The residence is a "product," in your understanding of the thing, and tossing these people out of the place they call home is "naturally" a good idea.Can you and @Austin Fruechting just maybe try for half a second to imagine that a man who was born in a stable, lived in a tiny village for most of his life learning a simple trade, wandered jobless all over the land with his followers living on the charity of others, and died penniless on a cross to be buried at the expense of a friend perhaps, just perhaps, did not particularly care about crushing it in multifamilies?

Definitely refer to them as "tiny" houses instead of "little" houses, will be more hip and command higher rents

For now, the hearth will make a good place to put the TV in an otherwise tiny living room.

Properties are assets, they hold a quantifiable value and use, MONEY is not such a thing, it's value is based on the quantity of such int he system and therefore more of it created makes all in the system worth less BUT since a dollar bill can't change it's ink to read "sorry, now $0.97 bill... oh wait, $0.89 bill now" what happens is the assets of value GO UP.

These properties will appeal to certain renters but it's going to be a tiny minority and you'll have plenty of competition for that limited demand.

However, they installed what I swear was a little tiny kids toilet in my bathroom at first when I ordered an ADA adult sized one, they forgot a recessed 'picture alcove' that was supposed to be in the master bath when framing/drywall, and other small details like that. 

That means taking down two walls around the tiny kitchen to open it up to the dining room and living room, tile the floor, put in an island, and redo the bathroom completely (tile for floor and walls).

Since you are new and an unknown quantity, they will want to err on the side of caution.

There is a reason why some investors scale rapidly while others seem to spend inordinate amouts of time and energy for a tiny fraction of the deal flow in their market.  

Can make more $$ with quality clients then quantity as a wholesaler in our opinion.
