@Maggie Tasseron,
I've spent some time in your area too. Lots of windmills.
I did the same thing. When USAA, of all people, froze my wife's HELOC I maxed out my other three and deployed the funds. Since my interest rates are only at prime give or take half a point I didn't want to get locked out of them. I almost stopped doing business with USAA over that. They froze it the month after I paid it off and I had plans for that money. If I'd known they were going to do that I would have paid down other debt instead. Alas, I understand their position, I just don't agree with it. They used to look at those things on a case by case basis and focus on doing what was right for their customer. They are not the same company anymore, though. They just froze my HELOC when I refinanced. Wouldn't let me refinance without agreeing to the freeze. Irks the crap out of me, but I maxed it a long time ago and at 3.4% won't be paying it off any time soon. That money is earning much more than that in the properties I bought and excess cash is better suited to reinvestment or other higher interest debt.
I have a HELOC with Nexity, now AloStar, bank that they froze, but I had it maxed at 3.25%. And I have a HELOC with WF at prime as well that I thought they froze but when I refiannced that property earlier this year they said that not only was it not frozen but the draw was ten years longer than I thought. Good to know. All of those where opened before the crash. They cost nothing to open, had incredible rates, high LTVs, and no annual fees. I haven't seen deals like that anymore. My last one was in 2010 with Fulton Bank. Ironically, their mortgage arm forced me to buy a property, duplex, that my wife was living in as an investment property, but their banking arm allowed me to get a HELOC as though it was a primary residence. They went to 90% LTV but at 5.75%. I agree with @Jeff Pollack, take as much as they will give you. Having access to an additional $30k of my equity has already paid off, vice getting 1%-1.5% less on the rate. Just be smart how you use the money. I did have to pay $400-$500 for that line but it is more than worth it for access to the funds. No annual fee.
I was shopping for another HELOC on a primary residence in 2013 but the landscape had changed dramatically. I bought a property free and clear, HUD foreclosure, and intended to just get a HELOC on it but quickly realized that wasn't possible anymore. Oops. I am in the process of including that with some other properties to get a portfolio loan, thereby pulling some money out and getting two more mortgages out of my name.
@Brandon Hall, Thank you for the clarification. I have only used my HELOCs for RE investing so while I am sure it came up early on with my CPA, I did not remember that distinction.
