tenant not paying. whats next step?

[Mike Wallace]

Last month my tenant paid half the rent with promises to pay me the remaining half in 3 days. He paid another portion, but was still short $50 on total rent.

This month (november) I told him full payment had to be in by the time the bank closed on the 5th. ( my tenants deposit rent in my bank account). He failed to do so, with no response from my text message.

He has been there for 10 months and never had a problem before.

Whats next?
