If the federal government taxed property tax at a very high level, but then said that 100% of the federal property tax rate was deductible from federal tax, anyone who is paying federal tax, would not pay anything. But those who own, or live in multi-million dollar homes, and are foreign buyers or tax evaders, would finally start paying substantial amounts to this economy. If you own a multi million dollar property and aren't paying federal taxes, somehow you are skirting the system, and must be forced to pay! Unless of course, you are retired.
