Thanks CrankyKitten. I think we're planning to sit down and go over stuff, especially as my husband really wants to work out a solid budget. I just hope the idea of having a family isn't too far fetched! I'd be really sad if I had to wait another few years before even considering!
I think you might be surprised - without knowing your current circumstances, my suggestion would be to sit down and work out if you definitely need to move, or if you can possibly put some stuff into storage or sell it, whether you will definitely need a new car or if you can manage even with a 2-door (unless it's also a 2 seater you should be fine - I had a 2-door Barina when DD was born, I just lifted the tailgate and popped her in through the back ). Work out your max weekly rent and what sort of house you think would be reasonable for that amount - check the real estate websites for what the current market is doing for ideas here.

It's perfectly natural to feel overwhelmed with all this stuff, it's a huge change of lifestyle and a massive decision to be making - all the best
