After 26 years as a Seattle loan officer, one of the most common questions I hear from first-time homebuyers is:
"How much house can I actually afford?"
It sounds like a simple question. It isn't.
Seattle's average home price reached $1,036,512 in July 2026 (The Madrona Group). Inventory is up 22% year over year, while pending sales are down 9.2%. You might assume that means affordability is improving.
For many buyers, it isn't.
The biggest issue I see isn't whether someone can qualify for a mortgage. It's whether the payment they qualify for actually fits the life they want to live.
I regularly meet with buyers who have already used an online mortgage calculator. They've entered their income, estimated a down payment, and come to the meeting convinced they know their price range.
A buyer earning $190,000 might see a calculator suggest that a $700,000+ mortgage is possible.
But that's only the beginning of the conversation.
The real questions are:
What will the total monthly payment be? How much cash will you need at closing? What happens to your emergency savings after you buy? Can you still contribute to retirement, travel, invest, and handle an unexpected $10,000 expense?
That is the affordability calculation that matters.
The Most Important Number Isn't Your Pre-Approval
Here is a scenario I see all the time.
A buyer is pre-approved to purchase an $850,000 home.
They have the income. They have good credit. They have the down payment. Automated underwriting approves the loan.
Then we look at the actual monthly payment: principal, interest, property taxes, homeowners insurance, mortgage insurance if applicable, and HOA dues if there are any.
Suddenly, the conversation changes.
The buyer realizes the payment I am describing does not match what the calculator showed. The thought I hear most often is: I qualify for this payment, but this payment doesn't fit my life.
That distinction is critical.
In my experience, many well-qualified Seattle buyers can be approved for substantially more than they are comfortable spending every month.
Your maximum loan approval should not automatically become your home-buying budget.
The Bottom Line
So, how much house can you afford in Seattle in 2026?
It isn't simply the maximum amount a lender will approve.
It is the home price that gives you a payment you can comfortably make while still allowing you to save, invest, handle emergencies, and enjoy your life.
After 26 years in mortgage lending, that is the affordability number I care about most.
Get qualified for the maximum. Buy based on your comfort.
Those are two different numbers — and understanding the difference before you make an offer can completely change your home-buying experience.
My Advice of Financing Seattle Homebuyers
Before you start seriously shopping for homes, determine these four numbers:
Your comfortable total monthly housing payment
Your available cash for down payment and closing costs
The amount you want left in reserves after closing
Then compare them.
That exercise often tells us far more than an online affordability calculator ever will.
If the lender says you can purchase at $900,000 but your preferred payment points toward $800,000, your budget wins.
There is nothing wrong with buying below your maximum qualification. In fact, for many first-time buyers, that flexibility is one of the smartest financial decisions they can make.
How Much Should a First-Time Buyer Put Down in Seattle?
This is another area where generic advice can be misleading.
You do not necessarily need 20% down to buy a home.
Depending on the borrower and loan program, there may be conventional options with 3% or 5% down, FHA financing with 3.5% down, VA financing with no down payment for eligible borrowers, and various assistance programs.
But the minimum down payment and the right down payment are not necessarily the same.
In Seattle's higher-priced housing market, increasing the down payment can sometimes make a meaningful difference in the monthly payment.
But I also don't automatically recommend putting every available dollar into the house.
If putting 20% down leaves you with almost nothing in savings, while putting 15% down allows you to maintain a healthy emergency fund, the second option may be the stronger financial position.
Liquidity matters after you become a homeowner. The goal isn't simply to eliminate PMI or achieve a certain LTV. The goal is to structure the mortgage around your broader financial picture.
Qualified vs. Comfortable: The $6,200 Question
Depending on the loan program, borrower profile, reserves, credit, and automated underwriting findings, conventional financing can potentially allow total DTI ratios approaching 50%.
Start With the Payment, Then Work Backward
This is one of the biggest changes I recommend first-time buyers make.
Don't start with the maximum home price. Start with the monthly payment.
Consider what total housing payment you would feel comfortable making every month.
Maybe that's $4,500. Maybe it's $5,000. Maybe it's $6,000.
There is no universally correct percentage.
Once we establish the payment, we can work backward and determine the home price and loan structure that fit it.
For example, instead of saying you earn $190,000 and asking how much you can borrow — I would rather have a buyer tell me they earn $190,000, but they want their total housing payment around $5,000 and they want to keep at least $50,000 in reserves after closing.
Now we can build an actual mortgage strategy. That's a much better conversation.
Now we can build an actual mortgage strategy. That's a much better conversation.
But that doesn't mean 50% should be your number.
Consider a household earning $190,000 per year.
That is approximately $15,833 per month in gross income.
At a 50% total DTI, roughly $7,916 per month could potentially be allocated toward qualifying monthly obligations.
That sounds like plenty of room.
But now consider a hypothetical $900,000 Seattle home with 10% down. Depending on the interest rate, property taxes, insurance, and mortgage insurance, the total housing payment could approach $6,000+ per month.
Then add:
$400 car payment
$250 student loan payment
Credit cards or other monthly obligations
Utilities
Childcare
Groceries
Retirement contributions
Travel
Emergency savings
Home maintenance
Some of those expenses aren't included in the lender's DTI calculation.
Your life doesn't operate on DTI.
That is why I tell first-time buyers that there are really two affordability numbers:
1. What you can qualify for 2. What you can comfortably afford
The second number matters more.
Why Online Mortgage Calculators Often Get Seattle Affordability Wrong
Online calculators can be useful for getting a rough estimate, but they often oversimplify the variables that have the biggest impact on a Seattle buyer's actual payment.
Down payment. Putting 5%, 10%, 15%, or 20% down can significantly change the loan amount, mortgage insurance, interest rate, and cash reserves you have left after closing.
Property taxes. These vary by property and location and need to be calculated accurately.
Homeowners insurance. A generic estimate may not reflect the actual property.
Mortgage insurance. PMI isn't a single fixed percentage. It can vary considerably based on credit, LTV, loan structure, and other factors.
HOA dues. For Seattle condos and some townhomes, HOA dues can materially change purchasing power.
Closing costs and reserves. Having enough for the down payment doesn't necessarily mean you have enough cash to comfortably close and still maintain adequate savings. Many buyers in my appointment mention 3% for closing costs. This is not true for Seattle, the greater eastside, King, Pierce or Snohomish county's. In fact, in most cases I see closings costs and prepaids at 1.5%to 2% of the sales price.
And then there is the biggest variable of all:
Your lifestyle.
A lender doesn't know how much you want to save each month, how often you travel, whether you're planning to have children, or whether maxing out retirement accounts is important to you. A calculator doesn't know either.
All of the above begins with a conversation, are you looking for how much you can afford? Let's connect to walk through the numbers.
