Property research platform
Plot Eval turns property lists — tax sale CSVs, county exports, foreclosure or assignment lists, or your own spreadsheets — into a single research workspace. You upload a CSV; we match rows to properties, geocode and enrich them with county and state GIS data where the dataset's county tier supports it, score them with a prioritization-style letter grade (not a recommendation), and put everything on a map. Each property gets a dedicated page with maps (street, satellite, street view), a research checklist, timestamped notes, decision status, and reminders for follow-ups and deadlines. The Dashboard shows the next reminders due across your datasets; open Agenda or Calendar for a time-based view, and Decisions to review how you've marked properties workspace-wide. Team workspaces can also use Inbox for assignments and activity.
Investors, researchers, and analysts who evaluate properties from tax sales, county data, or bulk lists. If you spend time jumping between county GIS portals, parcel maps, and spreadsheets, Plot Eval centralizes the workflow: one place to import, enrich, map, grade, and research each property—with notes, reminders, and status so nothing falls through the cracks.
Free Explorer is a limited way to try the real workflow: 1 active dataset, up to 100 properties, 3 active reminders, notes, checklist, decisions, basic map access, and 30 days from your first property upload or add. It does not include exports, team features, parcel polygons, advanced overlays, or advanced GIS. Individual and Team plans unlock full operational use, including exports and deeper GIS in supported counties; Team adds collaboration features such as invites and assignments.
The public list includes only jurisdictions where we advertise parcel resolution with or GIS enrichment — not upload-only or unlisted areas. That keeps expectations aligned with what you can select when you create a dataset.
Today that filtered index surfaces 779 counties with parcel enrichment (1 full GIS, 778 limited GIS), grouped by state on the counties page.
Examples of deeper coverage (still subject to tier and data availability):
Maps and geocoding use third-party providers (e.g. Mapbox, Google) under their respective terms. Attribution and data sources are noted in the app and in the footer.
Map results, parcel details, GIS layers, and grades depend on your county and data quality. Check Supported counties before you upload.
Map your property list
See records on a map and open each property with the details you need for research.
Keep leads organized
Use notes, status, reminders, and decisions so every property has a clear next step.
Know what data is available
Check supported counties before you upload so you know where parcel and GIS data may be available.
Properties receive a data readiness score (how complete the record is), a prioritization-oriented letter grade (A+ through F based on tax-to-value, zoning, flood, lot size, owner-occupied, etc.), and a research progress score (your checklist, notes, and status). The letter grade is only shown once data readiness is sufficient. All scoring is automated from the data we have; you can see the full breakdown per property. We do not provide legal, tax, or investment advice — grades are tools to prioritize research, not recommendations.
Site evaluation (location, access, buildability where applicable, neighborhood, liquidity, risk) uses county and state GIS when your dataset's county tier supports it, optional radius summaries, and neutral defaults when fields are missing—so scores can appear even when parcel coverage is partial. Combined grades scale how much site evaluation contributes when data readiness is below 100%. You can pin values from your CSV or county record with manual county corrections on each property when automation misses fields.
Your account and dataset data (including uploaded CSVs and research) are stored in a secure environment. We do not sell or share your data with third parties for marketing. Data is used only to operate the service (geocoding, GIS enrichment, storage, display). See the Privacy page for more detail.
