As income investors, we want to own stocks with high and safe dividend yields, but the best stocks to buy are those that can also grow their payouts over time. With this in mind, I’ve scoured the market and compiled a list of five stocks with yields of 4-7%, active streaks of annual increases, and the ability to continue growing their payouts going forward, so let’s take a quick look at each to determine if you should buy one or more of them today.

1. Plaza Retail REIT

Investors must also note that the company has raised its annual distribution for 12 consecutive years, and the 4% hike it announced in November 2015, which was effective for its January 2016 payment, has it on pace for 2016 to mark the 13th consecutive year with an increase.
