Experiences will vary significantly based upon location.

After talking with my mentor (He's a realtor with 20+ years experience) he suggested purchasing a rental property first.

You don't need to know everything to get started; you need a foundation to build on, and the rest will come through experience and then refining your education.You can build a basic understanding of investing in 3-6 months.

Your experience reminds me to manage the portfolio well (i.e. sell losers) and to be patient. 

I have it narrowed down to two agents, one has more general experience in the area and are part of a large organization.  

@Mitch ProvostFrom my experience of working with over 400 investors, your property near Texas A&M in College Station/Bryan has strong investment potential due to the consistent demand for student housing driven by steady enrollment growth.

The fact that you have already owned and sold a rental property gives you a great experience to start from.In terms of the best place to invest - that is whatever place meets your criteria, goals and investing style.Personally flips have not been working as well for me lately, but when we get the right BRRRR deal those are still working well.

If you can get a single family home and have roommates, that's the most approachable strategy and will really allow you to know rather quickly if you hate managing rentals or not.Here's my experience starting at 22, and what I regretted from house hacking: https://www.biggerpockets.com/forums/922/topics/1133476-hous...
