I knew a college age guy 30 years ago who did this, before it was 'house hacking'.

Don't forget about the previous owners right of redemption!

My current RE agent is JB Farrell of Keller Williams Realty, he's lived in the area for longer than I've been alive.. and I was recommended to him by an agent who offered to help me from one of my previous posts!

I was thinking of anything really like storage and could build something back there, rent for parties, I’m really up for any ideas.

Unless that LLC isn't doing anything for you right now...I normally recommend (again, not an attorney but based on my previous experiences) that you create LLCs in the states where you're holding the properties. 

Worst case scenario the previous owner used to own both properties before the one further back was seized, so I'm pretty confident under existing precedent that the courts would grant me easement under unity of title and necessity.  

To add on to previous posts, if you would like just a broad overview of the business and to look at a little more detailed introduction (Probably similar to the things you will learn at a seminar that costs) you can use youtube.

Hi,I am leasing out a college house to some engineering students and they want to pay the full year rent up front.

I would also call previous landlords and their place of employment to ensure they work there.

I bought a lot of foreclosed property after the collapse and my guess is that in every one of them the investors in the previous syndication had a 100% loss.
