I have a parking spot assigned to my condo that isn't being used. I won't say exact location but it is 1.5 blocks (south direction) of 17th Ave and 4th Street SW. The stall has an electric outlet for the winters, but is not secured.
the only person that can tow you is myself, and I never have problems with people using the spot without consent.
I was thinking $140 per month but willing to negotiate if you will pay several months at a time. let me know if anyone is interested.
