Guidance/Advice Wanted for a motivated newbie!

[Brenda Casillas]

Hello BP community!  Newbie here :) I am looking into purchasing my first multi-unit (2 units) property where I will live in one and rent the other.  I am trying to prepare for the future as much as possible and wondering if in 2-3 years if I decide to purchase my own SF home, how does financing/lending work? Any books/blogs/ recommendations and advice is welcome!
