Moving from rented to first time buying. Date changes causing problems
We currently live in a rented one bedroom flat and are buying our first home.
The chain for our house has 6 parties involved.
About 3 weeks ago we were told that everyone in the chain was happy with a moving date on the 13th of July, so we spoke to our landlord and estate agents who were happy to have the 14th as our move out date (which worked out perfectly as the 14th is the date of our rent payment).
We kept chasing up about ensuring that contracts could be signed so that we had a definite move out date and was told that they are going through the final part of the process and are setting up to receive our deposit.
Yesterday (1st of July) we received a call saying that someone in the chain has decided they are going on holiday, and if the whole chain doesn't agree to change the moving date to the 28th of July then he will pull out.
This has put us in an incredibly hard position, as our current place has already got someone lined up to move in when we leave, leaving us in a position where we will have to put our belongings in storage and have nowhere to live for 2 weeks.
I'm not sure what to do from here, or what I'm entitled to do in this situation, so any advice would be greatly appreciated
