In order to be fairly taxed, homeowners in Florida must have their property accessed by the county property appraiser at least every five years. That does not however mean that the value of the property will be increased every five years. The Monroe County property appraiser places a fair market value on property within the county and that could mean that the value of the property has decreased, just as it has in many places in Florida. There have been houses that have been damaged due to hurricanes or flooding and those values have decreased. There were also houses built with contaminated drywall which are currently appraised at zero by the Monroe County property appraiser until the problems can be fixed. Besides the special circumstances which may have lowered the value of properties in Florida, there has also been an enormous decrease in the sales of properties throughout the state, which has resulted in a decrease in the value of many properties throughout the state. There are standard rules which influence the value of properties as determined by the Monroe County property appraiser. For example, the size, location and upgrades on a piece of property, all influence the fair market value of that property. The rules which govern how much those factors influence the value, are standard across the state.
