They first verify that the income is documented and likely to continue, then apply the rules for your loan program and property. The calculation may reduce gross rent for vacancy and expenses, subtract the property’s full principal, interest, taxes, insurance and association dues (PITIA), add a positive net amount to qualifying income, or treat a negative amount as a monthly debt.
The result depends most on where the rent comes from: the home you are buying, an existing investment property, a home you are leaving, an accessory dwelling unit (ADU), or a boarder renting space in your home. The same lease can produce different qualifying results under conventional, FHA, VA and portfolio underwriting.

Can I use rental income to qualify for a mortgage?
Usually, yes—if the lender can establish that the rent is stable, documented and likely to continue under the applicable underwriting guide. Fannie Mae’s Selling Guide states: “Rental Income is an acceptable source of stable income if it can be established that the income is likely to continue.”
That does not mean a lender adds your advertised rent or the full lease amount to salary. Underwriting evaluates the property’s housing expense, the evidence supporting the rent, your rental-management history and whether the loan program permits positive rental income in your circumstances. Fannie Mae also says that the amount used may be restricted by whether you currently have a housing payment and whether you have property-management experience.
#1 Best Overall
Before relying on rent, identify the loan program and the property category. A conventional loan secured by a one-unit home you are purchasing is calculated differently from an existing rental, a departing residence or an FHA boarder arrangement.
How much rental income do mortgage lenders count?
The familiar “75% of rent” rule is a calculation step in some programs, not a universal lending rule. The table shows the principal treatments documented in current official guidance. Your lender may impose additional requirements.
| Situation | Calculation or limit | How the result affects qualifying |
|---|---|---|
| Fannie Mae subject property purchase | Supported monthly gross rent × 75%, then subtract the property’s full PITIA. | The result is adjusted net rental income (ANRI). Positive ANRI may increase qualifying income when the borrower has at least 12 months of rental-property management experience. With less experience, positive ANRI can generally offset PITIA only; a negative ANRI enters the debt-to-income calculation. |
| Fannie Mae existing rental property | Qualifying rent minus full PITIA, calculated for each property. | A positive net amount is added to total income. A negative net amount is treated as a monthly rental loss. The rental PITIA is not counted a second time, although the borrower’s current principal-residence payment remains a monthly obligation. |
| FHA subject property with limited or no rental history | HUD Handbook 4000.1 uses 75% of the lesser of appraiser-reported fair-market rent or lease rent. | The total mortgage payment is not simply reduced by the net subject-property rent. FHA’s exact treatment depends on the applicable history and documentation provisions. |
| VA existing property | The VA underwriting excerpt states that 75% of the lease or rental-agreement amount is included unless a greater percentage can be documented. | Verify the current VA rule and lender overlays; the available excerpt is narrower than a complete program review. |
| Fannie Mae existing ADU | For eligible purchase or limited cash-out refinance cases, rental income from one existing ADU is limited to 30% of total qualifying income. | The cap applies to the qualifying-income calculation and does not make every ADU rent automatically acceptable. |
| FHA boarder income | HUD’s policy summary caps qualifying boarder income at 30% of total monthly effective income. | The policy requires a 12-month rental history, receipt in at least nine of the most recent 12 months and current receipt, for FHA case numbers assigned on or after March 14, 2025. |
Fannie Mae’s general and subject-property rental-income sections were dated September 2, 2026. HUD’s housing-handbook index lists an August 12, 2026, Handbook 4000.1 update; an earlier rental-income excerpt should therefore be confirmed against the current handbook and your lender’s procedures.
Can I use rent from the house I’m buying to qualify?
For an eligible one- to four-unit Fannie Mae subject-property purchase, the basic calculation is:
Rank #2
- Ideal for Gifting
- Ideal for a bookworm
- Compact for travelling
- Establish supported monthly gross rent, using the documentation permitted for the property and transaction.
- Multiply that rent by 75%.
- Subtract the subject property’s full monthly PITIA, including applicable association dues.
- Classify the result as positive or negative ANRI and apply the borrower-experience rules.
For example, documented rent of $2,000 per month produces $1,500 after the 75% calculation. If monthly PITIA is $1,300, ANRI is $200. That arithmetic is not an approval or borrowing estimate: the $200 can increase qualifying income only when the borrower meets the experience and eligibility requirements. With less than 12 months of rental-property management experience, the positive amount generally offsets the property’s PITIA rather than increasing income above it. If the calculation is negative, the loss affects debt-to-income.
For a refinance, Fannie Mae may use Schedule E cash flow averaged over the relevant period and subtract PITIA. If the property is not on the most recent tax return, a 75%-of-lease calculation may be available when the guide permits that method. Ask which calculation the underwriter will use before assuming that a current lease will replace tax-return history.
Will my rental property help me borrow more?
An existing rental can improve borrowing capacity when its qualifying income exceeds its full PITIA and the program allows the positive net amount to be added to income. If rent is lower than PITIA, the shortfall reduces capacity because it is treated as a monthly obligation.
Experience and housing-payment restrictions
Under Fannie Mae’s current guidance, at least 12 months of rental-property management experience permits eligible positive rental income to be used in qualifying. With no or less than 12 months of experience, positive rental income can generally offset the property’s PITIA only. Fannie Mae also restricts positive rental income to PITIA offset in situations where the borrower has no current housing payment or has not documented one, subject to the complete guide requirements.
Multiple rental properties
Each rental property is calculated separately. The lender then aggregates the positive and negative results. A profitable property does not automatically erase an unrelated property’s loss; both must be documented and included under the applicable guide.
Do not double-count the rental mortgage
For Fannie Mae existing rentals, the full rental-property PITIA is already included in the net-rent calculation. It is not added again as a separate debt. Your current principal-residence payment, however, remains part of the monthly obligations used for underwriting.
Can I count rent if I just signed a lease?
A newly signed lease may be usable, but a signature alone is not always sufficient. The lender may need proof that the lease is fully executed, has taken effect and is producing—or is about to produce—the stated rent.

Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Under Fannie Mae’s general guide, a newly executed lease dated within two months of application for a property not reported on the borrower’s individual tax return generally must run for at least six months, with the first rent due by the first payment on the subject mortgage. The lender must validate lease terms for certain properties absent from the most recent tax return.
Rank #4
Possible validation includes recent bank statements showing rent deposits, payment records, proof of the security deposit and an appraisal-supported market-rent schedule. If the lease rent differs materially from supported market rent, expect questions and additional documentation.
Does rental income count if I’m moving out of my current home?
Rent from a home you are leaving is commonly evaluated as income from a non-principal-residence property, but the lender must establish the property’s new rental use and account for both housing obligations. The departing home’s PITIA, the new home’s payment and any documented rent all affect the debt-to-income calculation under the selected program.
Provide a signed lease, evidence of rent receipt when available, the property’s payment information and an explanation for any vacancy, renovation or repair period. If the home has not appeared on your tax return, the lender may use a permitted lease-and-market-rent method rather than assuming the entire lease amount is dependable income.

The exact package varies by property and transaction. A lender may request:
Best Value
- It can be a gift option
- Comes with secure packaging
- Helpful in various ways
- Signed federal tax returns with Schedules 1 and E, or applicable business returns including Form 8825, to establish rental history and management experience.
- A fully executed lease and evidence that its terms have taken effect, such as recent rent deposits or payment records.
- An appraisal rent schedule—Fannie Mae identifies Form 1007 for a one-unit property or Form 1025 for a small residential income property, as applicable.
- Evidence of your current housing payment when rent from the subject property is being used.
- Records explaining rental interruptions, renovation or repair periods, vacancies, or differences between lease rent and supported market rent.
- Property tax, insurance, association-dues and mortgage information needed to establish complete PITIA.
Organize documents by property and month. Missing deposits, unexplained gaps or an incomplete lease can delay underwriting even when the headline rent appears sufficient.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to calculate your scenario before applying
- Name the program. Ask whether the application will be under a conventional agency guide, FHA, VA or a portfolio/jumbo policy.
- Classify the property. Identify it as the subject purchase, an existing rental, a departing residence, an ADU or a boarder arrangement.
- List the evidence. Note tax-return history, lease dates, market-rent support, deposits and months of management experience.
- Calculate complete PITIA. Include principal, interest, taxes, insurance and applicable association dues; do not use principal and interest alone.
- Apply the permitted rent method. Confirm whether the lender uses 75% of rent, Schedule E cash flow, an appraiser-supported amount, or another program-specific formula.
- Classify the net result. Determine whether positive rent increases income, only offsets PITIA, or becomes a loss obligation.
- Recalculate debt-to-income. Include the current residence, the new mortgage and any other rental losses or obligations that the guide requires.
Why FHA, VA and Freddie Mac estimates should not be blended
FHA, VA and conventional underwriting may use similar percentages while applying them to different bases and requiring different history. HUD’s FHA result for limited-history subject-property income uses 75% of the lesser of fair-market rent or lease rent, and HUD separately describes boarder-income conditions. The VA underwriting excerpt refers to 75% of lease or rental-agreement income unless a greater percentage is documented. Those statements are not interchangeable with Fannie Mae’s subject-property ANRI formula.
Freddie Mac’s guidance includes a net-rental-income calculation and lease exceptions, but no detailed guide language is available for a reliable comparison. Do not use Fannie Mae’s formula as a substitute for Freddie Mac’s current guide. Ask the lender to identify the exact section governing your file.

Questions to ask your lender
- Which loan program and underwriting guide govern my application?
- Is this income from the property I’m buying, an existing investment property, a departing residence, an ADU or a boarder?
- Will you use Schedule E history, a current executed lease, an appraisal-supported market rent, or more than one source?
- What percentage or expense calculation applies, and which PITIA components will be subtracted?
- Do I have enough documented rental history or management experience for positive net rent to increase qualifying income?
- How will a rental loss, vacancy period or another mortgage payment affect my debt-to-income ratio?
- What lender-specific requirements apply beyond the agency or government-program guidance?
What rental income can—and cannot—do for approval
Rental income can increase qualifying income when the documented net amount is positive and your program permits it. It can also merely offset a property’s housing cost, or reduce borrowing capacity when the property operates at a documented loss. There is no universal amount of extra borrowing created by a given rent figure: the outcome depends on the program, PITIA, documentation, management history, other debts and lender overlays.
