Lenders who allow Seller Seconds in Wisconsin?

[Pete Sailhamer]

I'm looking at buying another apartment complex in the southern Wisconsin area for between $500k - $1M.  The seller is offering up to 10% seller financing, but the trouble is finding a lender who allows additional liens on the property.  I would like 80% bank (or lender), 10% seller, and 10% me.  Does anyone have any good recommendations for lenders who accept this?  

Thanks!
