Selling w/a Lien

[Sarah Grise]

Hi all! So my husband and have been throwing the idea around of upgrading to a larger home, conveniently located across the street from where we are now. The not so good news is that we have a lien on our house. We took out a $50k Home Equity Line of Credit in which we purchased 2 investment properties with. We've been making our payments on time every month for the past 2+ yrs but I know this will be a major disadvantage should we sell. 

Wondering if there are any ways out there to have a bank pay off the HELOC for us and then we pay that bank back...? Any other options?

Thanks in advance!
