Looking for some advice...
We had an offer accepted on a house, the vendors (who we had never met) were willing to go into rented. We could not get completion dates to line up so we completed on our sale and moved into rented. It’s ok but far from ideal, some stuff unpacked but most not, too small , only bbc1 and bbc2, and cbbc 
Our offer was Made beg of Aug, we had always been working on a timescale of mid Oct but this was not confirmed. Found out today that buyers have not found a suitable property to rent - they were looking at somewhere else this eve though. There is talk of them being willing to go into an Airbnb, they have given away much of their furniture as they are downsizing.
I’m really hacked off. They’re dragging their feet. We sorted our rental and put ourselves out so we didn’t jeapordise our sale but they are not doing the same. I ranted at their EA today and expressed my unhappiness, I vaguely talked about looking at other properties. Their EA indicated to my DH that the vendor is a very difficult man. They want to move ... but at their timescale.
I want this house. Not many in this area that we really want to be in. But god, I need the vendors to be a bit proactive.
What can we do? We’ve not exchanged yet,
I’m scared to threaten to pull out if completeon is not done by a certain date, what if they call our bluff? Can we reduce our offer and link to a completion date?
Would really appreciated some advice
