>>Set the items out in Chicago, Detroit, etc. Problem solved.<<
Seriously that is what I do in my MILs house in Mexico. I replaced a bunch of stuff like a blender and some TVs and just put the old ones (blender was rusty, the TVs were old tube types) out in front by the roadside.
Gone within an hour.
Your MIL’s neighbors must cruise the streets here in the SF Bay Area, too. Things are gone quickly. If you want things to disappear slowly, put a “FREE” sign on them. If you want them gone right now, put a “FOR SALE $100” sign on them.
“old tube types”
Some tubes are worth a couple of bucks if still working.
“Gone within an hour.”
We remodeled my wifes office. We replaced two of those old style standing stainless steel water fountains.
I dollied one outside and went back in for the other but had
several phone calls to make. Maybe 15-20 minutes later somone had stopped and started lifting it up into their truck. I yelled out we had another and he came and got it too.
Both were gone in a half hour.
This was about 10 years ago when steel and metal was sky high. I was told the stainless water fountains would have brought major bucks.
