When buyers sit down across from me for the first time, they usually want to talk about houses. Neighborhoods, square footage, that kitchen they saw on Zillow at 11pm. I get it. But before we tour a single home, there is one number that quietly decides how much house you can buy in Seattle, and most people have never heard of it: your debt-to-income ratio.

It is not flashy. It will not show up in a listing photo. But your DTI is one of the first things a lender looks at, and it often matters more than your credit score or your down payment. Here is how it works, what number you actually need, and how to move it in your favor before you start shopping.

What Your Debt-to-Income Ratio Actually Is

Your debt-to-income ratio is simple math. It compares how much you owe each month to how much you earn each month, before taxes. Lenders use it to answer one question: if we hand you a mortgage, can you comfortably carry it on top of everything else you already pay?

There are two versions of the number, and both matter. Your front-end ratio looks at just your future housing payment (principal, interest, property taxes, homeowners insurance, and any HOA dues) as a percentage of your gross monthly income. Your back-end ratio adds in your other monthly debts: car payments, student loans, credit card minimums, personal loans. That back-end number is usually the one lenders weigh most heavily.

Here is a quick example. Say you earn $9,000 a month before taxes, and your total monthly debts, including your new mortgage, would come to $3,600. That is a 40 percent back-end DTI. Simple as that.

The DTI Numbers You Actually Need

This is where it gets practical. Different loan programs draw the line in different places, and knowing the ranges helps you understand what you are working with.

1. Conventional loans: lenders like to see a back-end DTI at or below 36 percent, though many will stretch to 45 percent, and sometimes near 50 percent, if you have strong credit or a healthy down payment.
2. FHA loans: more forgiving. Guidelines land around 43 percent, but with compensating factors like solid savings or a strong credit score, buyers are often approved above that, sometimes close to 50 percent.
3. VA loans: for eligible veterans and active-duty buyers, there is no hard cap. The VA uses 41 percent as a guideline but leans on residual income, the money left over each month after your big bills are covered.

The honest takeaway: anything under 36 percent is the zone where programs approve you without much argument and tend to price you best. Above that, you can still buy. You just need the rest of your file to be strong.

What This Means in Seattle's Market

Seattle is not a cheap market. The median sale price sits around $869,500 right now, and 30-year rates are holding in the low 6 percent range. On a home in that range, your monthly payment climbs quickly once you add property taxes and insurance. That is exactly why your DTI carries so much weight here. The higher our local prices, the more your existing debts eat into what you can borrow.

The flip side is good news. Inventory has climbed over the past year, and Seattle has shifted from a low-supply frenzy into a more balanced market with roughly three to three and a half months of supply. That gives you a little more breathing room to get your finances lined up before you compete, instead of throwing an offer at the first house you walk through.

How to Improve Your DTI Before You Buy

If your ratio is higher than you would like, you have more control than you think. Here are the moves that actually work:

1. Pay down revolving debt first. Knocking out a credit card balance or a small car loan lowers your monthly obligations right away, which drops your back-end ratio faster than almost anything else.
2. Do not take on new debt. The months before you buy are the worst time to finance a car or open a new card. Lenders re-check your numbers right before closing.
3. Increase documented income. A raise, a side income with a real track record, or adding a co-borrower can all shift the math in your favor.
4. Buy a little less house. Stretching to your absolute maximum feels tempting, but a slightly lower price keeps your ratio healthy and your monthly life comfortable.
5. Ask about a rate buydown. In today's market, a seller-paid buydown can lower your monthly payment and, with it, your front-end ratio.

The Bottom Line

Your debt-to-income ratio is not a pass-fail test you either survive or flunk. It is a dial. And the earlier you understand where yours sits, the more options you have to move it before you ever write an offer. I would much rather spend an hour with you now, mapping this out, than watch you fall for a home that turns out to be just past your reach.
