There is some serious disinformation floating around out there.
Statistically, the rent “decreases” everyone is hearing about are very small. These small decreases are, in my opinion, skewed by what is happening in parts of town you would not want to be caught dead in.
The press and the FED has everyone believing we have a deflationary spiral because the stock market and housing prices are falling but house prices and stock prices are not part of the CPI.
We are suffering modest inflation, hence your rent increase (although high) and in 5 more years or so it will be the 1970’s all over again.
