What this calculator is designed for
Evaluate a single property or a building with several unit types.
This is a flipping analysis. Rent inputs help establish an exit value; they do not create a rental-hold cash-flow forecast.
Single-property flips
Use the calculator to analyze buying, renovating, and reselling a property. Enter a manual exit price when that is the appropriate basis for the resale analysis.
Multifamily value-add projects
Model up to 10 unit types, with unit counts, renovation costs, rent assumptions, and occupancy informing the post-renovation valuation.
Acquisition & renovation costs
Build the initial investment from the property details.
Purchase price and financing
Enter the acquisition price and any financing used in the deal to establish the initial investment requirements.
Bottom-up renovation budget
Calculate renovation costs from the number of units in each type and the renovation cost per unit.
Value-add drivers
Translate renovation assumptions into post-renovation NOI.
These operating assumptions support the exit valuation for an income-producing property.
Current property profile
Enter the unit types, unit counts, current rent roll, and occupancy assumptions.
Post-renovation rents
Set the expected increase in rent per unit after the renovation.
Post-renovation occupancy
Enter the expected new occupancy to calculate the post-renovation gross rental income.
Operating expenses and NOI
Enter the new operating expenses to determine post-renovation net operating income.
Two exit-price options
Choose the exit valuation approach that fits the property.
NOI and exit capitalization rate
Use post-renovation net operating income and an exit cap rate to calculate the property’s exit value.
Manual resale price
Override the NOI-based valuation by entering an exit price directly for the building or property.
Deal-level outputs
See what remains after debt and accrued interest are repaid.
Net exit proceeds
The calculator assumes debt and accrued interest are paid off at exit, then calculates the remaining proceeds.
Return on investment
Compare net exit proceeds with the initial investment required to evaluate the deal’s ROI.
Equity multiple
Review the equity multiple alongside ROI to assess the relationship between the invested equity and the exit proceeds.
Pre-tax net profit
Review the included pre-tax net profit calculation as another measure of the deal’s financial outcome.
Getting started
Move from the renovation plan to the expected return.
Set the purchase and renovation budget
Enter the purchase price, financing assumptions, unit counts, and renovation cost per unit.
Define the value-add assumptions
For an NOI-based exit, enter current rents and occupancy, expected rent increases, post-renovation occupancy, and operating expenses.
Choose the resale valuation
Enter an exit cap rate to use post-renovation NOI or override the valuation with a manual resale price.
Review the deal economics
Inspect debt and accrued-interest payoff, net exit proceeds, pre-tax profit, ROI, and equity multiple.

Questions before you start
A few useful details.
Can I use this for a house that I plan to renovate and sell without renting it?
Yes. This calculator is designed for flipping. You can enter a manual exit price; the rent inputs are used to help inform an NOI-based resale value.
Does this forecast rental income during a long-term hold?
No. The rental assumptions support the exit valuation. This is a renovation-and-resale calculator rather than a rental-hold forecast.
How many unit types can I model?
The calculator supports up to 10 unit types, allowing it to work for a single property or a multifamily building.
How is the renovation budget calculated?
It is built from the number of units in each type and the renovation cost per unit.
How is post-renovation value calculated?
The model uses post-renovation NOI and an exit cap rate, with an option to override that result using a manually entered exit price.
What happens to the debt at exit?
The calculator assumes debt and accrued interest are paid off when the property is sold, then calculates net exit proceeds.
Which return outputs are included?
Outputs include ROI, equity multiple, and pre-tax net profit, based on the acquisition, renovation, financing, and exit assumptions.
Which model should I look at for a growing flipping business?
See the Fix and Flip Scaling Model linked above for a dedicated 10-year planning model. You can also contact Jason about custom modifications.
