we walked through and seemed to know what myself and my husband was looking for. She was not trying to just sell us a home but was more interested in finding OUR home. The best part is she found one so close to our family!

Karen helped us buy our new home and sell our old one. Each was tricky in its own way and Karen's experience and persistence proved to be invaluable in both processes: We bought our new home off the market in a desirable neighborhood. We chose Karen to represent us because she is very familiar with Bay View, which can be quite competitive. Friends who had bought and sold in Bay View recommended her to us. Her intimate knowledge of the area and her friendliness with other local agents meant that, when we found the perfect home that we knew would be for sale soon, she was able to negotiate the sale for us before the house even hit the market. The transaction was as smooth as can be and, while the price we ended up paying was likely commensurate with what it would have gone for on the market, getting the house we wanted without having to risk the uncertainty of the market was priceless. (Turns out she helped our neighbor across the street from this house buy their house too. It was nice to have that point of connection right off the bat!) Selling our previous home was a whole different animal and, here too, Karen's steady hand and anticipation of potential problems made all the difference. This house is a historic mansion that we've been renovating for the past six years. It's a beautiful monster of a house and a project that will never truly be finished. For the right buyer it was going to be an absolute gem but, for most people, it was not going to be a good fit. We knew from the beginning that the process of finding the right buyer might be hard: it would require patience and grit. Karen was absolutely up for the job. She helped us decide which ongoing projects needed to be wrapped up before listing and which would not provide any further return on investment. She took the time to understand the uniqueness of the house and, by the end of the process, she was attending every showing in order to sell those unique features. She helped us unravel some outstanding building permit issues that were tied up with city. I kid you not, she was over at the house with a fly-swatter when we had a random outbreak of flies (gross) before an important showing! When the house was under contract she helped the buyer's agent, who was less experienced, handle their lender which was making all sorts of ludicrous demands. Most importantly, she got the deal done despite a number of setbacks. I think Karen has been in the realty business for around sixteen years and the benefits of that experience were obvious. When our old house closed, we went out to lunch to celebrate and she asked us what we thought she might be able to do better next time. First of all, we were at a loss for any substantive input here, but also, the fact that someone with her level of expertise even asked this question is a testament to the type of person that she is. She cares about her clients and understands the gravity of the situation that home buying/selling is. She wants to help people get themselves not only into a home that they love but also into good financial footing. When all was said and done, I think we spent about nine months working with Karen and the more we got to know her, the more impressed we were.

I had the pleasure of working with Karen as our realtor, and the experience was truly exceptional. Karen's professionalism and courteous demeanor made the entire process seamless and enjoyable. She took the time to understand our preferences and needs. What truly set Karen apart was her ability to source off-market properties. She delivered a stunning home that wasn't even on our radar, showcasing her dedication to finding the perfect match for us. If you're in search of a real estate professional who goes above and beyond, Karen is the one to choose! Highly recommend.
12/13/2023

While the market was rocky, Karen was always reliable. She helped us through the process of selling our house, for over list price AND helped us find our forever home within our budget! She is very knowledgeable and professional. I would recommend her to anyone looking to buy or sell a home in the Milwaukee area.

If you need a realtor call Karen Block! I came to WI in late November hooked up with Karen and had a new home in January. Karen listened and found what I was looking for. She is knowledgeable, professional, and caring.
02/14/2022

As a Mortgage Loan Officer I've known Karen for nearly 10 years. She is knowledgeable and savy. Over the years I've confidently referred my clients, friends and family to her. I have always recieved they're gratitude for connecting them with Karen.
