Can I Use Social Security or Retirement Income to Buy a House?
By Jeff Moran, NMLS #483943 · August 27, 2026
The short answer: yes, and your income may count for more than the amount that hits your bank account. Social Security, some pension and disability payments, and certain other benefits are frequently non-taxable. Because a mortgage calculation compares gross income against your obligations, and non-taxable money never gets taxed, guidelines generally allow it to be grossed up — counted at a figure higher than the deposit itself.
Almost nobody on fixed income knows this. The result is a steady stream of people who assume retirement ended their buying power, shop far below what their file supports, or never ask at all.
There is a second thing worth saying plainly, because people worry about it and rarely ask: a lender may not decline you, or discount your income, because of your age. That is federal law, not a courtesy. There is no maximum age for a thirty-year mortgage.
I'm Jeff Moran, a mortgage broker in Bluffton, South Carolina, originating since 1996. In the Lowcountry this is one of the most common conversations I have, and it is one of the few where the news is usually better than expected.
Why non-taxable income counts for more
The logic is simpler than it sounds.
Qualifying compares your gross income — before tax — against the payments you owe. A salaried client earning $5,000 a month gross does not actually receive $5,000; taxes come out first. The calculation knows that and prices it in across the board.
Non-taxable income breaks that assumption in your favor. If $3,000 of Social Security arrives and none of it is taxed, you have more spendable money than someone with $3,000 of taxable wages. Counting both at $3,000 would understate you.
So guidelines allow non-taxable income to be increased by a set percentage before it enters the calculation. The percentage varies by loan program, and I am deliberately not printing it here — those figures get revised, and a number that is right today and wrong in two years is worse than no number. The tools price it against your actual scenario with current figures.
What matters is the shape: the income used in the calculation can be meaningfully larger than the deposit in your account. That is the part people do not know to ask about.
What generally qualifies for this treatment
Income that is genuinely not taxed. Depending on the situation, that can include Social Security, certain disability payments, some portions of pension and retirement income, certain VA benefits, and some child support.
The key word is genuinely. If a portion of your Social Security is taxable — which depends on your total income — then only the untaxed portion gets the treatment. Your tax returns settle it, which is one of several reasons returns get requested even when nobody is self-employed.
Continuance, which is the real test
Every kind of income in a mortgage file faces the same question: is it active, and will it continue? For retirement income the answer is usually straightforward, and the exceptions are worth knowing.
Social Security retirement benefits do not expire. Continuance is generally not a concern.
Disability benefits sometimes carry a defined review or end date. If the award letter states one, that matters, and the documentation needs to speak to it.
Pension income is normally durable, and a pension with a stated term rather than a lifetime benefit is treated according to that term.
Retirement account distributions — drawing from a 401(k) or IRA — can sometimes be used, generally where there is a documented history of taking them and enough remaining assets to support them continuing. This one has more moving parts than the others and is worth a specific conversation rather than a general rule.
Documentation is usually undramatic: an award letter, a 1099, and bank statements showing the deposits arriving. It is the same evidence-and-continuance test that governs variable income like overtime and bonuses, applied to a far more predictable kind of money.
The age question, answered directly
Federal law — the Equal Credit Opportunity Act — prohibits discriminating against a credit applicant on the basis of age. A lender may not decline you for being seventy-five, and may not discount income because of how old you are.
There is no rule that a thirty-year mortgage must be repaid within your lifetime. That idea circulates constantly and it is not how any of this works. What underwriting looks at is whether the income continues, not how long the client does.
If anyone tells you otherwise, that is worth a second opinion.
What I see go wrong
- Not asking about grossing up. Far and away the most common, and the most costly. People shop from their deposit amount and never learn a larger figure was available.
- Assuming a fixed income means no mortgage. Documented, durable income is exactly what underwriting prefers. Predictability is a feature.
- Forgetting that debts still drive the answer. Debt ratio is usually the binding constraint, and a car payment reduces buying power on fixed income the same way it does on wages.
- Overlooking assets that could be used. Where there is a large retirement balance, there are sometimes options beyond monthly income alone. It depends on the program and it is worth asking.
- Buying without pricing taxes and insurance properly. On a fixed income the payment matters more than usual, those two lines get collected with it, and they move it more than the rate does.
An illustration, so the shape is clear
Numbers below are invented to show the mechanism, not a quote.
Say $3,200 a month arrives from Social Security and none of it is taxable. A client looking at that number reasonably concludes they are a $3,200-a-month buyer and shops accordingly.
The calculation does not use $3,200. It grosses the figure up, because taxable income of the same size would have been reduced by taxes before reaching the household — so the income entering the debt-ratio calculation is meaningfully higher than the deposit.
Add a small pension on top, treated the same way where it is non-taxable, and the qualifying picture moves again.
Nothing about the household's actual money changed, and nothing about the price range worth shopping was ever as small as it looked. What changed is that the calculation stopped understating income it never taxes — and the price range moves with it, sometimes by more than people expect.
What to do now
Ask the question. It is the entire article: is any of my income non-taxable, and is it being grossed up?
Run your scenario — no credit pull, no account, nobody calls you — and bring an award letter and last year's return when you want the exact figure. The gap between what you assume you support and what your file actually supports is often large enough to change which houses you look at.
And if you have been told a fixed income or your age is a problem, get a second look. What a real pre-approval involves is the same process regardless of where the income comes from.
Nothing here is a loan approval, a denial, or a commitment to lend. Program guidelines differ and change, and what applies to a specific file is worth confirming rather than assuming.
Common questions
Can I get a mortgage on Social Security income?
Yes. Social Security is documented, durable income and underwriting generally treats it favorably — an award letter, a 1099 and bank statements showing the deposits are typically what is needed. Because Social Security is often non-taxable, it can frequently be grossed up, meaning the figure used in the calculation is higher than the amount deposited.
What does grossing up income mean?
A mortgage calculation compares gross, pre-tax income against your obligations. Income that is never taxed leaves more spendable money than taxable income of the same size, so guidelines allow non-taxable income to be increased by a set percentage before entering the calculation. The percentage varies by loan program, and the effect is that the income counted can be meaningfully larger than the deposit received.
Is there a maximum age to get a 30-year mortgage?
No. The Equal Credit Opportunity Act prohibits discriminating against a credit applicant on the basis of age, and there is no requirement that a mortgage be repaid within a client's lifetime. Underwriting asks whether the income is likely to continue, not how long the client will. Anyone told otherwise should get a second opinion.
Can I use 401(k) or IRA withdrawals to qualify for a mortgage?
Sometimes, and it has more conditions than Social Security or a pension. It generally requires a documented history of taking distributions and enough remaining balance to support them continuing for a defined period. Because the specifics vary by program and by how the account is structured, it is worth a direct conversation rather than a general assumption in either direction.
Does disability income count for a mortgage?
Generally yes, and it is frequently non-taxable, which means it may be grossed up. The one thing that needs attention is continuance: if an award letter states a defined review or end date, the documentation has to speak to that. Benefits without a stated expiration are typically treated as durable income.
Why would my qualifying income be higher than my monthly deposit?
Because non-taxable income gets grossed up. The calculation works from gross, pre-tax figures, so income that is never taxed would be understated if counted at face value against a taxable earner's gross. The adjustment corrects for that, and it is the single most overlooked lever available to people living on Social Security, disability or a non-taxable pension.
