I think to be more practical you need to think ahead of the finances... new house needs renovation, that will have cost too.

My best advice, you need to be honest with your future wife about the finance and what to do moving forward : the house, furnitures, wedding preps, so that both of you will make the most and happy about the process. If not done well, it's not gonna be smooth post day 1 of marriage.

I just recently got married after being with her 7 years. Things shouldnt be in a rush especially if you are cash tight. You should think carefully what's best. Delaying another 12 months to get finances in order is not a bad thing to do either.
