Properties are often sold during the probate process. If the estate is subject to the Independent Administration of Estates Act (IAEA), there may be no court confirmation required -- otherwise, there will need to be a hearing where a judge will approve the purchase price (and solicit overbids -- yikes!). Another thing to consider is that the disclosure requirements for a property sold in probate are quite different than a traditional sale; the sellers are not subject to the same disclosure requirements as a traditional seller.
I would suggest speaking to a REALTOR who has prior experience with buying and/or selling probate properties, as they will be better equipped to help you navigate this unfamiliar terrain. A local estate planning attorney should be able to provide a good referral. I would be happy to provide one in your area as well if you like.
