The Quick Read: Usually not, if you live in a one-unit home and the loan is conventional. Lenders generally treat rent from a roommate or boarder as income they can’t use. With a low first mortgage, you often don’t need it, because your paycheck may carry the new loan alone.
- Conventional one-unit homes: boarder rent generally does not count, apart from a narrow live-in aide exception.
- FHA is the main exception, but the details matter, and cash-out use needs a lender check.
- Two- to four-unit homes you live in can count rent from the units you don’t occupy.
- A cash-out resets the payment on the whole balance, so the new loan has to qualify on its own.
- Leverage caps limit your cash no matter how much income you show.
Which Lane Are You In?
Your lane depends on how many units the home has and which program the loan belongs to. Occupancy decides the rules first. Rent only helps if the program’s guidelines accept that kind of rent.
Cash-out refinance estimate
The starting figures are an example value with a balance and a cash request in proportion. Replace them with yours.
Editable benchmark: 7.40% as of October 15, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a cash-out refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $193,000 current balance, the agency cap on a one-unit principal residence, a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a cash-out refinance quote; a cash-out loan is priced by the lender at lock. The cash available is the loan the program cap allows less the balances paid off, before closing costs, which are not included. The HELOC line is the program’s combined loan-to-value ceiling applied to the same value and balance. Taxes and insurance are editable estimates. Licensed in sixteen states for consumer mortgages.
A boarder is someone who rents space inside the home you live in. An accessory unit (a separate garage apartment, say) is a different thing. HUD’s FHA letter on boarder income says outright that a renter of an accessory unit is not a boarder, per HUD Mortgagee Letter 2025-04.
| Your situation | Does the rent count? | What the lender uses |
|---|---|---|
| One-unit home, conventional, roommate in a bedroom | Generally no | Your job and other eligible income |
| One-unit home, FHA, roommate with a history | Possibly, if documented | Income plus documented boarder rent |
| Two- to four-unit home you live in | Rent from units you don’t occupy can count | Your income plus eligible rent |
| Live-in aide for a borrower with a disability | Yes, in a narrow case | Rent from the aide, capped |
Subject to lender guidelines and full file review, that table is the map.
What Do the Conventional Rules Say?
Conventional guidelines are the strictest on this. Fannie Mae’s Selling Guide section on boarder income says rent from boarders living in your principal residence or second home is not acceptable stable income. The one exception is a borrower with a disability who receives rent from a live-in personal assistant. That income is capped as a share of qualifying income.
Freddie Mac is similar. Freddie Mac Guide section 5306.1 allows rent on a one-unit primary residence only from a live-in aide or an accessory dwelling unit. Ordinary room rent isn’t on that list. It also says rental income from a second home may not be used as stable monthly income.
Some low-down-payment programs do allow boarder income in certain cases, HomeReady being the best known. Those programs are built for purchases and limited cash-out refinances, not true cash-out. Across the wholesale programs Lendmire places files with, a roommate’s rent doesn’t rescue a conventional cash-out. Plan on your own income carrying the loan.
Why Does the Answer Change on a Cash-Out?
A cash-out refinance is a new loan that pays off your first mortgage and hands you the extra equity as cash. A limited cash-out (also called rate-and-term) refinance pays off the old loan and closing costs and allows only incidental cash back. Fannie Mae’s announcement on limited cash-out and accessory unit income sets a small cap on cash back for the limited version. Anything beyond it is a cash-out.
Why does that matter for rent? Rental-income rules are written by transaction type. A rule that works on a purchase or a limited refinance may not carry over to a cash-out. That’s the trap with accessory unit rent: Fannie Mae allows it only on a one-unit principal residence, and only for purchases and limited cash-out refinances. A true cash-out is outside that rule.
Seasoning is the waiting period a lender wants before you can refinance. On a conventional cash-out, the first mortgage being paid off generally needs to be at least 12 months old, measured note date to note date, and you generally need to have been on title for 6 months. Delayed financing, inheritance and legal-award exceptions exist. Subject to lender guidelines.
If you are weighing a conventional route, Lendmire’s cash-out refinance programs page lays out how the options differ.
What Does a Low First Mortgage Do to the Math?
It makes the rent question smaller. A cash-out replaces your entire first mortgage with one new loan. The old low balance disappears into a bigger balance, and the payment gets reset on all of it. Call that blended repricing: the cheap part of your old loan gets averaged into the new one.
Here is the basic picture, in percentages only. Say your first mortgage is about 30% of your home’s value. On a one-unit principal residence, a conventional cash-out generally tops out at 80% loan-to-value (LTV, the loan as a share of the appraised value), per Fannie Mae’s eligibility matrix. You could take the new loan up to that ceiling. Take out less, and the new loan stays smaller.
That’s the useful part. Underwriters weigh the new payment against your income, a measure called debt-to-income. A modest new loan can fit on wages alone. When it does, rent that can’t be counted doesn’t matter. When you stretch toward the ceiling, the payment grows and the income gets tight. That is when borrowers start hunting for rent to count, and that is when it usually can’t.
