What documents should I ask for when buying a rental portfolio?

Ask for the rent roll, signed leases, at least twelve months of rent collections, the tax account for each home, current insurance policies, HOA contacts and dues, repair records and the title commitment. Verify each against its original source.

How to Evaluate a Houston Rental Portfolio

1. Start with the rent roll, then prove it

The rent roll lists each home, its rent, lease start and end dates and the deposit held. Ask for copies of the signed leases and compare every line. Month-to-month tenancies, recent renewals and rents far above or below the others are the lines to question.

2. Ask what was collected, not what was scheduled

Scheduled rent is what the leases say; collected rent is what reached the bank. Request at least twelve months of collections or deposits and note late payments, concessions and vacant months. A portfolio priced on scheduled rent alone overstates income.

3. Rebuild the operating expenses yourself

Use the appraisal district’s tax records for each home, fresh insurance quotes, HOA dues from the association, a repair and maintenance allowance, management (even if you plan to self-manage) and vacancy. In Harris County, check each account on HCAD; MUD and city taxes differ street by street.

4. Inspect every home

Roof age, HVAC, plumbing, foundation and drainage decide the first-year budget. Inspect occupied homes with proper notice to residents, and price deferred maintenance into your offer.

5. Understand the title and the debt

Portfolios are often owned by different entities or financed together. The title commitment will show liens, and any loan that covers several homes may need a lender’s release before one home can be sold on its own.

6. Model the deal both ways

Keep the property’s operating performance (NOI) separate from your financing. Then test financing, vacancy and expense changes with the rental cash flow calculator and the DSCR calculator.
