Attorneys will usually recommend having a survey as it is useful to know exactly where the property lines are. A survey will also reveal if there are any encroachments over the boundary lines. A survey of a standard residential lot currently costs $250.00 – $350.00, though large properties or acreage cost significantly more. Oftentimes the charges for a survey can be covered by a seller’s closing cost assistance to buyers. In some instances (such as with an inside unit in a townhome complex) the need for a survey is mitigated.
