Student Loans and Buying a House in San Diego: How Your Payment Actually Gets Counted

7 minute read · For San Diego buyers carrying federal student loans — especially anyone who was on SAVE.

The short version

• A $0 student loan payment is not the same as $0 student loan debt on a mortgage application. Several programs will invent a payment for you.
• Every major loan program counts student loans differently, and the spread is enormous. On the same $80,000 balance, one program may count $0 and another may count $333 a month.
• SAVE ended after a March 10, 2026 court order. The new Repayment Assistance Plan (RAP) took effect July 1, 2026, and servicers began notifying former SAVE borrowers that same month with a 90-day window to choose a plan. For the first wave of notices, that window closes right about now.
• Whatever payment you land on is the number a lender is going to see on your credit report. Picking a repayment plan in September is, functionally, a mortgage decision.
• Freddie Mac’s national average 30-year fixed rate was 6.76% in the survey released September 10, 2026 — up from 6.71% the prior week, and 6.35% a year ago.

The thing almost everyone gets wrong

I have had a version of this conversation probably two hundred times: someone tells me their student loan payment is zero, so it should not affect anything.

I understand why that feels obviously true. Nothing leaves your checking account. Your budget does not feel it. And yet on a mortgage file, a $0 payment is one of the more expensive things you can bring to the table, because most loan programs refuse to believe it. They substitute a percentage of your outstanding balance instead — and the percentage they pick is not small.

In San Diego this matters more than it does almost anywhere else. When the purchase price is high, the housing payment eats most of the debt-to-income ratio before any other debt shows up. A phantom $400 student loan payment that would be an annoyance in Ohio can be the entire reason a San Diego file does not work.

Why this is a September problem and not a someday problem

The SAVE plan is over. It ended following a March 10, 2026 court order, and the Repayment Assistance Plan — RAP — went into effect on July 1, 2026. Starting that month, servicers began sending former SAVE borrowers notice that they had 90 days to choose a new repayment plan or be moved into one automatically.

Count forward from July and you land in late September and early October. Millions of people are about to have a new monthly student loan payment for the first time in years, and most of them are choosing a plan based on cash flow alone.

That is a reasonable way to choose. It is just incomplete. The plan you pick determines the number that shows up on your credit report, and that number walks into every mortgage conversation you have for the next several years. If buying is anywhere on your horizon — this year, next year — it is worth running the comparison before the automatic enrollment picks for you.

How each program counts it

Here is the part nobody explains clearly. These are the general agency rules as they stand in 2026. Individual lenders layer their own overlays on top, and documentation requirements vary, so treat this as the map and not the territory.

Loan type	If your credit report shows a real payment	If it shows $0	On an $80,000 balance
Conventional (Fannie Mae)	Uses the actual payment	Can use $0 on an income-driven plan, with documentation proving the payment really is $0. Deferment or forbearance instead: 1% of the balance.	$0 — or $800 if deferred
Conventional (Freddie Mac)	Uses the actual payment	0.5% of the outstanding balance	$400
FHA	Uses the actual payment	0.5% of the outstanding balance	$400
VA	Generally the greater of the credit report payment or 5% of the balance divided by 12	5% of the balance divided by 12	$333

Read that table twice, because there are two genuinely counterintuitive things in it.

First: Fannie Mae and Freddie Mac are both “conventional,” and they land in completely different places on the same borrower. A file that will not work one way may work the other way with no change to your income, your down payment, or the house. That is not a loophole; it is just two different rulebooks that happen to share a category name.

Second, and this is the San Diego one: VA is the least forgiving of the four on student debt. In a county with this much military and veteran population, that surprises people every single time. The benefit is extraordinary in almost every other respect — but on student loans specifically, 5% of the balance divided by 12 is a heavier assumption than FHA’s 0.5% or a documented income-driven payment on a conventional loan.

What actually moves the number

Three things, in rough order of how often they matter:

1. Documentation, not the credit report alone. A credit report showing $0 is frequently not enough on its own. What carries weight is current documentation from the servicer — a statement or repayment schedule showing the actual required monthly amount. People lose deals over a missing PDF far more often than over a real debt problem.
2. Deferment and forbearance are the expensive statuses. Pausing payments feels like relief. On a mortgage file it triggers the highest assumed payment in most programs. If you are pausing payments specifically to look better on a loan application, that is backwards.
3. Which program you use. Given the table above, the same file can be comfortable or impossible depending on the rulebook. This is the single largest lever, and it is usually the one nobody checks.

When NOT to reshuffle your student loans

I would rather say this plainly than let anyone read the section above as a strategy guide.

Do not switch repayment plans purely to manufacture a lower number on a mortgage application. Repayment plans carry consequences far beyond the next twelve months — total interest paid, forgiveness timelines, whether payments count toward Public Service Loan Forgiveness. A plan that shaves $150 off a debt-to-income calculation and costs you years of qualifying PSLF payments is a terrible trade, and no house is worth it.

Do not consolidate in a hurry either. Consolidation can reset progress toward forgiveness. If you have any PSLF history at all, talk to your servicer or a student loan specialist before touching anything. That is their expertise, not mine, and I will say so every time.

And do not let a student loan balance talk you out of even running the numbers. The number of people I meet who assumed they were years away and were not is genuinely high. Assuming is expensive in both directions.

A sensible order of operations

1. Log into your servicer and find out, in writing, what your required monthly payment is today and what it becomes under each plan available to you.
2. Pull your own credit and look at what the student loan tradelines actually say. Balance, status, reported payment.
3. Have someone run the debt-to-income math under more than one program before you decide anything — including the plan you enroll in.
4. Then choose your repayment plan, with the housing math as one input among several rather than an afterthought.

That is the whole sequence. It takes an afternoon and it routinely changes the answer.

Common questions

My loans are in deferment for another two years. Do they still count?

In most cases yes — and deferment usually produces the highest assumed payment, not the lowest. FHA uses 0.5% of the balance. Fannie Mae uses 1% when the loan is deferred or in forbearance. Being in deferment does not make the debt disappear from the calculation.

Does RAP help or hurt my debt-to-income ratio?

It depends entirely on your income and balance, which is an unsatisfying answer but an honest one. RAP produces a required monthly payment like any other plan, and that payment is what a lender will use where the program accepts a documented income-driven payment. The right move is to get the actual RAP figure from your servicer rather than estimating it.

If my spouse has the student loans and I do not, can we leave them off?

Only if your spouse is not on the loan application, and California being a community property state adds wrinkles depending on the program. Sometimes a one-borrower application is the cleanest path; sometimes it costs you the income you needed. It is worth modeling both ways rather than guessing.

Should I pay the balance down before applying?

Sometimes, and the math is sharper than people expect. On programs that assume a percentage of the balance, reducing the balance directly reduces the assumed payment — which can be far more efficient per dollar than the same money going toward a down payment. On programs that use your documented payment instead, paying down principal may not move the qualifying number at all. Same dollars, opposite outcomes, depending on the rulebook.

Where this fits

Student loans are one obstacle inside a much larger process. If you are earlier in the journey, start with the complete 2026 guide to buying a house in San Diego, which walks the whole sequence start to finish. For the payment side of the equation, the real monthly math on affordability is the companion piece, and how much down payment you actually need covers the other half of the cash question.
