Three IRR sensitivity tables
See how vacancy interacts with the exit and financing assumptions.
The current template includes these three comparisons. Each table varies a pair of assumptions to show the resulting IRR under the modeled deal.
Vacancy vs. cap rate
Compare vacancy assumptions against the exit cap rate to review how operating occupancy and the sale valuation assumption affect IRR.
Vacancy vs. leverage rate
Compare vacancy assumptions against the amount of leverage used in the acquisition to review the effect on IRR.
Vacancy vs. interest rate
Compare vacancy assumptions against the financing interest rate to review the effect on IRR across different borrowing-cost scenarios.
Acquisition and operating inputs
Build the analysis around the property and the proposed deal.
Enter the acquisition, financing, rent, expense and exit assumptions for the real estate opportunity you are evaluating.
Acquisition costs
Set the acquisition costs used to establish the investment’s starting cash requirements.
Debt financing
Include debt financing when applicable and set the financing assumptions for the deal.
Starting rent and rent growth
Enter the starting rent and rent-growth assumptions used in the operating forecast.
Operating expenses and growth
Define starting operating expenses (OPEX) and the expense-growth assumptions over the analysis period.
Exit month
Choose the exit month within an analysis timeframe of up to 20 years.
Exit cap rate
Set the exit cap rate used in the sale analysis and compare alternative cap rates through the sensitivity table.
Cash flow, coverage and returns
Review the cash flow behind the IRR.
Analyze a holding period of up to 20 years and review the operating and financing results alongside the sensitivity tables.
Monthly and annual cash flow
Review cash flow in both monthly and annual views to follow the investment through the modeled holding period.
Monthly and annual DSCR
See the debt service coverage ratio (DSCR) displayed for each month and year when reviewing the financing assumptions.
Inputs and sensitivity on one page
All inputs, monthly cash flow and sensitivity tables are together on one page, keeping the assumptions and their results close at hand.
Latest template update
Review the updated financing sensitivity tables.
The bottom two tables now compare vacancy against interest rates and vacancy against leverage rate. Watch the update video to review those changes.
How to use the template
Move from the base deal to a range of potential outcomes.
Set up the acquisition
Enter acquisition costs, financing if applicable, starting rent and OPEX, growth assumptions, exit month and exit cap rate.
Choose the sensitivity ranges
Define the range of vacancy, cap-rate, leverage and interest-rate assumptions you want to evaluate with the three tables.
Review the scenarios
Use the built-in Excel data tables to review IRR across the combinations of assumptions. Compare base, upside and downside cases relevant to the deal.
Read returns alongside cash flow
Review the IRR results with monthly and annual cash flow and DSCR. Identify the assumptions that most affect the investment and use those findings to guide further deal analysis.
Who this template is for
For real estate buyers, investors and deal analysts.
Acquisition analysis
Build a cash flow view of a proposed property acquisition and examine the return sensitivity to vacancy, financing and the exit cap rate.
Scenario comparisons
