With over 41 years of experience, I have been helping buyers and sellers achieve their real estate goals. I am proud to be recognized among the Top 1% of REALTORS® in Santa Clara County and the Top 1% of real estate professionals nationwide through RealTrends Verified rankings.
While I specialize in single-family residential real estate, I also have extensive experience with multi-family properties, commercial real estate, land development, vacation homes, relocation services, short sales, and REO properties. My goal has always been simple: to help my clients achieve their real estate dreams. When my clients succeed, I succeed.
Throughout my career, I have been actively involved in the real estate community. I have served as a Director for both the Santa Clara County Association of REALTORS® and the South County REALTOR® Alliance (SCRA), and I had the honor of serving as President of SCRA in 2019. While I am grateful for the awards and recognition I have received over the years, my primary focus has always been my clients. I believe in treating every client the way I would want to be treated, with honesty, respect, transparency, and exceptional service.
My clients benefit from my outgoing personality, strong communication and negotiation skills, and in-depth knowledge of the local market and ever-changing real estate industry. Just as importantly, they benefit from the relationships I have built over decades with some of the best professionals in the business. These connections, combined with my experience, help ensure a smooth and successful transaction from start to finish.
Whether you are purchasing your first home, moving up to accommodate a growing family, downsizing, investing, or selling a property, I am committed to making the process as smooth and stress-free as possible. I keep my clients informed every step of the way so they can make important decisions with confidence and peace of mind.
For sellers, I offer proven marketing strategies, maximum exposure, and a powerful professional network designed to attract qualified buyers and maximize value. For buyers, I provide expert guidance, strong advocacy, and the market knowledge needed to navigate today's competitive environment successfully.
Real estate is more than a career for me. It is my passion. I sincerely care about the people I serve and strive every day to be the very best I can be. I am committed to continuous learning, professional growth, and delivering the highest level of service possible. This is my full-time profession, not a hobby, and I would be honored to put my experience, dedication, and expertise to work for you.
Let my experience help make your next real estate experience a successful one.
I had the pleasure of working with Karen Nelsen in February 2025 when she was the listing agent on a gorgeous Gilroy home. We had a smooth and easy escrow thanks to her due diligence and quick and friendly support. I was happy to be the lender for the buyer of her listing, and now we have happy families—all around. I highly recommend Karen as a long-time, hard-working professional agent who knows her market and is a pleasure to work with!

Hi Karen, just wanted to let you know that the funds have successfully arrived and everything has cleared on my end. I really appreciate your help throughout the entire process—it’s a relief to have everything completed smoothly. Looking back, I also want to thank you for your support a few years ago when you helped me purchase this same house. It’s quite something to go from buying to selling the same property with your guidance on both ends. That kind of continuity gave me a lot of confidence, especially knowing I had someone experienced who understood both my situation and the property history. Throughout this sale, I appreciated how you handled the details, coordinated the process, and kept things moving even when things got a bit complex. It really reflects the value of having a consistent, knowledgeable agent who can support clients over the long term, not just at a single point in time. I’m glad I had that with you. Thanks again for everything, and wishing you continued success with your future clients.

Working with Karen was honestly such a great experience from start to finish. She helped us find a home that’s perfect for our family, and at the same time made the process of selling our old place feel way less stressful than we expected. She was always quick to respond and patient with all our questions. You can tell she genuinely cares about her clients and isn’t just there to close a deal. We’re so grateful for everything she did and would 100% recommend her to anyone buying or selling a home. Thank you, Karen!

Karen and her team are top tier. I did not know the home buying process could be this smooth. I wouldn't consider working with anyone else after my experience with Karen and her team, as they are truly industry experts and advocated for us at every turn. No details missed, no stones unturned; we could not be happier!

So many great things can be said about Karen and her team. This is the second time we have worked with them. They’re dedicated, hardworking, and will always go the extra mile when working with you. No matter how large or small your property, they treat everyone the same, making sure they are heard, valued, and getting the most out of them and their services. I wouldn’t go to anyone else if I were buying or selling; you don’t need to look any further! Give them a chance, and I know you will be just as happy as my wife and I were after working with them!

We had the good fortune to have Karen's advice and counsel on a recent real estate sale in Morgan Hill. We were very happy with the suggestions and assistance during the process of updating the property and preparing it for listing. We were able to get work done quickly and cost effectively using her extensive contact list of contractors and skilled craftspeople. She and her team assisted at every step. Definitely a successful and pleasant experience!

First class all the way! Karen was the most responsive and attentive real estate person we have ever dealt with. Always answered her phone calls and was one step ahead. Highly recommend using Karen for buying or selling any real estate.

Perfection! Stephanie and Karen are the dream team. We were a pain in the butt; I believe we looked at 20 properties before choosing our home, and they were patient and always made time for us. Their responses to us were so quick and helped us truly understand the process.

Quick and great ongoing communication, and a very hard-working agent. We would use Karen again for any transaction! She worked quickly to list, show, and complete our sale, and took the necessary measures to assure us that our deal went through correctly.

Karen was "on it" from our first meeting until closing. It's obvious that she is an expert and gets results. In our case, the first offer came in two days after listing for significantly more than asking. From listing to closing, Karen was there coaching, encouraging, and seeing to all the details. Would we recommend her? Absolutely! Thank you, Karen, for being such a reliable, trustworthy advocate!

Highly recommend! Have now been working with Karen and her team for four years, buying, selling, and signing leases with her help. This team is, in a word, gritty. They did not back down when our deal was difficult, complicated, or when the timing of new information came at Friday night at 9 pm. They were always on their game and willing to talk through their strategy. You name it, we saw it. This one had a lot of twists and turns, and we never would have made it to the end successfully without her professionalism and experience. I have an extremely high customer service standard, and Karen and her team set a new bar with their responsiveness, competence, and confidence in her strategy. We are extremely grateful to her and her team, and will recommend them to anyone who wants to see their deal get to the finish line.

I’ll trust her and Stephanie for our future home buying and selling.

Karen worked with us in a manner that was competent, reassuring, and respectful of our wishes. She is very experienced and presents options and suggestions that resulted in a very successful outcome.

Karen Nelsen is a great negotiator and worked tirelessly on our behalf. She worked closely with us every step of the way. She also knows many professionals who helped us with additional inspections, quotations, and professional guidance. Karen and her team have the pulse of the local market at their fingertips. Their communication throughout the buying process is phenomenal. Karen was referred to us when we moved to Morgan Hill, and she did not disappoint. One of the inspections turned up a concern on a retaining wall. Within two days, Karen dispatched a structural engineer and a contractor to estimate the severity and the repair costs. Timing was especially important as our contingency period was short. This was critical in the final negotiations. In the end, it was not a major factor, but it did help better the price for us. If anyone is interested in purchasing or selling a property in the Morgan Hill area, I am not sure how you could do any better than the Karen Nelsen team.

Thorough, thoughtful, trustworthy, and follows up. Sold our house in 4 1/2 days—unbelievable in what is becoming a buyer's market. Best selling experience I have ever had.

Karen and her team made me feel like part of her family. I was updated constantly and always felt like I was her primary client. I have used Karen to purchase my residence and to sell it. I will most definitely use her services again and recommend her to all my family and friends.
