DSCR (<5 unit) interest rates versus commercial rates

I've got a few 30 year DSCR loans on duplexes and typically got them at about 20-30 basis points more than 30 year traditional mortgages were going for the time. The current going rate from my lender for a DSCR on a duplex is about 7.0-7.2%, give or take.

I'm trying to move up to 5-20 unit multifamily and will need a commercial loan instead. How do those rates compare to DSCR and traditional resi mortgage rates? Are commercial loan rates on small multifamily signifiantly higher?
