Newbie landlord question

[Aaron Millis]

So I am in the process of getting my first tenants for my first rental property. I've met them and pre screened them- they've seen the property and they're ready to apply. The thing is their lease won't begin until a July 1 (because college). Emailing them the rental application should be simple, but if they all check out how will signing the lease go? Sorry I forgot to mention that they all live states away and won't be back in my town till they move in in July. I'm assuming I would need everyone to sign my lease in person is that right? Also if that Is the case-can I collect the deposit before they all come back and sign the lease? Because I definitely want the deposit now for less risk. Also also can I charge the deposit and the first months rent now? Or can that only be done the day of moving in? Sorry for all the newbie questions, I feel like that have simple answers I'm just trying to make sure I make the right moves.
