In most states real estate property taxes can go unpaid for a period of 3 years before your house is put up for a tax auction and sold off for the unpaid taxes.
If the property is vacant and no house is on the property then the property taxes can go unpaid for only 2 years before they put your land up for tax sale.
So if you can come up with the property tax payment before the tax auction then you can save your house from getting sold at a tax auction.
I once went 3 years total without paying my property taxes on my house and then got a notice that if I didn't pay the taxes then the property would be sold at a tax auction.
I paid the full amount of taxes and other late fees and brought the house out of tax sale.
It's best to put money into a savings account just for your property taxes or put money in a separate checking account and set aside monthly payments into that bank account so that you have enough money to always pay the property taxes.
