Eligible to Borrow

I heard there was more that just the equity in your home that determined how much you could borrow. If so what determines what I will qualify for.

The amount of funds you are eligible to receive depends on your age (or the age of the youngest spouse in the case of couples), the appraised home value, interest rates, and in the case of the government program, the lending limit in your area. In general, the older you are and the more valuable your home (and the less you owe on your home), the more money you can get.
