Questions to ask before you buy

Questions worth investigating for any waterfront property. They are not claims that this property has a problem or meets any condition.

  1. Who owns the shoreline and the land under the water, and are there easements or public-access rights along it?Ownership can stop at a high-water line, a survey line or a seawall. A title search and survey answer this, not the listing.
  2. Is a dock, slip, lift or mooring included, and do the rights transfer to you?Docks can be shared, leased, assigned by an association or held under a permit that does not automatically transfer.
  3. What permits exist for the dock, seawall or other shoreline structures, and what would new work require?Shoreline work is often regulated by local, state and federal agencies.
  4. How much does the water level change by season, by tide or by reservoir management?Depth at a dock in one season can differ a lot in another.
  5. What does flood insurance cost for this property, and what does the current flood map show?Get a quote from an insurer or agent. A flood zone is not a premium, and no zone does not mean no risk.
  6. What maintenance does the shoreline need (seawall, bulkhead, riprap, erosion), and what has been done recently?Shoreline structures are expensive to repair; ask for records and inspection reports.
  7. How are water, sewer or septic, and power provided?Waterfront septic systems and wells can have extra rules and inspections.
  8. How do you reach the property by road year-round, and who maintains that road?Some waterfront roads are private, seasonal or shared.
  9. What local rules apply: rentals, docks, boat lifts, fences, tree removal, setbacks?Rules come from the town, county, state, lake authority or association and vary widely.
