1. Ask management if you can post or distribute fliers before doing so.
2. Show the landlord a flier then ask him or her if she can make it available to visitors who come to the office.
3. Post flier on a public board i.e.) laundry facility, library, coffee shop, community center, church, etc.
4. Create an online ad i.e.) Craigslist, Bookeo, and eBay for starters.
5. Upload photos on a social networking or photo sharing site with contact information i.e.) Facebook, Instagram, and Twitter.
6. Call local newspaper to advertise your service i.e.) Pennysaver.
7. Use word of mouth, tell neighbors, family and friends about what you are selling or giving away. Have photos or fliers handy.
8. Don't set up a table, sell from garage, or leave things out in the community unless you have permission from the landlord or owner.
Once you have an interested prospect, arrange to meet he or she on a day that isn't busy in your community especially if he or she needs a truck to come pick up the item. Be sure you advise the buyer not to park in any reserved parking spot or block someone's garage. Remind the individual to bring a tool to help with moving the equipment or an additional set of hands. The last thing you want to do is make a lot of noise or damage walls or stairs by dragging or banging something.
By taking the necessary steps to rid yourself of whatever you don't want, while hopefully making some money, you won't run the risk of being a problem for your landlord and neighbors.
