Screening potential buyers before you permit them to view your property is a great idea and less complicated than you would think.
Selling your home could mean you may end up showing around someone you do not know. We suggest that you ask for the full details for anyone who wants to view your home, if they are not prepared to tell you their full names address and contact details including email and phone numbers then are they really serious?

We suggest that before any viewings are arranged a two way dialogue has been achieved and you should feel comfortable about the viewing. If you are a single person why not invite a neighbour or friend around whilst the viewing takes place. For more on this subject please take a look at this page on the Suzie Lamplugh Trust website
