According to the article, landlords expect economic cycles to last 7-10 years, and the last bust was in late 2008. So the next bust can be expected to occur somewhere between late 2015 and late 2018.
It's already close to late 2015, so the halfpoint of the predicted period is only 18-21 months away. That fits your observation that landlords expect the bust to be less than 18 months away.
