Property management has been concentrating on occupancy rates for so long that it is the major prey in their sights, yet a larger more telling one is standing right in front of them. Visible numbers only (VNO) is a term the author uses to describe numbers that companies watch, even though they have little or no bearing on true profitability. Occupancy is a VNO that represents an unreliable measurement because it is easy to calculate and understand. By teaching employees to only watch occupancies, you teach them to disregard the lifeblood of your business: Net rent revenue, effective gross income, net operating income and cash flow, along with valuation and return on investment calculations. Since employees are the heart of your company, it's important to keep them informed.
