According to Wikipedia, Feng shui is an ancient Chinese system of aesthetics believed to utilize the Laws of both heaven (astronomy) and earth (geography) to help one improve life by receiving positive Qi. (Qi loosely translated to air). 

To put the best face on a listing and appeal to buyers who follow feng shui principles, keep these tips in mind.

1. Pay special attention to the front door, which is considered the “mouth of chi” (chi is the “life force” of all things) and one of the most powerful aspects of the entire property. Abundance, blessings, opportunities, and good fortune enter through the front door. It’s also the first impression buyers have of how well the sellers have taken care of the rest of the property. Make sure the area around the front door is swept clean, free of cobwebs and clutter. Make sure all lighting is straight and properly hung. Better yet, light the path leading up to the front door to create an inviting atmosphere.

2. Chi energy can be flushed away wherever there are drains in the home. To keep the good forces of a home in, always keep the toilet seats down and close the doors to bathrooms.

3. The master bed should be in a place of honor, power, and protection, which is farthest from and facing toward the entryway of the room. It’s even better if you can place the bed diagonally in the farthest corner. Paint the room in colors that promote serenity, relaxation, and romance, such as soft tones of green, blue, and lavender.

4. The dining room symbolizes the energy and power of family togetherness. Make sure the table is clear and uncluttered during showings. Use an attractive tablecloth to enhance the look of the table while also softening sharp corners.

5. The windows are considered to be the eyes of the home. Getting the windows professionally cleaned will make the home sparkle and ensure that the view will be optimally displayed.