The wholesale programs also have a conventional lane that reaches 89.99% LTV with no mortgage insurance. It requires a 680 score and a 50% ratio on a thirty-year fixed, primary residence, conforming balance, with its own six months of seasoning. It still is reviewed around income the guidelines accept. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
One more point on cash. LTV caps limit what you can take regardless of income. The appraisal sets the value. Rent doesn’t raise it, and it doesn’t raise your cash.
How Does FHA Treat Boarder Rent?
FHA is where the rules loosened. A 2025 HUD mortgagee letter let lenders count boarder rent as effective income. The borrower needs a history of receiving it and must be receiving it now. HUD later folded the letter into its Handbook 4000.1 in Handbook Update 17.
Here is the catch. It isn’t clear that the boarder rule reaches FHA cash-out refinances specifically, so don’t assume it does. Ask your loan officer to check the current Handbook language before you build a plan on it.
If you already have an FHA or VA loan, the streamlines are a separate story. The FHA Streamline (no appraisal, limited credit review, net tangible benefit) and the VA IRRRL (no VA appraisal, net tangible benefit, a 0.5% funding fee unless exempt, seasoning of the later of 210 days and 6 payments) are not cash-out loans. Room rent is irrelevant to them. If a VA borrower wants cash, the VA cash-out refinance is the path, and it needs full verification. VA.gov is the place for the details.
What About Two- to Four-Unit Homes?
Here rent can count. Fannie Mae’s guide generally doesn’t let you use income from a one-unit principal residence, or from the unit you occupy in a two- to four-unit home. But rent from the units you rent to others is a different matter. Freddie Mac’s guide lists rent from units the borrower doesn’t occupy as eligible, and it counts only a reduced share of the lease or market rent.
The tradeoff is leverage. A conventional cash-out on a two- to four-unit principal residence generally tops out at 75% LTV, against 80% on a one-unit home. So counting rent costs you some cash.
One sentence on occupancy, since people ask: if the home isn’t your primary residence, the same 75% cap applies on a conventional cash-out for second homes and investment property, and occupancy decides the leverage.
What Proof Do Lenders Want When Rent Does Count?
Lenders verify income they rely on. They don’t verify income they ignore. That is why a lender that won’t count your roommate’s rent also won’t ask you to prove it.
When it does count, expect to document:
- A history of receipt. In Fannie’s own HomeReady example, rent documented for the prior 12 months is divided by 12 to get the monthly figure.
- Proof of payment. Bank statements, canceled checks or traditional personal-income documentation. Cash that never touches an account is hard to prove.
- Proof the person lives with you. A shared address on records.
- A written agreement. Terms spelled out, not a handshake.
- Consistency. The lease, the deposits and your tax return should tell the same story. Mismatches sink files.
Federal ability-to-repay rules require a lender to consider your current or reasonably expected income or assets and verify what it uses. The rule doesn’t ban rent as income. The investor guidelines decide what’s eligible. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Common Mistakes
Counting a roommate’s rent in full. Assuming a high home value means big cash. Treating HomeReady boarder rules as a green light for any cash-out. Taking cash rent off the books and then trying to use it later. Believing every FHA refinance can use boarder income. And mixing up a boarder with an accessory unit tenant (they are different, and the rules for each differ too).
If the Rent Doesn’t Count: Your Options
When income falls short, you adjust the loan, not the rent. Here is how the choices compare.
| Option | What it does | Tradeoff |
|---|---|---|
| Smaller cash-out | Keeps the new loan modest | Less cash |
| Second lien or HELOC | Leaves your low first mortgage alone | Separate payment and terms |
| Wait and document | Builds a history for programs that count rent | You wait |
| Add a co-borrower | Brings a second income and debts | Shared liability |
| A different program | FHA or a limited cash-out may fit | Different limits |
It’s a close call for many homeowners: giving up a cheap loan to fund a one-time need is rarely free.

Frequently Asked Questions
Can I count what each roommate pays me?
Not on a conventional one-unit cash-out, generally. The exception is a live-in aide for a borrower with a disability. FHA may count boarder rent with a documented history and a written agreement, but confirm how it applies to cash-out. Everything is subject to lender guidelines.
Does a roommate have to go on the loan?
No. A roommate who only pays rent stays off the loan and the title. Adding one as a co-borrower is a different structure: their income and debts both enter the file, and they share the obligation.
Do cash payments count?
Rarely. A lender can only use income it can verify, and cash that never reaches a bank account leaves no clean record. Deposits, canceled checks and traditional personal-income documentation are what lenders look for.
What if my current mortgage is low?
Then a smaller cash-out may serve you better. A cash-out replaces the whole balance, so you give up the low loan to get the cash. Weigh a second lien or a smaller draw against that.
How much can I pull out?
It depends on the appraised value and the program. A conventional cash-out on a one-unit principal residence generally tops out at 80% LTV, and 75% on two- to four-unit homes. Your income must also support the new loan.
