Intero Real Estate Union City

Before Silicon Valley was duly named, its history as the hotbed of innovation was well noted. Our catchy moniker reflects the giants of technology who line the corridors of Cupertino, Mountain View, Menlo Park, Palo Alto, and Sunnyvale; the wave of progressive firms that have shaped electronics, e-commerce and social interaction all call this place home.

In its truest form, innovation knows no boundaries. It isn’t contained by market or economic trends. Silicon Valley is where everyone gathers at the water cooler of progress, questioning why things can’t be better.

It’s from that fountain that the founders of Intero drank.

It was 2002. Silicon Valley was mired in the dot-com bust affecting all corners of the technology sector. As a result the local real estate market grinded to a halt. In true Silicon Valley spirit, that was the exact, perfect moment to launch a startup real estate brokerage.

Intero’s desire wasn’t to be like all other brokerages. Not only were we committed to providing our residents and neighbors a service that heralded the very nature of where we live, we owed it to our new neighbors, recruited from all over the world to come and work for many of the most creative, progressive companies on the planet.

Powered by an entirely new technology platform, backed by a solid investment, led by a team of real estate veterans who were all born, raised, and weaned right here in the Silicon Valley, Intero Real Estate Services was born.

While the dot-com bust remedied, in 2007, the real estate bubble burst and its subsequent effects on the market and economy were well documented. For us, this signaled a moment in time to do what we do best - invest in our company and innovate further.

Over the past seven years, against the pressures of a challenging market, we continued to advance our training programs, update all of our technology, grow our brand into other markets, and build a luxury sub brand.

We did all this because this is who we are.

Cynthia Raymundo recommends Margaret Lin

We bought our dream home from Margaret 11 years ago. When it was time for us to sell our home, we had no one else in mind but her to be our realtor.
Margaret is hard working, kind- hearted, honest and trustworthy. She has been such a blessing to us.

Mandar Ashtekar recommends Jennifer Angel

Awesome Jennifer

No doubt we had a wonderful experience while buying our home. Jennifer was very patient about the barage of questions we kept on asking her. Even though our budget was less and we kept rejecting homes like we have all the budget in the world, she was very calm and answered/assisted us with the same enthusiasm. Great agent!!!

Jennifer was incredibly helpful through-out the home buying process. She's highly knowledgeable, informative and provided insight when needed. She made the first time home buyer experience easier than what I had expected. I highly recommend her as an agent and would most likely use her services again given the chance.

We were very happy with Pia on how she drove the whole buying process smoothly with no single hiccup. As first time buyers in US we were having several questions, Pia was always available and patient to address our queries. Feel that we were fortunate to meet such a friendly, professional and approachable Pia in right time. We personally look forward to maintain the bonding and work with her again in future.

Very Happy Client of Pia De Castro

Pia is very knowledgeable & knew the areas pretty well. She advised me ahead of time of good areas of investment to buy my house. She always returned my calls on time.

My wife and I had a great experience working with Luchie. We couldn’t believe how responsive she was to all of our requests and questions, and she knew far more than we ever hoped to about the process of selling our Mobile home.

We couldn’t recommend her enough for anyone looking for some peace of mind when selling or buying a home!

David Vetterlein recommends Pia De Castro,Top 10% Agent Nationwide

Consultant Biotechnology

Pia is very professional and helped us wade through the issues and challenges of selling a nicely maintained 50 year old house in the California housing market. This was my parent house and I live in Washington State. She provided excellent advice and the resources we needed to prepare the house for sale and after the sale. She is an excellent communicator and worked quickly and effectively to get the house sold—within weeks. The house was sold at way over the asking price and both the buyers and sellers were happy with the outcome. I would recommend her to anyone who needs help with selling a house.

Karen Dinucci recommends Pia De Castro,Top 10% Agent Nationwide


Pia has helped my family with the sale of two homes. After the sale of our personal home, she was the first person I called when it came time to sell my parents' home. My parents are both in their 90s and she did a great job accommodating their needs. In addition to being very personable, Pia is organized, knowledgeable, and communicative throughout the entire selling process. She sold both homes for over listing price from start to close within 30 days! I highly recommend her.

Francisco Family recommends Pia De Castro,Top 10% Agent Nationwide


Being a clueless first time homebuyer that we were, we had tons of questions regarding the process and how we were going to compete competitively especially in the hot market that we have here. Pia guided us all the way through, even after multiple offers and frustrating losses, she never gave up and kept our sprits high.
She promptly answered all our questions and was very professional throughout the whole deal.

We finally found a home meant for us and just can't thank her enough.

Michelle Lin recommends Cara Milgate

Cara is wholeheartedly interested in helping me flourish as a successful agent. She continually strives to make each agent in the office a better leader in all aspects, whether it’s finding the newest software to bring in better leads or various resources for us to be on the latest trend. Cara is selfless and continually devotes her time to make sure we are all set up for success. She is honest and gives genuine feedback every time I have reached out for help and advice. She also offered to arrange a meeting with some agents from the office so that I could get more insight into their structure, goals, and daily doings.

Whenever I have questions or concerns, Cara responds right away and even follows up later in the week or month to make sure my issues have been accommodated. Her patience and willingness to help have made me motivated to do the best job I can, and I can’t thank her enough for her constant diligence and hard work she displays each and every day. Thank you, Cara.

Melody R recommends Joraine Costales

I wasn't gonna yelp until after we got into our new house but really I just couldn't wait to rave about my cousin and her team. The Flores/Costales team was amazing. Let me go back just a little and say that I've know Joraine since she was 15 and I've had the pleasure of watching her grow from an immature little teen working at the children's place into the real estate mogul you have before now. Even when we weren't ready to sell or buy just quite yet, Joraine and her team answered our what if's and was very supportive. When we finally decided to go for it, her presentation blew me and my husband away including her backstory of how she got so good at it. Wowwed and awed by it all, we went for it. It took a little while especially after my father in law passed away, she was there every step of the way with Marc who came by just to fix our crooked sign outside, Jomar who watched the kids including our son, JT while Joraine and Marc showed us a cpl of houses, Mason and Gianna who were cute as hell while the open houses were going on, and assistant, Amanda who was here when the Flores/Costales family couldn't and sent us every document we needed to sign making sure we crossed our t's and dotted our i's. If you are looking for a go getter and a realtor, team Flores/Costales is it. Trust me. You won't go wrong with them.
