do lenders allow secondary loans?

Is it feasible for a commercial lender to provide 80% financing and allow a secondary lender to finance the remaing 20% and closing costs?

Yes it is possible depending on the property usage type and if it will be for a owner occupied use.

Trump,

You will have to be very creative to get to 100% CLTV on a commercial property. Most lenders cap the CLTV at 90-95% with some seller second financing.

Christopher,

Is it uncommon for sellers to provide financing?

It seems to be very common especially in multi-family.
