@John Lenhart and @Evan Polaski make some very good points here. The City of Cincinnati is comprised of around 60% renters and VERY leftist local politics (at least our last two mayoral elections were between two Democrats), so it shouldn't surprise any local investors that City Council is doing what they think is beneficial for lifelong tenants.
It's very valuable to keep in mind that WE are the entrepreneurs in this equation. The original definition of "entrepreneur" is anyone who transfers assets from lower-yield investments to higher-yield investments. City Council isn't doing anything about the number of people who will need rental housing in Cincinnati, so if the investor demand for apartments within city limits goes down, cap rates will increase, and those of us who are good at what we do will figure out how to reap the benefits.
Now that I've said my grandiose and hopeful piece, a couple of nitpicks:
Is there anything stopping us from verifying a prospective tenant's assets as well as their income? As an agent who works with investors, I ask for proof of funds all the time. Can we ask for proof of reserves from tenant applicants?
Do we know yet whether or not landlords will be able to dictate which deposit insurance provider our tenants may use?
When does the law officially take effect? Will it have any impact on renewals of leases the predate the effective date of the legislation?
