What the deal has to hit
Pick the measure and the target. Every lever below solves against it.
Untrended yield on cost 6.51%, target 7.00%: short 49 bps.
What each lever needs on its own
Each lever solved alone, tagged against the comps or a stated test.
Revenue
Rent increase, all types

Not supportedRent increase, 2 bed only
2 bed has the most room under its comp median. Rent against that median: at or under is Realistic, up to 5.0% over is Stretch.
$299 per 2 bed unit per month
11.7% on $2,550, comp median $2,578
Not supportedOther income
No comp for other income. Against today's $140 per unit: up to 15% more is Realistic, up to 35% Stretch.
$106 per unit per month
76% more than today's $140
Not supportedUnit mix shift, 2 bed to Studio

How the math works
Yield on cost is NOI over total project cost. For a target, NOI needed is the target times cost, and the cost allowed is NOI over the target.
Revenue levers close NOI needed less NOI. A rent dollar reaches NOI at 94.12%, after vacancy, concessions and credit loss; other income is carried in full.
Cost and land levers close cost less the cost allowed, dollar for dollar. Developer fee, contingency and financing are held where they are.
Units added at the same land carry the average NOI and the average non-land cost per unit, so each one yields 6.77% on its own cost. Adding units moves the deal toward that figure, never past it.
A development spread target is a yield on cost target of the 5.50% exit cap plus the spread.
Investor IRR is the LP IRR from the scenario rerun the sensitivity grid uses, solved by bisection. That run holds equity, loans and the sale date fixed, so cost, land and loan levers wait for the live model.
In a combination, levers apply in the order listed. Each lever's share is the change it makes on top of the levers above it, so the shares add to the combined result.
Tests without a comp use stated thresholds: other income up to 15% more, a mix shift up to 10% of a type, soft cost and contingency up to 10%, read Realistic.
