It may prevent them from qualifying for another rental, a home loan, car loan, credit card, etc.

On a lot there is a  front house that is a 2 family home , and then in the back is a 3 car garage that has a 2br 1ba unit above it..

It will cover you in your cars, your personal home, and your rentals. 

Yeah go to the closest gas station and sit there for 10 min, who is going in and out are more people walking in than cars, the location of an investment is the one thing that you can't change.

I am willing to learn as much as possible so please suggest materials and conferencesThank you Just a word of advice, if you ask for advice to be honest most people are gonna try to sell you on their market and ultimately their service or course, you need to figure generally the direction you want to go, your risk tolerance, the area, the trade offs between appreciation and cash flow, understand, it’s going to be hard to get much if any cash flow in this market, brrring & flipping are close to dead with the exception of a few areas in dc and a few rural markets, even there it’s difficult, come up With a basic plan than go into a conversation with whoever you work with and at least understand the right questions to ask, the best comparison I can make is my mom always makes me go to the mechanic with her, even though I can’t actually fix the car, I can at least talk the same language as the mechanic.
