Ask a property management company what it costs to sign a new lease. Not roughly, not "it depends." The actual number. Most can't tell you. It's not in their workflow, it's rarely built into their software and it almost never appears in the reports owners get.
That's a problem, because cost per lease is one of the most useful numbers in your operation. And the few operators who track it are often calculating it in a way that makes the number look better than it is.
The formula most people use
The usual cost per lease formula is simple: total marketing spend divided by total new leases. Say you spent $60,000 on marketing last year and signed 50 new leases. That's $1,200 per lease. Sounds reasonable.
It's also a comfortable lie, because the formula leaves out one of the biggest costs of getting a resident to sign.
Concessions are an acquisition cost
Concessions live on a different line. Accounting treats them as a revenue adjustment, not a marketing expense, and people have been trained to think of them that way.
But ask what a concession is for. It's there to get someone to sign a lease. That's the definition of an acquisition cost. Giving away $2,000 in free rent to land a resident does the same job as spending $2,000 on ads to find that resident. The money just comes off a different line.
Back to the example. If you offered one month free on those 50 leases at an average rent of $2,000, that's $100,000 in concessions. Your acquisition cost isn't $60,000. It's $160,000. Your real cost per lease isn't $1,200. It's $3,200.
Here's a second example, with a bigger building. Say you have 100 units and turn 40 of them in a year. You offer two months free on each, worth $4,000 on a $2,000 unit. That's $160,000 in concessions. Add a $60,000 marketing budget and you've spent $220,000 to sign 40 leases. The math is $5,500 per lease, not $1,500.
| Standard formula | Complete formula | |
|---|---|---|
| Marketing spend | $60,000 | $60,000 |
| Concessions | not counted | $160,000 |
| New leases | 40 | 40 |
| Cost per lease | $1,500 | $5,500 |
Those are illustrative numbers, but plug in your own. You don't have to include concessions in the calculation. You just can't claim to know what it costs to fill a unit if you don't.
If you give something away to get a signature, it belongs in your cost of getting that signature.
Total cost per lease versus cost per lease by source
Once you're tracking the right number for the whole property, the next step is breaking it down by source. The overall figure is a blended average, and averages hide the differences between channels.
Say your total cost per lease, including concessions, is $4,000. Within that average, the spread can be wide. Your paid search might produce leases at $2,500 each while a listing site costs $6,000 per lease. Without a by-source view you'd never know, and you'd keep splitting the budget the same way, overspending on what doesn't work and underinvesting in what does.
Track it for every channel you use: paid search, social ads, organic search, each listing site, referrals and walk-in traffic. When one channel delivers leases at half the cost of another, shift budget toward it.
Here's what a by-source view can look like once it's running. These are made-up numbers to show the shape, not results from a property.
| Source | Spend | Concessions | New leases | Cost per lease |
|---|---|---|---|---|
| Paid search | $12,000 | $8,000 | 8 | $2,500 |
| Social ads | $6,000 | $10,000 | 4 | $4,000 |
| Listing sites | $24,000 | $42,000 | 11 | $6,000 |
| Referrals | $1,500 | $4,500 | 6 | $1,000 |
| Walk-ins and drive-by | $1,000 | $5,000 | 4 | $1,500 |
Notice what the table says. The listing sites bring in the most leases, so they look like the workhorse. They're also the most expensive way to get a signature, once you count the concessions those leads needed. Referrals bring in fewer leases, but at a fraction of the cost. A budget meeting that only looked at lease counts would miss all of it.
Be careful with small numbers. If a channel only produced three leases, one lucky or unlucky month can swing its cost a lot. Give each source a quarter or two before you make a big call.
The source view also shows you where concessions do the most damage. If your listing-site leads need the biggest concessions to convert while your paid search leads sign at asking rent, that tells you something about lead quality that no occupancy number would reveal.

How to set up the tracking
You don't need fancy software to start. You need discipline.
- Tag every lead's source at the first contact, and ask "how did you hear about us?" when it isn't automatic.
- Record the concession on every new lease, with its dollar value.
- Carry the source through to the signed lease so each lease can be matched to its channel.
- Add monthly spend by channel from your ad accounts and invoices.
- Calculate monthly, then look at the trend over a quarter, because one month of numbers is noisy.
The vacancy factor
Another cost hides in the gap between one resident leaving and the next lease starting. Every empty day is lost rent. On a $2,000 unit, a 30-day gap costs about $2,000, and a 45-day gap about $3,000.
