Put our house on market in mid Oct for 325000. Had viewings but no offers. Took off in Dec and then reduced price to 325000 mid Jan when we put it back on. Again had lots of viewings. We have just relieved our first offer. It's full asking price because they haven't sold their house yet. It's not even on the market. They are offering full asking price on condition that my estate agent sells theirs (it's about an hour's drive away). They are selling for 670k. I'm worried that A. We take ours off the market and they don't sell. B. That they will join a chain and we are likely to too. C. This will all be over the Brexit negotiations ( which I suppose is true of any offer). Any advice? Thanks in advance.
