04
Interest-only loans make sense in Atherton for short-term ownership or expected income growth. They're less attractive for buyers who want to build equity immediately.
The payment savings in early years are real, but principal balloons at the end. Refinancing or a lump-sum payment becomes necessary when amortization begins.
05
A 30-year fixed jumbo carries higher monthly payments from day one. Interest-only defers that burden but requires a solid exit plan.
Adjustable-rate jumbo loans typically start below fixed rates but carry adjustment risk. Interest-only ARMs combine both risks, suitable only for sophisticated borrowers.
