I agree with @David Krulac - hopefully your property is in one of the 2% RTT areas rather than one of the 4% or 5% RTT areas.The imputed property value used to determine the RTT amount can be found by taking the tax assessed value from the tax assessor, and multiplying (or dividing) by the common leveling ratio that the PA Department of Revenue has posted at their website, for the year and month of the transfer (the values in their table change over time).Once you have that value, and the tax rate for that location, you can figure out how much this screw up cost you ;)
