There are several considerations to regain title to property held by a deceased. If the property was not left to you in a Will or by Deed as a remanderment you should seriously speak with a real estate attorney who specializes in real estate. As a real estate paralegal in my previous career, I know several real estate attorneys I could recommend to you. If you still need assistance with this, please call me at 954-501-3668.

Let me say that you should seek legal guidance on this.
If there is equity in the house, the Estate will sell the house and pay you off for your mortgage. You did record your mortgage, I hope! If not, immediately go get an attorney!
If there is no equity in the house, you may be able to contact the Personal Representative/Executor (or her attorney) for the Estate of the Deceased and they may just simply quit claim it back to you. They may need court approval to sell the house or quit claim it back to you, though..
So bottom line you need a Real Estate attorney to help you. You might want to contact the attorney that wrote your mortgage and/or the title company that recorded your mortgage.
All the best,
