Effective Rent Calculator (Free Rent Months)
Net effective rent after free months and landlord concessions — the number both sides actually negotiated.
Formula
Landlords defend face rents (they set building valuation and comps) and concede in free rent and TI instead — concessions are invisible in headline comps. In soft markets effective rents run 10-20% under face; always negotiate and compare on NER.
