A California jumbo loan is any loan above your county's conforming limit — $1,249,125 in high-cost counties (LA, Orange, SF, Santa Clara), $832,750 baseline. To qualify, expect a 700+ credit score (720+ on larger loans), 10–20% down (20% standard), a DTI around 43%, and 6–12 months of cash reserves. Loans above ~$1M often need two appraisals. Who qualifies and how to document income is on Eligibility.

The jumbo threshold — where jumbo begins
A loan becomes "jumbo" the moment it exceeds your county's conforming loan limit. In California that line is high, because home prices are:
| County type | 2026 conforming limit (1-unit) | Above it = |
|---|---|---|
| High-cost (LA, Orange, SF, Santa Clara, San Mateo, Alameda, Marin, Riverside) | $1,249,125 | Jumbo |
| San Diego | $1,104,000 | Jumbo |
| Baseline (e.g. Sacramento) | $832,750 | Jumbo |
Between the baseline and high-cost limits, a loan is a "high-balance" conforming loan, not jumbo — often with easier terms. So in an expensive county, you can borrow up to $1,249,125 and still be conforming. Always check your specific county before assuming you need jumbo. See Eligibility for the high-balance distinction.
Credit score
| Loan profile | Typical credit minimum |
|---|---|
| Standard jumbo | 700 (some lenders 680 with compensating factors) |
| Larger jumbo (~$2M+) | 720+ |
| Super-jumbo ($3M+) | 740+ |
| Best pricing | 740–760+ |
Jumbo credit standards are higher than conforming because the lender keeps the loan rather than selling it to Fannie Mae or Freddie Mac — so they carry the full risk. A stronger score doesn't just approve you; on a large balance, the rate difference between a 700 and a 760 score compounds substantially over 30 years.
Down payment & LTV
The standard is 20% down, but the range is wider than most expect:
- 20% down — the standard, and it avoids mortgage insurance entirely.
- 10–15% down — available on strong profiles, often up to ~$1.5–2M.
- 5% down — some programs allow it up to ~$2M with a 680+ score and reserves.
- 25%+ down — earns the best pricing and larger loan caps.
Unlike conforming loans, many jumbo programs offer no-PMI options even below 20%, via a single loan or a piggyback structure. We'll match your down payment to the best-priced program.
DTI & cash reserves
| Requirement | The standard |
|---|---|
| Debt-to-income | ~43% or lower (flexible with strong reserves) |
| Cash reserves | 6–12 months of payments, after down & closing |
| Reserves can include | Retirement & investment accounts |
| Income docs | Full documentation (or non-QM for self-employed) |
Reserves are the requirement borrowers underestimate most. On a jumbo loan, lenders want to see 6 to 12 months of mortgage payments still in the bank after your down payment and closing costs — proof you can weather a rough patch. The good news: retirement and investment accounts usually count. Self-employed? You may not need tax returns — see the documentation options.
The two-appraisal rule
On loans above roughly $1 million, many lenders require two independent appraisals. Because a jumbo loan is large and held by the lender (not sold to Fannie or Freddie), they want extra assurance the home is truly worth the price — high-end homes have fewer comparable sales, so valuation is harder. It adds some cost and time, but it's routine at this loan size.
