Yes, you can. But, I don't like working with Sale By owner deals during the foreclosure process. There are a lot of times my clients get overwhelmed with their circumstance surrounding the foreclosure process. I understand why that occurs, but having my client list their own property by owner requires me to rely on my client to do one of the major components of their own sale. Which is to sell the asset and get a decent contract.
The owner of FSBO.com sold his home using a Realtor as he couldn't get the price he wanted.  So, if you are trying to save on a commission trying to do it yourself, you may discover the only people calling you are realtors trying to get your listing an investors trying to give you 80% of what your home is worth.
You also need to be wary of people trying to assign your property. An assignment works when one person gets you under contract for say $200,000 and then sells it to someone else for $250,000 pocketing the $50,000 in equity that could have been yours if you could have contacted the person offering $250,000 directly.
