The HUD inspection the next day finds a water stain on the ceiling and fails the property.  

If it is worn or stained, yes, put in new carpet.On the other hand, we have had prospective residents tell us that we need to replace this stove or that carpet, and sometimes they are brand new. 

I stripped all the carpets and they were all stained.

I'm on the fence with a mid grade carpet that gets replaced with each tenant, versus a higher quality that can stand up to stains and cleans well. 

This can be a great departure from the tithe to pay for gyms, lobbyists or stained glass windows.  3.

Use MMR available at home depot. 1 product will kill the mold, but the stain remains, the other will remove the stain (super concentrated bleach w surfactant) so, you will need ventilation as it's strong. 

For example the tenant has been complaining about 2 ceiling tiles that became stained during a rainstorm 2 weeks ago.

and its a fake POF if you read it.. total BS and a stain on the industry.. absolute Fruad.. 

Insurance is getting more and more expensive with renewals doubling or even tripling in some cases.Insurance companies will issue notices to quit if they see stains on your roof from google earth. 

I had 2 suppliers for such, 1 who even did pre-stain and paint.
