Curb Appeal on Point - Make sure toys are picked up, lawn is mowed and the driveway is clear.
Show the Home You Listed - After the pictures are taken, people expect to see the home you listed. Don't make any major changes in the decor of your home unless you take new pictures.
Keep it Clean - Keep out clutter, personal items and dust and vacuum as necessary.
Address Any Odors - Whether it's pet or cooking odors, keep your home smelling like NOTHING as much as you can.
Comfortable Climate - Even if you like it cooler or warmer, keep your home at a comfortable climate (around 70 degrees or so) while it is being shown.
Let There Be Light - Make sure you have plenty of light in your home. Change out any bulbs that take a minute to brighten. You want as much light in your home as possible.
Pay Attention to Pets - Either take your pets with you when your home is being shown, or be sure to notify those who are coming that there is a pet in the home. Also, if they are in a cage, be sure the cage is cleaned as well.
