When you're renting and the pipes burst, you can call your landlord, and a maintenance person will come out to fix it. As a homeowner, you're your own landlord, and all of those little hiccups become your problem. It's your responsibility to maintain the lawn, fix things that break (or pay a handyman) and keep up with aesthetic maintenance, like painting the porch and shoveling the driveway when it snows.
Are you ready to take on the time and expense involved in maintaining a home? If you're not prepared to care for your property, it might not be time to buy a house.
