The Sims Bustin' Out Tips

Decorating Tip
For some reason, when decorating your rooms, I found that it costs more money to cover the floor of each room the quick way (ie pressing the preview key and then hitting x to make it cover the entire room) then it does if you do it by laying the flooring down yourself. So, instead of previewing and laying the carpet, press and hold X while laying the floor, and drag it until it covers the whole room, it saves you about half the price.

When PAINTING, it's cheaper to do exactly the opposite (But only by 20 dollars or so) so if you are tight on cash, preview the room when painting.
