The short version
Quick answer: Buying a house with student loan debt is almost never a credit problem. It is a debt-to-income problem. The payment that lands in your ratio is often not the payment you actually make. FHA and Freddie Mac use 0.5 percent of your balance when the credit report shows zero. Fannie Mae uses 1 percent for a deferred loan, but will accept a documented zero-dollar income-driven payment as zero. VA uses 5 percent of the balance divided by 12. It ignores the debt entirely when deferment runs at least 12 months past closing. Same borrower, same debt, four different numbers.
Most people with student loans assume the problem is their score. It usually is not. Scores recover, and a loan in good standing helps one. The thing that quietly decides the file is a single line an underwriter types into a ratio. A rulebook sets that line, and it is one you did not choose and probably have not read.
Here is the part that surprises people. Your servicer can bill you nothing this month and a lender can still count hundreds of dollars against you. Or the reverse. Which one happens depends on the program, not on your budget. So this page lays out the four rules side by side. Then it works the arithmetic in front of you on one balance. Finally it translates the gap into the only unit that matters, which is how much house you can finance.
Key takeaways
- A zero-dollar bill is not automatically a zero-dollar debt. Freddie Mac says it plainly: an amount greater than zero must be included for all student loans. FHA agrees. Fannie Mae is the one program that will take a documented zero.
- On a 42,000 dollar balance the four rules produce 0, 175, 210 and 420 dollars. That is a 420 dollar spread on identical debt, and nothing about the borrower changed between those numbers.
- The multiplier is the whole game. FHA and Freddie use 0.5 percent of the balance. Fannie uses 1 percent when the loan is deferred. VA uses 5 percent divided by 12, which lands near 0.42 percent a month.
- VA is the outlier in both directions. Deferred at least 12 months past closing and documented, the payment does not get counted at all. In repayment, VA uses its own formula rather than your bill.
- Forgiveness can remove the debt from the ratio, but only with paperwork. FHA and Freddie both allow an exclusion when the file documents that the balance is being forgiven, canceled or discharged.
How does a student loan payment get into your ratio?
Your debt-to-income ratio is a fraction. On the bottom sits your gross monthly income. On the top sits every monthly obligation the lender must count, including the housing payment you are applying for. Student loans go on top.
But student loans are different. They are the one common debt where the amount billed and the amount counted routinely disagree. A car payment is a car payment. A minimum credit card payment comes straight off the report. A student loan, though, can sit in deferment, in forbearance, or on an income-driven plan that bills you nothing. Every agency has written its own instruction for that case.
So the rule is not "use what you pay." The rule is "use what this rulebook says," and there are four rulebooks in ordinary use. An FHA file follows HUD Handbook 4000.1, which is the rulebook behind where an FHA purchase in Clark County begins. A conventional file follows either the Fannie Mae Selling Guide or the Freddie Mac Seller/Servicer Guide. Which one depends on where the loan is being sold. A VA file follows VA Pamphlet 26-7. They do not agree with each other, and none of them is trying to.
Read this first The number in your ratio is a program output, not a fact about your life. Two lenders looking at the same credit report can honestly arrive at different payments, because they are reading different books. That is not a mistake and it is not anyone being difficult.
What are the four rules, side by side?
Every figure below was read from the current published source, and the revision dates are given because these rules change. Here is what each program does with a student loan.
| Program | Payment reported above zero | Payment reported as zero | Can it be excluded? |
|---|---|---|---|
| FHA | Use the credit report payment or the actual documented payment | 0.5 percent of the outstanding balance | Yes, with documentation that the balance is forgiven, canceled, discharged or paid in full |
| Fannie Mae | Use the credit report payment, or the payment on the most recent statement | Documented income-driven zero may be used as zero. Deferred or in forbearance: 1 percent of balance, or a documented fully amortizing payment | Not as a general rule |
| Freddie Mac | Use the credit report payment | 0.5 percent of the outstanding balance. An amount greater than zero must always be included | Yes, for documented forgiveness, cancelation, discharge or employment-contingent programs, with limits |
| VA | Use the credit report payment when it exceeds the formula | 5 percent of the balance divided by 12 | Yes, when written evidence shows deferment at least 12 months beyond closing |
Look at the third column. Three of the four programs refuse to let a zero stay a zero. The one that allows it still wants servicer documentation proving the payment really is zero under an income-driven plan.
