Student debt and mortgages: Did you know this weird connection?

I’ve actually had a smaller local lender back down once after I emailed them the exact Fannie Mae guideline—they admitted they’d missed an update. With the big banks, though, it’s like you’re talking to a brick wall most of the time. Ever notice how they’ll just repeat their “policy” no matter what you show them? It’s frustrating, but you’re right—having documentation ready is still worth it. Sometimes it surprises you who’ll actually listen.

It’s wild how different lenders can be, right? I once had a big-name bank insist my student loan payment had to be calculated a certain way, even though I pulled up the updated Freddie Mac guideline right there. Didn’t matter—they just kept repeating, “That’s our policy.” I half expected them to start quoting Shakespeare next. Ever feel like you need a decoder ring just to talk to these folks? I swear, sometimes it’s like arguing with a chatbot... but at least a chatbot might update itself.

Totally get what you mean. I had a client who got three different answers from three different lenders about how her student loans would impact her DTI. One guy even told her, “We just don’t count those,” which sounded... off. It’s wild how much policies can vary, even when the guidelines are right there in black and white. Sometimes I wonder if they’re just making it up as they go along.

It’s honestly kind of nuts how inconsistent the info is, especially when you’re trying to make such a huge financial decision. I ran into something similar last year when I was shopping for my first place. One lender told me they’d use 1% of my student loan balance for DTI calculations, another said they’d go by the actual payment on my credit report, and a third just shrugged and said “depends on the underwriter.” Super reassuring, right?

What really bothers me is there’s supposed to be federal guidelines—like Fannie Mae and FHA both have published rules about student loans and DTI—but the interpretation seems to change depending on who you talk to. It almost feels like some lenders are either not up-to-date or just hoping you won’t notice. Maybe it’s just poor training, but sometimes it comes off as shady.

Here’s what I ended up doing: I asked each lender to show me in writing exactly how they’d calculate my DTI with my loans. Not everyone was willing, which honestly made my decision easier. If someone can’t be transparent about their own process, that’s a red flag for me.

I get that policies shift (and sometimes mid-process), but if you’re making a budget or trying to figure out how much house you can afford, those little calculation differences can mean thousands of dollars in what you qualify for—or don’t. It gets even trickier if your loans are in deferment or income-driven repayment, because then it’s a guessing game unless the lender actually knows what they’re doing.

Honestly, I wish there was more accountability here. At minimum, lenders should have to stick to clear guidelines instead of playing fast and loose with people’s finances. It shouldn’t take a spreadsheet and hours of research just to get a straight answer... but here we are.

If nothing else, double-check everything they tell you and don’t be afraid to walk away if something doesn’t add up. Your future self will thank you for being picky now.

- 100% agree on the “depends on the underwriter” thing—like, is there a secret handshake I missed?
