An owner with two managers asks both for turn time. One reports seven days. The other reports thirty-eight. The obvious conclusion is that one manager is dramatically outperforming the other.

It may be completely wrong. Both numbers can be accurate while describing two portfolios doing near-identical work, because turn time has no agreed definition and the two managers started their clocks in different places. This article covers what the published benchmarks actually disagree about, how one unit can legitimately produce six different turn times, and what to require in a report so the number means something.

The Benchmarks Do Not Agree, and Some of Them Say So

Look at what the industry publishes under this label. Operational guides commonly cite five to seven days as a standard turn target, with full renovations running ten to fourteen. Turn management vendors quote the same five to seven day range for standard scope work. Some housing guidance goes further, suggesting forty-eight to seventy-two hours in high-demand markets.

Then look at the market data. RealPage reports average vacant days for stabilized units at 34.4 as of the end of 2024, measured from move-out to the next resident moving in. Maintenance operators citing RentCafe put the 2025 multifamily market average at 41 days vacant per turn, with workforce multifamily running 45 to 60 days and single-family rentals 30 to 45.

Five days and forty-one days, both describing the gap between residents, published within roughly a year of each other.

Notice that RealPage does not call its figure turn time at all. It calls it average vacant days, which is more precise and describes the same span that other publishers label as a turn. The naming problem runs through the data itself, not just through the reports built on top of it.

This is not a case of some operators being seven times better than others. At least one publisher has said as much directly. Lula's guidance notes that a standard make-ready can be quoted at three to five days when only the sequenced work time is counted, or five to ten days when the full calendar span is measured, and that both figures are correct because they are measuring different clocks. The same source observes that despite how often the term is used, make-ready is not defined consistently across the industry.

An analytics vendor puts the practical warning more bluntly, telling operators to measure move-out to move-in rather than make-ready alone, and to include marketing and leasing days rather than maintenance days only.

The disagreement is documented. It just does not travel with the number when the number reaches an owner report.

One Unit, Six Turn Times

Take a single apartment and follow it through an ordinary turnover. Rent is $1,500, so each vacant day costs about $50.

The resident gives notice on 1 January. The lease ends and they move out on 31 January. Keys come back on 2 February. Trades run from 3 to 9 February. The unit is rent-ready on the 9th. It leases on 25 February. The new resident takes possession on 10 March.

Every measurement below is defensible. Each one is in use somewhere.

Same unit. Same work. Same calendar. Four days to thirty-eight, a factor of nine, before anyone has done anything differently.

Only one row on that table describes money that actually left the building. Rent stopped on 31 January and started again on 10 March, so the vacancy loss is $1,900 regardless of which figure gets reported. A manager reporting seven days is not lying. They are reporting the span they control, and it is a real operational measure of their maintenance function. It is simply not the number that reconciles to the rent roll.

Why the Definition Drifts Toward the Flattering One

The explanation is duller than deception, and more durable because of it.

Turnover crosses several functions. The property manager owns the lifecycle, maintenance owns the physical preparation, and leasing owns marketing, screening and lease execution. As one industry guide puts it, the common failure is that nobody owns the seams between those functions, and the days lost there do not appear in any single team's KPIs.

Every team therefore reports the span it can influence, which is reasonable. Maintenance reports make-ready days because that is their work. Leasing reports days on market because that is theirs. The gap between the unit becoming ready and the unit becoming occupied belongs to no one, so it gets reported by no one, and it is usually the largest component.

None of this involves a decision to mislead. It is a series of teams answering honestly about their own scope, assembled into a report that never asks who is counting the dead time between them. The effect, though, is directional rather than random. The metric improves whenever the definition narrows, so an operation can cut its reported turn time substantially without turning a single unit faster, simply by moving the start of the clock from move-out to key return.

What the Ambiguity Costs

Two costs, and the second is larger. The reporting gap. Run the portfolio arithmetic. Take 200 units at $1,500 rent with 50 percent annual turnover, so 100 turns a year, each vacant day costing $50. At a reported seven-day make-ready, the apparent vacancy cost is $35,000 a year. At an actual 38 days vacant, the real cost is $190,000.

The $155,000 difference is not hidden by anyone. It sits in the rent roll and shows up in the vacancy line. It simply does not appear in the metric the owner was given to judge performance by. A CFO reading a seven-day turn time and a $1,323 per unit vacancy and rent loss figure has two numbers that cannot both be describing the same operation, and no obvious prompt to notice.

