That's not an opinion. It's the Boston Housing Authority's own math — an 84% difference between helping a struggling tenant stay and removing them. For a property owner, keeping a good tenant isn't charity. It's the better spreadsheet.
The single clearest number comes from the Boston Housing Authority, which compared what it cost to maintain a struggling tenancy against what it cost to evict and replace it:
That's an 84% savings for keeping the tenant — the same unit, the same lease, kept current instead of turned over. The Syracuse Housing Authority ran its own version and saved roughly $167,500 in eviction-related costs through a diversion approach. These aren't advocacy numbers; they're operating budgets. The organizations that run both sides of the equation — the keeping and the evicting — found keeping wins by a landslide.
Why is the gap so enormous? Because the eviction itself is the cheapest part. What follows it is where the money goes. When a tenant leaves, the costs stack up fast:
Stack those against the cost of helping an existing, known, mostly-reliable tenant through a rough month, and the spreadsheet isn't close. A late payment is a cash-flow timing problem. A vacancy is a hole in the P&L.
Eviction diversion programs — which bring landlord and tenant together before a case is decided — exist precisely because this math is real, and they've produced a track record worth paying attention to as an owner.
Read those as a landlord and the message is simple: in roughly 9 out of 10 cases, there was a resolution available that kept the unit occupied and the rent flowing — and the only thing standing between the owner and that outcome was a structured way to reach it before the courthouse took over. Diversion programs supply that structure publicly, with mediators and sometimes rental assistance. The lesson for your own portfolio is that the structure itself is the valuable part.
You don't have to wait for your county to run a diversion program to capture these savings. The core of what makes diversion work — early communication, a clear payment path, and a reason for both sides to choose resolution over removal — can live inside the way you manage the property itself. The goal is to make "work it out and keep the tenant" the automatic path, and "file" the rare exception, instead of the other way around.
Diversion works because it interrupts a foregone conclusion. The default in eviction court is removal. Change the default, and most tenancies survive — profitably.
Perfect Tenant Innovation turns the diversion principle into always-on infrastructure for your portfolio. It rewards on-time payment and reports it to build the tenant's credit — so staying current is something your tenant is personally invested in, not just something you chase. It gives you an in-app payment-plan path, so a rough month becomes a structured arrangement instead of a court date. And its monitoring and reporting run passively in the background, giving you the early visibility that makes a problem solvable while it's still small — the exact moment diversion research says resolution is cheapest.
The result is the $1,570 outcome instead of the $10,021 one, by default, across your whole portfolio — a known tenant kept paying instead of an unknown one gambled on. Retention stops being a soft virtue and becomes what it actually is on the spreadsheet: the cheaper, smarter way to run rental property.
Perfect Tenant Innovation makes retention the default — a passive system that keeps good tenants paying and your units occupied. For portfolios from 1 to 500+ units.
