If I own the property 100%, can I get a mortgage immediately?

[Louis Porter Jr.]

So I am planning to buy a property in Northern Florida for cash ($70K) and after the purchase, I am planning to get a mortgage for this property ($83K). How long do I have to wait to get a mortgage on this property? I keep hearing LOTS of different answers on this one online in random places, but I was hoping I could get a more "professional" real world answer here? Thanks!
