The circumstances alone may be significant enough for us to deny tenancy.Once we had a prospective tenant call us, who had an eviction on her record.

If you have over 50 inquiries and this particular applicant did not meet your credit criteria you have every right to deny them and move on to the next inquiry. 

So, protect yourself: document your exact rental criteria in an easy to follow format and keep records of what (legally permissible) reasons you deny a tenant, etc.

I have banks that lend me millions, and had a bank two years ago flat out deny me.  

If they have no credentials, I would feel completely comfortable denying the request. 

This whole situation  sucks because I really consider my GC a friend but I can't take this type of loss especially with him denying any type of error on his part. 

Of course when the insurance company denies him because he is still living there then it's on him.

Sounds logical, but maybe someone else can confirm/deny.

Commissioner, an attorney was denied deductibility for a portion of his residence used as a home office because he failed to meet the exclusive use test.

I asked the seller about that possibility last week, they wouldn't go for me renting it from them and then in turn renting it to someone else, even if they could approve or deny an applicant.
