Mortgage rates

I made an appointment with a mortgage broker for next week. At current rates, and for the payments I can afford, I should be able to pay off the debt in about 11 years. Last night I was exhilerated. The concern is, of course, whether I can continue to afford those payments without any job security or significant prospects beyond next winter. And rates seem poised to rise soon. My emotions change drastically from one day to the next.
