In short, in most states this is legal. As a landlord I will ask for paystubs as proof of employment. However, since the lease is already in effect, there is only one reason I can see for asking.
Chances are this complex gets government subsidies, similar to Section 8, but without the renter having to apply for section 8, etc.. If all of their tenants are below a certain income level, they can request for a tax credit from the state. This may not be known to the tenant and many properties do this without their tenants knowledge.
The other reason could be that they are selling the property, and want to show the prospective buyers that the tenants are gainfully employed and are able to pay their rents.
I would just ask, they should tell you without fuss.
Just my
anyway. Hope it helps
