Young woman unsure what to do with remaining loan.

I'm not sure if this is the best place for this is here, but, a young woman I know received a house from a trust after a family member passed. It has a HELOC. I believe it is for around 45K. She has enough to pay it off but is unsure if that makes sense. I don't think she has a lot of $ left if she does that. She has great credit if that helps. She is wondering the best way to pay it off that would make the most sense. I realize that may be difficult to answer without interest rate info.

She has another small home of her own with a loan. I don't know any of the interest rates or loan balance on her home. I'm assuming her primary loan rate is low because she purchased it several years ago.

I asked what the HELOC rate is and the bank won't tell her until they receive the letter of admin which she is working on. She is a young person who is trying to figure all of this out and has no experience and is overwhelmed. The property is not a rental at this time, but a different family member is living in the home. She does not want the family member to pay rent, but they are taking care of other expenses and maintenance which she feels is a fair exchange. She is not living there herself at this time but in her primary home in another state.

She is wondering if she should put it into a new trust under her name.  Anyone who has experience or info that can help her, your input is greatly appreciated.  

Thanks!
