Put 20% or 25% down on multiple 4 plex's or larger % on 1?

[Robert Falco]

Myself and a couple family members are looking to get into multi family rentals. We have experience with single family homes. We are leaning toward 4 plex's. I would rather put 20-25% down on a couple but other family members are thinking about just putting 60-80% down on one. What are some other thoughts and arguments to sway toward more leverage?
