Amy Huishu (buyer)


Hi Shirley,
you do get an A + for communication and your clients are very lucky to have you. Most agents aren't nearly as quick at responding in this market. I appreciate it and if other agents don't express it I'm sure they are appreciative too.

I recently sold my home. From this experience, I learned that selling home needs a lot of diligence, careful planning, and right strategies in order to get things right. Researching the house market, fixing and staging home, setting the right price, screening potential buyers, negotiating deals, and completing the escrow process are some of the crucial phases.

If these are not done correctly, you might end up overspending or even worse, getting a bad deal.
Having an experienced and skillful agent is a must.

Shirley was my agent and she is that perfect agent who is very well qualified to do all of those tasks.
She is very experienced, kind, diligent, and dependable. She is very detail oriented in doing every task.
She works very quickly. Got my house staged properly, listed on the market, and received multiple offers with record sales in that area.
More impressively, the whole process was done while I was overseas. Yet she set up everything that made it very easy for me to handle via internet.
Everything went very smoothly and flawlessly from day one until everything completed.
I cannot recall any single glitch or even the slightest problem at any time.
I am extremely satisfied with her performance and very grateful to have her as my agent.
I highly recommend Shirley to everyone.

Appreciation Letter:
When we started our house searching process, we did not know where to start. Whether to sell the first house or rent it out. I knew Shirley Mahashin, we had met in one of her open houses sometime back. I spoke with Shirley and she immediately started sending us emails of different house options to look at.

Shirley guided us throughout the process; from bank loan, to selling our old house, to buy the new one, which required good coordination and quick movements between selling our previous house and buying the new house. Shirley's experience in the field and her honest advice, her guidance and her suggestions helped us make the right choice.

I would highly recommend Shirley Mahashin as a real estate agent for many reasons. The most
important of these reasons would be her commitment to her clients, her flexibility, honesty, and understanding the needs of her clients.

Lobo Family /Sellers and Buyers
(Dipa, Benedict and Aatish)

Shirley worked with my family for 6 months. We needed a new home in the Cupertino Elementary school district. We averaged seeing 3-5 homes per weekend and she never tried to rush us or "talk us" into anything. Our taste and needs were very specific. She helped us find the perfect home at a great price.
We were honored to work with her and her partner for 6 months and couldn't be happier with our new home. She fought hard to help us get the home we wanted and continued to be our advocate throughout the entire process. She's also given us great leads for termite work, flooring, etc.

Re: The successful sale of my property at 150 West Edith Ave #18, Los Altos 94022

Dear Shirley,

I have been involved in all aspects of real estate and have been quite successful as a RE Developer, CA Broker, and syndicator. I have brokered properties myself and was in fact a Coldwell Banker associate in the past; please recall that I met you at the CB branch in Sunnyvale. At that time, you were an aspiring agent. As such, I have seen in you a great potential with your perseverance, smartness, and love for the profession, among others.

My life has been overwhelmingly busy in the last 7 years doing RE development and had been thinking of selling my residence at 150 West Edith. I hardly have time for anything personal and so my problem was: who is that most qualified, competitive, trustworthy, intelligent, market-strategy-oriented, capable, ethical etc. that could market my residence?

It was you - Shirley - that came to mind. And indeed, you exceeded my expectations! Am grateful to you for selling my home for far more than the asking price and making the selling process that I thought was really tedious seem easy using your professional experience. I would recommend you to anyone who is looking for a Realtor for Life.

RE Developer/ Cal BRE #01234415


I have worked with Shirley on two of our investment properties - one in San Jose and one in Menlo Park over the period of 2+ yrs. She represents well professional knowledge in those areas and keen on researching the current market trend for us to make profitable suggestions.

She is also very responsive and patient for every little inquiry that I made, explaining in objective details of the pros and cons. More, she continues to respond my inquiries even we have closed the deal and sold the houses already, providing excellent service.

It is hard to find an honest and responsible realtor as most people would claim. However, I can assure you that Shirley not only possesses professional capabilities but also ethical manner towards her job. Plus she is a senior Realtor who owns many certificates and qualifications. I highly recommend her whether you are purchasing houses for your home living or investment purpose. You are very lucky to find her as your Realtor I would say that from my heart.

Chien H/ Seller and Buyer

Shirley Mahashin is a fantastic real estate agent. Her integrity and high personal standards make her a very rare person in this field. She places the interest of her client in getting a home that the client is happy at the top. Unlike many real estateagents I have dealt with, who want to "close" and move on, Shirley acts in your best interest, advising you of her opinion of whether a property would or would not best meet your interests, even if it means a quick sale and commission for you.

She is not pushy like many real estate agents, but at the same time, she advises you honestly about market conditions. I whole-heartedly recommend Shirley Mahashin as an outstanding real agent to anyone. I would be delighted to get her services again.

