I hear a version of this same worry almost every week. Someone reaches out convinced their student loans have quietly disqualified them from ever owning a home. Usually they have not even applied yet. They just assumed.
Here is the truth. Student loan debt does not close the door on a mortgage. It just changes the math a little, and once you understand the math, it stops being scary.
How lenders actually count your student loan payment
Your student loan shows up in one place, your debt to income ratio, also called DTI. Lenders add up all your monthly debt payments, including your student loan, and divide that by your gross monthly income. Most conventional loans want that number under 43 to 45 percent, though some programs allow more.
The tricky part is how your student loan payment gets calculated if you are on an income driven repayment plan. If your loan servicer reports a $0 or very low monthly payment, many lenders cannot simply use that $0 in their math. Depending on the loan type, they may use 1 percent of your total loan balance as your assumed payment instead, or pull the actual amount from your credit report.
So someone with $60,000 in student loans on an income driven plan might see a lender assume a $600 monthly payment even though their real payment is much lower. That single detail is what surprises people the most, and it is worth asking your loan officer about early, before you fall in love with a house.
What actually improves your odds
A few things matter more than the loan balance itself.
Your payment history matters. On time payments for the last 12 months carry real weight with underwriters.
Your income relative to that adjusted payment matters more than the total balance. A $40,000 balance on a $150,000 income looks completely different than the same balance on a $50,000 income.
Your other debt matters. If your student loan is your only debt besides a car payment, you have far more room than someone juggling credit cards on top of loans.
A quick real world example
Say your gross monthly income is $6,500. Your student loan payment, however the lender calculates it, comes out to $350. Your car payment is $400. That is $750 in debt before you even add a mortgage. At a 43 percent DTI ceiling, your total allowed debt payments are about $2,795. Subtract the $750 already spoken for, and you have roughly $2,045 left for a full mortgage payment including taxes and insurance. That is enough for a meaningful home price in most markets, student loans and all.

Your DTI is elevated. You may still qualify but with fewer lender options.
Your 14.4% down payment triggers PMI. At your credit score (Good (670–739)) and 85.6% LTV, PMI costs approximately $103/month ($1238/year).
How to eliminate PMI:
Putting down $55,600 (20%) eliminates PMI and saves $1238/year.