What happens when the credit report says zero?
This is where most of the damage happens, and it is worth being precise about why. An income-driven repayment plan can genuinely set your payment at zero dollars. That is a real, lawful, current obligation of nothing. Your servicer agrees. Your credit report says so.
Then FHA turns that zero into 0.5 percent of the balance, and so does Freddie Mac. Freddie is unusually blunt about it. In all cases, it says, an amount greater than zero must be included for all student loans. The logic is that the zero is temporary. Underwriting is a bet on a 30 year obligation. So the agencies substitute a placeholder for a payment they expect to reappear.
Fannie Mae is the exception, and the distinction inside its own rule is the one people miss. Fannie treats an income-driven zero differently from a deferment. Are you on an income-driven plan, with paper proving the payment is genuinely zero? Then the lender may qualify you at zero. If the loan is merely deferred or in forbearance, Fannie uses 1 percent of the balance. That is double what FHA and Freddie use.
So the same borrower can land better off under Fannie than under FHA, or considerably worse off. The deciding fact is a status word on a servicer statement.
The multipliers, converted so they compare
The four rules are quoted in different units, which hides how they rank. Converted to a monthly percentage of the balance, they line up like this.
| Rule | As published | Monthly percent of balance | On a 42,000 dollar balance |
|---|---|---|---|
| Fannie Mae, documented income-driven zero | Use zero | 0 percent | 0 dollars |
| VA, in repayment | 5 percent divided by 12 | About 0.4167 percent | 175 dollars |
| FHA, zero reported | 0.5 percent | 0.5 percent | 210 dollars |
| Freddie Mac, zero reported | 0.5 percent | 0.5 percent | 210 dollars |
| Fannie Mae, deferred or forbearance | 1 percent | 1 percent | 420 dollars |
The arithmetic, worked. Balance of 42,000 dollars, credit report showing a zero payment.
FHA and Freddie Mac: 42,000 times 0.005 equals 210 dollars. Fannie Mae on a deferred loan: 42,000 times 0.01 equals 420 dollars. VA in repayment: 42,000 times 0.05 equals 2,100, divided by 12 equals 175 dollars. Fannie Mae with a documented income-driven zero: 0 dollars.
The distance between the highest and lowest figure is 420 dollars a month. The borrower is the same person in all four rows.

Get your fast quoteHow much house does the difference actually buy?
A 420 dollar spread sounds abstract. Here it is converted into borrowing capacity on one illustrative file.
Assume 7,000 dollars of gross monthly income. Assume 2,450 dollars of other monthly obligations, a figure that already includes the housing payment being applied for. Those numbers are assumptions chosen so the arithmetic can be checked, not a quote and not terms available to anyone.
| Qualifying student payment | Total obligations | Ratio at 7,000 dollars income |
|---|---|---|
| 0 dollars | 2,450 dollars | 35.00 percent |
| 175 dollars | 2,625 dollars | 37.50 percent |
| 210 dollars | 2,660 dollars | 38.00 percent |
| 420 dollars | 2,870 dollars | 41.00 percent |
Now run it the other way, which is the version that actually changes what you shop for. Suppose the ceiling on this file is 43 percent. That allows 3,010 dollars of total obligations, because 0.43 times 7,000 equals 3,010. Subtract a 420 dollar student payment and 2,590 dollars remain for everything else. Subtract nothing and 3,010 dollars remain.
That 420 dollar gap is housing payment. It is not a rounding difference and it is not negotiable at the closing table. It was decided the moment somebody chose which rulebook your file would be underwritten to.
