Letting go to tenant again? (9)

'letting go' is the definition.
('release' can be a synonym of 'let go')

'tenant again?' is the wordplay.
I cannot really see how this works, but
'again?' could be 're' (prefix meaning 'again') and 're' is located in the answer.
The remaining letters 'leasing' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'to' acts as a link.

Can you help me to learn more?
