Best refinancing Strategy
You should speak with lenders or a broker about this deal. I would start with the current lender.
A lot depends on what happened with your bankruptcy, your current financial position, and the asset itself. It's not clear what type of asset you have from your post. You mention it's a commercial asset and that you rent out some units as a vacation rental. Since you are not cashing out and looking at a low leverage deal I would think you should be able to refi this.
Agree with @Eric Schleif, you should be able to refi. Low leverage and good NOI. Banks and traditional lenders will likely balk, but there are alternative lenders who will look past your BK. The vacation rental aspect is interesting...as that sounds more like lodging than multifamily.
