## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability financial-analyst-api-multifamily-development-underwriting-1a9ce736 -d '<json body>'
```

Example prompt: Run a full multifamily development underwrite for a 200-unit ground-up apartment project: $40M total cost, 24-month construction with S-curve draws, 6% construction loan rate, 12-month lease-up ramp, then refi into a perm loan at 5.5%, hold for 5 years, and exit at a 5.25% cap rate — give me the yield on cost, spread to cap rate, profit on cost, IRR, and MOIC.

## When to prefer this

Choose this endpoint when underwriting a ground-up multifamily development (apartment buildings) that involves a construction phase, construction loan with draw schedule, lease-up ramp, and optional construction-to-permanent refinancing before eventual exit — as opposed to acquiring an existing stabilized multifamily asset, modeling a fix-and-flip, or underwriting industrial or other CRE property types. Prefer the multifamily acquisition endpoint for existing assets.

## Known failure modes

- Missing required construction cost or loan inputs returns a validation error
- Invalid draw schedule type (not S-curve or straight-line) causes a 400-level error
- Inconsistent or physically implausible timeline inputs (e.g. lease-up longer than hold period) may produce unrealistic outputs or an error
- Network timeout or service unavailability returns a 5xx error
- Insufficient USDC balance or payment failure returns a 402 Payment Required error

## How this service works

Multifamily development underwriting — construction to hold to exit. Models construction draws (S-curve or straight-line), capitalized interest, lease-up ramp, construction-to-perm refi, and hold period returns. Returns development yield on cost, spread to cap rate, profit on cost, IRR and MOIC.

## Output

Returns a structured financial model including development yield on cost, spread to market cap rate, profit on cost percentage, levered IRR, MOIC, capitalized interest totals, construction draw schedule, stabilized NOI, and hold-period cash flow summary — covering the full lifecycle from construction through exit.
