How to buy second-hand safely from private sellers

Marketplaces and classified ads connect you with private sellers who are, overwhelmingly, just people clearing out a cupboard. But private sales come with fewer protections than buying from a shop: in many places the item is sold “as seen”, there is no returns policy, and if the seller disappears there is nobody to complain to. That makes the research you do before paying especially important.

Research the seller

On platforms with profiles and ratings, look at how long the account has existed, what else it has sold, and what buyers have said. A brand-new profile is not automatically suspicious — everyone starts somewhere — but a new profile selling a high-demand item cheaply deserves extra caution. Look at the photos: do they look like the seller’s own home, or like stock images and screenshots from other listings? A reverse image search can show whether the pictures have been lifted from elsewhere.

Keep all communication on the platform. Sellers who push to move to text, email or another messaging app are often trying to get you away from the platform’s monitoring and buyer protection.

Research the item

• Price check. Look at completed or sold listings for the same model to see what it really goes for. A price far below that is the lure in many scams.
• Serial numbers. Ask for a photo of the serial number or model label before you travel. For bikes, search stolen-bike registries (such as Bike Index in the US or BikeRegister in the UK). For phones, the IMEI number can be checked against blocklists of phones reported lost or stolen; in the US, the industry body CTIA runs a free stolen phone checker.
• Recalls. Look up the model on the relevant recall list, especially for baby gear, toys, heaters and anything with a battery. Our guide to checking product recalls lists where.
• Activation locks. Phones, tablets, laptops and smartwatches can be tied to the previous owner’s account. Ask the seller to sign out and reset the device in front of you, and confirm it reaches the setup screen without asking for someone else’s login.

Know the common scams

Meet safely and inspect properly

Meet in a busy, well-lit public place during the day. Many police stations in the US and UK are happy for their lobbies or car parks to be used for exchanges, and some have designated safe-exchange zones. Bring someone with you for anything valuable, and tell someone else where you are going. For large items that must be collected from a home, go with a friend.

Take your time inspecting. Plug it in, switch it on, check every function you care about, and compare the serial number with the photo you were sent. Bring what you need to test it — a charger, headphones, a tyre pump. A genuine seller expects this; someone who hurries you along or refuses a basic test is giving you information.

Pay in a way that matches the risk

For in-person collection, cash or an instant bank payment made once you have inspected the item is common and reasonable, because you only pay when the item is in your hands. For anything posted, use the platform’s own checkout if it offers buyer protection, or a payment service’s purchase protection option. Avoid “friends and family” payment options for purchases from strangers: they are designed for sending money to people you know and usually carry no buyer protection. Never pay with gift cards or cryptocurrency. See the safest ways to pay for a comparison.

Get it in writing

Ask the seller for a simple written receipt, or send a message through the platform confirming the item, serial number, price and date. It costs nothing, it gives you a record if the item turns out to be stolen or misdescribed, and a legitimate seller will not mind.
