Locking in the Deal Before Probate in DC

[Carmen L.]

A family friend contacted me recently about a lady, who died intestate in NW Washington DC. The family is cash strapped. They are really interested in selling the decedent's very large unrenovated house. The single descendant has three living siblings and no children. One of the siblings is planning to act as personal representative, but has not filed as of yet. Is there anyway for me to tie the house up now in any sort of agreement? I contacted a RE attorney, who I have used before. He wrote:  "Until a personal representative of the estate is appointment, there is no one with authority to enter into a contract concerning the sale of the property."

One of the siblings will be calling me this week. I'm not sure what to do or say. I have scoured the forums for an answer. Any suggestions on how to proceed in the conversation as I'd like to lock this down? I'm at a lost right now, but do not want to lose what may be a really good deal. Thanks!
