We bought a house significantly more than we intended initially, because overall it was much better value (much bigger, never need to move, free flooring, turf, fencing, tiling etc) which meant we had zero savings.
Then used 0% credit cards to furnish the whole house.
That was 1.5 years ago, and we will be credit card debt free next month.
Don't regret it, would do the same in a heartbeat.
I think you should buy the best house you can afford, and we did. Paying it back was easy because we had the house of our dreams.
Ours is a new build and I agree with a PP that says there are no unexpected bills for a long time.
However I am in the public sector so secure employment.
