Can I Buy My Next House and Use Rent From My Current House to Help Me Qualify?

Quick Answer

Yes, rent from your current home may help you qualify to buy your next house. The amount that counts depends on the loan rules, accepted rent documents, and the current home’s costs. Keeping your Round Rock home as a rental still requires a full review of your finances.

Key Takeaways

• Expected rent and rent accepted for approval can differ.

• The current home’s monthly costs still affect the plan.

• A rental plan needs room for repairs and empty months.

• Approval and a comfortable household budget are separate checks.

How can rental income help?

A departing residence is the home you leave when you move into your next main home. If you keep that home and rent it out, accepted rental income may help cover its housing expense in the loan review.

The old home’s debt does not disappear when a tenant moves in. The lender, the company making the loan, reviews the rental income and housing costs under the applicable rules. Fannie Mae guidance

What would the numbers look like?

Under Fannie Mae’s updated departing-home rules, the calculation starts with 75% of supported rent. Assume supported monthly rent of $2,800:

• $2,800 × 75% = $2,100.

• Assume total monthly housing costs of $2,300.

• The remaining $200 counts against qualification.

The housing total includes principal, interest, taxes, insurance, and applicable association dues. Under this updated rule, a positive result offsets the old home’s housing expense; it does not add extra qualifying income. These figures are an example, not a Round Rock rent estimate.

What should you check before shopping?

As of September 2026, Fannie Mae has announced new rules that lenders may adopt early and must use for applications dated December 1, 2026, onward. Confirm the rules for your file before relying on projected rent. Fannie Mae announcement

For your own budget, picture an empty month followed by a repair. Would keeping both homes still feel comfortable? Moving costs, lawn care, and time spent handling the rental belong in that review.

Frequently Asked Questions

Is a signed lease enough?

Not under Fannie Mae’s updated departing-home rules. Those rules require market-supported rent documentation rather than a lease to establish the rental amount.

Should I plan for repair costs?

Yes. A rental budget should leave room for repairs and time without a tenant. The rent you hope to receive is not a promise that every month will go as planned.

Does loan approval mean keeping both homes fits my budget?

No. Approval is one checkpoint. Your own budget also needs room for moving, upkeep, and the way your family wants to live.
