how do you get the proper kb for a transaction before you even create it?
As CIYAM has pointed out, you don't. First you create the transaction, then you calculate the fee.

Okay - refer to this: https://en.bitcoin.it/wiki/Transaction_fees
Just create it the raw tx (with no fee) but don't send it and check its size (and the age of UTXOs if necessary) - remember that paying the fee is simply reducing one of the outputs (generally the change one) by the appropriate amount.
