Jumbo Loan Requirements: What It Takes to Borrow Over $806,500
A jumbo loan is any mortgage that exceeds the conforming loan limit set by the Federal Housing Finance Agency — $806,500 for a single-family home in most US counties in 2025. In high-cost counties (parts of California, New York, Hawaii, and others), the limit is higher, up to $1,209,750. Any loan above those limits is a jumbo loan.
Because jumbo loans can’t be sold to Fannie Mae or Freddie Mac, lenders hold them on their own books — which means stricter underwriting standards and more variation in requirements between lenders.
Jumbo Loan Requirements at a Glance
| Requirement | Typical Standard |
|---|---|
| Minimum credit score | 700–720 |
| Down payment | 10–20% typical; 0–10% for some programs |
| Maximum DTI | 43% |
| Cash reserves | 6–18 months PITI |
| Income documentation | 2 years, fully documented |
| Loan amount | Above $806,500 (most counties) |
| PMI | Varies — some lenders require it, some don’t |
| Property appraisals | Often two appraisals required |
Credit Score
Most jumbo lenders require 700–720 as a minimum, with the best rates reserved for borrowers at 740–760+. Some portfolio lenders go as low as 680 for exceptional borrowers with large down payments and strong reserves, but this is the exception.
At the credit score thresholds where conventional loans become most competitive (720+), jumbo lenders are just getting started in terms of favorable pricing. The rate spread between a 700 and a 760 borrower on a jumbo loan is often larger than on a conforming loan — lenders price risk more aggressively at high loan amounts.
Down Payment
Typical minimum: 10–20%. Unlike conventional loans, there’s no standardized floor. Most jumbo lenders want to see at least 20% down to avoid both PMI and the additional risk of a high LTV at a large loan size.
Below 20% down jumbo programs exist — some banks and credit unions offer jumbo loans with 10% or even 5% down for borrowers with exceptional credit and high income. These programs typically carry higher rates and sometimes require PMI.
Loan-to-value tiers:
- 80% LTV (20% down): Best rate tier, no PMI at most lenders
- 85% LTV (15% down): Available, with rate premium and sometimes PMI
- 90% LTV (10% down): Available at select lenders, meaningful rate and cost premium
Cash Reserves: The Most Distinctive Requirement
This is where jumbo underwriting most visibly differs from conventional. Lenders typically require 6–18 months of PITI in verified liquid reserves after closing.
On a $1.5 million loan with a $7,000/month payment, 12 months of reserves means $84,000 in liquid assets beyond your down payment and closing costs. That’s a significant bar.
What counts as reserves:
- Checking and savings accounts
- Investment accounts (stocks, bonds, mutual funds) — often at 60–70% of market value to account for liquidation risk
- Retirement accounts — at 60–70%, accounting for taxes and penalties
What doesn’t count: Home equity in other properties, business accounts, borrowed funds.
The reserves requirement is why jumbo loans disproportionately favor borrowers with established wealth — not just high income, but actual liquid assets.
Debt-to-Income Ratio
Maximum: 43%. Jumbo lenders are more conservative on DTI than conventional (which allows up to 50%). Many jumbo lenders have a hard 43% cap with limited exceptions.
At high loan amounts, the housing payment itself consumes a large portion of income. A $1.5 million loan at 7.25% runs approximately $10,238/month P&I. To keep that within 43% DTI, you need gross income of roughly $23,800/month ($285,600/year) before any other debts.
Income Documentation
Jumbo loans require fully documented income — there are no bank statement or asset depletion shortcuts at most traditional jumbo lenders. Some portfolio lenders offer non-QM jumbo products with alternative documentation, but these carry rate premiums.
For W-2 employees:
- 2 years of W-2s
- 30 days of pay stubs
- 2 years of federal tax returns
For self-employed borrowers:
- 2 years of personal and business tax returns
- Year-to-date P&L statement
- 2–3 months of business bank statements
- CPA-prepared documents preferred
Self-employment income is particularly scrutinized in jumbo underwriting. If your business shows declining revenue or significant deductions, expect detailed questions.
Appraisal Requirements
Many jumbo lenders require two independent appraisals — especially on larger loan amounts or unique properties. This is a risk management measure: at $1.5 million+, the lender needs confidence in the collateral value.
Two appraisals add cost ($500–$1,000 each) and time (often 2–4 weeks). Budget for this in both dollars and timeline.
Interest Rates on Jumbo Loans
Historically, jumbo loans carried higher rates than conforming loans because of the additional lender risk. In recent years, the spread has narrowed — sometimes jumbo rates are actually lower than conforming rates, because the borrower pool for jumbo loans skews toward higher-income, higher-credit borrowers that lenders compete aggressively to win.
Today, the rate relationship varies:
- Well-qualified borrowers (760+, 20%+ down): Jumbo rates may be at or below conforming
- Borderline borrowers (700–720, 10–15% down): Jumbo carries a meaningful rate premium
Shop multiple lenders — jumbo rate variation between lenders is larger than in the conforming market because there’s no single secondary market setting the standard.
Types of Jumbo Lenders
Large national banks (Chase, Bank of America, Wells Fargo): Typically offer portfolio jumbo products with competitive rates for strong borrowers. Often offer relationship pricing if you hold significant deposits.
Credit unions: Can offer favorable jumbo terms, particularly for members. Worth checking if you’re a member of a large credit union.
Private banks and wealth management divisions: Cater to high-net-worth borrowers. May offer asset-based lending or non-QM structures not available elsewhere.
Mortgage brokers: Access wholesale jumbo products from multiple lenders. Useful for shopping without applying separately to each bank.
Jumbo vs. Conforming: Should You Stay Under the Limit?
If your purchase price puts you just over the conforming limit, it’s worth calculating whether a slightly larger down payment could bring you under the limit — and into a conforming loan.
Example: $850,000 purchase in a standard county (conforming limit: $806,500).
- Jumbo path: $680,000 loan (20% down, $170,000)
- Conforming path: $806,500 loan with $43,500 down (5.12%)
The conforming path requires less cash down, but puts you in a jumbo loan anyway. To get a conforming loan on this purchase:
- Loan must be ≤ $806,500
- Down payment must be at least $43,500 (5.12% of $850,000)
In high-cost counties with limits up to $1,209,750, more properties fall within the conforming range — check your county’s specific limit before assuming jumbo is required.
Frequently Asked Questions
Are jumbo loan rates always higher? Not always. Well-qualified borrowers often find jumbo rates competitive with or below conforming rates. The key variables are your credit score, LTV, and reserves — lenders price these more aggressively at jumbo loan sizes.
Can I get a jumbo loan with 10% down? Yes, but with a rate premium and often PMI. Some lenders offer 10% down jumbo programs; fewer offer 5% down. Expect fewer options and more scrutiny than a 20% down jumbo application.
Do VA and FHA offer jumbo loans? VA loans can exceed conforming limits (VA «jumbo» loans exist) with a required down payment on the amount above the limit. FHA has separate high-cost county limits up to $1,209,750. Both are handled differently from private jumbo products.
How long does a jumbo loan take to close? Typically 45–60 days — longer than conforming loans due to the more extensive underwriting and potential dual appraisal requirement. Build this into your offer timeline.
The Bottom Line
Jumbo loans aren’t dramatically harder to get for borrowers who genuinely qualify — but they require a higher credit score, more cash reserves, and fully documented income than conforming loans. The rate environment for jumbo has improved significantly, and strong borrowers often find competitive pricing.
If you’re buying in a high-cost market, compare your county’s conforming limit against your target purchase price before assuming you need jumbo. The high-cost conforming limits cover a lot of ground.
