When most people picture buying their first home in Seattle, they picture the mortgage payment. They plug a price and a rate into a calculator online, see a number, and decide whether it feels doable. I get it. That number is the headline. But it is not the whole story, and I have sat across from too many first-time buyers who found that out after they had the keys.
The mortgage is the part everyone talks about. The rest of it, taxes, insurance, utilities, upkeep, is the part that quietly decides whether a home feels comfortable or tight every single month. So let me walk you through what owning a Seattle home actually costs in 2026, line by line, the way I would if we were sitting down together.
Start With the Mortgage, But Do Not Stop There
Let us use a real example. Say you buy near the King County median, around 875,000 dollars, with 10 percent down and a 30-year loan in the mid-6 percent range where rates have been sitting this year. Principal and interest alone lands somewhere in the neighborhood of 4,900 to 5,000 dollars a month.
That is the number the online calculator shows you. Here is everything it leaves out.
Property Taxes: The Big One People Forget
King County property taxes run a little under 1 percent of value in most Seattle neighborhoods, and for 2026 the typical bill climbed again. On a home around 875,000 dollars, you are looking at roughly 7,500 to 8,500 dollars a year, which works out to about 625 to 700 dollars a month.
Most buyers pay this through an escrow account bundled into their monthly payment, so it does not arrive as a separate bill. That is convenient, but it also means your "mortgage" is really your mortgage plus a few hundred dollars you never see leave your hands. Taxes also tend to rise over time, so I always coach clients to budget for a little more each year, not a flat number.
Homeowners Insurance
Insurance in Seattle is more reasonable than a lot of the country. We are not Florida or California when it comes to catastrophe risk. For a typical single-family home here, plan on somewhere around 1,400 to 2,000 dollars a year, or roughly 120 to 170 dollars a month, depending on your coverage, deductible, and the age of the home.
If you are putting less than 20 percent down, you will also carry private mortgage insurance, or PMI, until you build enough equity. On a loan this size that can add another 150 to 300 dollars a month. It is not permanent, and I will show you how to plan for dropping it, but you need to count it while it is there.
Utilities: Higher Than New Buyers Expect
This is the category that surprises people most, especially anyone moving from an apartment. Seattle utilities are not cheap. Between electricity, water, sewer, garbage, and gas, a single-family home often runs 350 to 550 dollars a month. Sewer and garbage through Seattle Public Utilities alone can be a bigger line item than you would guess.
An older or larger home costs more to heat. A newer or well-insulated one costs less. Either way, when you go from renting to owning, this is a real jump, and it is worth asking a seller what their typical bills look like before you write an offer.
Maintenance and Repairs: Pay Yourself First
Here is the one nobody wants to hear. When you own, there is no landlord to call. The water heater, the roof, the furnace, the gutters, all of it is yours now. A common rule of thumb is to set aside about 1 percent of your home's value each year for upkeep. On an 875,000 dollar home that is around 8,750 dollars a year, or a little over 700 dollars a month.
You will not spend that every month. Some months are quiet and some months a repair eats the whole cushion at once. The point is to treat it like a bill you pay to yourself so a surprise does not turn into a crisis. Older Seattle homes, and we have a lot of beautiful older homes, tend to need more attention, so factor in the age of what you buy.
Do Not Forget HOA Dues
If you are buying a condo or a townhome, which is often the smartest entry point into Seattle right now, you will also have monthly HOA dues. These commonly run 400 to 800 dollars a month, sometimes more in buildings with elevators, concierge service, or amenities. Dues cover shared maintenance and reserves, so a well-run HOA is a feature, not just a cost. I always read the HOA financials with my buyers before we commit.
Adding It All Up
Stack those pieces on top of that 4,900 dollar mortgage and the real monthly cost of owning that median Seattle home can land closer to 7,000 to 7,500 dollars once you include taxes, insurance, utilities, and a genuine maintenance reserve. That is a meaningful gap from the calculator number, and it is exactly the gap that catches people off guard.
I do not share this to scare you off. I share it because knowing the real number is what lets you buy with confidence instead of anxiety. When you plan for the whole cost up front, homeownership feels steady. When you only plan for the mortgage, every repair feels like an emergency.
The Bottom Line
Owning a home in Seattle is still one of the best long-term moves most people can make, and the rising inventory this year has given buyers more room to negotiate than we have seen in a while. But the smart way to buy is with your eyes open to the full monthly picture, not just the headline payment.
