I also completley share his advice on a bias for action.If you are interested in a good book reference with checklist like models, check out "The Perfect Investment" by Paul Moore and "The Book on Investing in Real Estate with No and Low Money Down" by Brandon Turner, both also available in audio versions.

I know that the first step is very important because I have already read the book. 

Are you doing your own sets of books?

As @Allen Duan said 1-2 bedroom are the sweet spot for traveling nurses, but that being said we have a 4/2 that's stayed booked consistently.

Does anyone have any good recommendations on books or accounts I can follow or read to learn more? 

It's the one thing that will take your from analysis paralysis to action because it's the only way to put the learning you've done from podcasts and books into real life - by talking with others who have done what you want to do or who are trying to do what you want to do.Get your finances set and talk to a lender so you know what you can afford.Stay local.

I wrote a book about this; it just appeared on Amazon in paperback. 

I would not expect to hit nearly $3,000/mo in gross bookings with a 3/1 in Cornerstone Village.

I have not yet written a book on this topic.

Not a course, but I recommend the book "Crushing it in Apartments and Commercial Real Estate" by Brian H Murray.
