Rental ad response and holding rental

[Jeremy England]

so I just finished a rehab on a new acquisition and posted my ad to Zillow for 1000/mo which I thought was ambitious.  I got blown up with tenant requests and had an agreement in a day.  However they were not able to come up with the required security deposit so I reposted it to Zillow and again am getting a lot of response

Now I’m faced with tenants asking me to hold the property for them. Good tenants coming from out of town.  Military town.  I’ve been telling them that I can’t hold it due to demand and my need to place a tenant now.  Its only been one day since I reposted it.  Got two coming to look today. One for a second time but they say they can’t occupy til October. How does the community deal with the holding issue?