We wouldn't fold vacancy into the main cost per lease number, because it brings in things that go beyond marketing, such as turnover timing, maintenance speed and notice periods. But we do track a second figure, cost per lease with vacancy, alongside it. It shows what resident turnover really costs.
When marketing, concessions and vacancy loss add up to $6,000 or $7,000 to replace one resident, the conversation changes. Spending another $500 per unit on marketing to shorten the vacancy window by two weeks starts to look like a bargain. It also makes the case for working on retention. See our guide to resident retention strategies for that side of it.
Common ways the number goes wrong
A few mistakes we see when owners and managers start measuring this:
- Counting renewals as new leases. Renewals don't cost what a new lease costs. Mixing them in makes the number look artificially low.
- Forgetting the unpaid marketing costs. Staff time, photography, signs and website upkeep are all part of getting a lease, even if they're not on an ad invoice.
- Using the wrong period. Spend this month, leases signed next month. For a small property, match spend to the leases it produced, and use a rolling three months to smooth the timing.
- Ignoring fees waived or deposits reduced. These are concessions too. If they helped close the lease, count them.
- Averaging across unit types. A studio and a three-bedroom don't have the same economics. Look at them separately when you can.
None of these ruins the metric. They just tilt it. Pick a consistent method, write it down and apply it the same way every month, so the trend means something.
One more thing worth saying plainly: a falling cost per lease is not always good. If it drops because you stopped marketing and let occupancy slip, you've saved nothing. Read it next to occupancy, days vacant and renewal rate, so you can tell a smarter operation from a quieter one.
What to put in front of ownership
An owner doesn't need a dashboard of twenty charts. A short monthly view usually covers it:
- Total cost per lease this month and the trailing three months.
- Cost per lease by source, with the best and worst channel called out.
- Concessions given, in dollars and as a share of new lease rent.
- Average days vacant between residents.
- One decision: where you're moving budget next month, and why.
That last line is the point. A number you don't act on is just trivia. If you're not sure what your reports should look like, our multifamily marketing team can walk through yours.
Not every lease is equal
A lease that ends early, in a skip or an eviction, or one that doesn't renew at month 12, effectively doubles your acquisition cost, because you pay to fill that unit again. If you signed 50 leases this year and 15 of those residents left early or didn't renew, your effective cost per lease is higher than the number on paper.
That's where marketing targeting meets financial performance. Better marketing doesn't just mean more leads. It means better-fit leads: people who can afford the rent without a concession and who are likely to stay. When your marketing attracts the right residents, renewal rates rise, turnover costs fall and the true cost per lease drops over time.
What changes when you track it properly
Tracking this way changes decisions in three ways.
It justifies smarter marketing spend. If your true cost per lease is $5,000, and better-targeted advertising can bring it to $3,500 by generating leads that need fewer concessions, the return is obvious. You're not spending more on marketing. You're spending less on leasing.
It gives you grounds to cut concessions. When you can show that strong demand fills units without giveaways, the conversation with ownership shifts from "everyone's offering concessions" to "our marketing produces enough demand that we don't have to." That helps NOI and value directly.
It creates accountability. When every marketing dollar traces to a lease outcome, there's no room for "we think it's working."
If you want a benchmark for the broader market, the Census Bureau publishes the national rental vacancy rate every quarter. It won't tell you your cost per lease, but it helps you judge whether the pressure you feel is local or everywhere.
Three numbers to track on every property
At Next Level Property Management, we keep three numbers for each community:
- Cost per lease by source, which shows where to put the budget.
- Total cost per lease with concessions, which shows the real acquisition cost.
- Cost per lease with vacancy, which shows the full cost of turnover.
None of these is hard to calculate. They require the right tracking, some consistency and a willingness to look at numbers you might not enjoy. Plenty of operators avoid them because the figures reveal waste.
We once sat in on a conversation where an outside consultant, a well-regarded one, was asked what cost per lease an owner should aim for. His answer was about $200. That was off by roughly a factor of ten. It wasn't a bad person giving a bad answer. It was a sign of how few people in this business have ever done the full calculation.
If you don't know your number, that's the first problem to solve. If you do know it but leave concessions out, run it again with them in. The gap between those two figures is the gap between what you think your marketing costs and what it costs. Close that gap and your decisions will improve.
Start small. Pick last quarter, pull your marketing spend and your concessions, count your new leases and do the division. It takes about twenty minutes. Then do the same by source. You'll probably find at least one channel you've been overpaying for and one you've been starving, and that single finding often pays for the whole exercise.
