How big is to big? Buying a portfolio.

[Andrew Tegeler]

I am looking at scaleing up from I currently have 2 single families and a duplex. I am not sure what direction to go though, I am look at a 23 scattered property portfolio with a 12.39% cap. This would be a big deal for me, and it's way more money than I thought I would ever spend. Or should I purchase properties at the court house one at a time. I guess I am just looking for advice on portfolios, if they are worth it or not. And any advice on who and how I would get financing for them with very little down payment. 

I was planning on using a line of credit for half the down payment and raise the rest somehow.
