Prospective tenant does not have deposit until move-in day

[Terri B.]

I'm in the process of renting my STR out for month to month during the winter season. Prospective tenant has already presented some.red flags but I said we can be more lenient bc it's short term. To protect my interests I require the deposit and first month rent within 3 days of signing the lease to secure the property. I also do not sign the lease until I recieve the full move in costs and do not accept partial payments. Prospective tenants now are saying they cannot pay the full move-in costs until move in day when it was supposed to be within 3 days of signing. This presents another red flag and at this point I'm leaving the property open to others to rent and pursuing a potentially better tenant. Do you forsee there being any issues with me backing out of approving their application at this point? They have signed the lease but no deposit or rent paid and my lease has a clause which says the lease is void without payment within the time period allotted.
