Rent a Dumpster
"People chronically underestimate just how much trash is in their garage," says Walsh (for example, Allison had originally thought the unwanted contents would fit in just a few borrowed trash cans). "For not very much money—usually about $200 to $400—you can get a ten-yard Dumpster delivered and picked up, which is so worth it." Google "Dumpster rental" and the name of the city nearest you to compare prices. If you really don't think you can fill the whole thing, share the cost with a neighbor.
