Is the road busy all the time?? We live on a busyish road but it is very quiet at night so we cope. Also we got a lot more house for our money on a busier road (its only 2 lanes)
We had a hideous kitchen (all dark brown timber and a copper range hood) and we cheaply painyed the cupboards gloss white and bought new silver handles from ebay for 99c each. we replaced the range hood (also ebay) and the kitchen now looks totally different.
What is under the carpet?? Can you rip it up and have polished boards?? Would a few well placed rugs cover it until you had the money??
Hire a cleaner to come and do the bathroom before you move in.

I would buy it but thats me you need to do what you feel best about.
