What Down Payment Do You Need to Buy a Home in Sammamish?
A down payment is the cash you bring to closing on top of your mortgage, and in Sammamish it is the single biggest number most buyers plan around. Because the city's median sale price sits near $1.57 million, according to Redfin market data, even a modest percentage turns into a large dollar figure. The encouraging part is that you rarely need the full 20% that many buyers assume.
We are The Van Pelt Group at John L. Scott, a multi-generational Sammamish-area team, and down payment planning is one of the first conversations we have with every buyer. Below we break down the percentages, the loan types, and the costs that sit next to the down payment itself.
How Much of a Down Payment Do Sammamish Homes Require?
Because Sammamish prices run high, the percentage you choose has an outsized effect on the cash you bring to closing. Here is how common down payment levels translate against a roughly $1.5 million purchase, close to the city's 2026 median sale price.
- 3% down: about $45,000, available on some conventional loans for qualified buyers
- 5% down: about $75,000, a common conventional starting point
- 10% down: about $150,000, a frequent entry point for jumbo loans
- 20% down: about $300,000, which removes mortgage insurance and strengthens an offer
The percentage is only half the story. The loan program you qualify for sets the floor, and at Sammamish price points it also decides whether you shop with a conventional or a jumbo loan. That distinction drives almost everything about your minimum down payment.
Down Payment by Loan Type in Sammamish
Most buyers in Sammamish use one of four loan types. Each carries its own minimum, and each interacts with the area's elevated prices in a slightly different way.
Conventional loans: 3% to 5% to start
Conventional loans allow as little as 3% to 5% down for well-qualified buyers, which is the lowest practical entry point for most Sammamish purchases. Anything under 20% adds private mortgage insurance, a monthly cost that falls away once you reach about 20% equity. The catch is that conventional pricing only stretches to the conforming loan limit, and many Sammamish homes sit above that ceiling.
Jumbo loans: usually 10% to 20%
A jumbo loan covers any amount above the conforming limit, and in 2026 that limit in high-cost King County sits above $1.2 million. Since the typical Sammamish home still prices above that line, a large share of buyers here use a jumbo. Lenders generally ask for 10% to 20% down on a jumbo, along with stronger credit and several months of cash reserves.
Two government-backed programs round out the picture, though both run into Sammamish price ceilings:
- FHA loans allow 3.5% down, but FHA loan limits in King County often fall below Sammamish prices, which narrows the homes you can buy with one.
- VA loans offer zero down for eligible veterans and service members. Above the local limit, a VA jumbo may ask for a partial down payment, so the exact figure depends on the purchase price.
Why Most Sammamish Buyers Use a Jumbo Loan
The conforming loan limit is the dividing line between a conventional loan and a jumbo loan, and Sammamish sits squarely on the jumbo side for most purchases. That is not a problem, it is simply the standard path for a market where the median home runs near $1.57 million.
Jumbo loans reward preparation. Lenders typically want a credit score in the strong-to-excellent range, a lower debt-to-income ratio, and cash reserves equal to several months of payments after closing. A buyer who knows a jumbo is likely can save toward a 10% to 20% down payment and the reserves at the same time. We walk buyers through these requirements with their lender before the search begins, so the budget you tour with is the budget you can actually close on.

Beyond the Down Payment: Closing Costs and Reserves in Sammamish
The down payment is the largest line item, but it is not the only cash you need at closing. Closing costs in Washington generally run 2% to 5% of the purchase price and cover lender fees, title and escrow, appraisal, and prepaid property taxes and insurance. On a $1.5 million Sammamish home, that is another $30,000 to $75,000 to budget for.
Two more figures belong in your plan. Earnest money, the good-faith deposit you submit with an offer, is often 1% to 3% of the price and later applies toward your down payment. Many Sammamish neighborhoods such as Klahanie and Sahalee also carry HOA dues of about $50 to more than $300 a month, which affect your monthly budget rather than your down payment.

Frequently Asked Questions
How much do you need to put down on a $1.5 million home in Sammamish?
On a $1.5 million Sammamish home, a 5% down payment is about $75,000, 10% is about $150,000, and 20% is about $300,000. Most homes at this price use a jumbo loan, which commonly asks for 10% to 20% down. Your exact figure depends on the loan program you qualify for and how much you choose to put down to manage your monthly payment.
Do you need 20% down to buy a home in Sammamish?
No. Conventional loans can start at 3% to 5% down, and jumbo loans often start at 10%. Putting 20% down removes private mortgage insurance and can strengthen your offer, but it is not a requirement. Many Sammamish buyers put down less and direct the difference toward reserves, closing costs, or keeping savings on hand for the move.
What is a jumbo loan and why do Sammamish buyers need one?
A jumbo loan finances any amount above the conforming loan limit, which in high-cost King County sits above $1.2 million in 2026. Because the typical Sammamish home prices above that line, a large share of buyers here use a jumbo. These loans usually require 10% to 20% down, a strong credit profile, and several months of cash reserves after closing.
Can first-time buyers afford a down payment in Sammamish?
It is challenging given the price point, but it happens, especially for dual-income households working at Eastside tech employers. Conventional loans with 3% to 5% down lower the cash needed up front, and Washington's lack of a state income tax can help buyers save faster. We often help first-time buyers compare a smaller down payment with mortgage insurance against a larger one to fit their monthly budget.
What is the average home price in Sammamish in 2026?
Redfin puts the Sammamish median sale price near $1.57 million in early 2026, with homes typically going pending in under a month. Prices vary widely by neighborhood, from family communities like Klahanie in the $900,000s to $1.5 million range up to luxury and waterfront homes well into seven figures.
How much are closing costs in Sammamish?
Closing costs in Washington generally run 2% to 5% of the purchase price and are separate from your down payment. On a $1.5 million Sammamish home, that is roughly $30,000 to $75,000, covering lender fees, title and escrow, appraisal, and prepaid taxes and insurance. Your lender provides a loan estimate early in the process so you can plan for the full amount of cash to close.
