I would start with a new listing at a new price. I just had one that was off the market for a while and we (as new agent) came in and listed at a higher price because the market has really picked up and I had the seller do some additional staging, and it sold in one day. Start with a fresh listing with new pictures (maybe proper staging if it wasn't already).
I'm quite sure I understand about paying it off and selling to your husband. Are you getting separating or what's that situation? If you are going to pay it off, you can just go ahead and rent it as there wouldn't be a large debt, so it shouldn't affect you getting a new house and mortgage. They're just looking at total debt. You can own more than one property.
Another option is checking to see if you refinance your current home, will you (and your husband?) maybe qualify for 2 homes? Many people do. Then you can rent it even with the mortgage.
Just a few options. Best of luck to you.
