Possible answers include:
less likely to spend more than he has/avoids additional debt
help prioritise his spending according to importance eg paying bills first
process is good self-discipline for the future
appease his mother/encourage her to buy the house.
Examples
Robbie is less likely to get into debt (1) because he can see how much he needs to pay his bills
when they arrive (This is not in context and would only be awarded one mark despite
explanation being present).
If he draws up a budget this will please his mother (1) which means she is more likely to go
ahead and buy the house saving Robbie paying rent (1).
