Is this something that can be treated with bleach and water solution?

Why are you trying to go around the professionals you hired and get solutions here?

Ask the exterminator would he buy the building in the condition it's in or what does he highly recommend to cure the solution.

I am referring to solutions like Alexa and Google home along with the home control lighting and other controls aling with other home health technology like GrandCare to assist seniors to Age In Place.

The solution?

That’s my solution.

Solving Problem A by shifting it to Problem B isn't a real solution.

There's two solutions to this1.

Set up Zillow alerts for all small multifamily that "sell" (when properties transfer ownership landlords will be more open to talking) Network with small multifamily relators about buildings that are under renovations and will have multiple units coming up that need to be filled (problem) where you can "pre-lease" the unit and pay the landlord the 1st day it's available (solution) Remember the name of the game is "How do I profitably solve problems for the people I want to work with!" 

I have completed my senior project with Mitch Deminski and Solutions For Real Estate.
