The Quick Read: On a standard conventional cash-out refinance, rent from roomers in the home you live in usually counts as zero qualifying income. A few exceptions let some of it count, and each comes with a cap and a paper trail. No single percentage applies to every house, so the better question is which program you are in and how the lender classifies the property. Terms vary by program and are subject to lender guidelines and full file review.
Key Takeaways
- A one-unit house with rented bedrooms is still a one-unit house. Conventional underwriting treats that rent as boarder income, which generally does not qualify.
- Rent can count in three narrow cases: an affordable-lending feature, a true two- to four-unit home where you rent the units you don’t live in, and a live-in personal assistant exception.
- Where rent does count, it is capped and needs a documented history, usually bank-statement proof.
- Cash-out leverage depends on units and occupancy. A one-unit primary residence reaches 80% LTV. Two- to four-unit homes reach 75%.
- FHA and VA streamlines mostly skip the income question, but they do not pay out meaningful cash.
- Plan the loan so it works without the room rent. Treat any counted rent as a bonus.
Why Room Rent Is Treated Differently From Other Rent
A lender sizing a cash-out refinance asks one thing about income: will it keep arriving? A roommate can move out next month. A tenant in a separate unit sits under a lease and a landlord-tenant relationship. A roomer shares your kitchen and your front door.
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.
Underwriting guidelines split these into two groups. Rent from a separate rental unit is rental income. Rent from someone living in your own space is boarder income.
That split drives nearly everything below. It also explains why a house that looks like a strong earner on paper can look thin to a lender. Four room leases add up to a nice monthly number, but the lender may recognize none of it.
Which Rule Governs Your House?
The first question is how many units the house has. How many rooms you rent comes second. Here is how the paths usually sort out.
| Your setup | How room rent is usually read | Typical result |
|---|---|---|
| One-unit home, you live there, rent bedrooms | Boarder income | Generally $0 counted |
| Same, inside an affordable-lending feature | Boarder income, capped | May count in part |
| True 2–4 unit home, you live in one unit | Rent from units you don’t occupy | Can count |
| One-unit home with a live-in personal assistant (disabled borrower) | Narrow exception | Can count, capped |
| You don’t live there at all | Occupancy changes the loan type | Different leverage rules |
On that last row, occupancy decides leverage. A conventional cash-out on a one-unit principal residence reaches 80% LTV. On a second home or investment property it is 75%. Lendmire’s refinance work stays in the owner-occupied lane, so the rest of this piece assumes you live in the house. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
What the Agency Rules Say
The conventional rulebook is public, and you can read it yourself. The Fannie Mae Selling Guide’s rental income rule says rent from a borrower’s principal residence generally cannot be used to qualify. That covers a one-unit home and the unit you occupy in a two- to four-unit property. The guide then lists exceptions for boarder income and for principal residences with accessory units.
The boarder income section is blunter. Boarder rent from a principal residence is not acceptable stable income. The exceptions are a borrower with disabilities who receives rent from a live-in personal assistant, and the affordable-lending feature covered below. The assistant exception applies whether or not that person is a relative. It counts up to 30% of the total gross income used to qualify.
Both exceptions come with paperwork. You need a history of shared residency and a 12-month history of receipt. The payments must show full, regular and timely receipt. Cash handed over and never deposited is a problem.
The HomeReady Exception and Its Cap
HomeReady is Fannie Mae’s affordable-lending feature. Freddie Mac has a sibling called Home Possible. Both carry an income limit of 80% of area median income for the property’s location. Both are aimed at borrowers with moderate incomes.
Fannie Mae’s job aid on HomeReady boarder income says boarder rent can count there, up to 30% of qualifying income. Read that cap carefully. It is a share of total qualifying income, not a share of the rent. If your job income is modest and your room rent is large, the cap trims it.
Two cautions from practice:
- Freddie Mac’s version of this feature has its own boarder wording and its own receipt period. Don’t assume the two programs match.
- Whether a given feature is available on a full cash-out file, as opposed to a limited cash-out, depends on the program matrix and the lender’s own rules. Confirm it before you count on it.
Boarder Income Versus an Accessory Unit
A rented bedroom and an accessory dwelling unit (ADU) are not the same thing. An ADU is a separate living space on the property, such as a garage apartment or basement unit with its own entrance and kitchen. Its rent follows a different treatment.
In Fannie Mae’s worked example, ADU rent is reduced for vacancy and loss. The rent used to qualify is also capped at a share of qualifying income. Freddie Mac’s rule for a one-unit primary residence accepts only two kinds of rent: from a live-in aide or from an ADU. Its guide section on rental income also expects stable rent to continue for at least three years.
That three-year idea matters for roommates. Roommates leave. A lender asking whether the rent will last is why a room rented by the month rarely earns credit.
Step by Step: How the Loan Is Underwritten
Here is the sequence on a typical conventional cash-out file, with the room-rent decision at each stage.
1. Classify the property. The lender counts legal units, not rented rooms. A one-unit house with several roomers stays a one-unit house. Local zoning and licensing rules can complicate a house with many unrelated occupants, so the way it is used must match what the file says.
2. Pick the program. Standard conventional treats room rent as $0. An affordable-lending feature may allow a capped amount.
3. Check the prerequisites. For the affordable features, household income must sit at or below the area limit.
4. Document shared residency. Driver’s licenses, bills, bank statements or W-2s should show the roomer’s address matches yours.
5. Document the payments. The lender wants 12 months of receipt through bank statements, cancelled checks or other electronic records.
6. Calculate. Eligible rent is added to income and capped. It is not subtracted from your housing payment.
7. For a true two- to four-unit home, use the rent worksheet. Fannie Mae’s rental income worksheet (Form 1037) reports the monthly gross rent on the units you don’t occupy. Support comes from the appraisal or a rent schedule dated within the prior 12 months. If a unit is vacant, the appraiser’s opinion of market rent can be used.
