To ensure potential buyers get a good first impression, consider small touches such as a new mailbox or front mat, or maybe go for a more expensive upgrade with a new front door. Tania Matthews, a real estate agent with Keller Williams Classic Realty III in Clermont, Florida, says front entrances should be kept clean and, if needed, pressure-washed to remove grime. "You'd be surprised how much it makes a difference," she says. Depending on the neighborhood, a mowed lawn, trimmed bushes, or well-kept rock garden can go a long way. Topping off potted plants or a garden with fresh mulch or soil is another good and inexpensive idea.
