The working tools I utilize

Day to day I have built AI into my own recurring work, and these are the pieces of it worth handing over. Below is the set, free to take: run them here, or download and make them yours. I would rather they got used than sat unopened on a hard drive.

Every figure on this page is invented.

The Underwriting Model

A full acquisition model for a value-add apartment deal.

Rent roll by unit type, the T-12 against the pro forma, rent growth and loss to lease, a renovation program, the loan sized by its binding test, the exit, levered and unlevered IRR, equity multiple and cash on cash, 3 sensitivity grids, and the depreciation and tax view.

Debt Sizing and Refinance

Every loan has 3 ceilings. Only one of them binds.

The loan sized by LTV, DSCR and debt yield with the binding test named, rate and amortization scenarios, interest-only periods, the schedule and balloon, prepayment by step-down or yield maintenance, and a refinance at the end of the hold.
