Tax deed sale process and surplus

[Carolyn Morales]

I am confused about how the surplus works. I went to an auction and there was a fabulous brick home in an affluent neighborhood for 23k starting bid. 2 men haggle each other to 166 k. The surplus is listed. Does that mean the successful 166k bidder gets the surplus back? Does it mean other people can apply for that surplus and upon what basis is surplus awarded? Also, are the truest investors marketing to owners on the tax deed list before the sale date? Please be kind...
