Why only official sources
Auction listing sites often copy each other, and dates go stale. We read the county or state agency's own page, note the date we checked it, and link you straight to it. The auction sites agencies use get a link so you can bid, but we never take dates or details from them. Before you bid, always read the agency's terms of sale. Tax-defaulted property is sold as-is, and the agency's rules and deadlines are what count.
