Off-market land intelligence

We looked,
so you don't have to.

Every vacant parcel in your county — priced against its own sub-market, measured for a buildable pad with 1-meter LiDAR, screened for flood and wetland, and handed to you with a suggested offer and a mailing list.

No contract. County data refreshed quarterly.

The problem

A county average is not a price.

Two five-acre lots in the same county, four miles apart, are not the same asset. Price them off one county-wide $/acre figure and you will overpay for one and walk past the other.

How land is usually priced

  • One county-wide $/acre baseline, adjusted for size
  • Comps chosen by radius, not by whether the market is actually comparable
  • Terrain, if present at all, is a filter bolted on beside the price
  • A single number, with no stated error

How Sight Unseen prices it

  • Comparable home sales clustered into real sub-markets
  • A separate model trained per sub-market, then transferred onto vacant land
  • A conservative value that already carries the model's own error rate
  • Published accuracy per sub-market, so you can see what you are trusting
Buildable pad

“46% buildable” can still mean nowhere to put a house.

Most tools report the share of a parcel under a slope threshold. That number can't tell one usable bench from the same acreage scattered as unusable strips between drainages — both score identically.

We measure the largest connected area under your threshold, in acres, from 1-meter LiDAR elevation. It is the closest thing to will a house actually fit on one piece of this.

A 4-acre lot in Bastrop County measured 1.86 gentle acres — 46% buildable, and it screens clean. Its largest connected piece is 0.25 acres. That is a quarter-acre bench on a four-acre parcel: not enough to site a house and a septic field.

Both parcels report 1.86 gentle acres. Only one of them is a building site.

Hazards

Flood and wetland, before you mail.

Every parcel is checked against FEMA's Special Flood Hazard Areas and the National Wetlands Inventory — by polygon overlap, not centroid, because a centroid check misses roughly two in five affected parcels.

Anything flagged is held back from an automatic offer and marked REVIEW, with the zone, the share of the parcel affected, and what it means for financing. Never a silent rejection — plenty of good land sits in Zone AE.

“FEMA FLOOD ZONE AE — 86% of the parcel is in a Special Flood Hazard Area: mandatory flood insurance, and lenders will require an elevation certificate.”

Owner data

One owner, seven parcels, one letter.

Mailing addresses are parsed from whatever the county publishes — split fields, one combined blob, or a stack of numbered lines — then verified against a ZIP reference and de-duplicated by owner.

An owner holding seven parcels gets a single letter that names all seven, not seven letters. On a recent county that removed 34,765 duplicate letters from the mail run.

Second owners on jointly-held parcels are lifted onto their own line, so the envelope reads like a person addressed it.

Straight answers

How accurate is the price?

It varies by sub-market, and we publish the figure for each one rather than quoting a single headline number. Thin sub-markets get wide error bands and we say so on the report itself. If a county's sales data is too sparse to model honestly, we tell you instead of shipping a confident-looking guess.

Is the suggested offer safe to send without looking at the parcel?

It is a starting point, not advice. The suggested offer is a fixed percentage of a conservative value that already carries the model's error rate — it is built to be defensible, not optimal. Verify zoning, access and title before you close on anything. This is not financial or valuation advice.

Which counties do you cover?

We build counties on demand rather than pre-loading the country, so the list grows with what customers ask for. Tell us the county you want and we will tell you whether the assessor data and LiDAR coverage support it — and if they do, it is usually ready inside two weeks.

Why don't you cover Texas?

Texas is a non-disclosure state: sale prices are not public record. Any land valuation for a Texas county is built on data that mostly does not exist, and we would rather say that plainly than sell you a model trained on nothing.

What does a record cost, and what counts as one?

A record is one parcel exported with its owner mailing data. Browsing, filtering and reading the report inside your subscription is unmetered — you only pay per record when you pull a list out to mail.

How fresh is the data?

Parcel and owner data is refreshed quarterly from the county assessor, along with new comparable sales. Terrain is derived from USGS LiDAR, which is re-flown on a multi-year cycle; flood and wetland designations are read live from FEMA and the National Wetlands Inventory at each refresh.

Tell us the county. We'll tell you if the data holds up.

No demo call required. Send a county and we will come back with a sample of what the report looks like there — or an honest note about why it doesn't work.
