The houses on the street looked dated, the wood on the exterior was rotting on most houses, but from a previous question I posted I didn't think that was a big issue or a reason to stay away for a buy and hold investment.

It seems with Covid much of the commercial financing had dried up.  

Also our floor stain was lighter than we expected so we had to do two coats, which took forever to dry and we ended up having to reschedule a ton of showings.

Is it dry camping?

You really can't keep water out from the inside.If you want a dry basement, keep water away from the outside. 

We then did a cash for keys deal with our tenant in #1 who was a slight hoarder and had a legit HOLE in the bathroom floor with rotting subfloor that we didn’t know about, she needed to go.

Gotta work the math -- and it isn't as cut/dry as some posters above suggest.So that brings up: how much does a property manager take out of your hide?  

Hidden rot, mold, pest, and foundation problems.4. 

I got brand new floors for the whole house done, 1 bath floor retile and some dry wall work.

Its never that cut and dry.
