Scrapping an old mobile home is not gonna get you all that much money and most people pay companies or people to remove mobile homes from their property.
Theirs not much scrap money in a mobile home even when the mobile home contains some copper wire, copper pipes and aluminum siding or tin roofing.
The mobile home frame would bring around $50.00 to $100.00 and the aluminum siding if it has it would bring maybe $50.00 to $100.00 at today's scrap metal prices.
And then the copper wire might bring around $40.00 to $100.00 depending on if it has copper wire and plumbing or brass fittings.
But if it has aluminum wiring as some older mobile homes did have then it would be even worth less.
So you're looking at maybe $200.00 to $300.00 in scrap metal at most when scrapping the mobile home and it's a lot of work to tear down a mobile home.
