Quick assumptions
Mix percentages are studio/1BR/2BR/3BR(/4BR). Quick mode sets roughly one manager's unit per 120 units (edit in Detailed). Rents assume every unit rents at the max for the average AMI. Budget is split by typical shares of cost; on 4% deals bonds are sized to the bond test plus a 2% cushion.

Unit mix & rents
| Beds | Units | SF | AMI % | Util. allow. | Rent cap | Max gross | Net rent |
|---|
SF is net rentable per unit (used for the square-foot cost build-up and per-SF metrics). Rent cap: optional market ceiling on net rent. AMI tiers should be 20–80% in 10% steps for income averaging.
Uses (development budget)
| Line | Amount | Eligible % | Bond-test % |

Eligible % drives tax credit basis. Bond-test % is depreciable basis + land (the denominator for the bond test).

Sensitivity – remaining gap
Each row moves one assumption and holds the rest. Numbers in parentheses are surpluses.
Max gross rents
Gross rent = 30% of the income limit for the imputed household (1.5 persons per bedroom; studio = 1). Subtract utility allowance for net rent. Existing projects may use higher held-harmless limits. Verify against HUD and your state agency before relying on these.
