Turnover Is the Multifamily Expense Nobody Budgets Correctly

Multifamily turnover cost is the most consistently underbudgeted line item in the entire operating model, and the reason is structural: the largest component never lands on the expense statement. Operators budget the make-ready, the paint, the carpet, and the leasing fee, because those are invoices. They rarely budget the lost rent, the vacancy days, and the concession it takes to re-lease at a market that may have moved. When a resident leaves, the invoice is the small part. The economic cost is two to three times larger, and it hides across three different lines of the model. That gap compounds, and it is why two identical assets with different retention can post materially different NOI on identical rents.

Key Takeaways

Apartment turnover held near $3,872 per resident, and NAA data showed a 17.5% year-over-year jump in turnover costs in 2024, per Multifamily Dive and the NAA Income/Expense IQ report.
The largest piece of turnover cost, lost rent during vacancy, never appears on the expense line, so budgets that only count invoices systematically understate the real number.
A worked example shows a single turn on a $1,500 unit costing roughly $4,500 all-in once 30 days of lost rent and a concession are added to the hard make-ready cost.
At 50% annual turnover, a 300-unit property turns 150 units a year; at $4,500 all-in, that is $675,000, a figure most budgets book at less than half its true size.
Retention is the cheapest revenue in the model: every renewal avoids the full stack of turn cost, which is why a one-point retention gain outperforms a one-point rent bump.

What Is Multifamily Turnover Cost, And Why Is It Underbudgeted?

Multifamily turnover cost is the total economic cost of a resident vacating and being replaced, spanning make-ready, marketing, leasing, and lost rent during the vacant period. It is underbudgeted because only the make-ready and leasing pieces arrive as invoices. The lost rent and concession pieces, often the largest, escape the expense budget entirely.

The reported averages already sit higher than most models assume. Apartment turnover cost held near $3,872 per resident, per Multifamily Dive, and the National Apartment Association's Income/Expense IQ report showed leasing expenses rising 4.6% in 2024 to $292 per unit, driven by a 17.5% year-over-year increase in turnover costs. An NAA survey of property managers found that 53.8% reported average turn costs between $1,500 and $3,500 per unit, with 19.4% above $3,500.

Those figures are the visible part. The turnover cost that appears on the P&L is the make-ready and leasing spend. The lost rent lives in vacancy loss, and the concession lives in other income offsets or effective-rent adjustments. Because the pieces are scattered, no single line tells the operator what a departing resident actually cost, and the budget almost never sums them.

How Much Does A Single Apartment Turnover Actually Cost?

A single turnover costs roughly two to three times the hard make-ready invoice once lost rent and concessions are included. Industry ranges put the all-in cost of a standard turn between $2,000 and $5,000, and units needing significant work run far higher. The wide range exists because the largest variable, days vacant, tracks market conditions.

Here is the worked example, built from stated inputs so every number traces to an assumption. Take a unit renting at $1,500 per month, which is $50 per day. Assume the unit sits vacant for 30 days between residents. That is $1,500 in lost rent. Add a hard make-ready of $2,000, cleaning, paint, minor repairs, and turn labor, near the midpoint of typical ranges. Add $500 in marketing, screening, and administrative cost. Add a one-month concession to win the new lease in a competitive market, another $1,500 against effective rent. The total is $5,500 in the concession case, or $4,000 if the market is tight enough to skip the concession.

Turnover cost component	Where it appears	Example amount
Hard make-ready (clean, paint, repair, labor)	Repairs and maintenance expense	$2,000
Marketing, screening, administration	Leasing and marketing expense	$500
Lost rent (30 vacant days at $50/day)	Vacancy loss, not an expense line	$1,500
Re-leasing concession (one month)	Effective rent / other income offset	$1,500
All-in total	Spread across three parts of the model	$5,500

The invoice-visible portion, make-ready plus marketing, is $2,500. The full economic cost is $4,000 to $5,500. A budget that counts only the invoices captures roughly half the number, and it captures the wrong half, because the lost-rent and concession pieces are the ones that move with market conditions and blow up in a soft leasing environment.

