Answer:
First the bank will collect its $150,000 and then the county will collect $2,500 in unpaid property taxes.
Explanation:
Generally, liens get in line depending on the time that they were recorded (contractor then credit card) but property taxes have superiority over other liens even f they were recorded before. After the foreclosure, the liens cease to exist, but not the debt. The property will still owe $500 in taxes and the previous owner will still owe $3,000 to the contractor and $12,000 in credit card debt.
