We sold our house about 2 months ago and found a house to buy a few weeks later. There's been some delays with the chain but it's moving again and we hope to exchange in about a month then complete end July / early August. The dc are 9 and 6. When is the best time to take them to see the new house. I wasn't planning until exchange in case it fell through but I'm not sure if we should make it sooner?
