Buying First Multi-Family Home

[Dexter Stewart]

Hi there BP, 

I am looking to get into the REI world by building a portfolio of rental properties. I have done quite a bit of homework on this topic and it seems to me the best way to get started is with a multi-family home.

My question(s) are as follow:

1. How does one fine these homes? 

2. Do I necessarily need to live in the property? 

3. I see many blogs talk about 30-year mortgages, but wouldn't it be better to get a 20-year or 15-year mortgage in order to pay it off faster (more positive cash-flow)? 

Thanks for the time BP.
