Is refinancing at this time right for me?
The best thing you could do is see what yoru total payments are over the course of 10 years and then compare that total to how much you will pay over the course of the 7 remaining years on your current mortgage. Chances are your are paying Interest Only on the Heloc so you would have to adjust the payment...

How soon can I refinance?
It is possible to do a FHA Streamline refinance after you make your 6th payment on your current FHA loan.

I am trying to find out information on a house with BAC Lender Services as the lending agent.
According to Bank Of America's REO website, This home is not listed for sale. The Harris' also are associated with 314 Newport Avenue so you may be able to speak with them directly and ask if the home is for sale.
