When a bank takes a property back through foreclosure the house loses it's homestead and the taxes increase. Once you own the house you can appeal the taxes but the local taxing authorities only give you a small window of opportunity, typically only a couple of weeks, once a year and for most that time has passed so you'll have to wait until next year to appeal. There are several good tax appeal companies and law firms that charge reasonable fees to work through the appeal process, I wouldn't advise trying to do this yourself, leave it to the experts. I've had clients cut their taxes in half after the appeal.
