Using HELOC on a subject to deal possible or not?

[James Mercer]

Hypothetically, if I took over someones existing mortgage subject to and owned the property cause I have the title now, would I be able to get a home equity line of credit or equity loan on that property if it had a good amount of equity? Do I have to get lines of credit or equity loans from the same bank or can I have a mortgage with one bank and a HELOC with another bank for the same property?
