Quote from @Jeff Calcaterra: We have a potential tenant new to the area who has gone through a paid background check, signed a background check authorization form, sent us a LinkedIn profile, sent an offer letter and says he is willing to send us paycheck stubs, but says he doesn't want us to call HR to verify employment because he is supposed to have found housing already.

I was sent an offering memo by a broker selling a multi-family building in an area no reasonable person would even consider affordable housing material yet the marketing materials made a point of emphasis to detail how the property would satisfy the need for affordable housing.
