The scope of work is the first step in any appraisal process. Without a strictly defined scope of work, an appraisal's conclusions may not be viable. By defining the scope of work, an appraiser can properly develop a value for a given property for the intended user, and for the intended use of the appraisal. The whole idea of "scope of work" is to provide clear expectations and guidelines for all parties as to what the appraisal report does, and does not, cover; and how much work has gone into it.
In most instances when the cost approach is involved, the overall methodology is a hybrid of the cost and sales comparison approaches (representing both the suppliers' costs and the prices that customers are seeking). For example, the replacement cost to construct a building can be determined by adding the labor, material, and other costs. On the other hand, land values and depreciation must be derived from an analysis of comparable sales data.
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.
Automated valuation models (AVMs) are growing in acceptance. These rely on statistical models such as multiple regression analysis, machine learning algorithms or geographic information systems (GIS).[17] While AVMs can be quite accurate, particularly when used in a very homogeneous area, there is also evidence that AVMs are not accurate in other instances such as when they are used in rural areas, or when the appraised property does not conform well to the neighborhood.
I just wanted to let you know how helpful Mike Nichols was in helping us through a complicated situation in a real estate transaction where a tax certificate had been sold on the subject property. He went above and beyond the call of duty, patiently explaining the situation separately to all three parties involved. The issue was resolved with his help and his response was excellent.

Appraisals can be assigned to nearly any item, including real estate. Appraisals are conducted by individuals called appraisers. Appraisers are educated in a variety of market valuation methods and are recognized by a regulatory authority as being capable of issuing an accurate valuation. For instance, an appraisal on an antique will take into account such variables as age, condition, origin, and availability of authenticating documentation.
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).

Lenders want to make sure that homeowners are not overborrowing for a property because the home serves as collateral for the mortgage. If the borrower should default on the mortgage and go into foreclosure, the lender will recoup the money it lent by selling the home. The appraisal helps the bank protect itself against lending more than it might be able to recover in this worst-case scenario.
