If you've been house-hunting this spring, you've probably memorized the interest rate dance.
But there's a quieter number doing more damage to your buying power, and it has nothing to do with the Fed.
It's your debt-to-income ratio, and the threshold lenders use to approve you has been creeping in the wrong direction.
Your DTI is all your monthly debt payments divided by your gross monthly income.
That includes your future mortgage payment, plus car loans, student loans, minimum credit card payments, and personal loans.
A 43% DTI has long been the rough ceiling for a qualified mortgage, but many lenders now want you closer to 36% — and some are getting stricter than that.
Home prices stayed stubbornly high even as rates climbed, so buyers are stretching further to afford less house.
When borrowers are already maxed out, one layoff or medical bill can tip a household into default.
Banks remember 2008, and they'd rather say no now than foreclose later.
The practical effect is ugly for first-time buyers.
Two years ago, a household earning $90,000 with a $400 car payment and modest student loans might have qualified for a $400,000 mortgage.
Today, the same family could get capped well below that, even though the monthly payment on that loan has also gone up.
You're being squeezed from both ends: higher rates and a tighter ratio.
The people who benefit are the ones paying cash, the ones with equity from a previous home, and the lenders themselves, who get to cherry-pick low-risk borrowers.
Everyone else gets told to pay down debt first, save more, and try again.
That's not necessarily bad advice, but it conveniently keeps demand — and prices — from falling as fast as buyers might hope.
Paying down revolving debt does more than saving the same amount, because credit cards carry high minimum payments that crush your ratio.
A $5,000 card balance might cost you $150 a month, which is a much bigger DTI hit than the same $5,000 sitting in a savings account.
Paying it off can sometimes unlock more borrowing room than the payment itself would suggest.
Also worth knowing: some lenders will allow higher DTIs if you have compensating factors — big cash reserves, a long history with the bank, or a co-borrower with strong credit.
It's not a hard wall everywhere, and rules vary by loan type.
FHA loans, for instance, have historically allowed higher ratios than conventional ones, though that comes with mortgage insurance costs.
The trap is assuming pre-approval equals affordability.
A lender's maximum is the most they think they can collect, not the most you can comfortably live with.
Stretch to the ceiling and you've got no room for a new roof, a car repair, or a raise that doesn't keep up with insurance and taxes.
The takeaway is simple: run your own numbers before a lender runs theirs.
Add up every minimum payment, be honest about income, and see where you actually land.
That's a number you control — at least more than you control rates.
Our take: the DTI squeeze is real, but it's also a useful reality check in a market that spent years encouraging people to borrow at their absolute limit.

Being house-poor for a decade stings more.
