Most rate reset preferreds reset their dividend every five years. That can be a long time to wait for your income to increase, if in fact interest rates do rise. No one knows with any degree of certainty what interest rates will do in 2017 let alone in the years beyond that. Anyone who says they do is simply guessing and I'd suggest checking their track record on interest rate forecasting.  
Over time, you're far better off owning shares of companies that consistently raise their dividends than any kind of preferred share. At least that's what history says. Even if we do get a rising interest rate environment.
