This is an early, invite-only beta. Expect rough edges and possible bugs. Your entries autosave to this browser as you work, so closing or refreshing the page won't lose your progress — there's nothing to sign in to, and nothing is saved on our end. Use the Feedback button in the corner any time — it directly shapes what gets fixed next.
This is a preliminary screening tool, not legal, zoning, architectural, engineering, appraisal, tax, lending, or investment advice. It uses assumptions you provide — buildable square footage, rents, and construction costs are entered by you, not determined by this tool. It produces a return analysis, a transparent record of your assumptions, and a next-diligence checklist.
What this tool does
- Runs a deterministic development pro forma from your inputs
- Tracks the source and verification status of every assumption
- Generates a plain-English screening outcome and diligence checklist
What this tool does not do
- Determine zoning or legally buildable square footage
- Estimate rents or construction costs automatically
- Provide legal, financial, or investment advice
