Meanwhile at home, call about investments, initially (7)
I believe the answer is:
interim
'meanwhile' is the definition.
(thesaurus)
'at home call about investments initially' is the wordplay.
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'call' becomes 'term' (terming is a kind of calling**).
'about' indicates putting letters inside.
'initially' indicates taking the first letters.
The first letter of 'investments' is 'i'.
'term' going around 'i' is 'terim'.
'in'+'terim'='INTERIM'
(Other definitions for interim that I've seen before include "not there for ever" , "temporary period" , "Meantime - provisional" , "Meanwhile" , "An intervening period of time" .)
