How These Calculators Work

Methodology: formulas combine standard amortization math, cash-flow arithmetic, and simple return ratios.

Inputs: purchase price, rates, rents, expenses, rehab assumptions, and timeline choices.

Datasets: baseline home-price bands, mortgage-rate ranges, rent bands, and property assumption defaults.

Limitations: local regulation, tax treatment, and true operating costs can materially change outcomes.

Intended use: quick screening and scenario planning before deeper underwriting.
