Not every lender offers jumbo ARMs. Big retail banks have them, but their pricing is rarely competitive. Wholesale lenders we access often beat retail by 0.25–0.5 points on the margin.
Portfolio lenders are worth knowing about here. They hold loans on their own books, so they set their own ARM terms — sometimes with better caps and longer fixed periods.
The ARM structure that fits Monte Sereno buyers best is usually a 7/1 or 10/1. You get a fixed rate for seven or ten years, then it adjusts annually. Most buyers refinance or sell before adjustment hits.
Watch the caps. A 2/2/5 cap structure means: 2% max first adjustment, 2% max each year after, 5% max lifetime. That's your worst-case scenario. Know it before you sign.
A 30-year fixed gives you certainty. An ARM gives you a lower rate upfront. On a $2M loan, a 1-point rate difference saves roughly $1,650 per month in the early years.
