more like $400/mo. Going price for a parking spot in SF (generally, across the city) is about $200/mo.
Donald Shoup would be proud. Free parking is generally a menace to cities.
I'm not sure that holds true for all streets, especially a private street in a residential area. Suppose there were no problems with parking before - what do you get by introducing a charge suddenly?
Parking spaces go closer to $200+ so that would yield $24,000 a month. Not a bad ROI from this real estate investment! Time for me to go check out this city auction business.
