I was also getting credit card balance transfer offers at 0% promotional rates for a year to a year and a half and I started transferring my HELOC balances to the promotional credit cards.

We are out of state but would be open to working with someone local if they can offer favorable terms.2) Any local realtors you have worked with and been happy with?
