7. A site that protects you from Internet fraud and spam
Look for a site that treats your details as confidential and respects your privacy.
Websites should never publish your full address. It's fine to publish the postcode or street name — this is standard practice as buyers need to know where they are looking — but avoid sites that publish your house name or number.
Also avoid sites that display your telephone number or email address for buyers to contact you directly. This can lead to unwanted cold calling from estate agents touting for business.
It's also a near guarantee that your email address will be picked up by "email address spiders" (programs that scour web pages looking for unprotected email addresses) and used by internet fraudsters and spammers.
Look for a website that allows potential buyers to email you via a link on that site and that allows you to respond in the same way. This makes it impossible for your email address to be stolen.
Once you are happy to you can then send the buyer your contact details and communicate safely using your normal email account or by phone.
Finally, look for a site that respects your privacy and which gives you a guarantee that it will not sell your email address and personal details on to third parties.
