Question 1

How is NOI calculated?

Accepted Answer

NOI calculation: Step 1: Gross Potential Income (GPI): the total rental income if the property were 100% occupied at market rents. Step 2: Subtract Vacancy and Credit Loss: the estimated income lost to vacant units and uncollectable rents (typically 5-10% of GPI). Step 3: Effective Gross Income (EGI): GPI minus vacancy = EGI. Step 4: Add Other Income: laundry, parking, vending, storage, and other non-rental income. Step 5: Subtract Operating Expenses: all expenses necessary to operate the property. Result: NOI = EGI + Other Income - Operating Expenses.

Question 2

What is a common mistake in NOI calculations?

Accepted Answer

Common mistakes: including debt service (mortgage payments are not an operating expense; they are a financing cost), including capital expenditures (roof replacement, HVAC systems; these are capital costs, not operating expenses), using actual income instead of market rents (the calculation should reflect the property’s potential at market rates), ignoring vacancy (assuming 100% occupancy is unrealistic), understating management fees (even owner-managed properties should include a management fee to reflect the true cost of operations), and inconsistent expense treatment (some expenses may be one-time costs that should be excluded or adjusted).

Question 3

How does NOI differ for different Florida property types?

Accepted Answer

Property type differences: multifamily: vacancy rates typically 5-8% in Florida; operating expenses include unit turnover costs, landscaping, pool maintenance, and amenity costs. Retail: vacancy depends on market conditions; CAM charges may be recovered from tenants (affecting the NOI calculation). Office: similar to retail; operating expenses include elevator maintenance, lobby services, and higher utility costs. Industrial: typically lower operating expenses (tenants handle most maintenance in NNN leases); vacancy rates depend on the market. Each property type has different expense ratios and cap rates.
