Incentives For Tenants To Take Care Of Property?

[Robert Smith]

I know your lease agreement should list what happens if the tenant does not take of a property or damages something, but I'm curious what some of you have thought up to add an extra incentive to motivate tenants to take care of the property? 

Also, what are some additional things you check for on the front end to rule out possible tenants that may not care for a property or cause more issues? I'm aware of calling previous landlords if the tenant list them, and employers, etc., but just trying to see if anyone is applying a new/different approach that has proven successful?
