How does one get into investing into apartment?

[Fahadbin Alam]

So I want to go big because I feel like I can handle and I see that a lot of investors like brandon turner says if they can go back in time they would just invest into 5+ units.

My questions is how would you start doing so. I have about 20k, may not be a lot, but I can try and have partners. 

1. would you need to get a business loan for these?

2. what would be a good place to start?

3. are there any books on apartments and foreclosures?
