 Updates like gray laminate floors, barn doors, and subway tile are cheap fixes to make a space feel more modern. But since not a lot of new housing is being built, the bones of your new home could still be old. Some landlords and house flippers cut corners and chasing profits, and this can lead to some major problems. It's cheap and easy to replace a regular door with a barn door, but it's time consuming and expensive to rewire a house, or to put a new roof on, or to install a new heating and cooling system. So if you're buying a house, you should never waive an inspection. And if you're renting, be sure to inspect the space with your landlord before you sign your lease.
