I lived in the Aliso Villas for 31 years.  Finally I decided that it was time to move to a retirement community.  I had known Karen from the time that I moved into the villas since she sold many homes in the community and always stopped by to say hello.  When it came time to move, the logical choice was to call Karen – I was impressed with her real estate knowledge of my community.  She sold my home in record time and found a beautiful home for me to buy. 

Karen made the transition of selling and buying an effortless process for which I was grateful.  She was very professional, friendly and attuned to my needs – an enormous asset to the entire process.


The first time we met Karen was when we were buying our house and she was representing the seller. She did an excellent job for the seller and we were happy to work with her. After moving into our neighborhood, we found out that Karen’s reputation is outstanding among the other residence and we have run into her multiple times at neighborhood parties since then.  We recommended Karen to a friend and my friend was also pleased with Karen’s service. Just recently, we used Karen to sell our rental in Mission Viejo.  She gave us advice that ended up getting us $30,000 over our listing price. We did just enough work to our home to make a huge difference. My father is now selling a home in Irvine and I am happy to have Karen represent him. You will not be disappointed!

Karen is our realtor for life. We met her as the sellers agent when we purchased our first home, years ago. She just helped us last week close on our new home. Her talent and professionalism were key in making the deal happen. I recommend her for all real estate matters. From buying a home, selling a home or help with your rental property she is the right person for you.

My wife and I have known Karen Quinn for about 20 years.  We were managing out first investment property and we were recommended to her by a friend who had been in this business a while. He assured us Karen was hardworking and trustworthy. We worked with Karen on multiple transactions over the years and she has always lived up to the original recommendation.

In Spring 2013 we were entering into a complicated property transfer transaction with a tight timetable. We gave Karen a call and the following day she had several properties lined up that fit our requirements. We made offers on a few properties and ultimately bought one. Karen was patient, thorough, very hardworking and a great negotiator. She always made us feel like she was looking out for our best interest.  In those rare times Karen was not available, she made sure her assistant had the information available to help us. Looking back over the years working with Karen, we could not have picked a better Realtor to work with. Not only is Karen a great Realtor, she has become a trusted friend.

I’ve known Karen for more than sixteen years as a friend.  In 1997, I asked her to help me sell my home and later to find a great house for me at a perfect price.  SHE DID! And then several years ago, when my son Andy got married she helped him and his wife buy their first condo.  It was so incredible to watch her style and patience as she taught them about the real estate market. They learned so much.  Since then, the kids bought my house from me and sold their condo to Andy’s sister. 

I have seen Karen at her finest hour of negotiating, when my seller gave notice that she was backing out of a twenty-five day escrow over Christmas on day 20.  All I can say is Karen looks sweet and small, but she had that seller’s knees shaking and in full agreement to continue escrow.  Her expertise, ethics and experience all come together.

I met Karen one day in 1980 when she was walking her “beat” in the Aliso Villas area of Mission Viejo.  Soon I started noticing that there were several signs with her name.  One day I saw her ad saying “over 100 homes sold” then 200, soon 500 later 1000 now 1500?  Wasn’t there a hamburger chain that started like that?  Over the years Karen has helped my wife and I buy or sell over 15 properties.  She has always given us the benefit of her experience and her valuable counsel.  We have prospered as her clients and learned as her friend.  Her husband Marv managed our rental properties for over 10 years and always provided solutions and answers to tenant questions.  Karen – YOU ARE THE BEST!!!

Carol & Steve

Tina and I were overwhelmed with questions and concerns as we started looking to buy a home in South Orange County. This all changed when we connected with Karen. Our stress was relived and replaced with confidence as she brought clarity to our home purchasing situation. Don’t let her sweet demeanor fool you. She’s a skillfully, aggressive negotiator who will fight for you. Overall, our experience in buying a home with Karen was amazing as she helped place us in the house of our dreams at a super low price!  In the last two years we have referred six of our friends to Karen and all six of them have bought homes through her. They have all thanked us so very much for referring them to her.

Karen Quinn embodies every quality that a dream realtor should. We live in Canada and worked with Karen for over one year in order to find our perfect vacation home in Southern California. Karen was both an advocate on our behalf as well as a sound ambassador to the local market. Upon meeting with Karen, we quickly knew that we could trust her to steer us in the right direction. She went above and beyond at every stage of the process – from the start of our search, all the way through to the closing date and beyond. Karen made the transaction seamless and easy to manage, despite us living more than 2000 miles away. We would not hesitate to recommend Karen to anyone looking in the area – she is truly a wonderful person and an extraordinary agent.

