Making offers on buy and hold multi family real estate

[Ryan Rea]

Quick question.  I've been analyzing multiple deals daily and wanted to ask the other investors how they make their offers?  I've been using the bigger pockets rental calculator because I'm interested in buy and hold real estate for cash flow, and my goal is to get at least $200.00 per door and a 12% cash on cash return.  Once I get to the max amount that I can offer to still meet these requirements, how much lower from that number should I make my original offer (knowing that there is going to be some back and forth between the seller and me)?
