Buying 2nd property, but I really want a LARGE building.

[Chris Musser]

(Chicago) I have a 3 flat FHA, closing on a 2 flat under a 5% down loan, but I really want a LARGER building, but all I can usually come up with is 20k for a down payment. Credit is 800, but no way could I come up with 25%. Current building is doing well, I would just prefer not to run all over the city maintaining my properties. I need around 10 or so, or one big apt building. I need financing with a LOW down payment...any ideas? I could make it happen with 1M, maybe a little less.
