The average nominal price of four-room apartments was 13.7% higher than in the corresponding quarter of 2009, and 29.4% higher compared with the fourth quarter of 2008. Yitzhaki noted that, during the fourth quarter. The Bank of Israel raised the interest rate and imposed restrictions on mortgages in an effort to reduce demand for homes.
