This parcel was listed in the MLS for $25,000. The listing was cancelled back in February, and it has not been re-listed in the Tucson MLS.
There are two other 1+ acre parcels on the same street currently available, both are listed at $30,000. Looks like the electric is in the street, gas is not available other than bottled propane, water is at the street or lot line, and both have septic tanks installed. Of course this is assuming that the listing information is correct. It's always important to verify all listing data. Hope this helps!
