The operator's tool

The Boston Investor Deal Analyzer.

Paste in any rental’s numbers and see what it actually pays you — cap rate, cash-on-cash, real cash flow, and what a lender will think. The same math our operators run before every offer.

Remember: cash flow is only one of the four ways this pays you. In Boston it is often thin on purpose — the real return hides in appreciation, loan paydown by your tenant, and tax benefits. A modest cash-on-cash here can still be a strong deal once you add the other three. That is Chapter 1 of the Field Guide.

Bring one deal. We’ll run all of it with you.

This tool does the cash-flow math. An operator does the rest — the reno budget priced by our GC, the real operating costs from 1,500 doors, and where the tax moves fit. Twenty minutes, no pitch.