8. Appraisal. The appraiser sets the value, and the value sets the maximum cash-out. Room rent does not raise the value of a one-unit home. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
9. Automated underwriting. The file runs through the agency’s system, which issues findings.
10. Final review. If the income doesn’t qualify, the file is re-run without the rent. This is a common reason expected cash-out shrinks.
How the Cash-Out Amount Is Set
Cash-out is a leverage rule first. A conventional cash-out refinance on a one-unit principal residence reaches 80% LTV. LTV, or loan-to-value, is the loan balance divided by the home’s appraised value. A two- to four-unit principal residence reaches 75%. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
The new loan pays off your existing mortgage and the closing costs. What is left is yours. The leverage cap, not the room rent, sets the ceiling.
There is also a seasoning test. Seasoning is the waiting period a lender wants before a refinance. The first mortgage being paid off must be at least 12 months old, and you must have been on title for 6 months. Delayed financing, inheritance and legal-award exceptions exist.
In some wholesale lanes, a primary residence with a conforming balance can reach 89.99% LTV with no mortgage insurance. It takes a 680 score, a 50% ratio and its own six months of seasoning on a thirty-year fixed. It is not written on Texas homesteads, where the state constitution caps cash-out at the agency figure. These lanes still ask whether you qualify on your own income, so the room rent question doesn’t go away. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
A Worked Illustration
Picture a one-unit house you live in. You rent four bedrooms to four people, and the leases add up to a healthy-looking monthly total. Everything below uses modeled assumptions, not market data.
| Scenario | Rent the lender counts | What it means |
|---|---|---|
| Four room leases added up | $0 on a standard conventional file | Looks strong, counts as nothing |
| Same house, affordable feature, modest draw | Part of it, capped at a share of income | Rent helps only if documented |
| Same rent, maximum draw to the leverage cap | Same capped amount | More cash taken, tighter file |
The takeaway is that the rent figure stays fixed while the draw changes. A bigger draw means a bigger loan against the same income. In the third row, the file leans harder on income the lender only partly recognizes.
When the General Rule Breaks
Real files produce odd cases. These come up most:
- Legal use. A house rented to many unrelated people may not fit neatly as a one-unit home or as a two- to four-unit property. How it is classified is a lender and appraisal question, and zoning and licensing questions sit outside this article.
- First-time landlord on a two- to four-unit. Rent without a one-year history can be capped at your housing payment.
- Non-occupant co-borrower. FHA does not allow a non-occupant co-borrower’s income on a cash-out refinance.
- Related roomers. The live-in assistant exception applies whether or not the person is a relative. Ordinary roomers who are relatives still don’t qualify as stable income.
- Cash-out versus limited cash-out. A limited cash-out (the rate-and-term lane) reaches 95% LTV on a one-unit principal residence. Income is read the same way, but the leverage ceiling is higher. That is the reason some borrowers choose to skip the cash.
What About FHA and VA?
FHA cash-out is full underwriting, and HUD says the streamline is a different product. A streamline requires an existing FHA loan that is current. It also requires a net tangible benefit and does not allow meaningful cash back.
The VA’s streamline for existing VA loans works the same way in spirit. There is no VA appraisal and no income analysis. The loan needs a net tangible benefit and seasoning. So room rent is a non-issue there, but so is cash-out. A VA cash-out refinance is full underwriting.
A Document Checklist for Room-by-Room Households
If you plan to rely on any room rent, gather this before you apply:
- A written agreement for each roomer with names, dates and amounts.
- Bank statements showing each payment landing, month after month.
- Proof the roomer lives at your address, such as a license or a bill.
- Your own tax filings, so the figures match.
- A plain explanation of the setup (who lives where, what each person pays).
Mismatched paperwork is the usual problem. A roomer’s license showing another address, or payments that never hit a bank account, can unwind a file late.
Common Mistakes
- Counting vacant rooms or rent you expect to collect.
- Assuming an FHA or VA streamline will count rent or pay out cash.
- Treating a rented bedroom and an ADU as the same thing.
- Sizing the cash-out on rent the lender may drop at final review.
- Counting rent that is not documented as received.
If the Rent Isn’t Counted
Plan for it. These options help:
- Take a smaller draw. A lower balance means the file leans less on income the lender won’t count.
- Compare programs. The affordable features, the limited cash-out lane and the standard cash-out lane read the same house differently.
- Document earlier. If a program allows capped boarder rent, start the 12-month receipt trail now.
- Keep the loan you have. Sometimes the honest answer is not to refinance at all.

Frequently Asked Questions
Does my roommates’ rent count toward a cash-out refinance?
Usually not, on a standard conventional loan. Rent from people living in your own principal residence generally cannot be used to qualify. Exceptions exist for an affordable-lending feature and for a live-in personal assistant, each with a cap and documentation. Eligibility is subject to lender guidelines.
Is there a percentage of room rent that always counts?
No. The only cap that applies is a share of your total qualifying income, not a share of the rent. A better question is whether your program counts any boarder rent at all.
Does the answer change if I live in the house or don’t?
Yes. Occupancy decides leverage. Occupancy also changes which loan type applies.
Can projected or future room rent count?
Generally not. Rent that counts must show a documented history of full, regular receipt, and the lender weighs whether it is likely to continue. Rent you expect to collect is a plan, not income.
Do FHA and VA streamlines count my room rent?
They are built to need little or no income analysis, so rent is mostly irrelevant. They also don’t pay out meaningful cash. If you want cash from your equity, you need a cash-out refinance with full underwriting.
