Buying a Rental Property With Existing Tenants
An occupied rental can provide immediate income, but the existing leases and tenant obligations should be reviewed before closing.
Start with signed leases, not the listing
A listing might advertise a potential rent of $2,200 while the current tenant has a signed lease for $1,850 through next summer. The buyer may be bound by the lease after closing, subject to applicable law and contract terms. Obtain every lease, amendment, renewal, concession and written side agreement. Confirm the actual payment schedule and whether any tenants are behind.
Verify deposits and prepaid rent
Security deposits and prepaid rent may need to be accounted for and transferred or credited at closing under applicable law. Ask for a tenant ledger showing deposits, last month's rent, concessions, unpaid balances and any pending disputes. Do not assume the seller's operating statement reflects every obligation. A property manager or real estate attorney can help verify local requirements.
How underwriting treats existing leases
Fannie Mae's September 2026 subject-property rental-income guidance requires applicable rent schedules and fully executed leases when leases transfer to a purchaser. Market rent evidence must reasonably support the lease amount or additional analysis may be required. The rent a seller hopes to obtain after renewal is not necessarily the rent a lender can use for qualification today.
A cash-flow example
Suppose a duplex collects $1,700 from one unit and $1,900 from the other, but the listing's pro forma assumes $2,100 for both. That is $600 per month of projected revenue not currently being collected. Over a year, the gap is $7,200 before expenses. A prudent buyer should underwrite current contractual rent and separately consider the uncertainty of future rent increases.
Inspect with tenants in place
Coordinate access lawfully and respectfully. Review condition, maintenance records, open work orders, insurance claims and any habitability concerns. The tenant's rights and lease terms may limit inspection or renovation timing. An attractive cap rate on paper can disappear if deferred maintenance or turnover costs are underestimated.
Prepare for a smooth transition
Confirm who will notify tenants, where rent is paid after closing, how deposits transfer and who handles maintenance. Ask the lender for rental-income documentation requirements early so lease issues do not delay financing. The mortgage approval process does not replace legal review of tenant obligations.
Frequently asked questions
Can I raise rent immediately after buying?
Existing lease terms and applicable law may limit changes; seek local legal guidance.
Will a lender use the advertised market rent?
Not necessarily. Current leases and supported market-rent documentation may govern.
Do tenant deposits transfer to the buyer?
They generally require appropriate accounting under applicable law and closing documents.
Should I inspect occupied units?
Yes, using lawful access and qualified inspection professionals.
Can existing tenants help with mortgage approval?
Documented eligible rental income may help, subject to program rules.
The bottom line
An occupied rental can provide immediate income, but the existing leases and tenant obligations should be reviewed before closing. Compare written loan terms and property risks before committing.
