A potential homebuyer needs to picture herself in your rooms, and quirky decorating or pictures of the kids hurts the illusion. Remove all family and, if necessary, paint brightly coloured walls with a more neutral shade.
2. Make sure everything in your home is in top condition.
No torn screens, cracked plaster or burnt out pot lights. You may have gotten used to seeing them, so tour your house with a critical eye (or ask someone else to), and repair anything that needs it.
One of the best low-cost, high-return investments is proper lighting. People think you have to spend a fortune on lighting, but you can go to any big box store and get beautiful ones for, at most, a few hundred dollars. Many houses don't have enough lighting to begin with, so if you're having the electrician in anyway, have more overhead fixtures installed -- or at least buy some great lamps.
4. Be aware of scale in the house when it comes to furnishings.
You might have a giant sofa that you love, but if it makes the room look small, it has to go. Aim for small groupings of furniture (ideally more than one in a room, especially a large one), with plenty of space around them.
5. A clean kitchen.
Kitchen counters should be clear and clutter-free. A single bowl or vase holding cooking utensils is okay, but that's about it. Store small appliances in cupboards if you must.
