North Miami Beach liens any chance of negotiating?

[Elvis Vasquez]

A friend is looking to purchase a vacant lot for around 10k however it has over 150k worth of liens City of NMB code enforcement (the liens   were placed on a bulk of lots since the previous owner never kept up the lots).

From what we read in the title report the actual liens pertaining to the property is only around 6k however the "bulk" lien placed on all vacant lots is around 150k.

Anyone ever deal with this before?
