It is probably because whatever few technical challenges may exist in the real estate sector that software could aid are utterly dominated by the intractable problems posed by politics and regulation. We understand very well how to build housing, and we have understood how to build housing for a very, very long time, but for political reasons, because communities have been taken over by political interests that outright opposed to new housing we choose not to. You could come up with some novel construction technique that makes building homes more efficient, but it wouldn't matter if the city doesn't approve new homes to be built.
