Legal Question in Real Estate Law in Georgia

Your first sentence is not necessarily true, and you have not posted enough to begin to answer you. See a lawyer.

To begin with that statement is incorrect. In Georgia if one parent dies intestate (without a will) the remaining property will go to the heirs per stirpes. If there is a surviving spouse and 1 or more children they will divide the property but the surviving spouse will always receive at least 1/3rd. So the interests vary based on the surviving heirs the surviving spouse will always have at least 1/3rd.

The property at the creation of a probate estate would vest in the administrator of the estate, but would have to be given a power of sale. Most closing attorneys would require quitclaim deeds from the heirs at the time of closing and probable affidavits of descent. The heirs would need to be notified as to the sale of the property.

I have no idea what you mean by "can the potential buyer obtain the property with no ownership rights other than the contract." I guess I don't understand it but my answer is an uncatagorical "no."
