As the other agents have said this could get messy. It is possible that there could be liens against the property that are more than the current value of the house.
You should definitely contact a real estate attorney for advice in this matter.

If the deed to the property was in the names of two or more people, then ownership typically will go to the others on the deed. So if the deceased was previously married, and the ex-spouse's name was on the deed, then the ex-spouse might well become the owner.
Different states have different laws on how property gets transferred, and to whom. For example, in some states, if a person dies without a will (it's called intestate), the property passes to the spouse. If the person is unmarried, it might pass to the children. However, you say the "deceased was not married at the time." If the deceased was previously married, then the ex-spouse might possibly be able to assert some claim to the property, whether or not that ex-spouse is on the deed. Again, that's a state issue, and things can get very, very complicated.
All this assumes that the property was not in a trust. If the property was in a trust, then the trust documents (and not the will) will determine who ends up with the property.
And if it wasn't in a trust, if it was in the deceased's name, you still may not be able to obtain the deed. It becomes part of the assets of the estate. Let's say the property is worth $100,000. And let's say the deceased had bills and debts of $50,000. Most likely, a court would direct that the property be sold, the debts paid off, and the remainder divided among the heirs, as determined by the state law.
It can get very messy. That's why you definitely need an estate or probate attorney.
Hope that helps.
