You do not have to be an expert to realise that an accurate property valuation is extremely important. The accuracy of this valuation is determined by the property valuation methods that are used. At the very least it quite simply determines if you can or can not buy a house. It determines how much you are willing to spend on it and it also determines if the bank will or will not lend you the money to buy it.
For property investors the property valuation methods and total appraisal are even more important. For a real estate investor the valuation will determine his or her ability to continue their investing later. Equity and the ability to leverage later is the life blood of most property investors. This is particularly the case with residential rental property investments. This equity is determined by the original price paid for the real estate and the current value of the property. Both of these are determined by the property appraisal and valuation.
To determine this value the most popular property valuation methods used is the market data approach. This approach attempts to compare the property with similar properties in the area and find the value that way. Other property valuation approaches include the cost approach, which uses the cost of building and the cost of the land to find the total value of the property.
