Waiting for Tax Refunds

Two apartments full of tenants owe us two months rent now (Dec and Jan - Feb is out of the question - lol!).  Both claim to be waiting for their tax refunds to come in and then they will get caught up.  We will see.  Hubby is ready to take time off from his "day job" to start eviction proceedings if necessary.  Some of these people should get creative writing jobs - they always have a story for everything!
