The Quick Read: When you live in one unit of a duplex, triplex or fourplex, the lender treats the rent from the other units as evidence to document and report. It does not treat that rent as automatic qualifying income. The appraisal supplies a market-rent opinion for each unit. Leases or your tax return then back it up, and the underwriter checks that the documents tell the same story. Your own unit’s rent generally does not count.
Key Takeaways
- Rent from the units you do not live in can help you qualify, but only with the right paperwork and a clean match between documents.
- Rent from the unit you occupy generally cannot be used, with narrow exceptions such as a boarder.
- Even if you qualify without the rent, the lender still records rent for each unit.
- Conventional cash-out on a 2–4 unit home you live in tops out at 75% LTV. LTV, or loan-to-value, is the loan as a share of the home’s appraised value. A one-unit home reaches 80%.
- Streamline refinances for FHA and VA loans do not pay out cash, so they do not need rent documentation.
What Does “Rent Documentation” Mean When You Live in the Building?
It means proving what the other units earn and showing the lender the numbers are real. The proof has three parts: the appraiser’s market-rent opinion for each unit, your lease or tax-return history, and your own rent roll, a unit-by-unit list of tenants, rents and lease dates. A cash-out refinance replaces your current first mortgage with a bigger one and hands you the difference. Lenders look hard at that, because the new payment has to be carried by someone.
The rule that surprises most owners is simple. You live in one unit, so the loan is a principal-residence loan. That keeps the leverage and the pricing category consumer-friendly. It also means your own unit’s rent is not part of your income.
Across the wholesale lenders Lendmire works with, the same pattern shows up on 2–4 unit files. The file goes smoothly when the leases, the appraisal rent schedule and the application agree. It stalls when one of them says something different.
If you want the program side before the paperwork, Lendmire’s cash-out refinance programs page lays out the structures. This article covers the rent side.
Key Terms Defined
Rent schedule: the appraiser’s unit-by-unit opinion of what each unit would rent for in the market.
Rent roll: your own list of units, tenants, rents, lease end dates and status. Lenders often ask for it.
Contract rent: the rent written in the lease.
Market rent: what comparable units in the area rent for, as the appraiser sees it.
Gross rent: the full monthly rent before any vacancy or expense adjustment.
Rent used for lender review: the portion of rent the lender allows to count toward qualifying. It is usually lower than gross rent.
Debt-to-income ratio: your monthly debts, including the new payment, divided by your monthly income.
Seasoning: the minimum age of the loan or ownership before a cash-out is allowed.
How the Loan Is Underwritten, Step by Step
The order matters, because each step feeds the next.
1. Confirm the transaction type. Cash-out pays you money. A rate-and-term refinance only pays off the old loan and costs, with incidental cash back. The two follow different leverage limits.
2. Check occupancy and seasoning. You must live in one unit. The first mortgage being paid off must be at least 12 months old, measured from note date to note date. You must also have been on title for 6 months, with exceptions for delayed financing, inheritance and legal awards.
3. Decide whether rent is needed to qualify. If your own income carries the new payment, the rent is reported but not relied on. If you need the other units’ rent to reach the ratio limit, the full documentation package applies.
4. Collect the rent evidence. That means leases, deposit records, and often the latest signed tax return.
5. Order the appraisal. On a 2–4 unit, the appraiser completes a small-income-property report, which includes the rent comparison for each unit.
6. Reconcile. The underwriter compares the lease rents, the appraiser’s rents, the tax return and your application. Differences get questions.
7. Calculate rent used for lender review. The lender applies its own method, which builds in a cushion for vacancy and expenses, then adds the result to your income picture.
8. Review the Loan Estimate. It shows closing costs and your estimated cash to close, so you can see what the cash-out actually nets.
The program figures, as the wholesale lanes apply them: conventional cash-out reaches 80% LTV on a one-unit principal residence and 75% on a two- to four-unit principal residence. Those caps are subject to lender guidelines and full file review.
How Fannie Mae and the Appraisal Treat Rent
The agency rules behind most conventional files are public. Fannie Mae’s Selling Guide on general rental income says rent from the unit a borrower occupies in a 2–4 unit property generally cannot be used to qualify. Boarder income and accessory-unit income are the named exceptions.
The same guidance requires the lender to report monthly gross rent for each unit on every 2–4 unit principal residence. That applies even when you do not use the rent to qualify. If you think nobody looks at the rent when your salary covers the loan, that is a myth. Someone records it.
