Key ideas in Evaluating Real Estate Investments
- NOI excludes financing costs like mortgage debt service to measure asset performance alone
- NOI excludes income taxes and depreciation because they reflect owner tax status, not property ops
- Routine operational costs like management and insurance must be subtracted within NOI
- Typical residential multifamily operating expenses consume 35% to 50% of gross scheduled income
- A 20% expense ratio usually indicates deferred maintenance, omitted reserves, or unrealistic projections
- Underestimating baseline operating expenses inflates apparent NOI and disguises negative cash flow
- CapEx includes major systems like roofs and HVAC that require steady reserve accrual
- Operating expenses cover recurring maintenance required to keep units habitable daily
- Treating major replacements as surprise one-off events causes severe cash flow shortfalls
- Economic vacancy measures uncollected rent, free-rent concessions, and turnover losses
- Physical occupancy only counts leases signed, ignoring whether tenants actually pay
- Underwriting based purely on physical occupancy overstates gross operating revenue
- Cash-on-cash return reflects net annual pre-tax cash flow divided by total actual equity invested
- Negative leverage occurs when the interest rate on debt exceeds the property cap rate
- Excessive leverage increases fixed debt payments, driving cash-on-cash return down during downturns
- Expensive fixed components like kitchens, baths, and utility hookups absorb a baseline budget.
