A new trend for homeowners is fall cleaning together with yard sales and garage sales. Today, in Part 1, selling stuff, you'll learn presentation and planning helps you earn the most possible. It's important to start early. Amateurs wait until the day before to start planning for garage sales; pros start weeks, even months, ahead. Give every aspect of your home and lives a thorough review. Ask "Do we need this or still want this?" Then create a collection area in the attic, basement or garage where things are sorted. Sort things as follows: "good condition," "sell as is," "needs cleanup or repair," and "giveaways." Group thing on tables for easy viewing and price them, so that asking isn't necessary. Helpful selling aids include a tape measure and a live extension cord to prove things work. Have plenty of change on hand and bags, boxes and newspaper to wrap things. Tomorrow in part 2, buying stuff, you'll learn an early start and preplanning helps. And that's the On The House Tip for today.
