Since signing the leases, the downstairs tenant has expressed several times that she would like to get a dog, which I have denied per her lease.

When they know you're the decision maker you'll get every request under the sun and it's a lot easier to just be the messenger and blame the "Owner" for denying the request. 

Our loan guy couldn't figure out how much we had and had to deny otherwise. 

Legally, those who cannot pay cannot be denied care.

If he is, then the follow up is I need a full and complete application for him too...at which point I would deny if there were problems.

Zoning denied the purchase of a 19 bed property that was previously used as an assisted living facility for the following reasons:1.

What Denis said is a good rule of thumb.

The only issue I've been having (so far) is being denied mortgage loan due to income/debt ratio being too high.

In my case, they denied me primarily because I didn't have at least 2 off-street parking spots per unit (4 total, in this case), and although there is a 2-car at the property, they wouldn't even count that, leaving me with 0 off-street parking spots in their eyes.They had some other reasons as well, but off-street parking seems to be a favorite of municipalities around here to quickly DQ such a request.

Does every potential tenant go through the full application process or can you deny them just based on the prescreening?
