Why it matters
This question still needs a dated cash walk: How should a TI allowance sit in a lease model?
A short recap cannot carry a year-by-year example.
The rank can flip when this input moves.
A finance lead will ask which line changed the number.
How it works
- Put the numbers on one year list with rent.
- Hold the other assumptions still.
- Use one named method to shrink or spread the cash.
- Show a second path so the gap is visible.
- Keep the rate on the same page as the pick.
Formula in words. Model-TI uses one shared rate and one dated list.
| Input | Meaning |
|---|---|
| Start rent | First-year rent before extras |
| Extras | CAM, tax, or insurance the tenant still pays |
| Credits | Free rent or build-out money |
| Term | How many years the cash list runs |
| Discount rate | How hard later cash is shrunk |
Worked example
Here is a teaching sample. It is not customer data and not a result from a live client.
| Metric | Path A | Path B |
|---|---|---|
| Start rent | $39,000 | $36,270 |
| Year-1 extras | $8,000 | $8,560 |
| Year-1 credit | $18,000 | $9,900 |
| Sample NPV | $338,189 | $329,305 |
| Year | Rent | Extras | Credit | Cash out | Value today |
|---|---|---|---|---|---|
| Year 1 | $39,000 | $8,000 | $18,000 | $29,000 | $26,852 |
| Year 2 | $40,170 | $8,240 | $0 | $48,410 | $41,504 |
| Year 3 | $41,375 | $8,487 | $0 | $49,862 | $39,582 |
| Year 4 | $42,616 | $8,742 | $0 | $51,358 | $37,750 |
| Year 5 | $43,895 | $9,004 | $0 | $52,899 | $36,002 |

| Year 10 | $50,886 | $10,438 | $0 | $61,324 | $28,405 |
| Sample NPV | — | — | — | — | $338,189 |
Sample NPV for Model-TI sample is about $338,189. A second path lands near $329,305.
Year 1 of Model-TI sample has rent of $39,000.
Shared building cost is $8,000.
A credit of $18,000 lowers the cash you pay that year.
Cash out this year is about $29,000. Year one carries the Model-TI sample credit.
Later cash gets a shrink for time. At 8 percent, year 1 is worth about $26,852 today.
Next, year 2 rent is $40,170.
Assumptions
- The Model-TI sample uses one visible 8 percent rate.
- Credits hit in year one unless the page says otherwise.
- Both options share the same extra basis.
- No percentage rent sits in this teaching walk.
Edge cases
A mid-year start needs a stub period, not a fake full year.
A credit that pays later must move to that later year.
A cap on extras changes the later risk, not the first sticker.
Common mistakes
- Copying a nearby page and only changing the title.
- Hiding the rate.
- Dropping extras on a net path.
- Calling the teaching sample a live client result.
Decision implications
A TI credit belongs in the year it funds work. It is not a rent cut in every later year.
If the gap is thin, show a second rate before anyone picks.
If one path wins only from a mistimed credit, rebuild the list.
