Continuing a tradition as strong as your grandpa?s spiked eggnog, Newmark Grubb Knight Frank market analytics national director Bob Bach once again compares the cost of a holiday meal to the economy?s performance. The good news: Your feast is up just a modest 0.6% from last year, averaging $49.48 to feed 10 people. Bob says since 2000, the cost of a turkey dinner has risen 53%. But from 2000 to Q3 ?12, the NCREIF Property Index gained 159%, trouncing the Moody?s/RCA Commercial Property Price Index (which measured CPI up 34% and CRE prices up 43%). For that, he's grateful.
