What is a cap rate and how is it calculated?
Cap Rate = (Net Operating Income / Property Value) × 100. NOI = Gross Rental Income - Vacancy Loss - Operating Expenses. Operating expenses include property management (8-12%), maintenance, insurance, property taxes, but NOT mortgage payments. Example: property worth $500,000, gross rent $60,000/yr, 5% vacancy ($3,000 loss), $18,000 expenses. EGI = $57,000, NOI = $39,000, Cap Rate = 39,000/500,000 = 7.8%. Cap rate is the return you'd earn if you bought all-cash. It's the single most important metric for comparing investment properties regardless of financing. A higher cap rate means higher potential return but often higher risk. In 2026, average cap rates vary: multifamily 5-7%, office 6-9%, retail 6-8%, industrial 5-7%.
