If you own a leased commercial building, the income approach gives you a starting point: annual net operating income divided by a market supported capitalization rate. NOI is rental and other property income after vacancy and operating expenses, before mortgage payments and income taxes. Your rent roll alone cannot establish NOI. Reconcile the leases with collections, then account for taxes, insurance, maintenance, management, and the expenses the owner actually pays. A building can show full occupancy and still collect less than its scheduled rent. Keep the current operating statement separate from a proposed budget so a buyer or lender can see which numbers are actual and which depend on changes you have not made.
The cap rate must come from properties a buyer would reasonably compare with yours. A leased industrial building and a vacant office conversion do not carry the same operating risk. Location, tenant credit, lease duration, building condition, and the need for additional capital affect the comparison. A lower cap rate produces a higher estimate for the same NOI, but choosing a lower percentage does not make that estimate supportable. Use the property value calculator to test the arithmetic with your own inputs. Its result is an income based planning estimate, not an appraisal, a sale price, or the amount a lender will advance.
The sales comparison approach checks what similar properties actually sold for. You need the transaction date, property size, condition, occupancy, and the circumstances of the sale, not just an advertised price per square foot. A fully leased building sold with a long tenant commitment may not be a useful direct comparison for your building with a lease expiring. The cost approach considers land value and the cost of replacing the improvements, with appropriate deductions for depreciation and obsolescence. It can inform the assessment of specialized buildings, but replacement cost does not establish what buyers will pay for an obsolete layout or weak location.
If the property is vacant, planned for renovation, or partly leased, separate its current condition from its proposed stabilized operation. Show the remaining work, expected cost, lease assumptions, and the time during which expenses continue without full rent collections. A lender appraisal may consider more than one valuation approach, and the appraiser decides which approaches are appropriate to the assignment. Do not present a future fully leased value as today's collateral value. A bridge request can involve the current asset and the proposed business plan, while permanent financing usually depends more heavily on supportable ongoing cash flow.
Before you request a commercial mortgage, collect the rent roll, leases, operating statements, property tax information, and details of repairs or capital work. Your financing analysis must then address value and debt service separately. Even if the value supports the requested loan, the property's cash flow may not support its payments. Use the DSCR calculator to test coverage and the maximum commercial loan calculator to compare the constraints. CapitalAx reviews your property and financing request as a broker. The lender determines appraisal requirements, credit terms, and approval. None of these planning calculations replaces an independent appraisal.
