In Seattle neighborhoods like Capitol Hill, Eastlake, Madison Park, and Laurelhurst, homes regularly exceed $1.2-1.5 million. At these price points, buyers cross into jumbo loan territory, where different rules apply. The good news: you don't necessarily need 20% down. Many lenders now offer 10% down jumbo options for borrowers with strong credit and income.
When Does a Loan Become "Jumbo" in King County?
A loan is considered jumbo when it exceeds the local conforming limit. For King County in 2026, that limit is $1,063,750 for a single-family home. So:
- At 10% down: any home above ~$1,181,944 requires a jumbo loan
- At 20% down: any home above ~$1,329,688 requires a jumbo loan
10% Down Jumbo Requirements
Jumbo loans have stricter underwriting than conforming loans. With 10% down, expect these typical requirements:
Credit Score
Most lenders require a minimum 700-720 credit score for 10% down jumbo loans. Some may go to 680, but you'll pay higher rates and may face additional requirements.
Cash Reserves
Lenders want to see you have staying power. Expect to show 6-12 months of mortgage payments in liquid reserves (savings, investments, retirement accounts) after closing. On a $1.4M home with a $7,500 monthly payment, that's $45,000-$90,000 in reserves.
Debt-to-Income Ratio
Most jumbo lenders cap DTI at 43%, though some allow up to 45% with compensating factors like excellent credit or substantial reserves.
Income Documentation
Full documentation is standard: 2 years of W-2s and tax returns, recent pay stubs, and verification of employment. Self-employed borrowers need 2 years of business tax returns and may need a CPA letter.
Down Payment Math for Seattle Jumbo
| Home Price | 10% Down | Loan Amount |
|---|---|---|
| $1,300,000 | $130,000 | $1,170,000 |
| $1,500,000 | $150,000 | $1,350,000 |

Jumbo Rates vs. Conforming Rates
Historically, jumbo rates ran 0.25-0.50% higher than conforming rates. Today, the spread has narrowed considerably, and some jumbo products are priced competitively with conforming loans, especially for borrowers with 740+ credit scores.
At 10% down, you may see rates 0.125-0.25% higher than 20% down jumbo rates, depending on the lender and your overall profile.
Private Mortgage Insurance on Jumbo Loans
Not all jumbo loans require PMI at 10% down. Some lenders:
- Price the PMI into the rate (higher rate, no monthly PMI payment)
- Require PMI but at lower rates than conforming loans
- Offer "piggyback" structures (80% first mortgage + 10% second mortgage + 10% down)
Julie can compare structures to find the lowest total monthly cost for your situation.
Loan Amount Tiers
Some lenders have pricing tiers for jumbo loans:
- $1,037,301 - $1,500,000: Standard jumbo pricing
- $1,500,001 - $2,000,000: May require 15% down or higher credit score
- $2,000,001 - $3,000,000: Often requires 15-20% down
- Above $3,000,000: Typically requires 20-25% down
The 10% down option is most widely available for loans under $2M.
Property Types
Jumbo loans at 10% down are typically available for:
- Single-family primary residences
- Some condos in approved buildings
- Townhomes
Second homes and investment properties usually require 20%+ down. Condos may face additional scrutiny on HOA financials and owner-occupancy ratios.
Comparing to 20% Down Jumbo
| Factor | 10% Down | 20% Down |

| Down payment on $1.5M | $150,000 | $300,000 |
| Credit score minimum | 700-720 | 680-700 |
| Reserve requirement | 9-12 months | 6-9 months |

When 10% Down Jumbo Works Well
- You have 720+ credit and want to preserve cash for reserves
- You're buying in the $1.2M-$1.8M range
- You have strong verifiable income relative to the payment
- You expect significant income growth or bonus income ahead
When to Consider 20% Down Instead
- You're buying above $2M where 10% down options are limited
- Your credit score is in the 680-700 range
- You want the best possible rate
- You're buying a condo that may have stricter requirements
