That's crazy! Somebody will make a killing on that mobile home when she passes! Even if no one lives in it after it's hauled away (I doubt this, honestly. Country slum lords, ahem, landlords to low income rural people, will snap up any mobile home that's still liveable and put them out in places where there's no zoning) do you know how much the recyclers will give for all the metal pieces parts in a mobile home?
OTOH, I've noticed that unless you're dealing with a local S&L or a land bank or Green Tree or similar, a lot of people in banking and realty don't have any clue about the economics of rural existence. For example, we left a mini-tractor at a home once as a gift to the new occupants. They didn't want it and wanted us to pay $1K to get rid of it. Our realtor and bank were in total agreement with this. I went on Ebay and sold the tractor as a bargain for 1K to a main 2 states away within 20 minutes for pickup the next day!