What does this mean for a Las Vegas buyer?
Two Clark County facts turn the general rule into a specific decision, and both come straight from the agencies.
The first is the ceiling on each program. For calendar year 2026 the FHA forward limit for a one-family home in Clark County is 541,287 dollars. The conforming limit that Fannie Mae and Freddie Mac work to is 832,750 dollars. HUD publishes both figures on the same lookup. The median sale price it used for Clark County is 462,000 dollars.
| Program | One-family limit | Two-family | Four-family |
|---|---|---|---|
| FHA forward | 541,287 dollars | 693,050 dollars | 1,041,125 dollars |
| Fannie Mae and Freddie Mac | 832,750 dollars | 1,066,250 dollars | 1,601,750 dollars |
Here is the thing worth knowing that a national page will not tell you. All 17 Nevada jurisdictions sit at the baseline conforming limit, which is 16 counties plus Carson City. No high-cost tier exists anywhere in the state. So Las Vegas has no intermediate rung between conforming and jumbo. Cross 832,750 dollars on a one-family home and you have left the agency rulebooks entirely. You have left the four student loan rules on this page behind too.
The second fact is a VA one, and it matters because of Nellis Air Force Base. VA does not rely on the ratio the way the other programs do. Its real test is residual income, the money left over each month after the housing payment, the counted debts and taxes. VA sorts that requirement by region and family size. Nevada sits in VA's West region, alongside Arizona, California and ten other states.
| Family size | Required monthly residual income |
|---|---|
| 1 | 491 dollars |
| 2 | 823 dollars |
| 3 | 990 dollars |
| 4 | 1,117 dollars |
| 5 | 1,158 dollars |
Above a family of five, VA adds 80 dollars for each additional member up to seven. Residual income is a dollar test rather than a percentage test. So a VA file can survive a ratio above 41 percent when the leftover money is strong. The VA formula produced the second-lowest figure in our table. In practice it tends to be gentler still, for exactly that reason.
Can a loan being forgiven be left out?
Sometimes, and this is the most underused rule of the four.
FHA allows the payment to be excluded from the ratio in one situation. Written documentation from the student loan program, the creditor or the servicer must indicate that the balance has been forgiven, canceled, discharged or otherwise paid in full. Freddie Mac allows an exclusion too, and spells out the conditions more tightly. The file must document that the borrower is eligible or approved for the forgiveness, cancelation, discharge or employment-contingent program. Then it must show one of two things. Either 10 or fewer monthly payments remain until the balance is forgiven. Or the loan is deferred or in forbearance, and the full balance will be forgiven when that period ends.
The practical reading is straightforward. Being on a forgiveness track is not enough by itself. Being near the end of one is different. With paper from the program or the employer, the debt can leave the ratio completely. If you are close, that timing is worth knowing before you write an offer rather than after.
A boundary worth stating This is a mortgage qualifying article. Nothing here is advice about changing your repayment plan. Switching plans to chase a lower qualifying payment can cost far more in interest than it gains in buying power. Talk to your servicer about the loan itself.
What can you do before you apply?
Four moves, in the order they pay off.
- Pull your own credit report and read the student loan line. The payment shown there is the starting point for three of the four rules. If it is wrong, it is fixable, and it is much easier to fix before an application than during one.
- Get a current statement from your servicer. Fannie needs it to accept a zero. FHA needs it when the payment used is lower than the reported one. VA needs one dated within 60 days of closing to count a payment below its formula.
- Know your status word. Deferment, forbearance and income-driven repayment are three different things to an underwriter. Under Fannie Mae, the last two are the difference between 420 dollars and zero on our example balance.
- Ask for the ratio under more than one program before you shop. The comparison takes minutes and it can move the price range you are looking at.
The decision rule, in one line
If your credit report shows a real payment, all four programs are close and the choice turns on other things. If it shows zero, the ranking is fixed. A documented income-driven zero favors Fannie Mae. A deferred loan penalizes Fannie Mae most. FHA and Freddie land in the middle at half a percent.
