Least Affordable Housing Is In Mumbai: Study

How long would the average New Yorker have to work to be able to afford a luxury 1,076-square-foot apartment in Manhattan?

About half a lifetime, according to Bloomberg.

And that's not long compared to cities like Shanghai and Mumbai, both of which have the least affordable home markets for locals.

Bloomberg used data from a housing index by international property consultancy Knight Frank LLP and measured it against national income figures from the U.S. Central Intelligence Agency to create its tally of most expensive cities.

In Mumbai--the least affordable city on the list--the average Indian would need over three centuries worth of earnings to afford a 1,076-square-foot apartment, which in the commercial capital of India costs approximately $1.14 million, Bloomberg calculated.
