Any lenders doing 20% down on a non-owner occupied duplex?

I'm in Colorado looking at investing in duplexes for the most part. Every lender we've spoken with is requiring 25% down for small multifamily, including duplexes, since we are not planning to live in the property but will still allow 20% on SFR. Anyone know of lenders that are doing small multifamily for 20% down? Who has the best terms right now?
