You're right, 30ashopper. Property taxes in FL are set legislatively based upon home value as of Jan 1st each year. Mills can vary, obviously. But, since home values have dropped dramatically, that is the reason property taxes have declined in FL.
FF2, in the City of Atlanta, there hasn't been a flight from the City Limits. Over the last decade, there has been an influx of people moving into the City. Our taxes have increased in the last couple of years due to the declining economy, increase costs of services (yet police and firefighters have been furloughed) and a decrease in property tax collection ratios (collected:values assessed). Just like Walton Co., there was a huge increase in property values 2004-2007 and budgets were determined by these proposed values, which were obviously inflated. More than 50% of our tax base goes to the public school system, which I am huge proponent of; however, more teacher/school admin lay offs have already been announced.
In other words, municipalities are upside down with their respective communities and those left paying the bills are those who CAN pay them. It's a mess.
