Interest-Only Loans in San Francisco
What's the monthly payment on an interest-only loan in San Francisco?

Interest Only Loans are offered by a smaller pool of lenders than conventional 30-year fixed mortgages. Most require jumbo loan minimums and stricter documentation.
Brokers can access portfolio lenders and specialty programs that retail banks don't offer. Underwriting timelines run 45-60 days due to the added complexity of interest-only structures.
04
Interest Only Loans make sense for San Francisco buyers who expect income growth or plan to sell within 5-7 years. They're a poor fit for retirees or anyone on a fixed income.
At the $1,249,125 conforming ceiling, an interest-only payment runs roughly half the cost of a full 30-year amortization. That breathing room matters when you're stretching to afford the city.
05
A 30-year fixed mortgage offers payment certainty from day one. Interest Only Loans trade that certainty for lower initial payments—but the payment shock at the end of the interest-only period can be severe.
Conventional loans at 20% down carry no mortgage insurance. Interest Only Loans often cost 0.25–0.5% more in rate to offset lender risk, eating into the payment savings.
06

San Francisco's school board announced enrollment changes and closures without advance notice. Families should verify school assignments early if children are part of your purchase decision.
07
San Francisco's high-income professionals drive demand for interest-only loans above the conforming limit. Lenders see these as specialty products for a narrow buyer segment.
Portfolio lenders and jumbo specialists dominate the IO market. Retail banks rarely offer them due to regulatory scrutiny and portfolio constraints.

Yes — 20% down is the standard minimum. Some lenders accept 15% with strong reserves and income, but 20% is the safe floor. Less than 20% down typically disqualifies you.

Yes, but with stricter terms. Lenders require 25% down, higher FICO (720+), and proof of rental income or reserves. Investment IO loans cost 0.5-1% more in rate than owner-occupied.
