Property players have turned much more negative on the outlook for the prime residential sector, after two rounds of market cooling measures took effect, a recent poll found. Real estate executives also flagged macroeconomic risks as top concerns, in the quarterly survey conducted by Institute of Real Estate and Urban Studies (IREUS) at the National University of Singapore (NUS). In the second quarter, prime residential was the worst performing sector in IREUS' sentiment index survey, with a negative net current balance of 40 per cent. The sector also scored the worst future net balance among respondents, at negative 28 per cent.
