(I had mentioned to them that it was likely a worn out rubber boot on the plumbing vent or the vent for the bathroom exhaust fan because these were the only penetrations on the roof.)

The main things you want to look for or avoid in the area, in my opinion, is going to be Flood Zones, moisture issues in the crawl space (it's very humid), and maybe knob and tube wiring if it was built before the 1940s. 

The description says that the basement has areas which need mortar repairs, a leak in the chimney, and signs of moisture in the first floor bedroom, but you've allocated $0 for an initial repair investment. 

I had on a similar issue noted on one of my properties as a seller as there has been some moisture in a crawl in space and we gave a credit.

I'm waiting for it to get a little warmer to be able to open up and dry out the entire south wall - it's not going to be a fun fix@Bjorn Ahlblad Yeah, I was thinking of giving him a couple months notice and even tell him that the repairs will be from the inside too and that he will have to move out (given how much water was penetrated over the 4 years, it could be some inside repairs too)

@Andrew SchraderRing Alarm Flood and Freeze Sensor https://www.amazon.com/dp/B07M943G7L/ref=cm_sw_r_sms_apa_i_ex3lEbD8K376BNotifies you of moisture or temperature drops.

You may want a slightly higher sheen (velvet) in the kitchen and bathroom where you may have more moisture and cleaning. 

At best they prevent an infected person from spewing the virus out when they cough/sneeze etc..... but the virus can penetrate the mask the other way pretty easy....

Mold is caused by moisture and lack of ventilation so yeah thats the deal killer for me personally.

I just received a copy of the previous inspector's report, and there were some plumbing/electrical issues (that supposedly have since been fixed), high moisture in some areas (so we will need to do a mold test), and a roofing issue on the carport, as well as some wood rot and a few other issues.
