Curious—has anyone actually had luck getting a straight answer about how student loan payments factor into DTI? Or is it always just a “depends who you talk to” situation?
Honestly, it’s almost always a “depends who you talk to” thing in my experience. I’ve had lenders use 1% of the balance for federal loans, but then another guy insisted on using the actual payment—even if it was zero due to income-based repayment. Private loans seem to throw folks for a loop even more. It’s wild. I usually just prep clients for the worst-case scenario so there aren’t any surprises. The inconsistency drives me nuts, but I guess that’s just the game right now.
Title: Student Debt And Mortgages: Did You Know This Weird Connection?
Yeah, the inconsistency is wild. I’ve literally had underwriters on the same loan disagree about which number to use for DTI—one wanted the actual payment, the next day someone else insisted on 1% of the balance. It’s like a weird mortgage roulette. The private loan thing is even messier... half the time, nobody seems to know what to do with them. I wish there was a magic formula, but right now it feels like you just have to brace for whatever curveball they throw.
Yeah, the inconsistency is a real headache. Here’s what I’ve learned after going through this circus a couple times:
- Lenders don’t all play by the same rules. Some stick to Fannie Mae/Freddie Mac guidelines, others have overlays or their own quirks. It’s not just about the numbers—it’s about who’s looking at your file that day.
- For federal student loans, if you’re on an income-driven repayment plan, some underwriters will use your actual payment, but others default to 1% of the balance (or 0.5% for FHA). It’s wild how much your DTI can swing depending on which number they pick.
- Private loans are even more unpredictable. I had one lender count my full payment, another wanted to use a percentage of the balance because they “couldn’t verify” the payment amount—even though I sent in statements. It felt like they were just making it up as they went.
- If you’re in deferment or forbearance, most lenders won’t just ignore the debt. They’ll usually use 1% of the balance, even if you’re not paying anything right now.
A couple things that helped me:
- Get everything in writing from your loan servicer—payment amounts, terms, deferment status. The more documentation you have, the less wiggle room for underwriters to “interpret.”
- Ask your lender up front which guidelines they follow for student loans. Saves a lot of back-and-forth later.
- If you get conflicting info from different underwriters at the same company, don’t be afraid to escalate or ask for clarification. Sometimes it’s just a training issue.
Honestly, it’s frustrating how much this stuff can come down to luck or who’s working your file that day. I wish there was a universal standard, but until then... best you can do is be over-prepared and ready for curveballs. The process isn’t fair, but being organized definitely helps tilt things in your favor.

That really nails it. It’s wild how two people with the same numbers can get totally different answers depending on the underwriter. I’ve seen deals fall apart at the last minute because someone interpreted a student loan differently than expected. Your point about documentation is spot on—having every detail in writing can make all the difference. It’s not fair, but being meticulous is the only way to reduce surprises. Hang in there; being prepared does pay off, even if it feels like a slog sometimes.

No kidding. I thought I was all set until my lender suddenly decided to count my student loan payment differently than the pre-approval. Had to scramble for extra paperwork... Not sure if it’s luck or just chaos, honestly.
