Buy. Sell. Invest.
Without guessing.
Buying, selling and investment representation across Chino Hills, Riverside, San Bernardino and the greater Inland Empire — priced from closed sales on your street, never a ZIP-code average.
What clients
actually say
“My house wouldn't have been sold without him. He gave me million dollar listing service on a small home. My house was only on the market 21 days when other homes in my neighborhood have been on the market for over a year. He quickly responded to every question or concern I had and walked through the whole process. It was a great experience and I would definitely recommend and use him again.”
“We were only looking to move up in size and willing to be flexible in what we chose. Sebastian actually found us a house that we love! He was extremely responsive and very friendly and professional. He helped up sell our current residence and buy our new place at the same time.”
“Sebastian did an amazing job helping me purchase my home. I stayed in the exact area I wanted and he worked with me to keep the monthly payment in budget. He even introduced me to my new favorite breakfast spot. Great guy and even better agent.”
What do you
need done?
Every engagement starts the same way — a straight conversation about what you're actually trying to accomplish, before anyone talks about listings.
The Track Record
Not the biggest number on any agent's website — it is the number of people who have actually worked with Sebastian, and every one of them left five stars. A brokerage's company-wide volume would look more impressive here. It would also not be his.

Sebastian Street
REALTOR® · CA DRE #02208742“Most people don't lose money on a house because they picked the wrong home. They lose it because nobody ran the numbers honestly before they signed.”
Sebastian works out of Chino and covers the three-county seam where Chino Hills, Eastvale and Diamond Bar meet — a stretch where the property tax rate, the Mello-Roos exposure and the school district can all change inside of a five-minute drive. Most of what he does for clients is making sure those differences show up in the math before an offer gets written, not after.
Whether you're selling a Chino Hills home, buying your first place in Ontario, or underwriting a rental in Fontana — the first conversation is free and there's no pressure attached to it.
Areas Serviced
The Inland Empire is not one market. Chino Hills, Eastvale and Diamond Bar sit minutes apart in three different counties, with different tax rates, different school districts and different Mello-Roos exposure. Knowing the difference is the job.
Answers,
straight
The questions people actually type before they call an agent — answered without the hedging.

Submit your property address through the valuation request form on this site, or call (626) 632-2559. Sebastian prepares a written valuation from closed comparable sales matched to your specific tract rather than a ZIP-code average, and delivers it within 24 hours. There is no cost and no obligation to list.
Yes, and first-time buyers are a significant share of the practice. Sebastian is an approved originating partner for CalHFA Dream For All, California's shared-appreciation down payment assistance program, and also guides buyers through conventional 3%-down, FHA 3.5%-down and VA zero-down financing. Eligibility is confirmed before touring so buyers shop with an accurate budget.
Since the 2024 NAR settlement changes, both listing-side and buyer-side compensation are negotiated and disclosed in writing rather than assumed from a standard rate. Sellers agree to a listing fee and separately decide what, if anything, to offer a buyer's broker. Buyers sign a written representation agreement specifying their agent's compensation before touring homes. Sebastian provides written net-proceeds and cost estimates before any agreement is signed.
