What this skill does

# Land Assessment & Rural Property

Buying land is the biggest financial decision most people will ever make, and rural land has traps that suburban homebuyers never encounter. No municipal water means you need a well ($5,000-15,000). No sewer means septic ($10,000-25,000). No road means you might be landlocked. This skill is for people thinking about buying land — homesteading, building, farming, or just getting out of the city. It covers what to check before you sign anything: water, soil, access, zoning, utilities, flood risk, neighbors, and the full financial picture including the improvement costs that nobody mentions until you've already closed.

# Localization note — land purchase processes and regulations vary enormously by country.
# Agent must follow these rules when working with non-US users:
- Water rights systems are jurisdiction-specific:
  US Western states: Prior appropriation doctrine (water rights separate from land)
  US Eastern states: Riparian rights (tied to land ownership)
  UK: Abstraction licences from Environment Agency
  Australia: State-based water allocation systems
  Canada: Provincial water licensing
- Soil survey equivalents:
  US: USDA Web Soil Survey (websoilsurvey.nrcs.usda.gov)
  UK: Cranfield Soil and Agrifood Institute (LandIS)
  Australia: ASRIS (Australian Soil Resource Information System)
  Canada: Canadian Soil Information Service (CanSIS)
- Flood mapping:
  US: FEMA flood maps (msc.fema.gov)
  UK: Environment Agency flood maps (flood-map-for-planning.service.gov.uk)
  Australia: State-based flood mapping services
  EU: European Flood Awareness System
- Zoning and planning permission systems differ fundamentally:
  US: County zoning ordinances
  UK: Local planning authority permission system
  Australia: State and local government planning schemes
- Septic/wastewater requirements are locally regulated everywhere.
  Agent should direct user to local environmental health department.
- Title search and conveyancing processes vary by country.
  Always recommend a local real estate attorney or conveyancer.

## When to Use

- User is thinking about buying rural or semi-rural land
- Someone wants to homestead and needs to evaluate property
- User found a property listing and wants to know what to check
- Someone inherited land and wants to assess its potential
- User wants to understand true costs of developing raw land
- Someone is comparing multiple properties and needs a framework

## Instructions

### Step 1: Water assessment

**Agent action**: Water is the single most important factor. Walk the user through every water question before anything else.

```
WATER ASSESSMENT — CHECK ALL OF THESE:

Well potential:
[ ] Check county well logs (often public record at county health
    department or state geological survey)
[ ] Talk to neighbors — what depth are their wells?
    Depth determines drilling cost ($15-50 per foot)
[ ] Typical well drilling cost: $5,000-15,000
    (shallow wells 50-100 ft are cheaper; 300+ ft wells are expensive)
[ ] Well flow rate matters — 5 gallons per minute (GPM) is adequate
    for a household; 1-3 GPM is marginal; below 1 GPM is a problem
[ ] Water quality testing: $100-300 for a comprehensive panel
    (bacteria, minerals, heavy metals, nitrates)

Water rights (CRITICAL in western US states):
[ ] In western states, water rights are SEPARATE from land ownership
[ ] Prior appropriation doctrine: "first in time, first in right"
[ ] Buying land does NOT guarantee you can use the water on it
[ ] Check with state water resources department before purchasing
[ ] Verify what water rights convey with the sale

Surface water:
[ ] Creek or spring on property? Year-round or seasonal?
[ ] Springs can be developed for household use (testing required)
[ ] Seasonal creeks dry up when you need water most
[ ] Pond potential — useful for livestock, irrigation, fire suppression

Municipal water:
[ ] Is municipal water available? How far to the main?
[ ] Connection fees: $1,000-10,000+ depending on distance and utility
[ ] Monthly cost for rural water districts

BOTTOM LINE: No reliable water source = don't buy the land.
Everything else can be fixed. Water can't.
```

### Step 2: Soil and septic assessment

**Agent action**: Direct the user to the USDA Web Soil Survey and explain what the results mean. Cover the septic percolation test.

```
SOIL ASSESSMENT:

Before you visit the property:
[ ] Go to websoilsurvey.nrcs.usda.gov
[ ] Enter the property address or draw the boundaries on the map
[ ] The report tells you:
    -> Soil type and composition
    -> Drainage characteristics
    -> Building suitability (load-bearing capacity)
    -> Agricultural productivity rating
    -> Septic suitability
    -> Flooding frequency
    This is free and available for nearly every parcel in the US.

On-site soil testing:
[ ] Get a soil test through county extension office ($15-30)
[ ] Tests for: pH, organic matter, nutrients, contaminants
[ ] Tells you: what will grow, what amendments are needed,
    whether soil is suitable for food production

SEPTIC PERCOLATION TEST (required before building):

If there's no municipal sewer, you need a septic system.
If the soil won't percolate, you CAN'T install a septic system.
If you can't install septic, the land may be UNBUILDABLE.

[ ] Hire a licensed soil evaluator or contact county health department
[ ] They dig test pits and measure how fast water drains
[ ] Perc test cost: $500-1,500
[ ] Failed perc test options:
    -> Engineered septic system (mound system): $20,000-40,000
    -> Composting toilet + greywater system (where legal)
    -> Walk away from the property

Septic system cost (if soil passes):
- Conventional system: $10,000-20,000
- Mound or alternative system: $20,000-40,000
- Maintenance: pump every 3-5 years ($300-500)

GET THE PERC TEST DONE BEFORE YOU BUY.
Make your purchase offer contingent on passing the perc test.
```

### Step 3: Access and legal road rights

**Agent action**: Check road access. This is where many rural land deals fall apart.

```
ACCESS ASSESSMENT:

Physical access:
[ ] Can you drive to the property year-round?
[ ] Is the road maintained? By whom? (County, private road
    association, or nobody?)
[ ] Winter access — plowed? Passable in mud season?
[ ] Distance from paved road to property boundary
[ ] Condition and grade of the road (a sedan or a 4WD requirement?)

Legal access (this is where it gets dangerous):
[ ] DEEDED EASEMENT — best case. A legal, recorded right to cross
    someone else's property to reach yours. Recorded at the county.
    Permanent and transfers with the land.
[ ] PRESCRIPTIVE EASEMENT — you've been using it, but it's not
    recorded. Legally defensible in some states but risky. Can be
    challenged.
[ ] VERBAL AGREEMENT — worthless. Neighbor says "sure, drive
    through." Neighbor dies, new owner says no. You're landlocked.
[ ] NO ACCESS — the property has no legal road access. This is
    more common than you'd think. It makes the land nearly worthless
    for building and extremely difficult to resell.

[ ] VERIFY: Get a title search that specifically confirms legal a
