The 20 percent down rule is the most expensive myth in real estate. It keeps people renting for years while they chase a number nobody actually requires.

I've had buyers walk in convinced they needed $160,000 in cash to buy in Seattle, and walk out under contract with a fraction of that. Let me bust this myth for good and show you what it really takes.

Do you really need 20% down to buy a house in Seattle?

No, you do not need 20 percent down to buy a house in Seattle. That's a leftover rule of thumb from a different era, and today most buyers put down far less, many under 5 percent.

The 20 percent figure became gospel because it's the threshold where you avoid private mortgage insurance. That's it. It was never a requirement to buy. Somewhere along the way it morphed into this hard wall in people's heads, and that wall has cost more would-be owners more money than almost any other myth in this business.

Here's the reframe: putting down less isn't "cheating" or "doing it wrong." It's a tool. A smart buyer uses the lowest sensible down payment to get into an appreciating asset sooner, then builds equity from there. Waiting for 20 percent is often the genuinely worse financial move.

What loan options let you buy with less than 20% down?

Plenty of loan programs let you buy with far less than 20 percent down, and each fits a different buyer. The four big ones are FHA, conventional, VA, and down payment assistance.

FHA loans let you buy with just 3.5 percent down. They're forgiving on credit and built for first-time and lower-down buyers. Conventional loans can go as low as 3 to 5 percent down for qualified first-time buyers, and they let you drop mortgage insurance sooner. VA loans are the unicorn: zero percent down for eligible veterans and service members, with no monthly mortgage insurance at all. If you've served, this is one of the best loan products in America and you should not leave it on the table.

On a Seattle home, the difference is enormous. Twenty percent down on an $819,000 home is over $160,000. At 3.5 percent, you're talking closer to $29,000. That's the gap between "someday" and "this year."

What are down payment assistance programs in Washington?

Down payment assistance programs are loans or grants that help cover your down payment and closing costs, often aimed at first-time buyers or buyers under certain income limits. Washington has several, and most people have never heard of them.

The Washington State Housing Finance Commission runs programs that pair a main mortgage with a second loan to cover much of your down payment, sometimes with payments deferred until you sell or refinance. There are also local and lender-specific programs that pop up depending on the area and your situation. The catch is that these change, have eligibility rules, and aren't always advertised loudly, which is exactly why working with a lender and agent who know the current menu matters.

The point is this: if cash is your only obstacle, you may have more options than you realize. Don't assume you're stuck before you've actually asked.

What is PMI and is it really that bad?

PMI is private mortgage insurance, an extra monthly cost you pay when you put down less than 20 percent. It protects the lender, not you, and yes it's an added expense, but it's nowhere near the deal-breaker people think.

Here's the part that changes the math: PMI is removable. Once you build enough equity in the home, typically around that 20 percent mark through payments and appreciation, you can have it dropped. So it's not a permanent tax. It's a temporary toll for getting in years earlier. On most Seattle homes it runs a manageable amount per month, often far less than what people imagine and almost always less than the rent you'd keep paying while you save.

Think of PMI as the cost of the head start. You pay it for a while, you build equity, then it goes away, and you're left owning a home you'd otherwise still be renting around.

Doesn't waiting to save 20% actually save me money?

Usually no. In a rising market like Seattle, waiting to save a full 20 percent often costs you more than it saves, because home prices and interest rates don't sit still while you save.

Run the trap forward. Say you spend three more years stacking cash for 20 percent down. During those three years, you're paying rent you never get back, the target home price climbs (the 2026 forecast is a modest 2 to 4 percent annual rise on a median near $819,000), and 20 percent of a bigger number is a bigger pile of cash you now have to chase. Meanwhile rates may move in either direction, outside your control. You can easily end up needing more money, for a more expensive house, after years of paying someone else's mortgage.

The buyer who got in early with 5 percent down was building their own equity that whole time. Waiting feels responsible. The math often says otherwise.

What mistakes do buyers make around down payments?

The biggest mistake is assuming you need 20 percent and never even asking the question. Right behind it: draining every dollar you have into the down payment and leaving nothing for reserves.

Don't show up to closing with an empty bank account. You want a cushion for moving costs, repairs, and life. Sometimes a lower down payment with healthy reserves is smarter than a bigger one that leaves you house-poor. Other common misses: not shopping loan programs against each other, not asking about assistance programs, and skipping pre-approval so you're guessing at your real budget. Every one of these is fixable with one good conversation up front.

Is now a good time to buy in Seattle with less down?

Yes, 2026 is a solid time to buy with a lower down payment because the market is more balanced and buyers have more leverage than they've had in years. Rising inventory means more room to negotiate.

It's a property-type market: detached homes are still the most competitive segment, but condos are a buyer's market right now, which is great news for first-timers using low-down loans. With the median around $819,000 and a modest 2 to 4 percent rise forecast, the cost of waiting to save more is real. If you can get in responsibly now with 3 to 5 percent down, you're often better off than holding out for a 20 percent number that keeps growing.

How do you get started?

Start by finding out what you actually qualify for. A quick pre-approval conversation usually reveals you can do more, with less, than you assumed.

You probably need less than you think. Let's find out for real.

Frequently Asked Questions

Do you need 20% down to buy a house in Seattle?

No, you do not need 20 percent down to buy a house in Seattle. Most buyers put down far less, many under 5 percent. The 20 percent figure is simply the threshold to avoid private mortgage insurance, not a requirement to buy. Low-down options let you get into an appreciating asset years sooner.

What loan options allow less than 20% down in Seattle?

FHA loans allow 3.5 percent down, conventional loans can go as low as 3 to 5 percent for qualified first-time buyers, and VA loans offer zero down with no monthly mortgage insurance for eligible veterans and service members. Washington also offers down payment assistance programs to help cover down payment and closing costs.

What is PMI and can you get rid of it?

PMI is private mortgage insurance, a monthly cost paid when you put down less than 20 percent, and it protects the lender. It is removable. Once you build roughly 20 percent equity through payments and appreciation, you can have it dropped, so it is a temporary toll for getting into a home years earlier, not a permanent expense.

Does waiting to save 20% down save you money in Seattle?

Usually not. In a rising market like Seattle, waiting to save a full 20 percent often costs more than it saves because home prices climb while you save, rent is money you never get back, and 20 percent of a higher price is a larger amount. With a 2 to 4 percent annual price rise forecast, getting in earlier with 3 to 5 percent down is frequently the better move.
