It might actually be better, you just need to weigh out the pros and cons. Keep in mind that it is considered personal property and not real estate. You also generally have to pay a much higher rate to finance them and for a shorter term than a mortgage. As for renting a room, you would just need to know the rules of the park it exists in. Usually you can't sublease, but most of the time you can in fact rent out a room if you are also occupying it. They are governed by HCD, the department of housing and development so you have some resources available for disputes etc. I just purchase one for my son who recently moved back to California from Las Vegas. The park is under new management and they have raised the rent significantly, but I was able to negotiate a better price because of it and for the square footage per dollar it was worth it over renting. Eventually he will get a house, but for now it's a great option and he will be renting out a room to offset the costs.
