Built the way buyers underwrite

These models come out of transaction work: pricing development pipelines, sizing debt, and testing sellers' numbers. They are built to hold up when a lender, investor or buyer opens them.

Audit every cell

Fully unlocked, no macros, no hardcodes in calculations, and a checks tab that ties everything out.

Documented

A PDF guide explains every input, typical ranges, where to find the data, and how to read the outputs.

Kept current

Tax credit rates and adders are inputs, and updates are free for 12 months.
