Here's the dilly
A Home equity loan is just that, a loan. If you apply for $60g's they give you a check for $60g's it is paid off over a long period of time and the interest is tax dedectible.
A Line of Credit is like a credit card. Apply for $60g's and use 5 you are down to 55g's to use. Pay back the 5g's and you have 60 to use again. This is what I have on my house. You can usually only draw on it for 5 years then you have 15 to pay it back. It is a little more compicated than that but I hope you get the idea.
So, there is no "good or bad". I took out the HELOC to work on the house and ended up paying off lots o' debt and didn't do much with the house. But If I had gotten a loan that would be the end. If I hit lotto, I can pay it back, buy a new GTO with the HELOC and be happy!
