It really depends on the asset and the borrower. It could be as low as 4-5% but the amortization period might only be 20-25 years instead of the 30 years that's more typical with residential loans. Also, almost all commercial loans have a 10-year call so you have to refinance within 10 years or pay off the remaining balance with a balloon payment. I've seen a few fully amortizing commercial loans, but not many. In general it's going to be higher than a comparable residential mortgage by 50-100 basis points.
