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.
Example use cases
Ground-up apartment development feasibility
“I'm looking at a 150-unit multifamily development with $35M in total project costs. Can you underwrite it with an 18-month construction period using S-curve draws, a 5.75% construction loan rate, 10-month lease-up, construction-to-perm refi at 5.25%, a 7-year hold, and a 5.0% exit cap rate? I need yield on cost, profit on cost, IRR, and MOIC.”
Comparing S-curve vs straight-line draw impact
“Model a 300-unit ground-up multifamily deal with $60M total cost and a 30-month construction period — run it with straight-line draws at a 6.5% construction loan rate, 14-month lease-up ramp, then refi into a perm loan at 5.8%, hold for 5 years, and sell at a 5.5% cap rate. Show me the capitalized interest and development yield on cost.”
Multifamily development exit timing analysis
“Underwrite a 120-unit apartment development with $28M in total costs, 20-month construction with S-curve draws, 6% construction loan, 8-month lease-up, construction-to-perm refi at 5.4%, and model returns at both a 3-year and 7-year hold exiting at a 4.75% cap rate — what's the IRR and MOIC at each hold period?”
Technical details
Endpoint
POSThttps://financial-analyst.ai/mf-dev/underwrite?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
