House sales that are part of an estate are more complicated than a normal sale. They can be relatively easy, assuming you go through the proper channels. Unfortunately, an interested buyer cannot file for probate. Only the heirs of the owner may file for probate. I wonder if this house was in a trust - that may be why no probate was filed. If you do find an heir, you will want to have a real estate agent or an attorney assist you with the purchase process. Once you have a contract with the heir, the court must approve the sale if the home is in probate. If there is a trust then there is no probate and title should first be transferred to the heir(s) and then the sale can proceed. Please make sure you obtain title insurnace (typically the seller pays the buyer's owner's policy, the buyer pays the lender's policy). You should consult an attorney regarding your particular situation but I hope this gives you an idea of the process.
