Michael has been our realtor for many years!

We've bought our Morgan Hill house with his help and sold another property with him in Menlo Park. Very knowledgeable, flexible, fast to react, honest and trustworthy partner for all your real estate needs!

He also sold our Morgan Hill house and the transaction was very pleasant and easy! That was our third transaction with him.

Michael, we can't thank you enough for all your hard work, dedication and time spent on our rental property. You took out all of our stress and handled everything from co-ordinating with the tenant for a move-out walk-thru to advertising and screening potential renters! Working with you was a real pleasure. Thank you.

This is a second review in 2024. I had such a pleasure of working with Michael who went above and beyond to help with all my property needs. Not only did he assist me in renting out property, but he also helped me with buying, selling a recent 1031 property. He was extremely knowledgeable about the market and was able to provide me with valuable insights and advice throughout the entire exchange process. The 1031 exchange went quickly and smoothly. Looking forward to working with you again.

Michael and Helen are absolutely incredible! It is never easy selling a home for the first time, especially after a loved one's passing, but they took the time to walkthrough the process and made it easy. Huge respect to them for always being considerate and supportive throughout the process. If you ever find yourself searching for an agent, then look no further.

As a first time home buyers, we couldn't have asked for a better agent. We had a limited budget that needed to be stretched to match our needs. Michael's patience, tireless efforts and keen attention to our preferences guided us to our new home. His professionalism, integrity and friendliness extended to the valuable contacts he provided including contractors, repairman and cleaning service that saved us much time and anxiety. We recommend Michael with much pleasure and gratitude.

Michael is absolutely amazing. He was very patient with me when I shopped for a property. He hand-picked some potentials for me and sent me the potentials with notes (E.g. unit has been upgraded, hardwood floor, nice curb appeal, good location, etc.) In short, he did a lot of research and he pre-screened the properties based on my criteria. Michael is very knowledgeable with the market trends and conditions. That's why I was able to purchase the property and closed the deal without any hassle. I appreciate his professionalism and highly recommend him without reservation. Finally, being friendly, kind, and caring also helps Michael to be a success in the real estate field!

Michael Koo has been our go-to real estate person for many years; he helped us purchase our very first house back in 1996 and he helped us buy and sell 3 more houses since then. Michael is wonderful, very professional, very patient and has a great know-how of the real estate world. Buying/selling a house can be a stressful experience, but Michael is very calm and confident, so for us every time we engaged in such transaction it was a very pleasant experience. We highly recommend Michael to anyone who is either a first time home buyer or a seasoned investor into a real estate market.
