Colin, where would Oswald keep his life savings?

I figure, he could keep on his person. He could keep at the rooming house. He could keep in a bank account. He could keep at the Paine's in Marina'a room.
Given he was paid weekly in cash and had not seen Marina for two pay periods he was relatively "cashed up" that Thursday. Given he did not go back to the rooming house before visiting Marina he obviously did not keep it at that location. I don’t believe he had a bank account. So, to take his total saving to work on the Friday seems risky. Safer to leave all but what he needed with Marina. Then again if he was going to shoot the Pres with no escape plan no need for $15. If he planned to escape, take the lot. If he had planned by Thursday morning, why not take the pistol too?
