'check on homes' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'check on homes' is the wordplay.
'check' becomes 'rein' (both can mean to control or limit).
'on homes' becomes 'in' (I can't justify this - if you can you should give a lot more credence to this answer).
'rein'+'in'='REININ'
