> Funnily enough, I work adjacent to a company called Rent Dynamics, and one of the features that they offer is positive credit reporting for those who pay the rent on time. There are others that do this too.

I actually feel that such companies should not be allowed to report a tradeline.

No company / landlord (and doubly so when you go with, as you say, 'not-quite-slumbs') is offering you rent in arrears. You're paying, in advance, and no credit was extended to you.

To me this is a bastardization of the credit system that's only got potential positive reporting as a side effect. Let's be real, companies like yours real customers are landlords/property managers, not tenants.
