Broker Associate / Partner, Interior Designer

As a real estate agent, I enjoy helping people feel at home in their new San Carlos CA house and neighborhood, whether they are relocating from across the pond or somewhere closer. I have firsthand experience raising children who went through the San Carlos school system and have gone on to be successful in college.

Most people can’t remember their realtor’s name, but my clients know my name because they hear from me on a regular basis through my client appreciation program. I know how hard it is when you don’t know anyone in your new surroundings, so I can recommend the best schools in San Carlos CA to my clients as well as local good eats, health care professionals and other community resources. I give back to the community by supporting other small business owners and am the leader of the San Carlos Chamber of Commerce Business Networking Group, for which I became the 2018 San Carlos Chamber Champion.

Broker / Partner, J.D., General Contractor

I am one of the luckiest guys in the world – I have a great family and I love my job! I always tell my kids to find something to do in life that will allow them to wake up each morning and look forward to their day. I’m very fortunate to have found that when I transitioned into real estate in 2003.

I’m extremely privileged to have the opportunity to assist people find the home of their dreams and/or transition out of their existing home. I do not take this privilege for granted nor the trust that my clients bestow upon me. People deserve expert advice and support, that is why I have invested a great deal of personal time and effort to develop valuable skills that better assist my clients.

Testimonials Amisha S 150x150
We don’t even know where to start on everything that Mark has done for us in our recent home search. We are first time home buyers and were naturally a bit nervous about the whole process. We met Mark at an open house and instantly liked his honest and data-driven approach. He spent a lot of time understanding our requirements and came well prepared with market research on the neighborhoods we were interested in. Not only that, he also recommended us specific streets in those neighborhoods that once again reflected his knowledge of the area. We saw a few homes

“Just SOLD by Viv!”

Testimonials Chary P 150x150
“JUST SOLD by Viv!” This is to rave (not just put in a good word) about Viv as our realtor. She was there for us 110%. She gave her best and gave her all to achieve her A+ on this project: the sale of our condo in San Carlos. She was enthusiastic! She wanted to do this. And she did it with flying colors and excellently I might add. Let us give you an example. It is an hour before Open House. The pool was clean but not immaculate. There were some leaves in it. Viv went out to the pool, found the pool net

It was such a pleasure to work with Mark and Viv!

It was such a pleasure to work with Mark and Viv of Vabrato Real Estate!  I was pretty confident when I chose them to sell my home because I saw what they were able to do as agents for a home around the corner from mine.  They completely exceeded my expectations!  My home needed renovations before the sale and they handled everything.  Mark has a contractor’s license in addition to his real estate license.  He made suggestions on updates and provided quotes by item.  I was able to tell him what I wanted done and what I didn’t.  He listened

I highly recommend Mark for anyone looking for a top-notch real estate agent

5 stars isn't high enough
5 stars isn’t high enough!  Mark Martinho was the perfect real estate agent.  My brother and I were selling a family home in San Carlos that was held in a trust and had been the family for over 50 years.  We both live out of town.  Mark orchestrated the entire re-model and staging.  It was a huge job.  He coordinated all of the workers, painters, floor people, haulers, and stagers.  Mark has connections with people that do all of these things.  We never had to lift a finger! Mark also has the knack for knowing exactly what needs to be

Viv is terrific!

User Icon Man 150x150

Viv is terrific!  We are first time home buyers.  Viv was great to work with–she listened carefully to us, helped us figure out what was realistic in this crazy market, and helped us make an offer in lightening time (she stayed up late into the night answering all of our questions and remaining calm and patient).  If you are looking in the San Carlos area and surrounding areas  I highly recommend Viv!
