Yes but my point was a small delay doesn't automatically mean lack of motivation, sometimes it is just logistics
Also I do think you are getting concerned way too early. If sellers only received revised paperwork yesterday, 24 hours is way too quick to have any concerns. My buyers took 5 days to return contract.
I understand it is an emotive purchase for you but for sellers often it is just one more thing on the to do list. Trying to give you a perspective on how sellers feel. I am selling a small contract because I added on at another resort so I no longer need it. I don't have to sell, I could have kept it I just don't need it. When it sells the money will just be going into our savings. so for me signing the paperwork is just another thing I have to do like laundry and cleaning the bathroom. That doesn't mean it doesn't get done it just isn't as prominent in my mind as your purchase will be in yours.
