Jumbo loans aren't sold to Fannie Mae or Freddie Mac. Each lender sets its own rules — rates, overlays, and reserve requirements vary significantly.
Portfolio lenders and large private banks dominate the jumbo space. Shopping just one lender here is a costly mistake.
RSU income is the tricky part in Cupertino. Some lenders won't count it at all. Others average two years of vesting history. Know which lender accepts your income structure before you apply.
Appraisals on jumbo loans get extra scrutiny. In a fast market, a low appraisal can kill a deal. Get your broker involved early so you're pricing the right loan amount from day one.
A conforming loan caps at $1,249,125 in Santa Clara County. Above that, jumbo is your only path — unless you're putting down enough to stay under the limit.
ARM products (adjustable-rate mortgages) are common on jumbo loans. A 7/1 or 10/1 ARM can price meaningfully lower than a 30-year fixed. That matters on a $2M loan.
Cupertino's buyer pool skews heavily toward tech workers with equity-heavy compensation. RSUs, ISOs, and performance bonuses are common — and complicated for lenders to underwrite.
Competition here is real. Sellers expect clean offers. A rock-solid jumbo pre-approval — not just a pre-qual letter — is what gets your offer taken seriously.
Any loan above $1,249,125 is jumbo in Santa Clara County. Most Cupertino purchases land well above that limit.
Yes, but lender rules differ. Most require a two-year RSU vesting history. Some won't count RSUs at all.
Most jumbo lenders want 720 or above. Scores under 700 will disqualify you at most institutions.
Expect a minimum of 10-20% down. Larger down payments unlock better rates and easier underwriting.
It depends on your timeline. A 7/1 or 10/1 ARM prices lower and suits buyers who may sell or refi within a decade.
Jumbo pricing varies more than any other loan type. A broker shops multiple lenders at once — a direct bank shows you one rate.
