In escrow with preliminary Title, seller received letter of lien

[Julia Fergo]

In escrow 15 days by now, towards 45 days close escrow. The property is in LA where I live,  the real estate agent represents both seller and buyer. I am done with inspection and forwarded request for repairs to the seller.This morning the agent calls me and informs that the seller received a letter about a lien from the lender and nobody knew about it. The house is in Trust on sellers mother name and the mother just passed away a month ago, and this why the house is for sale. the agent also complained about the reverse mortgage that somehow could be the reason for the lien...  she said it would take few days to figure what is going on. My question is what is a possible scenario? Also - could it be a way out of escrow because the agent mentioned there are 3 back up offers the property received already, my be more and here I am asking for repairs...:).
