How much money do I need?

[Todd P.]

I have been looking at doing a value play on a multi family (20 - 50 units or so). First thing I would like to know is how much money do I realistically need to bring to the table? I hear that sellers often will take back a second from 10-20% and a bank will loan 75-80%, if this is basically true and I have a nice paying job and decent credit do I need any of MY OWN money in a deal? If so, how little would I need? Can I even get this kind of financing if I'm going for distressed property that needs rehabbing? I just want to get a feel for what ballpark I am playing in, the bigger the better in my mind. Thanks in advance and if there are better ideas for doing this sort of thing please feel free to let me know how.
