I can tell you that it is all harmful. My landleeches have acknowledged that the house we rent needed maintenance before we moved in and have done literally 0 of it in the last year, opting to instead use my wages to improve the other 24 properties they purchased in bulk from a retiring landleech. Then they have the audacity to attempt to illegally evict me and my pregnant wife when I start asserting my rights, and tell prospective landlords we are "problem tenants" who have paid every rent payment in full and on time for the entire lease.

No, there needs to be mandatory, city/borough-wide rental associations that have the legal authority to hold landleeches accountable. It needs to be mandated at the federal level and it needs to have serious teeth.
