That's actually a really good point to ponder about. I've seen a number of news articles about predatory practices among real estate agents (I believe many hog anywhere from 3 properties or more to ride the bubble, there's unethical abuse of dual representation, there's bid secrecy, etc) No doubt, there's also a great deal of greed and wealth signaling from the general population (especially among upper middle class) as well. Competition around high ranking school areas comes to mind. Not to mention rental properties are pretty much the go-to choice of passive income building that most people go for. I would bet that if multiple property ownership was penalized by high taxes, real estate prices would come down real fast.
