The agent or owner can accept any amount as rent in advance however the agent can't ask for more than 2 weeks.
The other issue yet to be raised is what if the tenant wants to break the lease & the owner has spent the rent money?
You're up for it. If they were able to get a deduction for the rent paid, they'd be claiming it this year too.
If you can, prepay your interest for the year so it won't hit you as hard.
PS: will they be running a meth lab from the place?
