I trying to picture your explanation to a judge of why you think the tenant should pay $700. 

If you re-do the questions/form you may add an explanation section.  

tenant explanation is that intends to file a 1099 for each year she is owner's tenant to make sure rent paid is being reported as rental income and not 'written off' =D

You'll need to hire a lawyer, or learn the laws yourself.Here is an explanation of the law on the Florida Bar Association website:http://www.floridabar.org/tfb/TFBConsum.nsf/0a92a6...Here is the bar association's lawyer referral info:http://www.floridabar.org/tfb/TFBConsum.nsf/48E762...They will refer you to a lawyer and your first 30 minutes with a lawyer will only cost you $20 - $50. 

I may even have them write a statement of explanation prior to making a final decision. 

@Joel Owens Thanks for the explanation.

He should prepare a packet explaining the property is under new ownership, along with the necessary contact/emergency information, and an explanation of the new rent payment process.Very important: Be sure all security deposits held by the previous owner are transferred to your PM's trust account.And yes I have seen those "do not disturb tenants" in listings many times and it drives me crazy.

You can appeal their credit decisions, normally, with an explanation of why your bad debt is over the ceiling they normally allow, etc.  

Some other plausible explanation?????

Give the tenant the required 30 day notice to terminate the lease as no explanation is needed.
