The difference
Most calculators stop at the answer.
DealCooker helps you change it.
When a modeled deal misses DealCooker’s built-in cash-flow or DSCR thresholds, the workout can test a lower purchase price and, when applicable, a larger down payment. Cash-deal and flip workflows use their own strategy-specific target logic.
- 01Choose the strategy and enter the deal.
- 02See whether the current inputs clear the model’s thresholds.
- 03Compare any supported price or equity scenario with the original.
One property. More than one path.
Underwrite the strategy you’re actually considering.
Every strategy has its own revenue, expense, debt, and exit logic—connected to one acquisition model.

Change the strategy.
