Even if the data comes out clean, you can still learn so much about them. 

I moved on to purchase rentals that are clean BRRRRs and built a rental portfolio of over 7 figures.

We also updated flooring so we took out interest free loans to complete those projects.

We seldom paint, we seldom replace flooring.  

We found a painter that saved us so much on about 7 years of turnovers, and an excellent flooring guy, but they've now both retired.

We rent single family homes above median rents, fully remodeled and we don't use carpet on the main floor at all. 

Maybe a finding property that's move in ready or needs some light renovation work (paint, flooring).  

I’m currently trying to decide between two 3 bedroom units (one is roof top with gulf views and boat slip, other is ground floor with direct access to pool and big patio) , or a one bedroom in the same building that’s also roof top with gulf views (I believe sandpiper).

Remove acoustic, paint walls light tans, use composite wood floors.  

I think a ReafCo filter would clean up half of the issues.
