A huge problem here - and why some people stopped buying homes on auction - is that homeowners are filling sinks and drains with concrete powder before moving.
You buy the home on bank auction - you don't know what you're getting.
You don't know if the last guy punched holes in wall, destroyed drains, broke all the windows, etc etc. People know it's THEIR house until the bank comes, and they trash it sometimes.
At least this way, $ sitll comes in, the bank gets their house, the family doesn't end up on the street, and hey, they don't keep the house they couldn't afford in the first place.
