Anthony,You would be surprised by using some old school methods like simply writing a letter like you mentioned. 

Turning on the fan will also help eliminate bathroom odors and odors from harmful bathroom cleaning chemicals.Pro tip: Add cleaning the exhaust fan on your cleaning crew’s checklist during turnover.

I've done various methods and would be happy to connect and knowledge share if you are interested.

House is cleaned out  and ready for work to be done. 

Don’t know much about Memphis as a city itself though, I just know crime was a problem back in the day, is that still the case or is the city getting cleaned up and growing?

One that I'm getting close (hopefully) to the end of, was a flip that was a public nuisance property with two lots on either side full of junk (like 10 dumpsters worth..)There was great opportunity with the house, but we bought the other lots as well and cleaned them up (as no one would ever buy the house with those lots filled with junk). 

Each method has a cost in both time and money.  

My interest are house flipping and the BRRRR method.

Would that method work again?

Few left were broken, never cleaned.