Bindu M /Buyer

We are very lucky to have Shirley as our agent for home purchase. She is not only a professional and experienced expert in the real estate field, but also more like our sincere friend to always give useful suggestions on our side. She never pushed us to recklessly offer a price, and always helped us thoroughly analyze the pros and cons of the property. Every time when I wrote email to Shirley for help, she was very responsive to get back to me instantly. Even after closing, Shirley still kept giving us much help and suggestions on moving and modeling arrangement.

We are grateful for all the help Shirley offered to us in the whole process. We
would highly recommend Shirley without any hesitation.

Miao Zhao /Buyer

To Ms. Mahashin's Manager,

I just want to express my gratitude to Ms. Mahashin for assisting me in selling my house. She was very responsive to my needs and kept me informed of all the developments throughout the process, from the beginning to after the sell. Since I work late, she would meet me in the evenings if I needed to sign papers, and she would meet with the contractor, stager, appraiser, and termite inspector during the day on behalf of my interests. Ms. Mahashin stayed on task with the buyer's agent and lender to ensure that closing would occur timely. In fact, we closed 35 days after the house was listed.
I'm very pleased with all the hard work and dedication that Ms. Mahashin exhibited, which I believed attributed to the quick sale of the house. I would whole-heartedly recommend her to my friends or anyone who is looking to sell their house.


Don Vu /Seller


Shirley helped me buy my first home. She treated me like a family member when we looked for a house. In a fast-paced real estate environment in Sunnyvale during the spring, she was patient with me even though I took 3months+ to settle on a house.

Throughout the process she would do the homework and find great candidate homes, even visiting some of them before taking up my time. For each home, she would help with the due diligence as well after I indicated interest. This is a stark difference compared to another broker I tried in the past that was just interested in pushing for a sale.

Her knowledge of the closing process and industry expertise helped close my transaction smoothly and with very minimal work to do. I would highly recommend her to anyone who wants a personal touch.
Benedict C /Buyer


Shirley Mahashin is a great Realtor and my husband and I would highly recommend her. We truly felt that Shirley listened to our needs and wants for a new home. Her job was incredibly challenging, given the conditions of the current Bay Area housing market. She patiently worked with us for months to help us find not only the perfect home, but the perfect neighborhood in Menlo Park. She also offered terrific recommendations for lenders, contractors, and movers.

We are 100% satisfied with our experience with Shirley. She was extremely attentive and always responsive when we had questions or wanted to see different homes. She's an extremely hard worker and is willing to do whatever it takes to make sure her clients are happy!
R. Huynh /Buyer and Seller


As sellers of a home in Sunnyvale, we feel very lucky to have selected Shirley Mahashin at Coldwell Banker as our agent to assist us in selling our house.Coldwell Banker is really a prestigious Residential Brokerage that we can count on.

We attributed the success and smooth sailing of our transaction to Shirley Mahashinrsquo;s highest level of professional service. During the selling process, whenever problems arose, be they big or small, Shirley would go to the greatest length to proactively and tirelessly contact the parties involved to solve the matters. Shirley not only advised us and suggested various reasonable and constructive way-outs to any issues, but she also negotiated the win-win solutions for both sellers and buyers. In short, Shirleylsquo;s hard work and professional attitude are the strong foundation for the smooth sailing of the transaction under current mortgage and buyer's market situation.

Once again, we would like to express our gratitude to Shirley for her honesty and dedication to her clients.


Bill Chow /Seller

Hi Shirley,

First of all, THANK YOU VERY MUCH for representing us in this transaction.

We are extremely pleased with your very efficient service. From the beginning pointing us to the opportunity of buying an REO, guiding us through the process, being always there to answer our questions, concerns, and even helping us to promptly get inspections, estimates for fixing work, keeping us informed of every single step in the process, sending us reminders of what we needed to do, chasing our lender, and all the actions that throughout the whole process you did in a VERY efficient way.

We really enjoyed working with you and your kindness and flexibily to meet us whenever and wherever it was convenient for us made things much easier. One thing that we particularly appreciate is that we always had the feeling that you REALLY CARED for the best for us. You never pushed us, and actually you helped us to keep our offer at a good level so that it resulted in a good investment for us. Moreover, you were always on top of every single detail so that we had the confidence that we were in very good hands.

In brief, we were thrilled by your service and without any doubt we will recommend you to any friend and colleague that is in search for a home.

Many thanks again and also for the very nice and thoughtful gesture of the escrow closing gift.

With our great and sincere appreciation and gratitude,

--Malu (on behalf of Manolo and myself) /Buyer


Shirley helped me buy a home!

