I have heard that some HOA's limit the amount of units that can be rented in a particular complex.

So that is something you always want to consider- what market will best fit your goals, rather than just hearing a particular market is amazing and going for it.

I've been to this particular boot camp several times and while I stopped take copious notes, there were times where I might listen to information I knew for say an hour, and of the 60 minutes, there was inevitable those 2 minutes with some tweak that I was able to walk away with, that made a huge change in my business.  

This particular home I know I'm going  to run into some kind of problem because the basement is mostly finished, but even I know it's not to code just from what I can SEE (let alone vapor barriers and whatever). 

That is designed to mitigate/limit their risk and is particularly true of the large/high volume originators who are going to package and sell the loans they originate. 

I am particularly interested in those working with Investors chasing wholesale prices, making low end offers, properties anywhere between $50,000- to $250,000- so the low end properties. 

Do you have a particular area of Charlotte you are focusing on?

Anything additional that AirBNB brings in - consider it gravy, but do NOT rely on it as the default income source, particularly in your first year.Unless you have a  track record of successfully hitting vacation rental projections over the fence consistently - I would not recommend running your numbers assuming that you'll book out every single day in a month with the exception of 7 days vacancy.

I would encourage you to slow down and focus on particular areas and define the types of properties you are interested in.
