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.
There can be differences between what the property is really worth (market value) and what it cost to buy it (price). A price paid might not represent that property's market value. Sometimes, special considerations may have been present, such as a special relationship between the buyer and the seller where one party had control or significant influence over the other party. In other cases, the transaction may have been just one of several properties sold or traded between two parties. In such cases, the price paid for any particular piece is not its market "value" (with the idea usually being, though, that all the pieces and prices add up to the market value of all the parts) but rather its market "price".
The BauGB defines the Verkehrswert or Marktwert (market value, both terms with identical meaning) as follows: "The market value is determined by the price that can be realized at the date of valuation, in an arm's length transaction, with due regard to the legal situation and the effective characteristics, the nature and lay of the premises or any other subject of the valuation" (non-official translation). The intention, as in other countries, is to include all objective influences and to exclude all influences resulting from the subjective circumstances of the involved parties.
While no appraiser is infallible, his or her opinion of the value of your home is informed by rigorous training, numerous tests, several years of on-the-job experience and required continuing education. They are also required to substantiate every finding in their reports that could influence a home’s value. Appraisers and their employers (often appraisal management companies) are heavily regulated. Consequences of issuing deliberately misleading or biased reports can be severe, so appraisers work hard to remain impartial and keep personal value judgments and prejudices out of their work.
"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.
