1. job growth: more demand than supply
2. the real estate cycles: recovery, expansion, hyper supply and recession with supply of rentals as an important indicator
3. leverage: getting debt. Say you buy a property for $1M, put a 30% mortgage and through forced appreciation increase the value by 10%, you went from $1M to $1.1M or from $300k of invested capital to $400k ie 33% increase
