You probably have NO option except to get this person out and possibly YOU look over the next app, etc and make the final decision if you want to accept them.

This is a qualified employer retirement plan, not just an "account".So, you have the Ford 401k Plan or the Apple 401k plan, as examples, or commonly the "Smith 401k plan" in a sole proprietor format.While a plan name can be changed, it is not just something you do at will.  

I'm not sure if there is a better app or Facebook page to vent on about this stuff, let me know if this is an inappropriate use of this website! 

I only run one applicant even if I have multiple apps.

I would support a decision to buy at $675k property that brings in $4200 a month in rents under the right terms and in the right neighborhood, and an apples-to-apples comparison would be 675k less transaction fees and taxes (if applicable) that you would net on sale, but that's beside the point.

They also have a mobile app that is very user friendly.  

One has to compare apples to apples.

They even have an app for the company.
