To add to this, I ask that all communication with tenants be in group format that way there is no "he said, she said" issues. 

My brother owns a condo in the Fayetteville, NC area and recently got a letter from his tenant's lawyer stating that they have filed bankruptcy and that he could not directly communicate with the tenant until the bankruptcy was complete.  

I've met with one, but I'm looking to find one that is a bit more responsive to communication than who I'm currently using.

We would suggest constant communication and review of budget status as you go along- weekly at minimum.  

You should be able to document that fortunate accident and had other things like written communication, the lease itself, your past practice etc all demonstrating that your intent was to hold.  

I've been using the same company for five years, but the last year or so has been a steady downward spiral of bad communication, poor service, and now almost zero effort on rerents of vacant units. 

Your job at this point is to listen to your DB, stay calm, and communicate in a very businesslike manner.

Additionally: whatever you do about this, try to stick to email (other written communication) that you can later go back to in case the tenant decides to claim that he was not fully reimbursed.(1) Ask the former owner for any Lease he had with this tenant (it sounds like you were this tenant's landlord for 6 days - I'd ask for this document during the purchase period.)  

I would try texting the listing agent - she's had this property listed on and off since 2008 and has been dealing with the short sale (what a pain for an agent) - she's probably sick of it, not making any money on it and has probably been fielding a million calls from completely unqualified first time buyers who want that area but don't really pay attention to the details and don't have any cash - I would be clear in your communication with her that you understand the requirements and have the cash to close - I've had transactions with her in the past she's been around for a long time.  

The claim was easy and communication was great.
