New Fannie Mae Rule Makes It Easier to Turn Your Current Home Into a Rental
Buying another home while keeping your current property as a rental may be getting easier.
Fannie Mae recently changed how lenders can document rental income when a homeowner purchases a new primary residence and converts the home they are leaving into an investment property.
Previously, buyers commonly needed to find a tenant and execute a lease before the expected rental income could be considered during mortgage qualification.
Under the new guideline, lease agreements are no longer permitted to determine rental income from a departing primary residence.
Instead, the lender can use supported market-rent data.
This means an eligible buyer may be able to use potential rental income from the current home without securing a tenant or signing a lease before closing on the next property.

What Is a Departing Primary Residence?
A departing primary residence is the home in which you currently live but plan to vacate when you purchase another primary residence.
Instead of selling the current home, you convert it into an investment property and rent it to a tenant.
For example, you might currently own a townhome in Charlotte but need a larger home because your family is growing.
You decide to purchase a new home in Matthews, Waxhaw, Fort Mill, Indian Land, or another Charlotte-area community. Instead of selling the townhome, you would like to keep it and turn it into a long-term rental.
The existing payment on that property would normally be included in your debt-to-income ratio when qualifying for the next mortgage.
If eligible rental income can offset some or all of that payment, keeping the property may become much more realistic.
What Did Fannie Mae Change?
Under previous guidelines, a signed lease agreement was commonly used to document the expected rental income from a departing residence.
That created a practical challenge.
A homeowner might need to:
Find a qualified tenant
Agree on the rent
Sign a lease
Establish a move-in date
Vacate the current home
Purchase and close on the next home
Coordinating those events can be difficult, especially when the purchase of the next home is not guaranteed to close on a specific date.
Fannie Mae’s new rule replaces the lease-based approach with a market-rent approach.
The lender can now determine the departing home’s expected monthly rent using:
A complete appraisal report that includes market rent
A Single-Family Comparable Rent Schedule, also known as Form 1007
A market-rent analysis using sources such as the MLS, Zillow, or Redfin
When a market-rent analysis tool is used, the lender must obtain at least three comparable rental properties.
The comparable rentals should be located in the same market area and, whenever possible, within the same subdivision or condominium project.
Fannie Mae’s current guideline specifically states that lease agreements are not permitted for a departing residence.
You can review the official requirement in Fannie Mae’s departing-residence rental-income guidelines.
Why Could This Make the Process Easier?
The biggest benefit is timing.
A buyer may no longer need to find a tenant and sign a lease before the rental income can be considered.
That can reduce the pressure to coordinate a tenant’s move-in date with the closing date for the next home.
Under the previous process, homeowners could face several problems:
The tenant might need to move in before the homeowner can leave.
The purchase closing could be delayed after the lease has already begun.
The homeowner might feel pressured to accept the first available tenant.
The agreed rent might not be supported by the surrounding rental market.
The buyer could be temporarily left without a residence if the transactions did not align.
Using supported market rent allows the lender to evaluate the property’s rental potential independently of a signed lease.
This does not guarantee mortgage approval, but it can remove one of the logistical obstacles involved in converting a current home into a rental.
Does This Mean You Never Need a Lease?
No.
A written lease may still be necessary when you actually rent the property to a tenant. State law, local requirements, insurance considerations, and good property-management practices still apply.
The Fannie Mae change concerns how the lender documents rental income for mortgage qualification.
It does not suggest that homeowners should operate a rental property indefinitely without a written agreement.
The important distinction is that an eligible borrower may not need a signed lease in place before closing on the new mortgage.
How Does the 75% Rental-Income Calculation Work?
Fannie Mae does not allow the lender to use 100% of the supported market rent.
The lender generally multiplies the monthly market rent by 75%.
The remaining 25% accounts for potential vacancy and ongoing property expenses.
The basic calculation is:
Supported monthly market rent × 75%
The lender then compares the result against the departing home’s complete monthly housing expense.
What Expenses Must the Rent Cover?
The lender does not compare 75% of the rent against only the principal-and-interest portion of the mortgage payment.
The calculation uses the complete PITIA obligation for the departing residence.
Depending on the property, that may include:
Mortgage principal
Mortgage interest
Property taxes
Homeowners insurance
Flood insurance, when applicable
Mortgage insurance
HOA or condominium association dues
Applicable assessments
Other required components of the monthly housing expense
This distinction is important because a property’s principal-and-interest payment may be substantially lower than its complete monthly cost.
Taxes, insurance, mortgage insurance, HOA dues, and assessments must also be included.
Example of the New Rental-Income Calculation
Suppose the supported market rent for your current home is $2,500 per month.
The lender would calculate:
$2,500 × 75% = $1,875
Now assume the property’s complete monthly housing expense is $1,700.
The calculation would be:
$1,875 qualifying rent − $1,700 housing expense = $175
Because 75% of the supported rent exceeds the complete housing expense, the rental income may offset the entire $1,700 payment.
However, the additional $175 cannot be added to your qualifying income.
For a departing residence, positive rental income is limited to offsetting the housing expense.
Now assume the same property has a complete monthly housing expense of $2,000:
$1,875 qualifying rent − $2,000 housing expense = −$125
In this example, the lender would include the $125 monthly shortfall in the borrower’s debt-to-income ratio.
Can the Rent Increase Your Purchasing Power?
Potentially—but not by creating additional positive income.
The supported rental income may increase your purchasing power by reducing or eliminating the effect of the departing home’s payment on your debt-to-income ratio.
If the departing home has a $2,000 complete monthly expense and no rental income can be used, the lender may have to count the entire $2,000 obligation against you.
If eligible rent reduces that obligation to only $125, your debt-to-income ratio may improve substantially.
