457 Guest House

These structures are detached single family residences designed for one-family occupancy.  These structures are the secondary residence on a lot, and can vary in quality from the main residence.  They are built in many architectural styles or mixtures or styles, and are called by various names depending on the region where the home is constructed, i.e., cape cod, colonial, Tudor, ranch, contemporary, modern or rustic.

Base rank selection on the inspection of both the interior and exterior refinements of the home.  Items such as fenestration (the number and size of window and door openings), roof configuration, materials, workmanship, types of plumbing fixtures, and amount of cabinetry are all indicators of quality.

The following are not included in the costs: Fireplaces, built-in appliances, balconies, porches, swimming pools, and yard improvements.
