Riverside · Inland Empire · Since 1988
Real estate, home loans, and property management. One call.
I've been in real estate since 1988. I founded National Realty Group in 1991 and have owned National One Mortgage since 1994. Whether you're buying, selling, financing, or renting out a property, you can call me directly, and I'll put the right part of the operation to work for you.

The One Stop Solution
One team from the first showing to the first rent check.
Most people piece a move together from an agent, a lender, an escrow company, and later a property manager who don't always talk to each other. My companies cover each step, so there is one point of accountability, and it's me.

About
Broker, lender, and the guy who answers the phone
Sales, lending, investing, and flipping give me a complete view of how deals succeed and how they fall apart. I hold an MBA, and I mentor small business owners around one question: are you an owner or an employee?
