I see WY is up there and seems to be the most "incorporation friendly" state.

Consider the possibilities and incorporate them into your business plan.

Or to resort to other tactics like posting signs, calling FSBOs, networking, physically looking for abandoned properties, etc.?

Physically inspect the property on the day of the auction and knock on the door of the subject property.

I am physically stuck to a location while a business can often move locations or expand. 30% plus returns investing into a company is very very doable.

I would also incorporate a profressional picture of you.There is a local real estate broker who I think has done a great job with his marketing.

I am a recent grad and have started working in corporate America, but I ultimately want the freedom that real estate investments have the possibility to provide.

There are national title companies like Attorney's Title or Stewart Title which cover multiple states.The location where the buyer or seller physically sits down and signs the closing documents does not matter.

:-)   What are your systems like and how do you physically store and keep track of your keys?  

One of the things I know I will have to figure out, since I'll be doing most of the physical work myself, is getting the right people to do the things I don't know how to do.
