I see this kind of justification a lot in San Francisco - people glimpsing into the future and seeing what sells and what doesnt sell.
There are many many lots in San Francisco which have been vacant for years. This is more due to restrictions on development - then what would sell for that spot. Ground floor units in one rincon - mere feet from the freeway are selling for over 1 million - lets not underestimate the demand for housing in SF.
