As Used in the Income Approach -- A procedure combining information from an operating income statement and sold market data which, when applied to a net stream of monthly income, creates a multiplier for sold comparables. To establish the multiplier, divide the net monthly income by the sales price of the comparable. For example, a comparable sale has gross monthly income of $2,000. The expenses for the month are $1,400. ($2,000-$1,400=$600 net monthly income.) Next divide the sale price of $50,000 by the net monthly income ($600). This provides the net income multiplier of 83.33.
