Look again at what you received. I suspect it says your property was sold at a tax sale. This is where the other bunch of bottom-feeders go to work. They pay the county the taxes due on the property then the county gives them a certificate. The certificate allows the holder (the bottom feeders) to foreclose on the property.
If you catch the problem before the foreclosure you need to pay the holder the taxes (which is fair) but you also have to pay their fees. The fees can be $3,000.00 or more for a tax sale of a few hundred dollars.
If they sell the property at public auction, the property is theirs in most jurisdictions. In a normal foreclosure, what ever is left over (the excess from the sale) is supposed to go to the property owner, but not when it is a property tax auction. Depending on your county, the foreclosure sale can be months or years after it is sold at a tax sale.
When you see the late night “Get Rich in Real Estate” info commercials, they are talking about the money to be made in tax sales.
Servicers have a pretty sophisticated system of keeping track of tax sales so that when one comes up they jump in and pay the taxes so they don’t loose their collateral securing the loan. Most pooling and servicing agreements make the top two most important requirements for a servicer is to be sure the taxes and insurance is paid. This is why most sun-prime loans do not have an escrow account. Not having escrow keeps two doors open for default and the fees that go along with it.
Hope this helps
