Investing in 4-plex vs 5+-plex properties?

[Kevin OBrien]

As I've started looking into multi-family properties, Ive come across a number of people who are trying to promote their approach to investing. One of these has been that there are some who are big fans of 1-4 unit properties, and some are fans of 5+ unit properties. Some of the investors I've come across have even gone astronomically higher than 5 units and heavily pushing commercial instead of residential. I've also read varying opinions on residential vs commercial loan options and issues with both.

 My question to the BP members is, what made you choose the property size you did to start with? Were there specific reasons or was it what was available?