I met Shirley at an open house she hosted, and she gave me the impression as an honest, reliable, and very knowledgeable Realtor. Later on I asked her to be my agent, and she provided a great service to help me find and purchase my first house. Shirley consistently gave me sound advice based upon her past experience and history which allowed me to make the best decisions. Being a first time home buyer and very busy with my own work, I thought all the paperwork/process of buying a house could be stressful task. However Shirley is always very patient and comforting. She is very organized and reminded me of every details and deadlines along the way. This helps me tremendously.

Thank you Shirley for your great help.

Jeff Zhao /Buyer


I just bought a house last month with Shirley as my agent. She is one of the most helpful and professional agents I have ever encountered. Whenever I had any questions, she would always be available to help me answer them. At every step of the way, she was there for me. Even after the house closed, I was still able to go to her with questions. She treated buying the house like she would have if she were buying her own home. I highly recommend Shirley for her dedication and expertise!

Suxia /Buyer


My friend recommended Shirley to me. At the time, we had already visited many open houses for 2 months but we did not find the one we liked. She gave my wife and I the impression as a very knowledgeable and reliable Realtor. Within a few days, she helped us find the property we liked in Sunnyvale. She also communicated with the listing agent several times to make everything go smoothly.
After we got the property, she also recommended contractors to help us fix various issues.
In short, both my wife and I think she is a very professional and reliable Realtor. We would highly recommend her to everyone!

C Zhong /Buyer


We gotta give our heartfelt thank you to Shirley. We were working with another agent before we met Shirley. At the time that we were looking to buy our first home, it is a very competitive market and our first agent would only ask us to bid 20% up for everything. In contrary, Shirley used her experience and local knowledge to help us make a successful bid at a good price.

She also go out and helped us to negotiate with seller to put down more protection for us. And I found Shirley is pretty resourceful, there are times that the lender would come up with an urgent requirement. She would be able to give us the contact referrals and co-ordinate to get things done on the same day.

Highly recommend her. Cannot imagine what would happen if we stuck with the first agent we met. Feel so lucky to have her help us for our first home purchase!

Julian Wong /Buyer

Dear Shirley,

Thank you so much for your help in helping me to purchase my first home!

My parents and I all felt it was a blessing from God to be able to meet you at that open house five months ago!

Since that time we have been through some high and low times, but through it all, it now feels like we have been good friends for years!

Thank you for your hard work and perseverance.

I hope we can keep in touch, and visit my home some time!

Enoch W /Buyer


My previous bad experience with some real estate agent has caused me to be cautious when dealing with real estate associates.

When I first met and interviewed Shirley Mahashin, I realized that she possesses the knowledge, integrity, skills, honesty and professionalism to represent me to sell my home. My decision to have Shirley be my listing agent has proven to be a sound one.

In every step of the selling process, she put my best interest at heart and worked hard to market my home; in addition, she updated and advised me with every development of the transaction. There is no surprise that my house was sold at over the listing price and within a very short time.

I will definitely refer Shirley Mahashin to you if you are considering listing your home, because not only does Shirley help you arrange all the necessary preparation for putting your home on the market, but she also guides you through every step of the selling process until escrow closes satisfactorily.

Frances Ramolette Harlyn Caruso /Sellers


Shirley is excellent. We were first time home buyers and Shirley held our hands through the whole process, from placing the bid to closing.

Dara Debra / Buyers

Aiguo /Buyer


My husband and I first met Shirley at one of her open houses, she was extremely professional with a warm personality.This was our first house , so we really needed to find someone that could help us navigate the market.We were amazed at her dedication to finding the house that was right for us and our budget.

She found us great deals, wonderful contractors, followed through on all promises, and negotiated the best deals for us. She also reviewed properties in advance, met and communicated with us at times that were convenient to us, and clearly explained the process and documentation. We knew we were in good hands, and our lives were made easier because of her dedication.

We feel extremely fortunate that we met her, and found a house that we feel will truly become our home.
We wholeheartedly recommend Shirley whether you are buying or selling.

Best regards,

Dear Shirley,

Thank you very much for helping us to find a perfect house. We are
lucky that we found you to help us look for our house.

I came from Japan and I have been living in USA for 8 months. Although my English is not perfect, you were so nice to me.

This was the first time I bought a house in USA, so everything was new to me. You guided us through all the steps to find and buy a good house.

I really appreciate that you took care of me as if I am your sister. We felt comfortable and were very satisfied with your sincere service.

With her knowledge, experience, and skills she knew what kind of homes we would like to purchase. In less than two months we have bought our dream home in our desired area.

As first time home buyers, we are grateful to be referred to a Realtor®; like Shirley Mahashin who places her clients' best interests as her foremost priority, and having her represent us in the home buying process has educated us to become sophisticated buyers.
