In the interests of fairness if you include the rent on the garage, parking etc that you hand't been charging for previously that does raise it to 67.5% rent increase. and in the interests of fairness, you (or rather your surveyor) have singularly failed to answer emails or process the responses from the Toy Shop at all. Thus failing in your duty as a landlord to actually you know, manage the property. Add that to the fact you have three pubs, none of which are currently opened (in fact one has been demolished) and your inabiliy to curate the mix of shops so that there is a good mix of shops ( I believe that Number 22 has been let to a hairdressers, the 7th in the area not counting barbers - I refuse to believe Herne Hillers have that much hair) then I'd argue you do have a case to answer for not performing your duties as a landlord adequately
