rates for conventional mortgage MFH

[JC Smith]

Hello!  I'm looking at purchasing my first MFH soon (duplex or triplex) via a conventional loan.  I got a quote from a local Minneapolis lender which was 25% down and 5.625% interest rate, no points.  Should I keep shopping around or is that good?  I've read some people can have found lenders who will do 20% down, which I would prefer- but just wondering if times are changing and 25% is the norm now.  Also, I've heard people on here talk about purchasing a small MFH through a commercial loan- any thoughts on that vs conventional?  Thanks!
