What exactly do you mean by closing out an estate? Is this for purposes of transferring title to you? Or, are looking to sell the property? Depending on your answer and the scenario, will dictate what needs to be done. If you would like direction on the estate, feel free to contact me and I would be happy to assist in any way I can.
The short answer is any title co in the area can do the search. We use Chicago title for the search and Landmark or Sonnenberger for surveys.
