Sometimes the portals will ask for proof of ownership for a property to ensure you are the owner or have the owner's permission to advertise a property.
Specifically, acceptable documentation to show you own the property is any one of the following:
- Land Registry Title
- Insurance Certificate
- Signed Letter from Solicitor (Completion Letter / Confirming Ownership)
- Mortgage Letter
You can upload this straight to your advert (it will not be visible to the public) and this can be stored on your account in case you ever need to re-advertise.
