Landlord shit. Cue anxiety and/or panic attack

In my region, nobody calls “trailers” “manufactured homes”. They are strictly referred to as either mobile homes or trailers. “Manufactured home” means something else entirely - a much larger one- or two-story home with a steeper pitched roof that could easily pass as a stick-built home. I was pointing out that terminology in one region might not transfer to other regions. Your area apparently calls them manufactured.

In my area, very few 40 year old mobile homes are worth much money, and perhaps not enough to pay to move it. A lot of older mobile homes are simply abandoned where they sit - forfeited to the land owner - rather than moved. The OP should call a couple of trailer movers to a) get an estimate on moving cost: and b) find out if they know of anyone who is looking for a home to buy.

There is no way that any of us know exactly what the preferred course of action might be, but the OP should be able to figure it out with a little homework.

As for the rental insurance issue, many landlords require it for the liability protection it provides. If someone gets hurt, the tenant’s insurance is used first before the landlord has to get involved.

Or if the state’s landlord-tenant laws say so. Landlords eventually get the right to remove abandoned property, and sometimes this allows them to do whatever they want with the property.

The good news is that while he’s still accepting her rent, he cannot claim that it’s been abandoned.
