Of course you want to trust that they did it right - with anti-bacterial spray before they put up the drywall. 

My apologies gentleman my laptop got infected and its taken me this long to get back on track.

Maybe other units are infected too and need to be addressed. 

Im no expert on your area but at least in the US this isn't that normal. most buildings round my area have everything separate and thats the best way to bill everyone, well they infect would get billed directly in this instance.

I have a friend with the bedside manner of an rhino with an ear infection, who refuses to pay fees.

3 subs and myself got really sick, some bacterial thing comes in with all that muck water!

One thing is that really bad tenants tend to "infect" other tenants. in other words, if you have a tenant that causes all sorts of trouble/drama/damage/police reports/noise, etc. they will usually spread this problem as there are some tenants that tend to behave in whatever way the general atmosphere of the building is.

Oh and we also had bed bugs cause one tenant had them and then infected the whole building...it cost 2K to treat the property. 

I confronted him and asked him why he didn’t remove all that infected drywall inside the closet and he said that his company doesn’t deal with air conditioners and didn’t want to be liable for messing up the ductwork etc.

It was more money than we had in reserveMy pets now sees the vet for slight infections, get premium pet food (I have a fat cat that is on prescription pet food that would not be cheap compared to human food).
