Mortgage rates have been bouncing around the mid-6% range for months, and plenty of buyers assume the rate is what's killing their application.
Lenders can forgive a high rate if you can afford it.
What they rarely forgive is a debt-to-income ratio that doesn't add up on paper.
Your DTI is simple math: all your monthly debt payments divided by your gross monthly income.
If you bring in $6,000 a month and owe $300 on a car loan, $200 in minimum credit card payments, and $1,500 in rent, that's $2,000 divided by $6,000 — a 33% DTI before a mortgage even enters the picture.
Most conventional loans cap your total DTI at 43%, and many lenders get nervous above 36%.
FHA loans can stretch to roughly 50% with compensating factors, but that's the ceiling, not a target.
In a market where home prices are still elevated and insurance premiums have jumped in many states, a payment that looked comfortable two years ago can push you over the line.
The trap is that buyers obsess over the interest rate and ignore the denominator.
You can't control the Fed, but you can control what shows up in your monthly obligations.
Paying off a $4,000 credit card balance doesn't just save interest — it can wipe out a $100+ minimum payment and shave several points off your DTI overnight.
Watch for a few sneaky items lenders count that borrowers forget.
Student loan payments count, even ones in income-driven repayment plans, though some lenders use the actual payment rather than a percentage of the balance.
A co-signed loan for a family member absolutely counts, even if you never make a payment.
And a new car loan taken out mid-house-hunt can sink an already-approved application.
If you're close to the line, timing matters.
Lenders pull credit and re-verify debts late in the process, so don't finance furniture or a truck between pre-approval and closing.
Ask a loan officer to run your numbers before you fall in love with a house — most will do it for free, and knowing your ceiling beats guessing.
There's also a quiet workaround some buyers overlook: paying down a loan balance rather than closing the account.
Closing a credit card can hurt your credit score, while reducing the balance lowers the minimum payment and your DTI at the same time.
The takeaway is that your rate gets the headlines, but your ratio often decides the outcome.
Final Thoughts
Getting a straight answer on your DTI before you shop could save you months of rejected offers and wasted application fees.
