Eco-friendly homes are hot these days, and one way to make a property more saleable is to add a little green.

Real estate Web site HomeGain asked about 1,000 real estate practitioners to recommend low-cost green improvements. Here are some of their suggestions:

• Plant native trees and plants
• Replace air filters
• Weather-strip and caulk doors and windows
• Install programmable thermostats
• Install low-flow showerheads
• Install CFL or LED lights
• Repaint with low VOC (volatile organic compound) paint
