Instead, with bull-headed stubbornness, I decided to give real estate one more push.

They can also purchase a humidifier, open the windows, or take other steps to prevent growth.The mold will cause staining, if it hasn't already.

for this reason I will never directly work with any wholesaler save a very very few... that personally know well.its a stain on our profession these unlicensed people playing investor.. :)  

What is the best way to cover up or remove the stains?

I've had to paint one bathroom with water stains on it and my tenant has never asked me for anything since.

When I used to sell way back in the day when i wasn't yet an agent, despite the 'Principals Only' warning boldly plastered all over my FSBO listings, agents nevertheless lined up at my doors with the usual pitch even when notified in writing to cease communication, still wanting ERTS, throwing fits and all, sometimes even disrupting my open houses under the guise of bringing 'buyers ready to sign' that were 'on their way'  yet never showed.Granted over those years, there were 1 or 2 out of dozens upon dozens agents who were up for the challenge to compete with my own offers, but most others were just too greedy or whatever and just would reiterate the holdover clause like parrots, pretending to not understand holdover clause is why exclusive agency without right to sell remains a viable compromise and formidable challenge to truly measure up to.have you as investors (and/or as agents) ever had similar gripes with stubborn/aggressive agents who yet weren't up for the challenge competing with the owner(s) themselves to find the best offer that successfully closes?

One trick I have used to get the scuffs out is a color match stain stick. 

DESCRIPTION Replace locks on all exterior doors 150 Replace 14 interior door knobs 308 Prep all walls and ceilings for paint which includes muddying all small holes dents and priming stains 200 All interior trim is stain grade which requires all to be sanded, oil primed, and two coats of finished white paint.

I would love to hear step 2 for the extremely stubborn tenant.

I've also had a couple of nightmare tenants that stained the rugs in a one year lease, that required me to replace after one year.
