Self-management works until the 20th unit, and then something structural has to change

The assumption doing the most work here is that the 6 percent fee buys a competent manager, and in a lot of markets the property management industry is thin enough that $1,680 a month buys someone who handles calls slower than the owner would and carries deferred maintenance of their own. The real comparison is not owner time versus fee, it is owner performance versus that specific manager's actual occupancy rate and average days-to-lease over the last 12 months, which you can ask for and verify. What shifts the math more reliably than unit count is lease complexity: the moment an owner is holding a mix of month-to-month, fixed-term, and subsidized units across three buildings, the cognitive load stops scaling with the portfolio and starts scaling with the variance. What does the lease structure look like across those 24 units, because that changes whether the threshold is really 24 or whether it was already hit at 16?

The 18 hours number is doing a lot of lifting in this post, and I'd want to know how much of that is reactive versus structured, because those are completely different problems.

My Tennessee stuff is third-party managed from day one, partly distance and partly because I knew I'd romanticize the control argument and talk myself into staying self-managed longer than made sense. The two voucher units alone generate a call volume that would eat a workday just in housing authority paperwork if I were touching it myself.

What unit count did you have when the quality of your own decisions started slipping, not just the hours?

The misconception worth correcting is that third-party management is a binary choice: you either hand everything over or you do everything yourself, and most owners at 20-plus units never look at the hybrid structures that actually fit this range.

At 24 units across three buildings, a part-time property coordinator hired directly, someone at 20 hours a week handling leasing calls and work order intake, typically costs $1,800 to $2,200 a month all-in depending on your market, which is roughly what a third-party manager charges while also building their own vendor margin into every repair ticket. The coordinator model keeps vendor relationships and approval authority with the owner, which is where the real cost control lives at this scale, while offloading the scheduling and phone volume that generates most of the decision fatigue described above. The fair housing exposure point is sharper than most owners realize: it is not the hard calls that create liability, it is the 11pm text answered without thinking, and a coordinator with defined office hours and a written escalation protocol removes most of that surface. What I would want to know before recommending either path is how the three buildings are distributed geographically, because if they sit within a few miles of each other a coordinator can run them efficiently, but if one is 40 minutes out it functionally behaves like a separate portfolio and the math on each option changes.

Shifted at 14 units for me, not 20.
