- Parcels sold on future upside.
- Land that may take time to stabilize, improve, or re-categorize.
- Deals where the hold only looks cheap because the timeline is optimistic.
Secure tool
Server-side carry-cost reality check
This version keeps the hold logic behind a Cloudflare Function instead of exposing the modeling rules directly in page JavaScript.
That makes copying your exact framing, thresholds, and interpretation materially harder than just opening DevTools on a public tool.
The original carry-cost tool exposes its logic in browser JavaScript. This secure version keeps the actual interpretation and pressure framing off the public page.
Enter the hold assumptions and run the check.
If the hold still looks tolerable, move the tract into the full due-diligence checklist and county-specific context pages.
This is the same architecture as the secure parcel screen and secure homesite pressure test: browser handles form UI, server handles the actual judgment logic.
