I'm controlled by the cats
We seem to be assuming that Steven wasn't paying his rent because he had no money -- but what if he had been planning on leaving town and opted to save his income (in a shoebox under his bed or something) rather than using it to pay rent?
Exactly how much was he making washing windows? I'm assuming this was not steady income. But was he being paid in cash and how often?
It may be that the only money left in his bank account had been transferred there by his mother and she took the money out after he disappeared. It sounds like she or both parents may be joint owners on the account.
