Brrrr question from beginner.

[Brandon Pickens]

I'm Just curious as to how I should go about a the purchase of my first rental. So, my step dad came to me the other day about purchasing one of his rental properties that he dont want anymore, I think he's doing it just because he knows I want to get into investing rather than something wrong with the property. Anyway, he said he'd sale it for 45k says its worth about 75k. Has two buildings on the lot that are rented out for a total of 1000 a month, he's put a new roof on both and  renovated a little on the inside, its pretty much ready to go and a once in a life time deal for me. I may sound stupid but how would one go about this with the brrrr strategy, ( BTW I just bought the book so I'm learning) using little money. I have about half but if I could do it with minimal money and still come out ahead that would be ideal. Feedback Appreciated.
