Mobile home rules of thumb?

[John Humphries]

Are there any quick and dirty tips to evaluate mobile home deals in which the mobile in question sits on a park? It's a $5k trailer with $400 lot rent. To me, that seems like putting 5k down on a SFH and paying a $400/mo mortgage. It should rent for somewhere in the 800-1000 range after rehab. To help estimate expenses and project a return, should I use the same formula I use on a stick built sfh or are there different rules of thumb with mobiles?
