How much equity do I need?

A rate-and-term refinance can work with as little as 3-5% equity. Dropping PMI takes about 20%, and a conventional cash-out requires you to keep 20% (an 80% loan-to-value cap).

Will refinancing hurt my credit?

The hard inquiry causes a small, temporary dip. Rate-shopping multiple lenders within a ~45-day window counts as a single inquiry for scoring.

Refinance a Jumbo Mortgage

Refinancing a Jumbo Mortgage is more doable than many homeowners assume. Below is what lenders actually require here and how to put your strongest file forward.

The short answer

A jumbo refinance applies when your loan exceeds the 2026 conforming baseline of $806,500 (higher in costly counties). Jumbo loans are not backed by Fannie or Freddie, so lenders set their own tougher standards: usually 700-plus credit, larger reserves, and lower LTV caps (often 80% rate-and-term, less for cash-out). Rates can be competitive with conforming but vary more by lender.

What refinance lenders look for

Equity: ~3-5% for a rate-and-term, 20% to drop PMI, and 20% kept for a cash-out (80% LTV cap).
Credit: roughly 620+ for conventional; FHA and VA streamlines do not re-check your score.
Debt-to-income: generally under ~43-50% including the new payment.
Break-even: closing costs divided by monthly savings — refinance only if you will keep the home past it.
