If the vacancy rates are good in the area im investing i dont need a 10yr guarantee. I also steer clear most development stock that has a rent guarantee as i run all my numbers on natrual yield. Plus the limited buyer pool should you need to sell, and i know everyone here states that "i wont be selling in ten years or im going to keep it for ten years" no one knows what will happen you may be forced to sell at some point. Everyone should be looking at investment with a worse case scenario mindset
