SFR with College Student Tenants, How to handle post-lease inspection?

[Mark Stoker]

I am pretty pumped about buying my first rental property in Tempe Arizona! There are college student tenants currently occupying and whose lease is up in about 3 months. It occurs to me that I don't really know the condition of the property prior to them moving in and when they move out I will need to do an inspection. How can I know/prove if they have cause damages to the property without knowing the condition of it prior to their lease? Any advice is greatly appreciated.
