Rents going up in Chicago?

Rent vs. buy is a little bit out of whack here in Chicago.

Of course the media spin is that the rent/buy gap is narrowing, but look at the numbers. Its up 3% from the lowest been in at least 15 years.
Would you want to buy when you could rent for 60% of the price? Would you want to buy with the real possibility of losing 10-20% over the next 5 years?
The numbers are likely reflecting landlords increased property tax payments. Some secondary factors could be higher mortage costs putting pressure on landlords who own property with ARM's, and landlords who purchased rental property in the inflated price world of the past 4 years.
