For an industry that runs on data, multifamily has an uncomfortable truth to confront: many operators don’t actually control theirs.
It’s not intentional. It’s structural.
Over the past two decades, property management systems (PMS) have become the operational backbone of the industry as the system of record for leasing, accounting, service resident records, renewals and more. And over time, they accumulated something even more valuable than functionality: your historical data.
Years (sometimes decades) of leasing performance, pricing decisions, resident behavior and operational outcomes now sit inside systems that are notoriously difficult to leave. Not because operators lack the will...but because the cost, complexity and risk of extracting that data feels overwhelming.
In fact, Gartner estimates that as much as 60–80% of enterprise data remains locked inside legacy systems—a reality that should feel uncomfortably familiar to multifamily operators.
So companies stay. Even if frustration grows.
Ask almost any operator how they feel about their PMS, and you’ll hear a mixed refrain: reliable and robust...but also cumbersome, outdated, inefficient and constraining. Yet despite significant dissatisfaction among many operators, meaningful migration remains rare.
Why? Because the switching cost isn’t just financial—it’s informational.
For larger portfolios, system migrations can stretch 6 to 18 months or more, with data migration alone accounting for up to 40% of total project costs, according to firms like Deloitte and PwC.
When your data lives inside a system you don’t fully control, you’re not just buying software. You’re in a long-term dependency model.
And that dependency has ripple effects.
It limits innovation. It slows adoption of better tools. And perhaps most critically, it creates barriers for emerging proptech solutions trying to integrate into the ecosystem. High integration fees, restrictive APIs or outright resistance to third-party connections aren’t uncommon. The result? Operators are often left choosing between “what’s available” and “what’s actually better.”
That’s not a technology problem. That’s a control problem.
But there’s a shift underway—and it’s happening quietly. Forward-thinking operators are beginning to rethink where their source of truth lives.
Instead of relying exclusively on their PMS as the central repository of intelligence, they’re layering in business intelligence platforms like REBA. Not just for reporting—but for ownership.
Because when you implement a BI overlay, something important happens:
Your data starts living somewhere else, too. Leasing activity, pricing performance, operational metrics—all begin flowing into a system designed not just to store data, but to structure, analyze and act upon it.
At first, the value is clarity. Better insights. Faster decisions. More transparency into what’s actually driving performance. But over time, something more strategic emerges: optionality.
As that parallel data environment matures, operators are no longer solely dependent on their PMS for historical context. They’ve effectively built a second foundation—one that they control. And that changes the conversation.
Suddenly, evaluating a new PMS—or any major system change—doesn’t feel like starting from scratch. The fear of losing institutional knowledge diminishes. The risk of disruption becomes manageable.
And the upside is real. According to McKinsey & Company, organizations that truly leverage their data are significantly more likely to outperform peers in profitability and growth.
In other words, the lock-in doesn’t just create friction—it creates missed opportunity.
This isn’t about ripping and replacing systems overnight. It’s about creating leverage.
Because the most forward-looking operators are not asking, “How do we replace our PMS tomorrow?” They’re asking, “How do we make sure we’re never stuck again?”
Owning your data—or at least ensuring it exists beyond a single system—is the first step. And in a market where agility, precision, and speed increasingly define competitive advantage, that step may be one of the most important you take.
