Interactive Scenario Modeling

Adjust assumptions in real time to test different scenarios and see how sensitive your savings are to each variable.

How Scenario Modeling Works

Every input field in the visualizer triggers instant recalculation. Adjust purchase prices, rent levels, vacancy rates, mortgage rates, and analysis periods. All charts update in real time via AJAX.

  • Two house hack modes: Multi-Unit (duplex/triplex/fourplex) and Rent by Room (single-family)
  • Adjust any variable and see all 5 charts update instantly
  • Analysis period selector: 5, 10, 15, 20, or 30 years
  • Save unlimited scenarios per property for easy comparison

Answer the "What If" Questions

What if vacancy is 10% instead of 5%? What if mortgage rates rise to 7.5%? What if rents grow 4% per year? Scenario modeling lets you stress-test every assumption.

  • Test optimistic, realistic, and pessimistic scenarios
  • Save each scenario with a descriptive name
  • Compare properties by switching the property selector