The comparison failure. This is the expensive one. Benchmarking assumes a common definition, and there is none. A manager reporting 38 days on a move-out to move-in basis will lose a comparison against a manager reporting 9 days on a move-out to rent-ready basis, even if the first is running the better operation on every dimension that matters.

The same problem applies internally. Comparing properties, regions or years only works if the definition held constant across all of them, and definitions tend to change quietly when systems are replaced or reporting is rebuilt.

There is real money on the line, which is what makes the ambiguity worth fixing rather than tolerating. The 200 unit portfolio above loses roughly $205,000 a year to vacancy at market-average days vacant, and cutting ten days off the average recovers about $50,000. Those are decisions worth making on a number that means what the reader thinks it means. Turnover costs reported from NAA's 2024 benchmarks rose 17.5 percent year over year, so the stakes are rising rather than steady.

What to Require Instead

Four things, none of which need new systems.

• Publish the definition next to the number.
  Not in a footnote, in the same line. "Turn time 38 days, measured move-out to move-in." This single change resolves most of the problem, and it costs nothing.

• Make move-out to move-in the headline figure.
  It is the only definition that reconciles to vacancy loss on the rent roll, which makes it the only one a finance function can use. Everything else is an operational sub-metric.

• Report make-ready as a component, not a substitute.
  Days from move-out to rent-ready is genuinely useful, because it isolates the maintenance function's performance from the leasing function's. Report it underneath the headline number, clearly labelled, so nobody mistakes one for the other.

• Look at the gap between them.
  If make-ready is nine days and days vacant is thirty-eight, the twenty-nine day difference is leasing and coordination time, and that is where the recoverable money usually sits. A wide gap is more actionable than a good make-ready number.

One practical note on where the figures come from. Any of these definitions can be calculated correctly, but only if the underlying timestamps are captured consistently: notice date, move-out date, key return, work completion, listing date, lease date, possession date. When those live in a spreadsheet maintained by hand, the definition tends to shift as the person maintaining it changes. When they are generated by the system as events occur, the definition holds still, which is the actual prerequisite for comparing anything to anything.

Conclusion

Turn time is one of the most quoted numbers in property management and one of the least specified. The published benchmarks range from five days to forty-one for comparable properties, and the range exists because the industry is using one label for at least six different measurements.

None of the definitions are wrong. Make-ready days, days on market and days vacant are all real, all useful, and all describe something a team is genuinely accountable for. The failure is that they share a name, so the number arrives at an owner or a CFO stripped of the one piece of information required to interpret it.

The fix is not a better metric. It is a disclosure. State where the clock starts, state where it stops, and put that on the same line as the number. Every comparison downstream becomes valid, and the ones that were never valid stop being made. Platforms such as RIOO make this practical by recording each turnover milestone as it happens rather than relying on a manually maintained spreadsheet.

A turn time without a definition is not a performance measure. It is a number that happens to be true about something.

FAQs

1. What is turn time in property management?
Turn time is the period a unit is unavailable between one resident leaving and the next taking possession. The difficulty is that there is no agreed start and stop point. Depending on the definition in use, it may mean the days of trade work, the days from key return to rent-ready, or the full span from move-out to move-in. Published benchmarks range from about five days to over forty as a result.

2. Which turn time definition should we use?
Move-out to move-in should be the headline number, because it is the only definition that reconciles to vacancy loss on the rent roll and therefore the only one useful to a finance function. Make-ready days should be reported underneath it as a component measure of maintenance performance, clearly labelled so the two are not confused.

3. Why is our turn time so much lower than our days vacant?
Almost certainly because they are measuring different spans. Turn time as commonly reported by maintenance teams covers move-out to rent-ready. Days vacant covers move-out to move-in, which adds marketing, application processing, lease signing and the gap before the new resident actually arrives. That leasing tail is frequently longer than the make-ready itself.

4. Can turn time be improved without improving operations?
Yes, which is the central risk with an undefined metric. Moving the start of the clock from move-out to key return, or the stop from move-in to rent-ready, reduces the reported figure without changing a single day of actual vacancy. This is rarely deliberate. It usually happens when reporting is rebuilt or a system is replaced and nobody records what the previous definition was.

5. How much does an extra vacant day actually cost?
Divide monthly rent by thirty. At $1,500 a month, each vacant day is roughly $50. Across a 200 unit portfolio with 100 turns a year, one day off the average recovers about $5,000 annually, and ten days recovers about $50,000.
