But the portions were tiny.

The quantity and quality of data available.It is more appropriate to describe an appraisal as weak or strong than it is to describe it as good or bad.

These lists only contain a tiny fraction of the renter population anyways, so are pretty much useless. 

They flip in large quantity and typically only to investors (versus flipping/selling to primary home buyers).

Ordering supplies before they're needed, in the right quantities that you can store.

It's not just as easy as moving the tiny home.

I'm amazed at the stains people can produce in a bedroom carpet.Laminate is ruined when any quantity of water touches it.LVP is the ONLY way to go IMHO.

They say that cash flow somehow makes them magically immune to any downturn as if their tenants and their cash flow especially in lower end markets (where cash flow on paper looks the highest) will somehow be unaffected ... rent doesn't go down in a recession, it stops ... not all cash flow is created equal, and quality of cash flow in this case is more important than the quantity. 

I didn't read the other posts, but the 1% rule of thumb exists in 'reasonable quantity' for those who look (a little harder to see/find now compared to 5 years ago) in most of NC except the metro areas of Raleigh, Charlotte, Wilmington, and anomalies like Ashville and other lower population/high demand islands like coastal cities.

My tenant asked me today if I would replace the oven (gas stovetop) because it has a lot of tiny grease stains all over.
