Portfolio ARMs in Costa Mesa
What is a Portfolio ARM and how does it differ from a fixed-rate loan?
A Portfolio ARM locks your rate for 3, 5, 7, or 10 years, then adjusts annually. A fixed-rate loan keeps the same rate for 30 years. ARMs start lower but carry adjustment risk after the initial period.
