It''s always good to consult a solicitor as soon as possible. Many do a free initial consultation and this should be a simple matter that can easily be covered in the free half hour. You don''t necessarily need to take them on if the fees don''t justify the results, but you can get loads of good advice.
There''s probably not much point informing you of every viewing, since you left 3 years ago. But you should be consulted on offers, or give some indication of what offers you are prepared to accept.
