Start with the full cost.
Consider a hypothetical income-producing commercial property purchased for $20 million. The plan includes $2 million of improvements and $1 million for acquisition, financing, and other upfront costs. Total investment is $23 million, funded with $13 million of debt and $10 million of equity.
| Item | Assumption |
|---|---|
| Purchase price | $20.0 million |
| Improvements | $2.0 million |
| Acquisition, financing, and other upfront costs | $1.0 million |
| Total project cost | $23.0 million |
| Debt / equity | $13.0 million / $10.0 million |
| Annual interest-only debt service at 7% | $910,000 |
| Current annual net operating income | $1.3 million |
| Year-three stabilized annual net operating income | $1.6 million |
What does the business plan earn on its cost?
Net operating income (NOI) is property income after operating expenses and before debt service. At $1.6 million of stabilized NOI, the year-three yield on total cost is 6.96%: $1.6 million divided by $23 million.
At the assumed interest-only debt payment, that income provides 1.76 times debt-service coverage. Neither figure answers the entire investment question, but both help test whether the planned improvement justifies the capital it requires.
Then test the exit.
Assume a sale at the end of year five using $1.6 million of forward annual NOI, a $13 million loan payoff, and selling costs of 2%. Changing only the exit capitalization rate produces the following results.
| Exit cap rate | Property value | Equity sale proceeds |
|---|---|---|
| 6.0% | $26.67m | $13.13m |
| 6.5% | $24.62m | $11.12m |
| 7.0% | $22.86m | $9.40m |
| 7.5% | $21.33m | $7.91m |
Property value = forward NOI ÷ exit cap rate. Equity sale proceeds = value less 2% selling costs and the $13 million loan payoff. This table covers the sale only; operating distributions, taxes, and investor-level fees and allocations determine the full investor return.
Income and pricing can move against you together.
At a 6.5% exit cap rate, the base case produces $11.12 million of equity sale proceeds. If NOI is 10% lower and the exit cap rate is 7%, those proceeds fall to $7.16 million. The difference is almost $4 million, before considering operating distributions during the hold.
That is why the review needs to challenge both the income forecast and the exit pricing. A renovation plan that lifts rents can still disappoint investors if expenses rise, leasing takes longer, or the eventual buyer pays less for each dollar of income.
What should the investor verify?
Reconcile the rent roll, lease terms, and trailing operating statements. Test rents, occupancy, concessions, taxes, insurance, and recurring capital needs. Review the improvement budget and the cash needed while the work is underway.
Then compare the exit assumptions with relevant transactions and check the loan terms, reserves, fees, and distribution waterfall. The result may be a lower price, a different capital structure, a smaller improvement plan, or a decision to pass.
