vacancy rates in greater KCMO

[Ryan Fox]

It's hard to come by unbiased data on this, but does anyone have any access to data showing rental vacancy rates in MO, per county?  I know there's been growth of housing supply in the KC area.  There's also a lot of units on the market for rent now, seemingly more than prior years, even considering it's the middle of winter.  Year over year comparisons would be helpful.
