Seattle's median home price hovers around $850,000, so even a small down payment represents serious cash. A 3% down conventional loan lets you buy with roughly $25,500 down on an $850,000 home instead of $170,000 at 20%. For buyers who have strong income but haven't had years to stockpile savings, this path can shave years off the timeline to homeownership.
What Is a 3% Down Conventional Loan?
A conventional loan is mortgage financing that isn't backed by a government agency like FHA or VA. Instead, it follows guidelines set by Fannie Mae or Freddie Mac. Both agencies now allow qualified borrowers to purchase with just 3% down through specific programs:
- HomeReady (Fannie Mae): Requires income at or below 80% of the area median income (AMI). In King County, that threshold is approximately $103,000 for a single borrower based on current HUD data.
- Home Possible (Freddie Mac): Similar 80% AMI income cap with slightly different underwriting guidelines.
- Standard 97% LTV: For first-time buyers who don't meet income limits, some lenders offer a conventional 97 program with at least one borrower who hasn't owned a home in the past three years.
King County Loan Limits for 2026
In King County, the conforming loan limit for a single-family home is $1,063,750 for 2026. That means you can finance up to that amount with a conventional loan before crossing into jumbo territory. With 3% down, you could purchase a home priced up to about $1,096,600 and still stay within conforming limits.
Down Payment Math for Seattle
| Home Price | 3% Down | Loan Amount |
|---|---|---|
| $700,000 | $21,000 | $679,000 |
| $850,000 | $25,500 | $824,500 |
| $1,000,000 | $30,000 | $970,000 |
Credit Score Requirements
HomeReady accepts credit scores as low as 620, though better scores unlock lower PMI rates. Home Possible typically requires a minimum 660 score. In practice, most Seattle buyers applying for 3% down financing have scores in the 700+ range, which helps keep monthly costs competitive.
Private Mortgage Insurance (PMI)
Any conventional loan with less than 20% down requires PMI. The good news: PMI on conventional loans can be canceled once you reach 20% equity, unlike FHA's lifetime mortgage insurance on most loans.
PMI rates vary based on credit score and loan-to-value ratio. On a 3% down loan:
- 780+ credit score: ~0.35% annually ($240/month on an $825,000 loan)
- 720 credit score: ~0.75% annually ($515/month)
- 680 credit score: ~1.15% annually ($790/month)
HomeReady and Home Possible offer reduced PMI rates for qualifying borrowers, which can save $50-150/month compared to standard conventional PMI.
Income Limits and Eligibility
For HomeReady and Home Possible, your income cannot exceed 80% of the area median income. In King County's high-cost market, that limit is higher than in most U.S. counties. You can check your eligibility using Fannie Mae's AMI lookup tool or ask Julie to run the numbers for your specific situation.
If your income exceeds the limit, you may still qualify for a standard Conventional 97 loan if at least one borrower is a first-time buyer (no homeownership in the past three years).
Gift Funds and Down Payment Assistance
Both HomeReady and Home Possible allow 100% of your down payment to come from gift funds. You don't need to contribute any of your own savings. The gift must come from an acceptable source (family member, domestic partner, employer, or approved down payment assistance program) with proper documentation.
Washington State also offers programs like WSHFC Home Advantage that can be layered with conventional financing.
Homeownership Education Requirement
If all borrowers on the loan are first-time buyers, at least one must complete a homeownership education course. Fannie Mae's free HomeView course satisfies this requirement and takes about 4-6 hours to complete online.
When 3% Down Makes Sense
- You have strong income and credit but limited savings
- You want to keep cash reserves for moving costs, repairs, or emergencies
- Seattle home prices are rising and you'd rather buy now than wait to save more
- You expect your income to grow, making it easy to pay down principal and remove PMI faster
When to Consider a Higher Down Payment
- Your credit score is below 700, which means PMI will be expensive
- You're buying near the conforming limit and need to stay under $1,063,750
- You want the lowest possible monthly payment from day one
