When buying own property most people think it's all about paying off the loan as soon as possible. But the truth is whether you are only a home-owner or real estate investor it's never about paying off the loan as soon as possible. As a home-owner it's about quality of life - if you want to live your life fully you have to have enough cash-flow. So it's better to have low rates to pay for your rental in order to have enogh money to live. And as an investor it's also about having enough cash-flow to invest in more properties in order to scale up your profits. As right now money to borrow for rentals is so cheap it doesn't make sense to pay it off quickly.
