Emaar, UAE’s biggest developer by market value, was hurt by a more than 60 percent slump in property prices in its home market as speculative demand waned and banks tightened lending since mid-2008.The company reported a 69 percent decline in second-quarter profit as it wrote down the value of a bank investment and delivered fewer completed homes.
