Rent-versus-buy method and scenario checks

The comparison combines recurring cash flow, upfront and exit costs, the holding period, home-value assumptions, maintenance, and the alternative use of cash. Monthly affordability and projected long-term net worth should be reviewed separately because a favorable modeled return can still create a strained budget.

Use written rent terms, a lender Loan Estimate, property-specific taxes and insurance, and a realistic repair reserve. Run shorter and longer holding periods plus a flat-price case. The model cannot predict a sale price, repair timing, rent renewal, insurance availability, or how long the household will stay.
