Renovating a home in the hopes that it will sell quickly and for a profit doesn't have to be a costly, time-consuming process. In fact, just a few simple add-ons can make a significant difference. CNBC Make It sat down with real estate mogul Sidney Torres, who helps struggling property investors on CNBC's "The Deed," and asked about affordable features that can add value to your home. Here are three details he says are worth investing in.

1. Dimmer switches

Dimmer switches let you adjust the light levels in a room by sliding a level or turning a knob. They're an affordable way to "create a nice ambiance," says Torres, since they can "really set the mood and the space." He likes to install dimmers in "all the different rooms that you live in a lot, for example, the kitchen area, the living room area, the bedroom, even bathrooms." Cost: According to HomeAdvisor, dimmer switches average $10 to $25 each but can cost up to $50 depending on the style you choose. Since you'll probably be installing multiple dimmers, the project typically ranges from $100 to $200.

2. Under-cabinet lighting

Under-cabinet lighting is as simple as it sounds: A strip of lighting that runs underneath your cabinets. But the benefits can significantly boost the value of your home, says Torres, who likes to include this feature in the kitchen. And it's easy on the budget, says the real estate veteran: "It's not expensive to do, but it's nice. It washes down the backsplash. You can also put them above the cabinets, which is nice too. If you have nice crown molding, it features the crown molding." Plus, under-cabinet lighting adds depth to your kitchen: "It gives the ceiling height and makes it feel higher than what it really is." It may even save you money on your energy bill. Cost: The total cost will depend on how many fixtures you want to install but expect to pay $230 to $330 per fixture if you're hiring a professional, ImproveNet estimates.