The messy cases nobody explains
| Situation | What actually happens |
|---|---|
| Your income-driven payment recertifies soon | Freddie Mac will not let you use the current low payment if the file shows you must recertify on or before the first mortgage payment due date, or that the payment will rise. It uses the greater of the current payment or 0.5 percent instead. |
| A parent is paying your loans | Freddie Mac treats payments made by another party as a contingent liability question, and names multiple student loans paid by a parent as a common example. Documentation of 12 months of timely payments by that party is the hinge. |
| The loan is deferred well past closing and you are using VA | Written evidence of deferment at least 12 months beyond closing means no payment is counted at all. No other program on this page offers that. |
| Your servicer shows a payment lower than the formula | VA will use it, but only with a servicer statement dated within 60 days of closing. FHA asks for written documentation of the actual payment, status, balance and terms. |
| You are buying above the conforming limit | Above 832,750 dollars on a one-family Clark County home you are outside the agency rulebooks, and the qualifying rules become whatever that program sets. |
One caution about older guidance
These rules changed, and stale copies of them are still easy to find. An earlier edition of HUD's handbook told lenders to use the greater of 1 percent of the balance or the reported payment. It carried no separate instruction for a zero. That is not the current rule, and a page repeating it will overstate your payment by double. Always check the revision date on whatever you are reading, including this page.
Student loans and mortgages: FAQ
The basics
Do student loans stop you from buying a house?
No. They reduce how much you can borrow, because the qualifying payment sits in your debt-to-income ratio. A student loan in good standing also builds the payment history a mortgage file wants to see. So the debt cuts both ways.
Does paying my student loan off help more than paying down other debt?
Not usually, and the arithmetic explains why. Three of the four programs count a percentage of your balance rather than your bill. So paying a balance down lowers the counted payment proportionally. A credit card is different. It can often be cleared entirely for less money, and that removes its whole payment from the ratio.
The zero-payment question
My income-driven payment is zero dollars. Will a lender count it as zero?
Only under Fannie Mae, and only if you document it. Fannie lets the lender obtain documentation verifying the actual monthly payment is zero. It may then qualify you at zero. FHA and Freddie Mac both substitute 0.5 percent of the balance when the credit report shows zero.
Why is a deferred loan treated worse than an income-driven one under Fannie Mae?
Because deferment ends on a schedule, and nobody knows what the payment will be afterward. So Fannie applies 1 percent of the balance for deferred loans and loans in forbearance. A fully amortizing payment from documented terms is the alternative. An income-driven payment, by contrast, is a real current amount the servicer can verify.
Program by program
What percentage does FHA use for student loans?
FHA uses the payment reported on the credit report or the actual documented payment when that amount is above zero. When the reported payment is zero, it uses 0.5 percent of the outstanding balance. The rule appears identically in the TOTAL scorecard and manual underwriting sections of HUD Handbook 4000.1.
How does VA calculate a student loan payment?
VA takes 5 percent of the outstanding balance and divides it by 12. On the handbook's own example, a 25,000 dollar balance produces 1,250 dollars. Divided by 12, that equals 104.17 dollars a month. If the credit report payment is higher than that figure, the lender uses the credit report instead.
Does VA ever ignore student loan debt completely?
Yes. Provide written evidence that the debt will be deferred at least 12 months beyond closing. Then no monthly payment needs to be considered. That exclusion is unique to VA among the four programs covered here.
Local questions
What are the 2026 loan limits in Clark County?
For a one-family home, the FHA forward limit is 541,287 dollars and the conforming limit is 832,750 dollars. Both figures come from HUD's own mortgage limits lookup for calendar year 2026. The conforming figure matches the FHFA county file exactly.
Does Nevada have any high-cost counties for conforming loans?
No. All 17 Nevada jurisdictions, meaning the 16 counties plus Carson City, sit at the 832,750 dollar baseline for a one-family home in 2026. So Las Vegas has no high-balance tier between conforming and jumbo. That is unusual for a metro of its size.
