Home Equity Line of Credit - Should We Avoid It or Use It?

The mortgage lender has talked about a financial product i've never heard of before. It's a 30 year draw home equity line of credit with an integrated sweep checking account. Concept is, every pay check you make goes into this joint account that's a debt and credit so you have your money, and then you have the money you owe. The idea is that every time you get a pay check or any money deposite into the account, it lowers the balance on the home Equity line of credit. And then as your expenses mount during a month and you pay your various bills, then the balance onthe heelock goes up. So just keep it simple, stay away from this goofe product
