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.

Wendy recommends Joraine Costales

The Costales team helped my husband and I but our first home during the covid Era. We started working with them pre Covid and it nearly took 2 years before we found our home at the price we were comfortable with. They've been so patient with us. We had a long list of criteria and the right one came along. There was never any pressure or did we ever feel like we were neglected during the covid times. They always texted our cakes to check in... for that we felt well taken care of. We're coming close to a year from the time our offer got accepted and they are still checking in to see if we need anything at the home.
If you're looking for a realtor, the Costales team is THE ONE.

Abi U. recommends Joraine Costales

The Costales Team are exceptional realtors and even more exceptional people. Working with them you get:

1) Advisors with a wealth of knowledge on the market and the community. They'll show you possibilities and ask the questions you didn't know you needed to ask

2) Quality Service. Throughout the process of buying and selling, the Costales Team regularly communicates, offers feedback and options, and asks how you are feeling. They present themselves professionally and genuinely which makes it easy for everyone involved in the transaction to work with them and want to work with you!

3) A lot of hustle & heart. As their logo states, "hustle & heart sets us apart". It really does. Buying a home or selling one is an extremely personal process. The Costales Team never backs down from a challenge (I sold my first home and bought a new home at the start of market shift..) and they really are up all night doing everything in their power to give you what you want. I read through a forwarded thread during our transaction and literally cried when I saw all the back and forth between the Costales Team and our builder. I knew they were really doing their best to make sure my family (kids, pets and all) were going to be taken care of. Additionally, wherever they serve they take care of everyone. In selling our house, they fed our neighborhood with free hot dogs and sodas. They are generous in donating to the community and continue to check in on us after closing.

I've purchased 2 homes and sold one home with the Costales Team and while each situation presented different challenges, the Costales Team has delivered a consistent positive experience each time. Finding a home is way more than a business deal, it's a big life event that should be celebrated and not stressed over. We are so grateful to Joraine and Marc for helping our family into this new adventure, we couldn't have done this with anyone else!

Joraine and Marc Costales made our experience as first home buyers very easy.

Scott Nguyen recommends Anthony Sabeh


First time home buying can be a stressful and nervous process however with Anthony Sabeh as our realtor, this made the process super easy and exciting for both my wife and I. First off, not every realtor is the same. The large amount of knowledge Anthony has with home building and local city codes as well as home styles made every home Anthony showcased to be very desirable and he even made every tour seem personal with giving factual historical information on the home as well as stepping and showing every square inch of the stone. ImAnthony has a direct way of handling tasks and when reviewing the homes disclosure, Anthony went over each section regarding the home condition making us feel extra confident that the home was right for us. With Anthony by our side, it was was like a walk in the park mainly because Anthony actually cared for us to be in a home. At the end of the day, that was what my Wife and I wanted. Anthony worked with our busy schedules and found time to search for homes with us and meet with sellers. My wife and I strongly recommend anyone that needs an agent to contact Anthony Sabeh if you are buying a home or even selling your home. Anthony will make sure you get the results you want! Thank You Anthony!

Margaret is a great agent, and I had a great experience with her.

Janine Avila recommends Pia De Castro

Pia was referred to me by my two sisters whom she also helped purchase homes for. We scheduled a Zoom meeting in June and I honestly was not planning to buy a home right then and there, I just wanted to see what I can afford. From the day of the Zoom meeting everything happened so quickly, we had the meeting, got our pre-approved loan, looked at homes and now we are home owners. In a span of 1 month, we went from renting a home to becoming first time home owners. Pia and her team made the process so seamless and easy. We got a great deal on a beautiful home. Even though we had the lowest down payment and 5 other offers, Pia did her magic and got us in. I 100% recommend her! She’s great, straight to the point and well known. It only takes one meeting to gets things started. Thank you Ateh Pia! We appreciate you and your team so much!

Purchase of new Single Family Home

We called Margaret and told her that we wanted to purchase a new home. We knew instinctively to call her, because she had helped us buy our first condo three years ago, helping us get a great deal and now we were ready for a house. In today's competitive market you can believe that we had to see a lot of homes. When we finally saw our dream house, we knew we had to put in offer in. Margaret was quick to provide us as much information as she could generate to give us the best information on what to put as an offer. With Margaret's great communication with the seller and making sure that we had all of our paperwork in order to get our accepted. Now we live in our forever home.

Jamie Aldine recommends Terrie MacDonald

First of all, I’ve always been told “go by word of mouth.” We found Terrie, by word of mouth. The absolute best recommendation ever given. So here is my, word of mouth.
Terrie, helped my mom through the sale of my childhood home. That being said, she lived in this house for over 50 years with a lifetime of acquired belongings and memories to pack up. When you’re 72 years old, it’s not easy to just stick a for sale sign up in your yard. All the emotions come with that. That is where Terrie stepped in and helped my mom, answered every question, even if the same question was asked 20 times. Terrie, never got frustrated or never lost her cool. The line of communication was on point.
Terrie was upfront with us, explained every step of the process and each time we would move forward to the next step, she would explain, then make sure we had no questions.
Terrie even helped us find places to donate things we didn’t need.
When you find someone that you’re comfortable with and makes you feel like there is no such thing as a stupid question, you stop and write a great review.
Thank you Terrie’s for all you have done for our family, we will forever be grateful

Waldo Saturnino recommends Pia De Castro

We are renting an apartment for more than twelve years . Just like many people we also dreaming to have a place of our own.. a house that we can called ours.At first we are reluctant to go through on purchasing a home since it is inflation and the houses price are high. We did not allow the situation kills our dream. Pia and Mohammad help us to make the impossible be possible for us. They assist us from the beginning up to the closing . I remember the one thing that Mohammad requested to me and my wife, it is to trust them and so we did!
After five weeks of smooth transaction with them we are now a homeowner. To those who are looking for an agent and lender I highly recommend their team.
