I submitted an LOI mid-last week with a deadline of Saturday. A bit odd, yes, I'll admit. The broker comes back and says the seller's attorney needs until Monday or Tuesday. I respond with "thank you for the update, I look forward to hearing from you." It's now Tuesday and the broker is stating the attorney will hopefully have a response by the end of the week. By this point, the LOI has expired so I guess there's anything for me to do on my end. As the saying goes, time kills deals!
