Common Questions

Frequently Asked Questions

Everything you need to know about the Rental Cash Flow Analyzer

Cap rates vary significantly by market and property type. In major metros, 4-6% is common for stabilized properties. In secondary markets, 7-10% is more typical. The calculator helps you compare deals within your target market rather than chasing a universal number.

Cap rate measures the property return without financing (NOI / Purchase Price). Cash-on-cash return measures the return on your actual cash invested including leverage (Annual Cash Flow / Total Cash Invested). Leverage can amplify your cash-on-cash return above the cap rate.

Most investors use 5-8% for single-family rentals in strong markets and 8-12% for multi-family or weaker markets. The calculator lets you adjust this based on your local conditions and property type.

Yes. The calculator includes a capex reserve line item (typically 5-10% of gross rent) for roof, HVAC, appliances, and other major replacement items. Skipping capex reserves is how investors get blindsided by large unexpected costs.

Property taxes, insurance, property management, maintenance, capex reserves, vacancy allowance, HOA fees, and utilities (if owner-paid). Every major operating expense is modeled individually.
