I don't think I am a big fan of someone who came into my unit, broke the lease, destroyed my unit, took off, and still want to get all the money back.

Tenants who have been screened properly generally will not destroy your property and will usually give you notice, allowing you to market the property while still occupied, have a new tenant lined up ready to go, and move them in very soon after the prior tenant leaves.  

You could get a tenant that moves in and decides not to pay again and proceeds to destroy the property.  

A remodel was started but abandoned, it's sat for five years, the roof leaks and has now destroyed the ceiling.

I want it to hurt enough to incentivize timely payment, but to be reasonable enough not to destroy my relationship with a tenant when I charge it.

Somebody tell me how to get back at these morons for destroying deals with incorrect information.  

They destroy your units, doing hundreds or even thousands of dollars in damage. 

I had to redo the apartment after Stephanie pretty much destroyed the place when she moved out 2 years later and after I paid for a dumpster, new paint, bed bug removal, and labor plus rental income loss I realized I could have done more research into her living habits.

Haines City, FL... tax deed on what public record said was a 4/3 @ 2300 sq ft that ended up being a vacant lot because fire had destroyed the home and the town fored the owner to demolish.

As @William Hochstedler said, I've seen 2/2 units leased to two individual undergrads completely, totally, 100% destroyed in under a full fall/spring semester lease.
