"What the market will bear" is a big factor.Yes, but in this case there is consciously tailoring prices to local clientele.
I'm reminded of what some university students used
to whine about...."You charge more than it costs!"
Duh.
Why invest money, labor, & risk in property, only
to lease it out for no return, eh. I charged as much
rent as I could get....not always as much as it cost,
but usually more.
If ever you give up the life of a drone (employee)
to become a business owner, you too will want
to charge more than it costs.
