typical market participants, this approach is generally considered the most applicable valuation technique for income-producing properties, where sufficient market data exists. In a commercial income-producing property this approach capitalizes an income stream into a value indication. This can be done using revenue multipliers or capitalization rates applied to a Net Operating Income (NOI). Usually, an NOI has been stabilized so as not to place too much weight on a very recent event. An example of this is an unleased building which, technically, has no NOI. A stabilized NOI would assume that the building is leased at a normal rate, and to usual occupancy levels. The Net Operating Income (NOI) is gross potential income (GPI), less vacancy and collection loss (= Effective Gross Income) less operating expenses (but excluding debt service, income taxes, and/or depreciation charges applied by accountants). Alternatively, multiple years of net operating income can be valued by a discounted cash flow analysis (DCF) model. The DCF model is widely used to value larger and more expensive income-producing properties, such as large office towers or major shopping centres. This technique applies market-supported yields (or discount rates) to projected future cash flows (such as annual income figures and typically a lump reversion from the eventual sale of the property) to arrive at a present value indication. In Canada, reversion values typically range from 16x-21x the NOI of year of sale. When homes are purchased for personal use the buyer can validate the asking price by using the income approach in the opposite direction. An expected rate of return can be estimated by comparing net expected costs to the asking price. This return can be compared to the home owner's other investing opportunities. UK valuation methods In the United Kingdom, valuation methodology has traditionally been classified into five methods: 1. Comparative method. Used for most types of property where there is good evidence of previous sales. This is analogous to the sales comparison approach outlined above. 2. Investment method, also known as hardcore. Used for most commercial (and residential) property that is producing future cash flows through the letting of the property. This method compares the estimated rental value (ERV), or "top slice" to the current ("passing") income, or "bottom slice", to give an indication of whether the future value of the property should rise or fall based on income. If a property's income is higher than the ERV this is
