Lol.... sounds like another half baked idea that will punish those trying to get ahead, and would be another beurocratic nightmare. How about we just let the market do what the market will do and let if find it's own balance. Adding additional controls on lending to promote safer lending is more than enough. If you want to control speculation then change the CGT rules to reward those holding for longer periods of time and make it less attractive to flip within a short period of time.
Also since we are so concerned about investors driving prices up then this policy must also apply to the stockmarket after all everyone that invests in a company ultimately wants to get a good return which means companies have to do everything to increase their margins which again overtime in most cases means product prices increase.