How Does Turnover Cost Scale Across A Portfolio?

Turnover cost scales with the turnover rate multiplied by unit count multiplied by all-in cost per turn, and at portfolio scale the total becomes one of the largest controllable operating exposures. National turnover has fallen as operators prioritized retention, but even at reduced rates the aggregate figure is large enough to swing property-level returns.

Retention has improved recently, and market-rate turnover commonly runs in the mid-40% range. Class B and C assets often run higher, in the 45% to 55% range. The tenant retention rate is the lever, because every renewal avoids the entire stack of turn cost, not just the invoice.

Run the portfolio math. A 300-unit property at 50% annual turnover turns 150 units per year. At the $4,500 midpoint all-in cost from the worked example, that is $675,000 in annual turnover cost. If the budget books only the $2,500 invoice-visible portion, it records $375,000 and misses $300,000 of real cost that leaks through vacancy loss and concessions. Scale that to a 3,000-unit portfolio and the understatement runs into the millions. This is not a rounding error. It is the difference between a budget that ties to reality and one that does not.

Why Does Retention Beat Rent Growth In The Model?

Retention beats rent growth because a renewal avoids the full turnover cost stack while a rent increase only adds to gross revenue before that stack is deducted. A single point of retention captures the entire avoided cost of a turn, which at the property level often exceeds what a point of rent growth delivers.

The math favors keeping the resident. A renewal at flat rent still beats a turnover that re-leases at a modest increase, once the vacant days, make-ready, and concession are netted out. As one NAA analysis of turn economics framed it, the most profitable lease a community signs is often the one it renews, because retention is the only revenue that arrives with no acquisition cost attached. Rent growth is gross. Retention is net, and net is what reaches NOI.

There is a second-order effect on financing and value. Turnover-driven vacancy and concessions depress effective gross income, which flows straight to NOI and, through the cap rate, to value. Chronic underbudgeting of turnover also distorts the exit: a buyer who underwrites the true turn cost will discount a seller's optimistic NOI, and the bad debt and vacancy assumptions that get glossed over at acquisition surface at disposition. Modeling turnover honestly is not conservatism. It is accuracy, and accuracy is what survives the diligence of a sophisticated buyer.

Frequently Asked Questions

What is the average cost of an apartment turnover? Apartment turnover held near $3,872 per resident, per Multifamily Dive, and NAA survey data shows most operators report $1,500 to $3,500 per unit, with about one in five above $3,500. All-in costs including lost rent and concessions often run higher, in the $4,000 to $5,500 range for a standard unit.

Why do turnover budgets understate the real cost? Because the largest components, lost rent during vacancy and re-leasing concessions, never appear as expense-line invoices. Budgets that count only make-ready and marketing capture roughly half the true economic cost, and they miss the half that swings most with market conditions.

How much can retention save a multifamily property? Every renewal avoids the entire turnover cost stack. On a 300-unit property at 50% turnover and a $4,500 all-in cost per turn, cutting turnover by 10 percentage points prevents 30 turns, saving about $135,000 a year in avoided cost.

Where does turnover cost show up in the operating model? It is spread across three places: make-ready in repairs and maintenance, marketing and screening in leasing expense, and lost rent and concessions in vacancy loss and effective-rent adjustments. Because it is scattered, no single line reveals its full size.

Conclusion

Turnover is the multifamily expense nobody budgets correctly because the model was never built to sum it. The invoices land on the expense statement, the lost rent lands in vacancy loss, and the concession lands in effective rent, so the operator sees three small numbers instead of one large one. Add them and the picture changes: a departing resident costs two to three times what the make-ready invoice suggests, and at portfolio scale the understatement runs into hundreds of thousands or millions of dollars a year. The operators who model turnover honestly, and who treat retention as the cheapest net revenue in the building, will underwrite closer to reality and defend their NOI when a buyer's diligence tests it. The cost of a resident leaving was always there. Most budgets just were not looking in all three places at once.
