The Income, Credit, and Debt Framework: How to Know If You're Really Ready to Buy?
People ask me some version of this question almost every week: "Am I actually ready to buy a house, or am I just tired of renting?"
Those are two very different questions, and I've spent twelve years building a way to help you tell them apart. I call it the income, credit, and debt framework. It's not complicated. It's not a formula I hand you and walk away from. It's the same three conversations I have with every single client, first-time buyer or fifth-time buyer, before we ever look at a home. Let's walk through it together.
Piece one: income
Lenders don't just want to know what you make. They want to see that it's stable and that they can document it. If you're a W-2 employee, this part is usually simple. If you're self-employed or have variable income, plan on providing two years of tax returns, and let's talk early so nothing catches you by surprise later.
There's no single income number required to qualify for a mortgage. What matters more is the relationship between what you make and what you already owe, which brings us to the next piece.
Piece two: debt (and the ratio that runs the whole show)
This is the number that quietly decides more than almost anything else: your debt-to-income ratio, or DTI. It's simply your monthly debt payments (car loan, student loans, credit cards, and your future mortgage payment) divided by your gross monthly income.
Here's how lenders typically look at it:
Conventional loans: Lenders generally like to see DTI at 36% or below, though it's possible to qualify up to 45%, and in some cases as high as 50%, if you have strong compensating factors like a larger down payment, a higher credit score, or solid cash reserves.
FHA loans: Typically capped around 43%, with some flexibility for stronger credit profiles.
VA and USDA loans: Generally capped around 41%.
Let's make that real. Say you bring home $6,000 a month before taxes, and you're paying $300 for a car and $200 in minimum credit card payments. If your future mortgage payment would be $1,900 a month, your total monthly debt is $2,400. Divide that by $6,000, and your DTI is 40%. That's within FHA territory and likely within reach for a conventional loan too, depending on the rest of your file.
This is exactly the kind of math I sit down and do with clients, on paper, in a real conversation. Not a black box. Not a guess.
Piece three: credit
Your credit score isn't a verdict on your character. It's a snapshot of how you've handled debt so far, and it changes faster than most people realize. Here's what the different loan types actually require:
Conventional loans generally want to see a credit score of at least 620.
FHA loans are more forgiving: a 580 score qualifies you for the standard 3.5% down payment, and scores as low as 500 can still qualify with 10% down.
The higher your score climbs above these minimums, the better your interest rate is likely to be, which affects your monthly payment far more than most people expect.
I've watched clients move from the low 600s into pre-approval range in a matter of months, not by doing anything dramatic, just by paying down a couple of specific balances and correcting an error on their report. It's rarely magic. It's usually a plan.
Putting the three pieces together
For 2026, the baseline conforming loan limit (the ceiling for what Fannie Mae and Freddie Mac will back on a standard loan) is $832,750 in most of the country, including here in the DFW area. FHA's loan limit in lower-cost areas sits at $541,287 for 2026. These numbers matter because they tell you what's actually financeable before you fall in love with a listing outside your range.
And here's the number that surprises almost everyone: according to the National Association of REALTORS' 2025 Profile of Home Buyers and Sellers, the median down payment for first-time buyers was 10%, not the 20% so many people assume they need. Down payment assistance can often close that gap even further, which is exactly what we'll cover in a future post.
The real point of this framework
Fear and confusion kill more home purchases than bad markets ever do. When you actually understand your income, your credit, and your debt, together, in real numbers, "ready" stops being a feeling and becomes a plan you can act on.
If you want to walk through your own numbers together, that's exactly the conversation I love having. Let's start it.