I thoroughly enjoyed working with Karen Quinn when she recently sold my house at Monarch Point in Laguna Niguel.  What was very refreshing is that Karen is simply nice and straight forward which made everything just move forward without a lot of stress.  Not only did I appreciate that, but the buyer and his agent were clearly very impressed too.  When you add that to that Karen’s depth of experience and her commitment to making it a successful outcome, I can say with confidence that I was very fortunate to have Karen represent me in this transaction.


Over a two year period, agents from this Realty company helped us find a home to buy, which was not easy for them as we were probably nightmare clients.  We had very specific requirements and budget limitations.  Karen Quinn and her associate Monica Dean were 100% available to us whenever needed, and they never failed to provide us the appropriate expertise on properties in our search areas.  The possess a great amount of knowledge in the ares of Mission Viejo, Rancho Santa Margarita, Lake Forest and Ladera Ranch, which were our specific target areas, but I am certain they have even broader expertise in most of all of Orange County California.  I would definitely call Karen first if we have need for realtor services in the future.

Good friends recommended Karen Quinn, Regency Real Estate Brokers, Inc. and we are so thankful for the recommendation.  We had recently lost a family member and needed to sell a condo that was part of a trust.  Karen was the third broker/agent that we interviewed and upon meeting with her, there was an immediate consensus among our family that she would be our choice.  Karen met with us as a group and patiently, professionally, and thoroughly answered our numerous and frequent questions; providing sincere answers and several options.  We never felt rushed, nor pushed into a decision. 

She brought a great deal of knowledge regarding the current market and was also able to recommend wonderful trades people to assist us in getting the property ready for listing.  We are convinced that her knowledge of the market and her experience were the reason that we were successful in receiving an above-listing offer within one week from a very qualified buyer.  Throughout the process, Karen kept us updated – a feat not easy as we had several family members involved.  She promptly returned emails, texts and phone calls.  Despite the relatively low commission potential of our small condo, Karen’s professionalism and dedication was consistent.  

In short, we highly recommend Karen Quinn as a real estate broker. She is the model of real estate professionalism; knowledgeable, easy to work with, patient, thorough, and a great communicator.  We wouldn’t hesitate to use her services again in the future and recommend her wholeheartedly.

Karen was referred to me by a friend and a realtor in Rancho Cucamonga. I was interested in selling my beach house in San Clemente and buying another one that more suited my needs. For over a year Karen took me to see a number of homes until I found one right on the beach in North San Clemente . I knew that was it. She marketed and sold my current home in San Clemente and coordinated the escrow of the purchase of the new one so the two sales were seamless. She paid very close  attention to the details and stayed in constant communication with me.

I appreciated the fact that she and her team made every effort to take care of things for me since I was not living full time in San Clemente. Later I sold this home in North San Clemente and, of course, Karen was the one I called. She has become a trusted advisor and a friend. I would easily recommend her to anyone looking to sell or to purchase.


My wife and I were in the market to buy our first home. This was something we thought about a researched for quite a while. The whole process still seemed overwhelming, though. We decided very early that we would like to work with a realtor that had years of experience within the industry and within the neighborhoods we were looking into. This is why we chose Karen Quinn with Regency Real Estate Brokers. We were turned onto Karen by my wife’s parents as Karen frequents many neighborhoods in Mission Viejo. Karen visits these neighborhoods and has really created many lasting relationships with current and future homeowners. That was important to us.

We met with Karen, discussed budgets, locations, timing and all the other details of the purchase. Karen really listened to what we wanted and what we didn’t want in a home. Over the next couple weeks we probably looked at no more than 10 homes with Karen before we made a decision. Karen really did a great job on selecting homes within our budget and within the neighborhoods we wanted to live in. Karen’s knowledge of homes within this area is top notch, we were able to rule out several homes based on this. Without her, I think we could have made the wrong decision and we could have been stuck with a home that needed very costly repairs or worse.

After we made the decision on which home to pursue, Karen and her team walked us through the home buying process step by step. I would say we needed a little hand holding and reassurance as we were first time buyers. All these new terms, deadlines, inspections, forms, etc, were enough to make our heads spin. However, Karen and her team were always there to answer any questions we had, and we had many. I can’t imagine going through this home buying process without Karen and her team there at Regency Real Estate.

