I am against "speculation" on any sort of real estate. On other hand I am not against real estate investments. And I don't think single family housing deserves any kind of special treatment.
I see no reason why someone providing capital to build a building and then renting it out to cover cost of that capital, maintenance and building cost is unreasonable or bad thing.
Issue really is when market is manipulated to keep prices going up beyond inflation or normal changes in demand. That really ruins everything. Real estate shouldn't really appreciate at all over time beyond inflation.
