Well the loan is secured by the Columbus home so it should not affect your current home whatsoever. The impact to you would be mainly financial and credit-related, I think.
Since the C'bus home is no longer your primary residence, I don't know that you'd be afforded the same protections from liability as someone who faced losing their primary home.
You may want to reach out to a HUD approved housing counselor to see if they have any recommendations. They may even be able to help you negotiate an arrangement with your bank. An attorney can also provide you advice on this, albeit at probably a higher cost.
If you're not concerned about your credit then you could always pursue a short sale or just let the home go to foreclosure. But those actions are going to severely impact your credit.
I hope this helps somewhat!
