I should have added I really like Miss E's suggestion too. But I hate paying rent.

TBH, the more I think about it, the more I'd probably do it sooner rather than later. DH and I have talked about moving into his parent's house if they ever did a big trip like yours are doing... and I reckon if we planned that, I'd be keen to get in there as soon as we were able, to start saving money.

Financially - will you be better off if you go sooner?
