We viewed a house about 6 weeks ago. Loved it. Had a second viewing and wanted to make an offer. Spoke to seller, explaining we were awaiting an offer on our house first but we had someone who had seen it 3 times and was apparently "just waiting for her husband to return from his business trip on Friday" and then would offer on ours. Well unsurprisingly she then went radio silence. I was in touch with sellers EA regularly letting them know we wanted it but still weren't in a proceedable (?) position. Even put forward a full asking price offer if they'd hold on for us. They didn't want to wait. Fair enough. Well this morning I looked on RM and it says it's SSTC. It wasn't on Friday. Thing is we've literally (like 2 hours ago) accepted an offer on ours so now we ARE proceedable. We are considering getting in touch and offering them £750k - asking price was £735. What do you think? Is this too immoral? Would you do it?
