Potential buyers will want to picture their car safely sheltered in your garage, alongside their landscaping tools and other items they plan on keeping there. Whether your home has a one-, two-, or three-car garage, visitors will probably fixate more on the functionality of the space than its total square footage. Here's another instance where disciplined decluttering pays off. If your garage has become a dumping ground, get rid of the junk and install budget shelving and pegboard to hold the necessities neatly. You—and everyone who attends the open houses—will be delighted by your orderly, spacious garage.
