My SIL sold last year, and the best piece of advice she got and she followed was fix the house up to showhouse standard. Every ding in the wall got sanded and filled. completed paint job. Flooring got repaired. Huge amount of stuff in storage, great tip was to half empty the cupboards as it makes it look like there is more storage, and all personal stuff removed. She spent $5000, got close to $20,000 over asking price and it sold within a week of being on the market, and this was in a suburb not hugrly sought after.
