Not every lender prices ARMs the same way. Some wholesale lenders we work with offer sharp 5/1 and 7/1 ARM pricing not available at retail banks.
Portfolio lenders are especially useful for high-balance Mountain View purchases. They hold the loan themselves, so they can flex on guidelines.
A 7/1 ARM is the sweet spot for most Mountain View buyers we work with. Seven years of fixed payments covers most typical holding periods.
Know your caps before you sign. ARMs have periodic caps and lifetime caps — usually 2/2/5 — meaning rate can't jump more than 5 points total.
Fixed rates buy certainty. ARMs buy lower payments now in exchange for future rate risk.
On a $1.5M Mountain View purchase, a 1-point rate difference on a 7/1 ARM versus a 30-year fixed can mean $900+ saved monthly for seven years.
Mountain View's tech-heavy buyer pool moves fast. Short holding periods due to job changes or equity events make ARMs a natural fit.
Santa Clara County's high price points mean even conforming ARMs often sit near the $832,750 limit. Many buyers step into jumbo ARM territory immediately.
Most buyers here use 7/1 or 10/1 ARMs. The first number is the fixed-rate years before adjustments begin.
The rate ties to an index like SOFR plus a margin. Caps limit how much it can move per adjustment and over the loan's life.
Yes. Many Mountain View buyers refinance or sell before the first adjustment. That's often the whole strategy.
They're common here. Jumbo ARMs often price sharper than jumbo fixed loans, which matters on $1.5M-plus purchases.
Most lenders want at least 620. For jumbo ARMs above $1M, expect lenders to prefer 720 or higher.
There is rate risk after the fixed period ends. Buyers who plan to sell or refinance within the fixed window carry much less risk.
