Tenant going round back of house to get in again (2-5)
I believe the answer is:
re-enter
'get in again' is the definition.
'tenant going round back of house' is the wordplay.
'tenant' becomes 'renter' (synonyms).
'going round' indicates putting letters inside.
'back of' suggests the final letters.
The final letter of 'house' is 'e'.
'renter' placed around 'e' is 'RE-ENTER'.
'to' acts as a link.
(Other definitions for re-enter that I've seen before include "Come or go in again" , "compete again" , "Go back in" , "Come back inside" .)
