Demand has stayed strong, and driven by low interest rates and people wanting larger homes, has also pur pressure on the demand side.So with lots of buyers chasing fewer and fewer homes, that creates an extremely hot market.If you want to be in investing for the long haul, you have to learn how to adapt to different market environments.

I can tell you a 50-65K move in ready house will be dangerous to walk outside in mid day.
