What is a single-family home? One dwelling on its own parcel, with one kitchen, its own lot and no part of the structure owned in common: the unit that housing data, appraisal practice and mortgage programs are built around.
A single-family home is one dwelling on its own parcel: one kitchen, one set of utilities, its own lot, and no part of the structure owned jointly with anyone else. It is the detached house most people picture, and it is the unit federal housing data, appraisal practice and almost every mortgage program are written around. The line that decides it is ownership and structure rather than the shape of the roof. A home that shares a wall can still be a single-family attached home when the buyer owns the lot beneath it and the walls around it outright, which is how many townhouses are titled.
What follows for a buyer is mostly freedom and mostly cost. There is no association unless the subdivision created one, and in the master-planned parts of the Las Vegas valley most did. The owner controls the exterior and pays for the roof, the stucco, the yard and the air conditioning, none of which a condominium owner pays for directly. Appraisals are written against nearby detached sales, so comparables are plentiful and the value is easier to defend, and conventional, FHA and VA loans are all written for it on their best terms.
Two local details are worth checking on the county record rather than in the listing. The assessor carries a use code, the year built, the lot size and the living area, and those are the figures a lender and a future buyer will look at. And a casita or a converted garage does not turn a single-family home into a duplex: a second unit counts when it is permitted, and whether it may be rented separately is a zoning and association question rather than a listing one.
A worked example
A 1,750 square foot detached house on a 6,000 square foot lot at $429,000, which the assessor records as a single-family residence built in 1998. No shared walls, $58 a month in master-planned association dues, and the owner pays for the roof and the air conditioning. The townhouse of the same size two miles away asks $349,000 and $165 a month in dues.
Questions people ask
Is a townhouse a single-family home?
It can be. Where the buyer owns the lot and the structure of their own unit outright, with nothing held in common ownership, a townhouse is a single-family attached home for lending and appraisal. Where the unit is owned as a condominium, with the land and the exterior held in common, it is not.
Does a single-family home have to be detached?
No. What defines it is one dwelling with one kitchen on its own parcel, not owned in common with anyone. Detached is the usual form and the easiest to appraise, but an attached home with its own lot and its own title counts.
