Interest Only loans are a niche product in California. Retail banks rarely offer them; portfolio lenders and private mortgage companies dominate this space.
Underwriting is tighter than conventional. Lenders scrutinize income documentation, reserve depth, and credit history more closely. Closing timelines run 45–60 days because the loan file needs extra review.
Interest Only loans make sense in Colma for one specific buyer: someone with strong income growth expectations and a clear exit strategy.
They don't work for buyers who plan to stay 30 years or who have uncertain income. The payment shock when the loan converts—often doubling or more—can be brutal if your income hasn't grown.
A 30-year fixed mortgage carries a higher rate but zero payment shock. Your payment stays the same for 30 years. Interest Only starts lower but jumps significantly after year 5 or 10, when principal kicks in.
Jumbo loans (above $1,249,125) follow similar structures but require 25% down and stricter reserves. If your Colma purchase stays under the conforming limit, Interest Only is more accessible than a jumbo Interest Only product.
Downtown San Mateo is attracting new dining and office investment. Reposado opened a second location in February 2026, and the city council is weighing a regional transit tax to fund Caltrain and BART expansion.
Colma's proximity to these employment and lifestyle hubs makes it a logical choice for buyers who work in tech or finance. The lower initial Interest Only payment gives you breathing room while you establish yourself in the county.
The loan converts to principal-and-interest amortization. Your payment typically doubles or more because you now pay back the full balance in the remaining term. Plan to refinance or sell before conversion to avoid payment shock.
No. Your payment covers interest only, so the loan balance stays flat. You build equity through home appreciation and by refinancing into an amortizing loan before conversion.
Most lenders require 700+ FICO. Some portfolio lenders go as low as 680, but you'll pay a rate premium and need stronger reserves. The higher your score, the better your rate and terms.
Rarely. Most lenders require 20% down minimum. Some portfolio lenders accept 15% down, but you'll face higher rates and stricter income/reserve requirements. 20% is the practical floor.
Typically 5 to 10 years. Most loans default to 5 or 7 years, though some lenders offer 10-year interest-only periods. Confirm the exact term with your lender before closing.
