Rental properties introduce another set of questions alongside the physical property and comparable sales. Are the rents supportable? Which expenses belong in the analysis? Does the reported income reflect recurring operations? A result is only as useful as the assumptions supporting it.
A simple illustration
A capitalization rate expresses the relationship between a property’s net operating income and its value. Dividing net operating income by a capitalization rate gives an indication of value, so a small change in the rate can change the result considerably.
- Annual gross income: $82,000
- Operating expenses: $30,000
- Simplified net operating income: $52,000
- At a 10% capitalization rate: $52,000 ÷ 0.10 = $520,000
- At an 8% capitalization rate: $52,000 ÷ 0.08 = $650,000
Check the inputs
Review rent documentation, occupancy information, relevant expenses and the treatment of repairs or unusual income. A scheduled rent and a collected rent may tell different stories. An expense total without an explanation may conceal important differences.
Use market support
A capitalization rate should not be chosen simply because it produces a desired value. Both the income assumptions and the analytical method need relevant support. Comparable sales may still contribute to the overall analysis.
For an actual assignment, the appraiser determines the appropriate analysis within the agreed scope and applicable requirements. Provide reliable property information early and ask for clarification when an assumption is unclear.
