@Evan Parker, This is a question that is bigger than “ask the REI folks”, and I think your gentrification example has more to do with capitalism and society as a whole, of which landlords/developers/etc are just cogs in the machine. 

They've got a split allegiance between you and the Brokerage Owner and guess who wins most of the time.Good luck buddy and keep that Buying machine going!

You also need someone you can trust to collect the cash and stock the change machine on a stand alone car wash.

It is a profitable business based on being personable, flexible, and essentially by not being a machine. 

Im using deal machine for driving for dollars.

Im looking into putting a coin washer and dryer machine in there.

Cheaper machines and I cannot imagine going into a unit to empty coins...

I'm experienced in Machine Learning, so I think it could be interesting to partner with an investor to build a competitive-advantage home price model

I’m pretty sure they’re literally putting the sheet in a machine. it’s ridiculous 

Check out ozone machines, which can also address smells and bedbugs.
