Many developers experienced in quickly flipping property will advise a novice not to get too attached to a house, and to leave their personal interior taste to their own home. They will say you shouldn't end up having too much heart and not enough head in the project.
It should be more about buying at the right price, doing the necessary work in good time, decorating to appeal to the majority of buyers and moving it on as quickly as possible at the highest price possible, to release your profit, and move on to the next one.
Not many, if any, would suggest you get so attached to an abode that you upgrade it to your personal taste, to higher standards than the price bracket may warrant, and fall in love and move yourself in.
