A foreclosure house with open probate case in Texas

[Chad Coleman]

I am wondering what are the risks in this case? the previous owner passed away 6 month ago and the house is currently vacant.  The probate case type which is open letter of independent administration was opened two weeks prior to the sale. The auction sale value is more than what the persons owe.  There is barely any equity on the house and possibility the deceased person started to fall behind payments. Not sure what are the risks, I have read that the sale could be voided or it will be valid but I won't be able to get title insurance if I decided to sell the house! The house has furniture and a car in the garage, at this point, I am not planning to touch anything in the house until I figure out what is the exact situation.  Please advice with what course of action that I need to take, I am not sure who is the person that putting the probate case, it seems to be not first degree family member. thanks in advance for help
