The basics
What surplus funds actually are
A house is sold at a foreclosure auction or a tax sale. The county takes what it is
owed: the unpaid loan, the back taxes, the fees and the costs of the sale.
Sometimes the property brings in more than that total.
That leftover amount is called surplus funds, or excess proceeds
depending on the state. In most places it does not belong to the county, and it does
not belong to the lender. It belongs to the person who owned the property.
The difficulty is that counties rarely come looking for you. The money sits in an
account under a case number. There is usually a filing deadline. And in many states,
if nobody claims it in time, it is absorbed by the county or turned over to the state.
If you lost a property in the last few years, it costs you nothing to find out
whether there is money sitting in your name.