How much residual income does VA require in Nevada?
Nevada is in VA's West region. On loan amounts of 80,000 dollars and above, the requirement runs from 491 dollars for a household of one to 1,117 dollars for a household of four, and 1,158 dollars for a household of five. Above five, VA adds 80 dollars per additional member, up to a household of seven. So a household of seven needs 1,318 dollars.
The bottom line
Student debt does not decide whether you can buy. It decides how much, and it does that through a number you did not pick and can partly control. Find out what your credit report says. Get a statement from your servicer. Then ask for the ratio under more than one program, before you fall in love with a house. The four rules are public and written down. On a typical balance, the gap between the best and worst of them is worth a decent monthly housing upgrade.
The Valley West take Borrowers usually arrive convinced the student loan is a credit problem and leave surprised it was an arithmetic problem. Two habits fix most of it. First, pull the credit report yourself and read the student loan line before anyone runs a ratio. Three of the four rules start from that line, and a wrong one costs real money. Second, ask what your qualifying payment would be under each program rather than accepting the first figure you hear. Valley West Mortgage is an independent mortgage lender, NMLS #65506. Every rule and figure here is cited so you can check it rather than take it on trust.

All 17 Nevada jurisdictions, the 16 counties plus Carson City, appear at the baseline.
Article history
- September 5, 2026. First published. Every source above was fetched live on this date. The FHA rule came out of the current Update 18 handbook rather than a summary page. The Freddie Mac section had to be read on its rendered page, because the printable version returns an empty shell. The VA chapter came from VA's KnowVA article rather than the retired WARMS library. Every percentage, ratio and dollar figure on the page was recomputed by hand.
What the fact check changed, same day
- September 5, 2026, a VA figure corrected. The residual income increment for households above five was published as 75 dollars and is 80 dollars. VA prints two residual tables, one for loan amounts of 79,999 dollars and below and one for 80,000 dollars and above, and each carries its own increment. The first version took the increment from the first table while taking its five dollar figures from the second. The five figures were right. The increment was one table out, and it understated what VA requires of a large household, so it was corrected in the body, in the FAQ and in the page's FAQ schema together.
- September 5, 2026, a state count corrected. VA's West region holds 13 states. Naming Nevada plus two of them leaves ten others, not nine.
- September 5, 2026, a noun corrected. The 17 Nevada jurisdictions at the baseline conforming limit are 16 counties plus Carson City, which is an independent city. The substance, that no Nevada jurisdiction is high-cost, was verified and is unchanged.
- September 5, 2026, a deferment threshold tightened. Two summary lines read "more than 12 months" where VA's text reads "at least 12 months beyond the date of closing". The table and the FAQ already carried it correctly.
- September 5, 2026, the wrong enquiry form replaced. The form at the foot of this page was built from a template whose copy described a rental rent-schedule review. That is a different product and it promised a reader of this page something this page is not about, so it was rewritten to describe the student loan question instead.
- September 5, 2026, the reading time corrected. The byline said 11 minutes for a 4,900 word article, which implies a reading speed no one has. It now says 20.
What the build refused
- September 5, 2026, a stale handbook rejected. The older HUD handbook file still served at hud.gov returns a valid seven megabyte PDF and reads as authoritative. It is the August 14, 2019 transmittal. Its student loan section still carries the superseded instruction to use the greater of 1 percent of the balance or the reported payment. Citing it would have doubled the FHA figure on this page. The current Update 18 handbook is cited instead, and the difference is called out in the article itself.
- September 5, 2026, no rate quoted. Every dollar figure on this page is an assumption chosen so the arithmetic can be verified. No interest rate, annual percentage rate or loan term appears anywhere. None of the tables describes terms available to any applicant.
- September 5, 2026, repayment-plan advice left out. Switching student loan repayment plans can change the qualifying payment. It can also cost more in interest than it gains in buying power. The page states the rules and stops there rather than counseling a plan change.
