This is kind of rewarded with long term leases; a business takes out a 10 year lease in a "cheap" neighborhood, does well, brings people to the area, they pocket profits on their cheap rent.

It's further compounded by sales intra-lease where the new buyer has modeled the rent once the current lease is up in order to justify the sales price.
