DictionaryThe buying process

Manufactured home: what it means

A manufactured home is a home built in a factory and moved in one or more sections, on its own chassis, to the site. Federal law defines it this way, with or without a permanent foundation, including its plumbing, heating, air-conditioning and electrical systems.

In Spanish it is

Casa prefabricada (manufactured home)

Also written as: mobile home · trailer · HUD Code home

The full explanation

Many people call it a mobile home or trailer. For Fannie Mae, it must meet HUD's federal standards; modular homes and what it calls prefabricated or panelized homes do not count as manufactured homes. It can be titled as real estate, generally when it sits on a permanent foundation on land the owner also owns, or as personal property, which is usually financed with a chattel loan.

An example

Martín and Laura buy a manufactured home and set it on a permanent foundation on their own land. That way they can title it as real estate and apply for a mortgage instead of a chattel loan.

You will see it in…

  • The home's title, as real estate or personal property
  • The HUD data plate or labels on the home
  • Financing offers where the homes are sold

Still confused by a paper?

A HUD-approved housing counselor can walk you through it. Agencies usually charge little or nothing, many work in Spanish, and they do not sell you anything.
