As mentioned before, an appraiser can generally choose from three approaches to determine value. One or two of these approaches will usually be most applicable, with the other approach or approaches usually being less useful. The appraiser has to think about the "scope of work", the type of value, the property itself, and the quality and quantity of data available for each approach. No overarching statement can be made that one approach or another is always better than one of the other approaches.
In the United States, the most common usage relates to real estate and personal property appraisals, while the term is often used to describe a person specially appointed by a judicial or quasi-judicial authority to put a valuation on property, e.g. on the items of an inventory of the Tangible Property of an Estate (IRS law) of a deceased person or on land taken for public purposes by the right of eminent domain. Appraisers of imported goods and boards of general appraisers have extensive functions in administering the customs laws of the United States. Merchant appraisers are sometimes appointed temporarily under the revenue laws to value where there is no resident appraiser without holding the office of appraiser (U.S. Rev. Stats. § 2609).
In most instances, an appraiser will spend their time determining the value of one piece of property at a time. Building up their expertise in making their assessments often leads appraisers to specialize in a particular area of real estate. For example, a commercial appraiser could focus on the market for office buildings, hotels, retail locations, and other properties that include an income generating quality.
"What is my house worth?" These real estate appraisers can answer that and much more all over Pinellas County. Whether it is appraising your home for a property tax appeal if your property taxes are too high, valuing your home for estate work or a divorce or helping you secure a HELOC, a local appraiser is best. They obviously also appraise new construction homes as well as existing homes, and can do it for a home listing, before or after a sale. They use the local MLS (Multiple Listing Service) to gather data on sales and listings and use them to professionally tell you what the price per square foot should be for your home and others in your area. They also can determine if there's any effect on the value of your home from pending foreclosures, REOs, and other "short sales" in Pinellas County. A licensed and certified appraiser's estimates of value on residential single family homes, condos, townhouses and more are much better than what you'll find when using an AVM (automated valuation model) or a BPO (Broker Price Opinion). They can do an appraisal for VA, FHA, conventional, jumbo, and Fannie Mae or Freddie Mac purposes, and routinely provide those reports on URAR, drive-by, and 1004 MC (1004 Market Condition) forms as well as others.
