I 100% agree with others, in that tenants are very smart, and if yours is overpriced, it will sit.. and sit.. the market tells you the correct price, and it verifies it based on tenant reactions.   

Gut reactions are important, and sometimes even just asking to schedule a visit can reveal a lot about how a provider actually handles customer service.

You can't sell a property to yourself (I'd love to see the title company's reaction when they go to receipt that contract!

You have confirmed our initial gut reaction, that they do not need this info, but we also wanted to make sure this was not something that just comes up occasionally and it would look like we were hiding something if I didn't comply. 

Since its a bad tenant, who knows what her reaction would be to being evicted.

My first reaction was mold and re sale issues.

It sounds like you're asking for a lot more off if they aren't willing to negotiate at all.I agree that it sounds like you're not approaching motivated sellers if this is the reaction.

Another question is lender's reaction to this issue.

Although I feel like your current resident may comply, having a early termination clause sort of negates some of that unknown reaction.

My gut reaction is that there isn't much of a value proposition for potential buyers based on what you'd have to charge vs what their money gets them with other options.
