When your loan amount exceeds King County's $1,063,750 conforming limit, you enter jumbo territory. At 20% down, you can finance homes priced up to about $1.33M within conforming limits. Above that, jumbo is your path. While jumbo loans require more documentation and stronger financials, 20% down borrowers typically enjoy the smoothest underwriting and most competitive rates.
20% Down Payment Amounts
| Home Price | 20% Down | Loan Amount |
|---|---|---|
| $1,400,000 | $280,000 | $1,120,000 |
| $1,800,000 | $360,000 | $1,440,000 |
| $2,200,000 | $440,000 | $1,760,000 |
| $2,800,000 | $560,000 | $2,240,000 |
Typical Jumbo Requirements at 20% Down
Credit Score
Most lenders require a minimum 680-700 credit score at 20% down. Borrowers with 740+ scores qualify for the best rates. Some lenders offer jumbo products down to 660 with compensating factors, but options narrow significantly.
Cash Reserves
Expect to show 6-12 months of mortgage payments (including taxes and insurance) in liquid reserves after closing. The exact requirement depends on loan amount:
- Under $1.5M loan: 6 months typical
- $1.5M - $2M loan: 9 months common
- Above $2M loan: 12 months or more
Reserves can include savings accounts, money market accounts, stocks, bonds, and vested retirement funds (typically counted at 60-70% of value).
Debt-to-Income Ratio
Most jumbo lenders cap total DTI at 43%. Some allow up to 45% with strong compensating factors (high credit score, large reserves, significant residual income).
Income Documentation
Jumbo underwriting is thorough. Expect to provide:
- 2 years of W-2s
- 2 years of federal tax returns (all pages, all schedules)
- 30 days of pay stubs
- 2 months of bank and investment statements
- Employment verification
Self-employed borrowers need 2 years of business tax returns, a year-to-date P&L, and often a CPA letter confirming business status.
Benefits of 20% Down on Jumbo
No PMI
Unlike 10% down jumbo options, 20% down means no private mortgage insurance and no rate adjustments to compensate for higher LTV risk.
Best Available Rates
Jumbo rates at 80% LTV are typically 0.125-0.25% lower than 90% LTV rates. On a $1.5M loan, that's $156-$312/month in interest savings.
Wider Lender Selection
Nearly every jumbo lender offers 80% LTV products. At 90% LTV, your options narrow to lenders with specific high-LTV jumbo programs.
Easier Approval on Higher Loan Amounts
For loans above $2M, many lenders require 20% minimum. Having 20% down opens the door to the full range of luxury home financing.
Jumbo Rate Environment
Jumbo rates have converged with conforming rates in recent years. In some cases, jumbo rates are actually lower than conforming rates for well-qualified borrowers. This happens because jumbo lenders keep these loans on their books (portfolio lending) and compete aggressively for high-net-worth borrowers.
At 20% down with a 760+ credit score, expect jumbo rates within 0.125% of conforming rates, and sometimes at parity.
Property Considerations
Jumbo loans are available for:
- Single-family homes: Straightforward, widest availability
- Condos: Building must meet lender requirements (HOA reserves, owner-occupancy ratios, litigation status)
- Townhomes: Generally treated like single-family
- Second homes: Available at 20% down, may have rate premium
- Investment properties: Often require 25%+ down

- Queen Anne (upper)

The Underwriting Timeline
Jumbo loans typically take 30-45 days to close, slightly longer than conforming loans due to additional documentation review. Complex income situations (multiple businesses, RSU compensation, foreign income) may extend the timeline.
Getting pre-approved before shopping is especially important for jumbo buyers. Sellers of higher-priced homes expect to see proof of financing, and a thorough pre-approval signals you're ready to close.
