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.

In 2014,

Emily P recommends Joraine Costales

Joraine and Marc are the best team! As a first time homebuyer, I found them to be very honest, professional, and truly caring and putting their clients needs first. The whole home buying experience can be stressful but it went smoothly. They truly went above and beyond our expectations. I also appreciative how responsive they were via text, email, phone calls etc. I highly recommend Joraine and Marc for all your real estate needs.

Candice Castillo recommends Pia De Castro

Pia De Castro is amazing! She has your best interests in mind and always has your back. She has high integrity and expectations of her peers to ensure the clients are always taken care of. She goes above and beyond to show her appreciation for trusting her to manage one of the biggest decisions you will make. Pia made herself available to me even on vacation with her family. She's super polite and always professional. She makes great recommendations for inspectors as well as keeping close ties with other Realtor professionals in the industry. I would strongly recommend Pia to anyone looking to make a first-time home purchase. Thank you, Pia for making my first home purchase a special and memorable experience. You are absolutely wonderful!! I look forward to enjoying my beautiful investment, and I have YOU to THANK! I'll see you soon!

Thomas Fan recommends Margaret Lin

Financial Center Lending Officer

I had the pleasure of working with Margaret Lin last month (July 2019) on a purchase transaction in Hayward, CA. She is a knowledgeable professional and has a vast understanding of the real estate market throughout the entire Bay Area and beyond. She also is highly successful in getting her buyer's into contract with her superb negotiation skills. What truly sets her apart from other agents though is her genuine care and need to take care of her clients. Throughout the entire transaction, she catered to her clients needs and made sure that every action and detail was to truly benefit them (whether they knew it or not). I would highly recommend to choose Margaret for either buying or selling your home as her customer service is unmatched and you know that she will have your best interests top of mind!

Audrey Hutton recommends Pia De Castro

Branch Manager, Loan Officer

From the very first phone call I received from Pia, I could tell she was going to be amazing. We had a client that was a first time home buyer, with limited funds, in a challenging price range and qualification, and that didn't intimidate Pia at all. She treated our client with the same urgency and gave amazing customer service as she would have anyone else. She has amazing energy, negotiating skills, and tenacity when not giving up in finding the perfect home for the clients. Our client was 110% thrilled with her service and on the loan side, it is so refreshing to work with a professional such as Pia. You can tell she really cares and goes above and beyond!

Sales associate

Pia was a pleasure to work with. She was on top of everything and gave me updates on every thing to make sure we were all on the same page. She was able to represent her buyers in their best interest without having to make this a buyers vs sellers kind of transaction.

She is reliable, responsive and fast and I would highly recommend working with her again!

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.

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.

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.

Thank you Pia for finding my dream home. I highly recommend her & Pia De Castro Team to all my friends & family.

Elga Alderete recommends Luzbelinda "luchie" Grissom


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

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


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


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.
