Number reconsidered as nice occupations (9)

I believe the answer is:

tenancies

I'm a little stuck... Click here to teach me more about this clue!

'occupations' is the definition.
The definition and answer can be both acts as well as being plural nouns.
Maybe there's a link between them I don't understand?

'number reconsidered as nice' is the wordplay.
'number' becomes 'ten' (ten is a kind of number).
'reconsidered' indicates an anagram.
'as'+'nice'='asnice'
'asnice' is an anagram of 'ancies'.
'ten'+'ancies'='TENANCIES'

Can you help me to learn more?

(Another definition for tenancies that I've seen is " property".)

I've seen this clue in The Daily Express.
