I was very lucky to buy a 2 bed flat when I was 25 (nearly 10 years ago). I just love it and I'll be honest, I am reluctant to leave it.
DP wants us to have 'our' place rather than my place. We're getting married in April (relatively small wedding but still a bloody fortune) and then we're going to TTC immediately (esp because of age). I am conscious of trying to save for all of this and house prices are so, so high. I think we should stay put for another 2/3 years but he seems to find it so important that we have a family house.
