OP. There's no need to go asking a date about finances before the appropriate time comes up all by itself.
Just protect yourself in the meantime by not making silly choices ... Such as living with someone before you know them properly. Or even worse.. Having a baby with someone you don't know well.
By the time in-depth financial discussions come up you will hopefully know the other person really well and can make a decision on your future based on all factors (not just whether they rent etc).
