I'm an agent and landlord in Indiana, so I'm sure the landlord tenant laws differ some. In Indiana, it is quite easy to evict someone if needed. When you say they backed out, did they stop paying rent, move out already? Depending on the details, it is probably best to consult an attorney. I have had to complete two evictions and it's quite easy in Indiana, just have to take the time to file the paperwork with the court. I did both without an attorney, got my judgements for rent owed, late fees, damage to property, etc. I also got wage garnishments set up and got the money owed to me.
