I am trying to get my head around how this works, logistically. We were renting before we bought our current house, so although the people we bought from had a chain, there wasn't one for us, so we just had to wait for all those in the chain above us to sort themselves out.
We have an almost 2 year old DS now, and we need to find somewhere bigger (in the same area). We can put our house on the market and then someone may offer to buy it, but what if there isn't a house on the market that's suitable for us to buy when that happens? Presumably, a potential buyer of our house won't be prepared to wait indefinitely for a completion date.
Similarly, is it acceptable to make an offer on a house if yours is on the market but you haven't sold it yet?
