In regards to losing homes, just take a look at the YDR when they advertise the Sheriffs sales. There are many going on in the area. Some are estate sales, some are due to bankruptcy for other reasons. Many are due to tax deliquency.
You can also down load and read through the tax deliquency list from the county. The list is pretty extensive and a lot of SESD homes are on there.
