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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- How are water, sewer or septic, and power provided?Waterfront septic systems and wells can have extra rules and inspections.
- How do you reach the property by road year-round, and who maintains that road?Some waterfront roads are private, seasonal or shared.
- 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.
