How likely will my house be sold at auction?

This is a NON-judicial foreclosure... I have not received a sale date yet. The mortgage company bought my loan from my original lender, the original lender is still in business. Value of the house is $300,000 (used chase.com for comparables - they are the most reliable I heard). I am underwater on my house by $140,000. I have $150,000 in liens against my house. I would like to stay in my house for as long as possible, until I find myself a job, and then I should be able to re-negotiate with my mortgage company. How likely is this house going to be sold at auction?
