Cambridgeport, Cambridge MA — Feasibility tools for Steve Kaiser's legacy preservation project.

Tool A — Base case

Rental hold model

Perpetual affordable hold aligned with Steve's will. AMI tiers 50-130%, concession spread, year-by-year cash flow with Steve's transition modeled, and a full glossary of terms. The base case for all planning.

Tool B — Alternative

Condo sale model

What-if analysis: sell 1, 2, or 3 units as condos. Deed-restricted vs. market pricing up to $2.5M, HOA governance, KPI dashboard, and a glossary explaining every metric. For succession planning and comparison.

Tool C — Decision Report

Decision report

Three-scenario comparison (conservative, moderate, aggressive) with verdicts, cash flow milestones, Steve's before/after transition analysis, construction risk stress tests, and a 10-step Cambridge action plan. The artifact you send to the lawyer.
