Allowing foreigners to buy houses and land will for sure raise property values to the point that Thais will no longer be able to buy a home. Just look what happened to New Zealand when they did the same thing about 10 years ago. Rich Chinese came in by the bus load - on property real estate sponsored buying tours - some bought blocks of houses off the plans with little regard of price. This alone drove the price out of reach of most New Zealanders. Now the average price of a house in Auckland is over a million NZD. Before this change price was about $250K to 350K.
