congrats on purchase. not all that familiar with the market there but records show your neighbor now trying for $815k bought during bubble summer 2005 for $684k, up from $465k in 2001. prop appraiser shows current market value at $588,432.
yours sold last for either $530k in 2003 or $83k in 2000 (my guess is that was before the house was built) in which case pa shows current market value at $682,762 but i suspect official pa values for tax purposes will be slow to come down to reality.
dq news shows that medium price in your zip code dropped 17.8% on its last survey of 3rd quarter 2007 year over year. average price per sq ft $208.
welcome to florida. good time to buy. bad time to sell. don't forget to file for homestead before (i think it is) march.
