If you live in a Democrat-run city or county and have a mortgage, ask your lender to stop escrowing your property taxes, and then put the money in a CD and delay paying the tax as long as you can. A local real estate agent tipped me to this one. She said our township is terrible at collecting unpaid property taxes and often takes over a year to do it.
In fact, watch yourself on all tax tricks. There isn't much that has not been tried. Most tax delay/avoidance schemes are well known to taxing authorities and some can have costly consequences.
