【明報專訊】THE PREMIUM ARRANGEMENT of the new Home Ownership Scheme (HOS), which Donald Tsang unveiled last Wednesday in his policy address, is quite problematic. According to him, the subsidised portion of a unit's purchase price will be regarded as a loan and, when its owner sells it, he may pocket the value increase of that portion. He may use the money to "move upwards" - to buy a flat from a private developer. The government would practically give the new HOS flat owner another subsidy to help him to buy a private housing unit or even speculate in property. If it does so, it will depart from the principle of using public money to help citizens to buy their own homes. That is far from right.
