Just Google: Mobile Home Removal. By the time you type the last word, Google should add the State. Then click a link and call them for estimates.
In my area, the typical cost ranges from $1,000 to $2,000 based on weight, width, and length. I've even seen some look up the Serial Plate and get any information off of the Manufactured Housing website to get all the specifics about it beforehand for salvage.
I've indicated in the Forum here before that I've been asked to do appraisals on poor condition Manufactured Homes in a certain development and in conversation I tell the Owner the estimated cost to remove it (about $2,000) and what typical lots are selling for in the development ($2,000); thus negating any true value for the entire property. Not many Clients want an appraisal when they figure out the value will be $0. For that reason, there are abundant vacant trailers in the development which end up being foreclosed on for the non payment of development dues as the owners walk away from them when they need too many repairs. The development seldom even breaks even on the foreclosure, so they sit rotting for long periods.
