A potential buyer for Count Dracula’s castle might also question what is tucked in the dark corners and hallways of the eerie abode.

Bram Stoker, the author of Dracula, and old Hollywood horror-movie directors understood the impact proper lighting has on a situation. A multitude of horrible, dirty, dangerous, unsightly, disgusting surprises can be lurking about, waiting for the most opportune time to make their presence known.

But while Von Helsing overcame his fears and entered the castle despite them, potential homebuyers may not make it past the unlit foyer, no matter how attractive it is. If buyers can’t SEE it, they can’t love it. Even worse, they can fear the unseen (and quite possibly insignificant) qualities, and become uneasy in a home that may be just perfect for them.

Lighting can be a relatively inexpensive but effective way to highlight the positive qualities of your home or downplay areas that are less attractive.

The most desirable and inexpensive lighting is natural sunlight. The easiest way to capitalize on this natural resource is to show your home during the daytime when the sun is shining brightly, throwing open blinds or shades, decluttering windowsills, and washing panes to allow light inside. This is also a good time to move Aunt Gerties’s antique walnut wardrobe away from the window. To do its job, light needs to enter a room unhindered.

Unless your window overlooks a neighbor’s collection of rusting cars or a grimy, graffiti-ridden wall of the building next door, it’s good to keep curtains open when showing your home. It makes the room look bigger and more inviting. If the view is less than attractive, hang sheer curtains over the window that will allow some light in while subtly distracting the buyer’s attention from the unsightly scene.

If the house is dark with few or very narrow windows, take heart. A trip to your local home improvement store can lighten things up quickly. Even naturally lit houses can benefit from the addition of appropriate electric lighting.

Begin by slowly walking through your house, taking special care to flip all switches and look at each light fixture and lamp. Are there burnt-out bulbs that need to be replaced? Keep a list of all the size bulbs you need to purchase.

Do shades or domes have dead insects or dust in them? Clean them and see how much brighter the room looks. Are there scratches, dents, dings or tarnish on fixtures? If they can’t be buffed or cleaned, consider replacing them.

If fixtures need to be replaced, consider your target buyer and the style of your house when choosing the replacements. For example, if the architecture and furnishings of your home are traditional, modern-style fixtures of polished gunmetal would look inappropriate. Or if you’re targeting younger buyers, the original circa 1970 pea green mod-style hanging lamp may need to go.

Lighting can minimize a room’s idiosyncrasies, creating optical illusions that make a room seem wider, a ceiling higher or hallway longer. Long, narrow hallways, common in today’s condominiums, can be transformed from wasted space to an art gallery with the addition of track lighting to illuminate artistic treasures. Is there a room that feels like the ceiling and floor are gradually closing in on you? By avoiding hanging fixtures and using those that throw light up a wall, such as floor can lights, one can make ceilings feel higher.

But if your ceiling has cracks or other blemishes, light that flows down to the floor moves the eye in that direction, distracting a potential buyer’s attention away from a negative feature. On the other hand, bowing walls of older houses require lighting that moves straight from floor to ceiling without hitting the wall. Here, the lamps or fixtures must be placed away from the wall and face the ceiling.

Often one can take fixtures already used in the house and move them to more appropriate areas. Life’s little horrors, real or imaginary, tend to disappear when rooms are lit properly.

Have a particularly small room? A mirrored wall will look double the size that it did when it was only painted. If the mirrored wall is across from a window, the natural light will be reflected and the room will seem brighter.

It’s important to remember that it isn’t enough to just have the proper light fixtures. You need to use them. Even during the day, lights should be on in every room of the house, including hallways, closets, bathrooms, on the stove, in the oven and under hanging cabinets. At night, be prepared for an evening buyer drive-by with lamps illuminated in rooms with windows that face the street. After all, folks need to know that Dracula isn’t lurking in the shadows.
