Does anyone rent their hives from the landowner?

I recently responded to an ad for a bee yard manager & what the landowner actually has is 10 empty beehives with supers, fully drawn comb and an extracting room (in their house). He has no bees anymore & is too busy to keep them himself. I had a nuc in a box & not enough equipment or space of my own to expand (I have 2 hives in my 1/2 acre yard.) We agreed that I would just give them a percentage of honey, but we didn’t know what that percent would be. Is there a going rate for people who already do this? I assume most people who place their hives on other people’s land own the hives & just use the land, so this would be rental of the hives too. Any suggestions?
