After weeks of harassment from our sellers about the process going too slowly (it's been about 5/6 months due to us losing one set of buyers halfway through - we've been chasing solicitors like crazy trying to speed everything up) we were due to exchange yesterday. On the day however, we received a message via the vendors' solicitor saying that house prices had gone up so much in the time it had taken the deal to go through that they wanted an extra £33k (they gave a whole bunch of other vague reasons too, which I think boil down to they've had to pay for an extra term's private school fees?!!) Obviously we don't have this money and even if we did we don't want to give in to such horrible tactics. The vendors aren't in a chain going up - I don't know where they're moving after this.
The house had been on the market for a while when we made our offer and had been reduced twice. I believe we were the only offer (it has potential but needs quite a lot of work). We offered £8k under the lowest asking price. At the time there was plenty on the market in the area and now there is nothing we could afford. All the houses available are bigger and nicely finished, which does give the impression prices have gone up, but I think it's a bit misleading.
We are financially stretched to our limit as it is but are in a flat with a baby and desperately need more space. We've spent so much time and energy (and money) on this move and we're just exhausted and depressed by it all. My family want us to walk away and not give any money to such horrible sellers. What would you do?
