We had this. Years before we bought our house it had flooded once. Flood defences were improved and but was classed as low risk to flood. We boughtnit no issues.
When we sold it, another 5 years later, the buyer 2 days before exchange decided they wanted money off and a further survey where they come and drill holes in the wall and other things, because no one had told them it flooded. My solicitor called me and told me. I explained that they had been round several times. I showed them round and told them myself. Because I didnt want the situation where we got an offer then the buyer dropped out because it had previously flooded.
We also bought a new build and the exchange date was the final date with the builder.
The buyers had dragged everything on so long I told my solicitor they either exchanged on the day agreed or they could piss off. No further survey, no money off. My solicitor said their solicitor had said that I should be reminded I would lose the house I was buying if they dropped out. I simply reminded my solicitor that I was not that sentimental. If I lost my new house, there would be another one. Either exchange went ahead, as planned or they could piss off.
15 minutes later I got a call saying exchange was going ahead.
On the other hand. Last year I was at the bottom of the changing and someone in the middle was stringing it out. Couldnt get life insurance, because he had to go for an assesment. Then wasnt going in to go through the contract, kept cancelling appointments.
Another exchange date was upon us. My solicitor called and said it wasnt going ahead again. I had, had enough. It had gone on 6 months. I was staying with a friends because exh had attacked me and I was sleeping on a sofa with my kids. The marital house had sold the 6 months before.
I snapped and told my solicitor, we either exchanged, or I was pulling out and would rent someone where while I looked for another property. And i would have done. I was getting fed up of dates constantly changing because one person was trying to put it off.
Again, within 15 minutes it was confirmed we were exchanging. Turned out this person was a teacher and was wanting to put off moving until summer holidays. Which I understand but up until that point they hadnt communicated that at all. If I had been told, in the beginning that I could have rented somewhere until the summer holidays. After I had put my offer in, until completion.
Some people fuck about for their own gain. Financial or to fit the timeline to them. It's like they forget that the chain is full of people with their own lives and financial responsibilities.