The appraisal form matters too. Fannie Mae’s archived rental income text calls for Form 1025, the small residential income property report, on 2–4 units. Form 1007 is the one-unit rent schedule. For a refinance where you already have rental history, the archived text pairs the appraisal’s rent schedule with one of two things:
- the most recent year of signed federal tax returns, including the rental schedule; or current leases, when you can document a qualifying exception such as a major renovation in the prior year.
Fannie Mae also offers a rental income worksheet for principal-residence 2–4 unit properties, Form 1037. Freddie Mac has a parallel worksheet and parallel lease rules, including that the lease be current and fully signed.
Who decides: the appraiser or the lender?
The appraiser gives an opinion of market rent. The lender decides how, and whether, that income counts. People mix those up all the time. A high rent opinion does not raise your qualifying income by itself.
Which Rent Evidence Path Fits Your Situation?
Two paths cover most files. Which one applies depends on your rental history.
| Your situation | Typical evidence | Common snag |
|---|---|---|
| Units rented all prior year | Appraisal rent schedule + signed tax return | Return shows less rent than leases |
| Unit newly rented or acquired | Appraisal + current lease + deposits | Lease too new to show history |
| Unit under renovation last year | Appraisal + lease, as a documented exception | Missing renovation proof |
| Unit vacant now | Appraiser’s market-rent opinion | Lender may not count it |
| Rent not needed to qualify | Rent still reported per unit | Numbers must match the application |
When the lender uses a lease in place of a tax return, it is a named exception, not the default. Expect to explain why.
The Document Checklist, Unit by Unit
Gather this before the file goes in. It shortens the back-and-forth.
| Document | What it proves | Common problem |
|---|---|---|
| Signed lease per rented unit | Contract rent and term | Expired or unsigned |
| Bank deposits for rent | Tenants actually pay | Cash rent with no record |
| Latest signed tax return, with rental schedule | Rent history | Net figure far below lease rent |
| Rent roll | The full picture at a glance | Does not match the leases |
| Appraisal rent schedule | Market rent per unit | Higher or lower than the lease |
| Proof of your housing expense | You carry a residence cost | Missing from the file |
That last line trips people up. Fannie Mae’s Quality Insider notes that using rent from other units generally requires the borrower to own a principal residence or have a documented housing expense, and the file must show it. A principal-residence refinance usually satisfies this on its face, but the paperwork still has to be in the file.
Build Your Rent Roll
A rent roll is not a government form, but a clean one saves questions. Here is the layout, using a fourplex where you live in Unit 1. The entries describe the evidence, not dollar amounts.
| Unit | Occupant | Rent source | Lease status | Evidence |
|---|---|---|---|---|
| 1 | You | Not counted | Owner-occupied | Application |
| 2 | Tenant | Lease | Current, signed | Lease + deposits |
| 3 | Tenant | Lease | Month-to-month | Deposits + statement |
| 4 | Vacant | Appraiser’s opinion | None | Appraisal only |
Every figure on the rent roll should match the lease, the deposit record and the appraisal. If one differs, add a one-line note explaining why.
When the Lease and the Appraisal Disagree
They will sometimes. A tenant may pay less than market because they are a relative, or more because the unit is furnished. Here is how the evidence usually plays out.
| Situation | What the lender sees | Usual fix |
|---|---|---|
| Lease above market rent | Appraiser’s lower number may govern | Expect the lower figure |
| Lease below market rent | Lease rent is the proven amount | Document the lease, accept it |
| Expired lease, tenant staying | Month-to-month | Renew the lease before submitting |
| Newly signed lease | No payment history yet | Add deposit proof |
| Unit under renovation | No current rent | Document the work and the new lease |
| Vacant unit | Market rent only | Do not count on it |
In general, the more conservative number wins. Plan your cash-out around that figure, not the highest one.
Worked Example: A Fourplex, Unit by Unit
Picture a fourplex you live in and have owned for several years. The first mortgage is well past the 12-month mark. You want a cash-out refinance at 75% LTV, the conventional limit for a 2–4 unit principal residence. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
- Unit 1 (yours): the lender ignores its rent. You are the occupant.
- Unit 2: a tenant with a current signed lease and a clean deposit trail. Your latest tax return shows the rent. This is the easy unit.
- Unit 3: a tenant who has gone month-to-month. You sign a fresh lease before applying and add recent deposit records.
- Unit 4: vacant since last spring. The appraiser gives a market-rent opinion. The lender may count little or none of it, depending on its guidelines.
Add it up the way the underwriter does. Units 2 and 3 provide supportable rent. Unit 4 is a question mark. The lender applies its cushion for vacancy and expenses to the supportable rent, then adds the result to your income. If your own earnings already cover the ratio limit, Unit 4 barely matters. If you need every unit, a vacant one is a problem.
