If you or a loved one is considering a move or downsizing, hiring a good Appraiser and Estate Sales professional is key to making the most out of valuable possessions. A quality Appraisal or Estate Sale service will be able to maximize the value of the belongings you are parting with and attract buyers who are interested in your items. Valuable antiques and collectables may bring a higher price if the service works with brokers who specialize in your particular item. The cost to work with an Estate Sales professional generally runs between 25 and 35 percent of the total sale. Appraisal services will charge a flat fee or hourly fee for their services, they should not charge based on the value of an item.
