Asking rent and area over time

#

Total rent = monthly rent + common charges; rent per unit area is that divided by area. Area is the variable between the two — a month where only the total moved is a month where the space on offer changed, not the price.

house — Asking rent (total) and Asking rent per ㎡ over time

Asking rent (total) = the median of monthly rent + common charges. This is the payment per unit itself, so floor area feeds straight into it.

Asking rent per ㎡ = (monthly rent + common charges) ÷ area. The monthly rent per square metre, derived from properties currently on offer.
