PrePerc answers the single biggest question raw land buyers have — before they call an agent. A percability score for any parcel, from public data, in seconds.
A perc test costs $500–2,000 and takes 2–6 weeks. Most parcels never get one. So buyers skip them. Sellers never get the call. The question — can I build here? — goes unanswered.
PrePerc replaces silence with signal.
Soil type, slope, water table depth, bedrock depth, flood zones, wetlands — all from NRCS, USGS, FEMA, and USFWS.
A weighted model that predicts perc suitability. Not a substitute for a certified test — a pre-filter that costs pennies.
A one-page report per parcel. Green = go. Yellow = maybe. Red = get a real test before you invest serious time.
This is an algorithmic estimate based on public data. Always verify with a licensed perc test before purchase.
No. A real perc test is required for permits. PrePerc is a pre-filter — it tells you whether a parcel is worth the time and money to get a real test.
Starting with TN and NC (your target markets from Landgrid). More counties as we scale.
The model is built on SSURGO data at 1:12,000 to 1:24,000 scale — appropriate for pre-purchase filtering but not for engineering. We validate against known perc test results as we get them.
Yes. Agent tier includes an embeddable widget and API access. A "PrePerc Verified" badge on your listings means one less question for buyers.
No. Everything comes from public remote sensing and soil survey data. No field visit required.
We're launching with TN parcels first. Drop your email and we'll notify you when your county is live.
