Soldato
Know of a couple of instances one with a colleague and the other my previous neighbour where someone in the chain decided to drop off the face of the earth mid sale and expect everyone to wait on them - in one case they'd gone on holiday to the south of France for 5-6 weeks or something and were surprised when they came back to find they'd lost the sale/purchase.
House moves are up there with my least favourite things - I'm not sure our last one would have even gone through if it wasn't for the estate agent was so pushy with the solicitors (I find it strange to credit an estate agent).
Just had that with my youngest buying her first home. Sellers already had another house, so took their sweet time completing paperwork and responding to anything. Apparently both my youngest’s and the seller’s solicitor were totally ****** off with the vendors for making a super easy no-chain sale very hard work.
