It often makes more financial sense to buy new stuff when you have the chance to sell furniture to offset the cost. The cost of moving your current furniture can sometimes be more than buying new things, particularly if the furniture is large or cumbersome to move. You can sell furniture online, or make a furniture donation and deduct it from your taxes (if it qualifies as a charitable contribution). Some places near you may even offer free furniture pickup when you choose to donate.
If you have valuable furniture that would be costly to replace, however, it may be cheaper to move them. To find out which option is best for you, contact professional movers in your area to receive quotes and estimates.
