Is 20% Down Still the Gold Standard for Seattle Home Buyers?

For decades, 20% down was the default advice for home buyers. No PMI, lower monthly payments, stronger negotiating position. But with Seattle's median home price around $850,000, that advice translates to saving $170,000 before you can buy. For many buyers, that's years of additional rent paid while prices continue rising.

So is 20% down still worth pursuing? The answer depends on your specific financial situation, timeline, and opportunity cost.

What 20% Down Looks Like in Seattle

The Benefits of 20% Down

No Private Mortgage Insurance

PMI typically costs 0.2%-1.2% of your loan amount annually, depending on credit score and LTV. On an $800,000 loan, that's $133-$800/month. With 20% down, you skip this entirely.

Lower Monthly Payment

A smaller loan means a smaller payment. On an $850,000 home at 7% interest:

• 10% down ($765K loan): ~$5,090/month P&I + ~$200 PMI = $5,290
• 20% down ($680K loan): ~$4,524/month P&I + $0 PMI = $4,524
• Monthly savings: ~$766

Instant Equity Cushion

Starting with 20% equity means you can weather a market correction without going underwater. If prices drop 10%, you still have equity. Buyers who put 3-5% down in a declining market can find themselves owing more than their home is worth.

Stronger Competitive Position

In multiple-offer situations, a 20% down buyer signals financial strength. Some sellers prefer these buyers over those with minimal down payments, viewing them as lower risk to close.

The Case Against Waiting for 20%

Opportunity Cost of Waiting

If you currently have $85,000 saved (10% of an $850K home) and need another $85,000 to reach 20%, how long will that take? At $2,000/month savings, that's 42 months or 3.5 years.

During those 3.5 years:

• You pay rent instead of building equity (perhaps $3,000/month = $126,000)
• Home prices may rise 3-5% annually (potentially $75,000-$125,000 on an $850K home)
• Your target down payment increases as prices rise

PMI Isn't Permanent

Unlike FHA mortgage insurance, conventional PMI can be removed once you reach 20% equity through payments, appreciation, or a combination. Many Seattle buyers who put 10% down find they can remove PMI within 2-4 years as home values rise.

The Money Has Other Uses

That extra $85,000 could:

• Stay invested in the market (historically ~7-10% annual returns)
• Serve as an emergency fund
• Pay for renovations that increase home value
• Fund retirement accounts

When 20% Down Makes Clear Sense

• You have the cash available without depleting emergency reserves
• You're buying at the conforming limit and need to minimize your loan to stay under $1,063,750
• You're risk-averse and value the equity cushion
• You're buying a second home or investment property (often requires 20%+)
• Your credit score is below 700, making PMI expensive

When 10% or Less Down Might Be Smarter

• You'd deplete your emergency fund to reach 20%
• Your credit score is 740+ (PMI will be cheap)
• You expect Seattle prices to continue rising
• You'd rather invest the difference in the market
• You're confident you'll hit 20% equity through appreciation within a few years

Conforming Limit Considerations

King County's 2026 conforming limit is $1,063,750. With 20% down, you can purchase a home up to $1,329,688 while keeping the loan under the limit:

$1,063,750 ÷ 0.80 = $1,329,688 max purchase price

This is significantly higher than the ~$1,181,900 ceiling at 10% down. For buyers shopping in the $1.2M-$1.33M range, 20% down can be the difference between a conforming loan and a jumbo loan with stricter requirements.

Running the Break-Even Math

Julie can calculate your specific break-even point: how long it takes for PMI savings at 20% down to offset the opportunity cost of tying up extra cash. For many Seattle buyers with good credit, the math favors putting less down and investing the difference, but every situation is different.
