Well, no, if the interest is very low, you can use the money to make you more money. You can also calculate inflation into the debt at least if you have fixation. But it really depends on the overall economy and interest.
I live outside of USA so i do not know what exacly is the situation in your Country/State. In my country, I would not buy real estate right now, no matter what. The city I live in has a decreasing population, and basically everyone is moving to the biggest cities, but when one looks at prices, it does not reflect it. One should take this also in mind before one buy real estate. How does the local Economy look, safety, future, population decline, etc.
