am about to be laid off

I have a condo in IL, I bought the unit in SEPT/2008 for $309,000, one week before the economy collapsed. I put all of my savings into the purchase, and took out a 2nd, smaller mortgage. Now I am totally underwater in the property. My current primary mortgage is $235,000, the secondary is $24,000. I have been saving to pay off the second and will be able to do so next month. I am current on both primary and secondary mortgages, but struggling considerably as my property taxes go up 20% per year. A recent sale in my 3-unit building went for $200,000. If I sell it on my own, I will still owe on my primary mortgage. As if that wasn't enough, I have been notified that I'm about to lose my job, probably in the next 4 months. What are my options, i.e., is a DIL better than a short sale? Lastly, once I lose my condo, I will have nowhere to live. Are there any options to help people like me. I am on my own, sole source of support.
