We bought a house in January and got married in March.
Plan. Don't put anything on credit if possible. Don't try to plan an outlandish wedding. We put stuff on credit because we intended to pay it completely off when tax time came around the next year, but by that time we had new bills and we weren't able to COMPLETELY pay it off so beware. I would see what I was able to get from tax refunds, bonuses for work, school refund checks, and etc and plan around that.
Your house won't be completely furnished and that's okay. You will get plenty from gifts from the wedding. We were able to buy a new living room set that way. We had all our old apartment furniture for a lil while after moving into the house. Piece by Piece we craigslisted and Miskelly'ed our way to new stuff.
