Most deals are floating with today's high interest rates. Will probably go down but how much is the unanswerable question. I have recently completed one at 1% over prime (excellent small strategic buyer) to the maximum of 2.75% over.
Some bankers are trying to hit their numbers for the year right now as well, but too late to close byredactedBankers do consider equity, assets and experience into the rate. But your first quote is not bad.

I recently closed a deal a Prime + 1.5% (floating). I would stay away from fixed rates as interest rates have likely peaked and may go down over the next 3 years
