Interest-only loans make sense in Sunnyvale for high-income professionals expecting significant raises in the next 5-10 years. The payment relief during that window is real, and refinancing to principal-and-interest later is straightforward.
Above $1,000,000, conventional financing becomes expensive due to jumbo pricing. Interest-only can cost less per month than jumbo conventional, making it the smarter choice for qualified buyers.
Conventional loans above the conforming limit require jumbo pricing—typically 0.25% to 0.5% higher rate. Interest-only avoids that rate penalty and keeps your monthly payment lower during the interest-only period.
The tradeoff is simple: jumbo conventional builds equity from day one but costs more monthly. Interest-only defers principal but requires you to refinance when the term ends.
