Obsene amount of unpaid property taxes

[Jon C.]

BP,

     I have a lead that has $37,336.99 worth of unpaid property taxes.  They haven't paid taxes since 1993.  The property is worth $163,000.  The original note from 1966 of $15,750 is paid off.  I have a few questions:  how has this property not gone to tax deed sale?  There are some liens from the IRS from the 1980's on file.  Does this make sense of wholesale?
