Healthy home sales kept the US Housing Recovery on track, though fast rising prices and jitters about the broader economy could crimp buyer demand in the coming months.Worries about the economy dented consumer confidence this month,including a drop in in the number of people saying they planned to buy a house in the next six months. Earlier this year, a number of housing experts has expected price growth to slow as buyers reached the limit of what they could afford. But recent indicators suggest that buyers are unlikely to get relief soon. Month-over-month price gains were modest, giving some indication that momentum may slow heading into 2016. Miami had lower prices this month than last and 10 other cities saw smaller increases in December compared with November. Home prices are likely buoyed by low mortgage rates.The average interest rate on a 30 year fixed was 3.65 compared with 4.01 at the end of December.
