Leasing process correct order

[Reynier Smith]

Hi I'm a new realtor and going through my first deal (rental). We just submitted the offer to the listing agent and was accepted. My client wired a deposit that is going towards the first month's rent. The lease agreement says the rest of the money os due on the first of the month. The listing agent(which is also the owner) was asking for the rest before she signs the final contract. What is the correct procedure order? send offer, receive response, walkthrough, signing final contract, depositing rest of the money due? Or should we send the rest of the money right after walkthrough and prior to final signing? Thanks.