However, if the adjusted rental income is greater than the housing expense, the excess cannot be added to your other qualifying income.
Are Six Months of Reserves Required?
If the borrower has less than 12 months of property-management experience, Fannie Mae requires six months of reserves for the departing residence’s PITIA obligation.
Reserves are eligible funds remaining after the borrower pays the down payment, closing costs, and other required expenses for the new purchase.
Depending on the account and applicable guidelines, reserves may come from:
Checking accounts
Savings accounts
Money-market accounts
Eligible investment accounts
Eligible retirement accounts
The six-month requirement for the departing residence is in addition to any reserves required because the borrower owns multiple financed properties.
A borrower with at least 12 months of property-management experience may not be subject to this specific additional six-month requirement. However, other reserve requirements may still apply based on the complete loan scenario and underwriting findings.
Do You Need Previous Landlord Experience?
Previous property-management experience is not necessarily required to use the new guideline.
However, a borrower with less than 12 months of experience must meet the six-month departing-residence reserve requirement.
That distinction allows a first-time landlord to potentially use the home’s supported market rent while providing additional financial protection against vacancy and unexpected expenses.
When Does the New Fannie Mae Rule Take Effect?
Fannie Mae announced the updated rental-income policies on September 2, 2026.
Lenders are encouraged to implement the changes immediately.
The rules become mandatory for loans with application dates on or after November 1, 2026.
The effective date is based on the mortgage application date—not necessarily the date the borrower closes on the new home.
Before the mandatory date, individual lenders may adopt the guidelines at different times.
The official implementation schedule is included in Fannie Mae Selling Guide Announcement SEL-2026-08.
Who Could Benefit From the Change?
The updated guidelines could help homeowners who:
Want to purchase another primary residence
Would prefer to keep their current home as a rental
Do not want to secure a tenant before buying the next property
Need potential rent to offset the current home’s payment
Have sufficient funds to satisfy the reserve requirements
Want to begin building a rental-property portfolio
Need more flexibility when coordinating their move
Have a favorable existing mortgage they would prefer to keep
Keeping a favorable mortgage rate can be an additional benefit, but it is not the primary purpose of the guideline.
The main benefit is the ability to document rental potential through market data instead of depending on a signed lease.
Does Your Current Interest Rate Transfer to the New Home?
No.
The existing mortgage and interest rate remain attached to your current property.
If you retain that home, you may be able to keep its existing mortgage while converting the property into a rental.
The home you are purchasing would have a separate mortgage based on the loan programs, interest rates, and terms available for that transaction.
The new Fannie Mae guideline does not create a portable mortgage. It may simply make retaining the current property easier by allowing supported market rent to offset some or all of its monthly housing expense.
What Should You Evaluate Before Becoming a Landlord?
Easier mortgage qualification does not automatically mean keeping the home is the right financial decision.
Before converting your residence into a rental, evaluate the following factors.
Realistic Rental Income
An online rental estimate is not a guarantee of what a tenant will pay.
The lender must support the market rent with acceptable comparable properties. You should also evaluate the condition, location, amenities, and competition surrounding your home.
Complete Monthly Expenses
Look beyond the principal-and-interest payment.
Consider:
Property taxes
Landlord insurance
HOA dues
Property management
Maintenance
Repairs
Vacancy
Landscaping
Pest control
Capital improvements
Leasing expenses
The underwriting calculation is designed to determine mortgage eligibility. It is not a complete investment analysis or guarantee that the home will produce positive cash flow.
Emergency Savings
Even if you satisfy the lender’s reserve requirement, consider whether you are personally comfortable carrying two homes during a vacancy or major repair.
Property Management
Decide whether you will manage the property yourself or hire a professional property-management company.
Professional management can reduce the owner’s workload, but the fee will affect monthly cash flow.
Insurance Coverage
Your existing owner-occupied homeowners policy may not provide appropriate coverage after the property becomes a rental.
Speak with a qualified insurance professional about landlord or dwelling coverage before a tenant occupies the home.
HOA Restrictions
Some associations restrict rentals, limit the percentage of units that may be rented, impose minimum lease terms, or require owners to register tenants.
Review the association’s rules before committing to the strategy.
Tax Consequences
Converting a primary residence into an investment property can affect depreciation, deductible expenses, rental-income reporting, and the tax treatment of a future sale.
Consult a qualified tax professional about your specific situation.
Is This the Same as Buying Before Selling?
It is one possible version of buying before selling.
Some buyers purchase the new home and then sell the previous property shortly afterward. Others keep the old home permanently as a rental.
The best strategy depends on your income, equity, available savings, current mortgage, expected rent, and long-term goals.

Does the New Rule Guarantee Approval?
No.
The ability to document market rent is only one part of the mortgage approval.
The lender must still evaluate:
Credit history and credit scores
Employment and qualifying income
Current housing history
Debt-to-income ratio
Funds for the down payment and closing costs
Required reserves
Number of financed properties
Property value
Appraisal requirements
Desktop Underwriter findings
Applicable lender overlays
Borrowers interested in traditional financing can learn more about conventional home loans.
Homeowners or investors whose circumstances do not fit standard conventional requirements may also want to review available non-QM home loan options.
Should You Keep Your Current Home or Sell It?
There is no universal answer.
Selling the current property may:
Release equity for the new home
Reduce the required down payment
Eliminate the responsibility of owning two homes
Simplify mortgage qualification
Reduce financial risk
Keeping it as a rental may:
Preserve a favorable existing mortgage
Create a long-term rental asset
Allow continued equity growth
Produce future rental income
Help build a real estate portfolio
The decision should be based on the complete financial picture—not only the current interest rate or estimated monthly rent.
Planning to Turn Your Current Home Into a Rental?
