History of mobile home
This form of housing goes back to the early years of cars and motorized highway travel. It was derived from the travel trailer, a small unit with wheels attached permanently, often used for camping. Larger units intended to be used as dwellings for several months or more in one location came to be known as house trailers. Many people who could not afford a traditional site-built home or did not desire to commit to spending a large sum of money on housing began to see factory-built homes as a viable alternative for long-term housing needs. The units were often marketed as an alternative to apartment rental. However, the tendency of the units of this era to depreciate rapidly in resale value made using them as collateral for loans much riskier than traditional home loans.
