Continue marketing to "backup" applicants?

[Bienes Raices]

When you approve an applicant and get the non-refunable holding deposit so that they can move in on the first of the next month, are you supposed to continue marketing and showingt the place to "backup" tenants in case the group that placed the deposit flakes out and doesn't move in?

My theory is that you can continue marketing it until the lease is signed and all of the money is collected. I am assuming you are talking about a lease and not an owner finance purchase.
