No. Not until you have further investigated the nature of the lien, and the state of affairs for the owner's Estate. If the debt secured by the lien is not paid out of Estate assets, the lien will follow you, and you could lose the home because of the lien. The lien might even exceed the value of the house. And you are describing a very expensive series of transactions, especially if you are not a blood relative or heir. There is nothing attractive about what you are describing. But a lawyer migh help you make this into something that you can live with, depending on what is going on with the Estate.
I was originally going to say NO - but upon further reflection, my answer is that it depends.
It is my understanding that you are being offered ownership of the home (at no cost), that the home has a lien on it, and that you want to flip it. Thus, it becomes a cost benefit analysis: What is the value of the home versus what is the amount of the lien? If the home has sufficient equity, then you could sell it, pay the lien and earn some money. If the home has little or no value, then don't take on the headache and the responsibility of having to pay taxes, etc. if the home does not sell.
Before doing anything, you should have a title search and judgment search performed to ensure that there are no other liens, unpaid property and estate taxes, etc, that might reduce the equity in the home.
I am not a MD attorney, laws vary from state to state, therefore you should always consult a local attorney.
