Los Altos Hills is one of the most expensive zip codes in the country. Homes here routinely push into the $4M–$8M range and beyond.
At those price points, a conventional fully-amortizing payment is massive. Interest-only structures give high-income borrowers real flexibility on monthly cash flow.

Loan Classification
Interest-only loans are Non-QM products. That means they fall outside standard government guidelines — lenders set their own rules.
Expect a minimum credit score around 700–720. Most lenders want 20–30% down and strong reserves. Income documentation requirements vary by lender.
Most retail banks don't offer interest-only at the loan sizes Los Altos Hills requires. Wholesale and portfolio lenders fill that gap.
We work with 200+ wholesale lenders. Several specialize in high-balance interest-only products for exactly this market.
The typical IO buyer in Los Altos Hills isn't cash-strapped. They're managing liquidity — keeping capital deployed in equity or business instead of a mortgage.
IO periods usually run 5–10 years. After that, the loan recasts and payments jump. Plan for that recast before you sign, not after.
A standard jumbo loan fully amortizes from day one. Your payment covers principal and interest every month. That's predictable — but expensive at $4M+.
An ARM also offers a lower initial rate, but you're taking rate risk. An IO loan separates payment flexibility from rate risk. Different tools for different goals.
Los Altos Hills sits in Santa Clara County. Property values here are driven by proximity to Stanford, major tech campuses, and limited housing supply.
Many buyers are tech executives or founders with variable income — RSUs, bonuses, equity events. IO loans pair well with that income profile.
You pay only the interest each month for an initial period. Principal balance doesn't decrease until the IO period ends.
Most IO loans offer 5 or 10 year IO periods. After that, your payment recasts to cover principal and interest.
Yes. Portfolio and wholesale lenders routinely do IO loans well above conforming limits. This is exactly what those lenders are built for.
Not through payments during the IO period. Equity grows only if the property appreciates — which is historically strong in Los Altos Hills.
Yes. As a Non-QM product, lenders apply stricter credit, reserve, and down payment standards than conventional loans.
An ARM shifts rate risk to you after the fixed period. IO gives payment flexibility without necessarily changing your rate structure.
