Rome, February 15 - The housing crisis in Italy will continue well in 2013, after sales prices fell by 12% in 2012, the federation of real estate agents said Friday. Since the global economic crisis that took hold in 2008, housing transactions have dropped a whopping 40%, said the organization. And since 2008, prices have slipped an average of about 25% per year, Fiaip added. Rents also slipped last year, by about 5.6%. Downward pressure will continue in the first half of this year, with a mild recovery in the second half that could see 2013 values end at about the same level as in 2012, said Fiaip.
