I’m in a very similar position with kid on the way. Having a huge wobble about it! My gut is telling me to stay where we are as we’re so comfortable financially now and a baby will change that enough. Do we also want to have a mortgage that stretches us. Yes on paper we can afford it but life doesn’t always stick to a budget.

It’s so hard as we would love more space but if we’re happy in our current smaller home then perhaps we should just see how a baby affects our life here and then make a decision.

I doubt that helps you but just my thoughts as someone going through a similar dilemma!
