Start with ARV to estimate a finished value. Use the 70% rule for a quick screen, MAO to include a wholesale fee, or the wholesale calculator to build an itemized buyer budget. The flip calculator models the project; flip ROI focuses on the return.
For a property you plan to keep, compare rental cash flow and cap rate. BRRRR follows your cash through a refinance. Creative Finance tests the payment structure, while Home Appreciation explores a value assumption over time.
Every tool includes editable assumptions, a transparent formula, a worked example, and answers to common questions. Defaults are illustrative; replace them with your own property research and actual costs.
