Housing Contract Expiration Date **URGENT**

I submitted my $50 fee months ago, but just received my housing contract last week. It expires tomorrow (Sunday), and I stupidly waited for today (Saturday) to pay the $300 enrollment fee and sign the contract (under the impression I could do so electronically). However, I will not be turning 18 until September so I’m left to scan and email my contract to the housing office.

If there’s no one in office until Monday, will my contract will become void or will it still be accepted since the email’s postmark says it was sent today?

And, if it is void, will I have to reapply for housing??
