Not really. If new suppy growth outpaces demand then prices will drop. Recent advances in robotics may make construction much less labor intensive, crashing prices in many areas.
Where is there a place where prices have gone down (and stayed down) in practice for a long time? I've been waiting for 20 years to get a "bargain" and except for a small area in the US and some very short lived downs elsewhere, that just never happens.
