Interest Only Loans are offered by select portfolio lenders and some jumbo specialists in California. Retail banks rarely offer them; most come through brokers with access to private or portfolio lending channels.
Underwriting is stricter than conventional loans because the lender carries more risk during the interest-only period. Expect longer timelines and more detailed financial review than a standard 30-year fixed.
Interest Only Loans work best for San Bruno buyers with high income, significant assets, and a clear plan to refinance or pay down principal later. They don't fit buyers who need predictable payments or plan to stay in the home long-term without refinancing.
If you're buying above the conforming limit of $1,249,125 and want payment flexibility in the first years, this structure can be strategic. Below that threshold, a conventional loan with a lower rate often makes more sense.
A conventional 30-year fixed offers predictable payments and a clear amortization schedule. Interest Only trades that certainty for lower initial payments, but you'll face a payment jump when the interest-only period ends.
Jumbo loans at this price point typically carry higher rates than conventional but offer more flexibility on terms. Interest Only is a specialized variant that requires stronger credit and reserves than a standard jumbo.

Yes — most lenders require at least 20% down for interest-only loans. Some portfolio lenders may go lower with strong credit and reserves, but 20% is the standard minimum. This reduces the lender's risk during the interest-only period.
Yes. Most borrowers refinance before the interest-only period ends to lock in a new rate or switch to a standard amortization. Refinancing is typically part of the strategy when taking an interest-only loan.
Buyers with high income, significant assets, and a clear refinancing plan benefit most. They work well for investors or buyers expecting income growth. If you need predictable payments, a conventional loan is safer.
Most lenders require a minimum FICO score of 700. Some portfolio lenders may consider 680–700 with strong compensating factors like high income or large reserves. The stronger your credit, the better your rate.
