Down payment vs cash flow, buy box, tenant screening, and cap rate framing for Houston rental investors.
The property you fall in love with and the property that pays for itself are not always the same property. Run the cash-flow math first, then go looking, not the other way around.
A bigger down payment lowers your monthly debt service and improves cash flow. A smaller down payment improves your return on the cash you put in, if the numbers still work. Neither is automatically right. It depends on what you are optimizing for.
Model your monthly numbers, mortgage, property tax, insurance, and a maintenance reserve, against realistic rent for the area before you commit to a down-payment level. Ask your lender for investment-property terms specifically, since they differ from owner-occupant terms.
Write down your criteria before you start touring: price range, property type, condition tolerance, and target neighborhood characteristics like commute access and housing stock age. A written buy box keeps you from drifting toward whatever you saw last.
Credit history, income verification, rental history, and background checks are standard practice, run consistently for every applicant. Consistency is also what keeps your screening process compliant with Fair Housing law.
Cap rate lets you compare properties on a like-for-like basis. It does not account for financing, appreciation potential, or your own risk tolerance, so treat it as a screening tool, not a final verdict.
