Well OK you re the fella with the garages -
I use: Guide to letting property - Sproston - ISBN 1-900694 - 05 - 0
I think that is the short no
and
Landlord and Tenant - Wilkie and Cole - ISBN 0 333 79428 - 1
Your own problemm is pretty specialised
and I think, considering you have a batch it may be worth paying for advice on the first case
however
I think you should assume your lease is short hold assured
issue a s21 notice requiring possession
and accept you have to get a court order
your real problem is to get the tenant out
and really not anythinng else
its not really property law but landlord and tenant
which is why you cant access books to your taste
For Property - I recommend Gray - Landlaw
only because he was a bright fella in my year in 1973
big book lots of pages, and yo will come out the other side knowing an awful lot about Land Law which you wont find much use.
