Banking Experiences

I was reading this article by this real estate guru that I've been following for the last few years (Greg Habstritt) and the article really struck home with me. I recently spent the weekend with a banker and I believe I had the opposite experience. I found the experience very educational and shocking at moments, having learnt new and interesting ways to free up capital. I went in to ask about a line of credit, how it works etc. I found out that they can help me even though I haven't lived in my residence long. I learnt that they can give me 75% of the equity that I have in a line of credit and can do it at PRIME. Its also a floating prime that goes up and down with the lending rate. They can tie it to a credit card (which would be way cheaper than what I'm presently paying). I only have to pay the Interest rate as a minimum monthly payment. They can increase the line of credit as equity builds relatively easy, thus freeing more capital.
I can also see how for the individual that can't control their spending can get into a heaping load of trouble using their line of credit for consumer expendable good that have no real asset value.
I must admit I'm not a first class financial guru but I see that you've got to do your own research, because no one cares about your finances more than you.
