Lowest down payment on a multifamily?

[Bryan Cavellier]

I am curious to hear everyone's lowest down payment (%) on a Multifamily property (2-4 units). Obviously there is 3.5% with FHA, but are there any low government programs or random credit unions/savings banks that allow 0-10%? I am currently in an FHA loan so can't open another one (not looking to refi quiet yet), but want to buy another property (multifamily, 2-4 units). ANY and all suggestions, thanks!!
