Why Due Diligence Matters for Farm Buyers in Washington

Buying a farm or rural property in Washington State is a significant investment—one that requires careful research and verification before you commit. Unlike residential homes, agricultural properties come with unique considerations: land use rules, water rights, soil quality, access, and environmental constraints can all impact your plans. Here’s a practical, step-by-step checklist to help you navigate the due diligence process and avoid costly surprises.

A Farm Buyer's Due Diligence Checklist

Washington Farm Buyer’s Due Diligence Checklist

  1. Conduct a Thorough Property Inspection
    • Visit the property in person and inspect both indoor and outdoor areas.
    • Check for air quality, drinking water sources, surface and groundwater quality, soil conditions, and proximity to hazardous sites. (Washington Department of Ecology)
  2. Verify Legal Ownership and Title
    • Order a title report from a reputable title company.
    • Review the title commitment for recorded liens, ownership claims, restrictions, and easements. Read carefully and ask questions if anything is unclear. (Vertex Legal)
  3. Confirm Zoning and Land Use
    • Contact the county or city planning department with the parcel number and your intended use.
    • Confirm zoning designation, allowed uses, minimum lot size, setbacks, and any overlay districts. Don’t rely solely on the listing description. (Vertex Legal)
  4. Check Parcel Data and Boundaries
    • Use county assessor and GIS websites to review parcel number, boundaries, assessed value, tax information, and mapped features.
    • Remember: these tools are helpful, but not a substitute for a legal survey. (Vertex Legal)
  5. Verify Access
    • Do not assume that a visible road or driveway means you have legal access.
    • Confirm public road frontage or a recorded, enforceable access easement. (Vertex Legal)
  6. Assess Water and Septic Systems
    • For properties outside municipal water/sewer service, check well and septic system status.
    • Contact the local health department for septic feasibility, requirements, and permit history. (Vertex Legal)
  7. Review Environmental and Conservation Factors
    • Ask about wetlands, floodplains, critical areas, or conservation easements that may affect use or development.
    • For properties with agricultural conservation easements, review program requirements. (USDA NRCS Washington)
  8. Calculate Total Costs
    • Include purchase price, closing costs, taxes, insurance, and any required improvements or compliance costs.
    • Factor in ongoing operational expenses and potential upgrades.
