I bet that block of 4 newer 3 storey townhouses on the 1500 block of W Canfield with an opening bid of around $30K-$40K a piece is another large landlord like Cusimano trying to write off huge back taxes.
If anyone's looking for some really nice student rentals, those look like ones well worth bidding on.
They are not vacant lots in the satellite view, but here's the addresses.
