Ok, so permits are going to be a thing and I'll have to hire someone to fix this mess. 

By law, if you are treating a known source of lead paint (not saying you are, and your report may indicate the opposite) you need to be licensed in lead safe practices or hire someone who is. 

Hi I'm interested in gaining experience cold calling and door knocking and was wondering if anyone is interested in exchange for training? I work full time but I can call in the evening and I'm free on weekends.As it ...

The inspector was hired by and works for the buyer, not you. 

I saw that they were no longer hiring and no cars so I did some research and had the property under contract in less than three days.

Sure you may ultimately hire that rockstar hospitality host to run the place for you, but those folks don't grow on trees or leave their job at a luxe hotel for an investor with a single STR still learning the ropes and trying to figure out how to manage day-day turnovers. 

I have an employee who earns $5,000 to $7,000 every week (his paycheck) canvassing door-to-door and he sells home services i.e. plumbing, heating, roofing, house painting, etc..My company has been hiring door-to-door canvassers for about 20 years and it is the best and most-productive marketing and sales arm reaching out that any business can have.

If they refuse to leave, hire an attorney and start the eviction process as soon as legally allowed.

I would pick the area that you feel most comfortable doing work or that you know the most people that you can easily hire and trust and start BRRRRing.