I would highly recommend Karen Quinn at Regency Real Estate to anyone looking for a home. She is very professional, always available and has the years of experience needed to properly help anyone choose the correct home. Her vast knowledge of the homes built in this area and the construction techniques  used throughout the years is an invaluable tool. I will personally use Karen Quinn and her team again in the future.

I am thankful for all the effort Karen put into selling my late mother’s home in Mission Viejo.  This was a very trying time for me and she made it much less stressful.  Since I live on the East coast I was unable to attend to the property in person.  Karen went the extra mile to attend to affairs that would normally be my responsibility.  These included assuring that the entrances to the home was protected against the deluge of rain that was recently experienced there, among numerous other smaller tasks on my behalf.  I feel like I have been very fortunate to have had you as my real estate agent. 


Home sale is a daunting ordeal and Karen made it very seamless.  For every small detail that came up Karen had an answer or got one at the earliest possible moment.  I will definitely recommend her to all my friends and family.  We are so pleased at how quickly she sold our home.  Thank you Karen for your expertise and professionalism.  


Karen left her notepads on my porch for years and the one thing I always noticed if I happen to see her was how pleasant, friendly and never pushy she was.  This spring I was busy at my house one day when Karen showed up on my doorstep with her usual notepad.  We had a brief conversation about my house and afterwards I knew the time had come to look into the selling of my home.  She was absolutely great! She told me to take my time before listing my house because it was a huge decision for a single Grandmother like me to make, and I so appreciated this.  When I was finally ready we listed my house and it sold quickly.  She took so much of the frustration out of the selling process and went over and above the call of duty to see that I came out with the amount of money she quoted me.  What a true blessing it was to have such an angel for my agent.  Here I am now in my new forever home loving it more with each passing day and what I want people to know is that Karen made it all possible.  I thank her for everything and love her not only as my agent but also as the kind, generous person she is.  She will make you very happy and like me, you will be lucky you chose her for your agent. 


For years Karen Quinn has helped me with my rental property in the Aliso Villas. She and her two wonderful assistants have wisely handled some difficult tenants. Throughout my time as a landlord and during the sale they held my hand and took the stress away from me. Karen’s wisdom and experience saved me money in not making costly decisions. She is worthy of a referral.


We are pleased to provide this recommendation of Karen Quinn. Karen has kept us informed on real estate matters and has answered our questions for more than 20 years. When we finally decided to sell our home this year, she advised us on ways to make it more appealing to prospective buyers and she counseled us on terms of the listing.  Our home sold within a week but that was followed by more than a month of inspections, gegotiations regarding repairs and mountains of paperwork.  Karen was marvelous throughout this process.  She was always redily available, responsive and professional. She was able to keep us calm and focused during some very stressful steps in teh process of completing the sale.  We would probably have walked away from the deal if it were not for her sensitive counsel.  We can recommend her to you without any reservations. 

Bob & Barbara 

 We used Karen Quinn to sell our home and she was outstanding in every way.  Karen gave us suggestions and ideas to make our home more desirable to buyers, and it really paid off.  She sold our home quickly and handled the details like the professional that she is.  From the marketing to the close of escrow Karen kept us informed and we always knew where we were in the process.  Her communication and updates made us feel at ease from start to finish.  Everything was handled without a hitch.  We highly recommend Karen Quinn if you are selling or buying your home. She will take care of your every need.

 In October we closed escrow on my dads condominium in Mission Viejo. This past year has been hard and stressful for me and Karen was able to give me amazing peace of mind from the moment I met with her.  She gave great advice on how we could quickly list the condo and make substantial profit. She walked me through every step of the way and was always patient with me and my million questions. I would go to her with any future real estate needs I might have and would highly recommend her to anyone looking to sell any type of real estate.

When conducting a transaction as important as one in real estate, it is of the utmost importance to work with someone who is not just qualified to do the work, but someone you trust, and trust is one of Karen Quinn’s most salient traits.  I have known Karen for over ten years and there was never a doubt in my mind that she would be at the helm when I decided to sell my property.  Karen ensures that her clients’ interests are protected and provides wise and thoughtful guidance with an unmatched level of professionalism.  Should I ever choose to purchase property again in Orange County, it will be through Karen.
