How it works

Four numbers in, a decision out.

Seven screenshots, photographed from the running product by the build itself.

The condition panel: five system sliders pricing a repair estimate

Seven exits ranked by fit with the arithmetic shown

Advanced mode: the assumptions the arithmetic runs on

The sensitivity grid: profit when ARV and repairs are wrong

The offer view: six levers, your cost and how it reads to the seller

The land desk: a parcel drawn to scale with what it becomes as a finished lot standing on it

The dashboard: twelve instruments in the rail, eight at full size, and every property with its spread

Four jobs, one sheet.
