Hi, it is supposed to be a very short chain of 3 with me at the bottom, my seller and the developer the seller is buying his new house from. My offer was accepted mid July. Mortgage approved end of July and I got everything ready on my side. Having being told that completion should be mid Sep and after 10 weeks of very slow progress, the seller now came back and wants me to exchange with "completion on notice", because the developer wants that. I know that it is not unusual that a developer would ask for "completion on notice", i.e. while we are contractually tied, the developer can take as much as time it wants to complete. What annoys me is that, normally my seller should be the one to break the chain, but he is trying to pass all the risk to me by getting me signed up for "completion on notice" as well, because he cannot afford the rent to break the chain. What should I do? Refuse to exchange? The EA says in that case, the developer will treat my seller as "unproceedable" and remarket the property and the chain will collapse. I already spend over a thousand pounds on survey and solicitor. I also feel a bit angry, because I think the seller and the developer have been lying to me, because they knew if they told me the truth, I would not have made the offer nor started conveyance.