Tax Returns and the Schedule E Mismatch
Traditional personal-income documentation can understate what a lease shows. The reason is that the return reports rental income after expenses and depreciation. The lender works from what the return documents, and if the figure is lower than your lease, the underwriter will ask why.
The fix is to line the documents up before the file is submitted. Bring a short written note explaining any gap, such as a unit that was vacant part of the year or a major repair. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Where the General Rule Breaks
The rules above cover the common case. These are the edges.
Your own unit. Its rent generally does not count. Boarder income is a named exception.
Short-term rentals. Nightly or vacation-style rent does not fit the standard monthly rent schedule. Fannie Mae treats short-term-rental income under a separate topic. If one unit is rented by the night, expect that unit’s income to be handled differently or left out.
Accessory dwelling units. Fannie Mae allows accessory-unit rent only on a one-unit principal residence, and only for purchase or limited cash-out loans. So it does not help on a cash-out refinance of a multi-unit home.
An LLC or other entity landlord. When the property is held in an entity, the landlord name on the lease, the deposit account and the title all need to match. Mismatches are a common source of questions.
Utilities included or subsidized units. The lender wants to see what the tenant actually pays. Include the lease terms and any assistance paperwork.
You do not live there. If you do not occupy one of the units, it is an investment property. The conventional cash-out cap on a 2–4 unit is 75% either way, but the rent treatment and the rest of the file change. That is a different loan, not this one.
Streamlines. The FHA Streamline and the VA IRRRL do not pay out cash, so rent documentation does not come up. The FDIC’s summary of the FHA Streamline says it needs no appraisal, requires a net tangible benefit and allows no cash out. The VA’s IRRRL page says the same on cash: none from the proceeds. Net tangible benefit just means the new loan must clearly help you, such as a lower payment or a more stable loan type.
FHA on three and four units. FHA applies an extra rent-based test to three- and four-unit properties that duplexes do not face. The details depend on current FHA guidance, so ask your loan officer to confirm them for your file.
Why Cash-Out on 2–4 Units Has a Lower Cap
Lenders cap leverage lower on multi-unit homes because the property is more complex to value and sell. Fannie Mae’s Eligibility Matrix shows the cash-out limit for a 2–4 unit principal residence below the one-unit limit. In the wholesale programs Lendmire places files with, that means 75% on 2–4 units against 80% on a single unit.
In practice, a 75% cap on a multi-unit home leaves you with less cash than the same equity would on a house. Your cash-out also depends on the appraised value, the payoff and the closing costs. The Loan Estimate shows what you would net.
Common Reasons Files Stall
- Documents disagree. Leases, deposits, tax return and application each say something different.
- Expired leases. A lease that ended last year is not a current lease.
- Cash rent. Rent paid in cash with no deposit trail is hard to prove.
- Missing housing-expense proof. The file needs to show your own residence cost.
- Vacant units counted as income. The lender may not give credit for rent no one is paying.
- Seasoning missed. A recent purchase or refinance can put you under the 12-month mark.
A pre-submission self-audit is worth doing. Check each unit against each document, and fix gaps before the appraiser walks through.
What the Decision Looks Like in Practice
Most owners face one real choice. Is the cash worth a bigger loan on a building you also live in? A cash-out raises your balance and your payment. A cheaper option may be keeping your current loan and borrowing less. Look at the documentation first, because it tells you how much of the rent the lender will credit.
If the lender counts the other units’ rent, your debt-to-income ratio improves. If it does not, your own income has to carry the new payment. Run the plan both ways before you commit.
Frequently Asked Questions
Do I need leases for every unit?
Generally yes, for each rented unit. If a unit is vacant, the appraiser’s market-rent opinion stands in, though the lender may count little of it. Month-to-month tenants should sign a fresh lease before you apply.
Is my own unit’s rent ever counted?
Rarely. Rent from the unit you occupy generally cannot be used to qualify. Boarder income is a named exception, and accessory-unit income only applies in narrow cases that do not extend to a cash-out on a multi-unit home.
Does the lender report rent if I do not need it to qualify?
Yes. Rent is recorded for each unit on 2–4 unit principal residences whether or not you use it. The figure can come from the appraisal, or from your written statement or application if no appraisal is needed.
What if my tax return shows less rent than my leases?
Expect questions. Returns report income after expenses, so they can come in below lease rent. A short written explanation, such as a vacancy or a repair year, plus matching deposit records usually helps.
Can I use an FHA Streamline or VA IRRRL to take cash out of a duplex?
No. Neither allows cash out. If you want cash, you would look at a cash-out refinance instead, which brings the rent documentation here into play.
