How do you find good apartment building deals?

[Ben Feder]

I know when it comes to SF and small MF you can look for motivated sellers through list sites, but how can you find a good deal when it comes to apartment buildings? Are there motivated sellers when it comes to apartment buildings (5+ units, possibly around 30-50 units, maybe more)? Are there foreclosure bargains to be had? What criteria are there for buying apartment buildings? Any input is appreciated as always.
