The cost approach was once called the summation approach. The theory is that the value of a property can be estimated by summing the land value and the depreciated value of any improvements. The value of the improvements is often referred to by the abbreviation RCNLD (for "reproduction/replacement cost new less depreciation"). Reproduction refers to reproducing an exact replica; replacement cost refers to the cost of building a house or other improvement which has the same utility, but using modern design, workmanship and materials. In practice, appraisers almost always use replacement cost and then deduct a factor for any functional dis-utility associated with the age of the subject property. An exception to the general rule of using the replacement cost is for some insurance value appraisals. In those cases, reproduction of the exact asset after a destructive event like a fire is the goal.

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.


The various U.S. appraisal groups and international professional appraisal organizations have started collaborating in recent years towards the development of International Valuation Standards. This will facilitate global real estate appraisal standards, a much-needed adjunct to real estate investment portfolios which cross national boundaries. Some appraisal groups are already international organizations and thus, to some extent, already incorporate some level of global standards.
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).
Unfortunately, recent distressed sales in the surrounding area can lower your home's appraisal value. If you feel that your home's value has been dragged down by the sales prices of nearby foreclosures and short sales, you may be able to convince the appraiser that your home is worth more if it's in significantly better condition than those properties. Sellers should also know that federal guidelines (intended to eliminate the inflated appraisal values that contributed to the 2008 housing crisis) sometimes cause appraisals to come in below fair market value and can make low appraisals difficult to challenge.
