No you don't have to transfer the deed. Usually the heir, or another relative, will be named administrator (or Executor) for the Estate of...(the deceased) and the property can be sold by the Estate. The heir will then pay inheritance taxes upon sale before the proceeds are distributed to heirs. If the deceased parent lived in Philadelphia, you can go to the Register of Wills office in City Hall and they are very helpful walking heirs through the process to probate the Estate.
Hope that helps. Please feel free to call me with any other questions.
All the best,

I hope all goes well!!
As to transferring the title before selling, it may not be necessary, nor the best course of action. If it is necessary to transfer the title before selling, be sure to contact a title company or an attorney who will check for any unpaid liens or mortgages. Hiers often make the mistake of transferring the the deed themselves, only to find out later that they have become responsible for mortgages, taxes and other unpaid liens.
