Has anyone denied an application that they've already approved?

I've seen Allstate and State Farm drag claims and deny claims for the dumbest reasons. 

I don't have the option to deny an application just because they have a voucher, but even if I wasn't required, I am happy to have a voucher holder in a C neighborhood, and with a little effort, I almost always get paid what I am owed. 

Supply house took windows back pending any credit from manufacturer , it was denied all the paperwork was correct .

We will likely deny him and serve them notice again, as I always see him when I'm up there.

They like to back out of deals when we have multiple people going in and out and legally allowed to deny us a walkthrough. 

Quote from @Denis Ponder: Are you managing the property? 

We have a PMI of $250 a month and I’d love to get rid of it.I contacted the bank for a request for PMI to be lifted and they denied it.They said I could order an assessment of the house through them and then if house / condo come up with enough gained equity then it might be possible .Does anyone know the best first initial steps to order a home assessment ?

If you don’t, Facebook will figure it out and probably deny your ad and it will never run.

Would I get denied because of the recent transfer or would the asset value alone be enough?
