Screen the split. Where flipping becomes development

The biggest value lever in land is the split: a parcel that's worth more carved into conforming lots than sold whole. But the screen sits on a knife's edge, because the two numbers that decide it, the code's minimum lot size and the parcel's net usable area, are exactly the numbers an AI will happily invent. The move is a constraints-and-negatives screen that quotes the minimum lot size from the pasted zoning, states the gross-to-net deductions (roads, setbacks, easements, unbuildable slope or wetland) as a checklist, and sets up the yield as net area divided by minimum lot size, tagged for you to compute, never multiplied out. The hard negatives do the work: never invent a code minimum, a frontage requirement, or a density bonus; never treat gross acreage as buildable; and never predict that the split gets approved or how long it takes, because subdivision and rezoning approval is a discretionary local decision no model can call. The output is a go / no-go SCREEN, does the math even plausibly support a split worth diligencing, plus the questions for the planning department that turn the UNKNOWNs into a real yield.
Could I split this parcel into more lots? Here's the zoning and the parcel size. [paste the zoning text and parcel specs]
2 · Your turn. You write the prompt
You're looking at a 6-acre parcel and wondering if it splits. You paste the zoning excerpt ('R-1: minimum lot size 1 acre; minimum street frontage 100 ft per lot') and the parcel specs (6 gross acres, one existing access point, a recorded 20-ft utility easement along the east line, and a note that the back 1.5 acres are steep and likely unbuildable). You want a go/no-go split screen with the yield set up, without the AI inventing a code number or telling you the split will be approved. Write that prompt.
Remember: the AI sees only your prompt, not this page. If the situation isn't in your prompt, it doesn't exist.
