Getting into a property for little money down

[Nick Snider]

I'm currently house hacking a duplex that I purchased in November of last year a couple months ago. I'm currently saving for another property but not wanting to have to put down 20% on a property if I don't have to. I know there's a bunch of ways to do seller finance, subject to etc. but looking for more specifics as far as in depth on how to word contracts and effective ways to target those types of potential sellers. Any help would be awesome, thanks!
