# Land Deal Screener

Screen a land deal in one call: the parcel record and price history against flood, wetland, protected-area, habitat, slope, soil, access and utility red flags.

## Requirements

- The Isopleth MCP server connected at `https://api.isopleth.dev/mcp` with an API key in the `Authorization: Bearer` header (see https://isopleth.dev/docs/mcp).
- Tools used: `parcel_enrich`, `start_run`, `get_run`.
- Cost: 6 lookups per parcel (5 for the parcel, 1 for the 16 point fields).

## Steps

1. Call parcel_enrich with the parcel and the fields listed below.
2. Price check: compute asking price per acre (gisacre, or deeded_acres where published) and compare it with assessed land value per acre and the last sale price and date. Assessed values often lag the market; say so rather than calling it a bargain or overpriced on that alone.
3. Red flags: flood zone A or V or inside the floodplain polygon; wetlands on the parcel (and their acreage); protected area or critical habitat; average slope over about 15 degrees; hydrologic group D soils or a restrictive layer shallower than 100 cm; no road within 100 m; outside water or sewer service.
4. Give each check pass, watch or fail with the value and source, then an overall verdict: clean, needs diligence, or walk away.
5. For several deals, call start_run with kind "enrich" and rank the results by the number of fails.

## Arguments (example `parcel_enrich` call)

```json
{
  "apn": "0123456789",
  "state": "NC",
  "fields": [
    "nfhl_flood_zone",
    "within_floodplain_polygon",
    "intersects_wetland",
    "wetland_acres",
    "intersects_protected_area",
    "intersects_critical_habitat",
    "slope_degrees",
    "elevation",
    "soil_hydrologic_group",
    "soil_restrictive_layer_depth_cm",
    "nearest_major_road_distance_m",
    "nearest_road_distance_m",
    "within_water_service_area",
    "within_sewer_service_area",
    "nearest_transmission_line_distance_m",
    "lcms_class"
  ]
}
```

## Output

A screening table (check, value, pass/watch/fail, source), the price-per-acre comparison, and a one-paragraph verdict. This is a desktop screen, not a survey, title search or wetland delineation.

Every value carries its source, license and attribution. Keep the source next to each value, and show the attributions if you share the results.
