Out of state buy and hold

[Ronald Warren]

First I'm a newb looking to make my first purchase (or 3 if things work out right). Have been reading and listening to BP for a while and it's time to jump in. I make a really good living with my current job but I want to build a real future for my family. I'm in TX but have a few properties that have been put in front of me in Oklahoma that look to be good deals. I am in the area fairly regularly and have family there also who can help with minor issues that arise which helps. My question is are there tax or legal issues which come with owning out of state properties that I should be aware of?
