Price-to-rent ratios are useful, but somewhat flawed

They give a general idea about house prices, but there are other important factors (like inventory levels, price to income and credit issues). We are getting closer on prices, but it appears we still have a ways to go.

One thing is pretty certain - as long as inventory levels are elevated, prices will continue to decline. And right now inventory levels of existing homes (especially distressed properties) are near all time highs.
