I am new in BP, and I am looking to understand where I start with learning about REI.I currently live in New York which it's not a good place to start investing.i know the difference between STR,MTR,LTR....

Considering that, you are likely going to see appreciation year over year, which essentially will be additional equity you'd capture just by simply living in the home. 

@Hudson Filippi What part of Northern MN do you live in now?

Does USAA know that you are living in it?

Your primary residence - if you've lived in it for 2 out of the 5 years prior to selling you'll get the $250K/$500K tax free iike @Clint Galliano said. 

I am an out of state Investor and I know a lot of you live and invest in St.

I also have registered my "rental company" with the state of Maryland, where we live. 

If you are willing to live in urban areas you may want to talk to a local bank in your market and see if they have any incentives or grant loans for certain areas.  

If you plan to buy in your hometown, buy a 2-4 unit, and live in one of the units.

Also, if it fits your budget and your business needs a write off BPCON lives up to the hype.
