ILS vs. paid search: where your lease-up budget actually works smarter, not harder

Sep 03, 2026 8 min

Imagine a daily commuter who found a shortcut years ago and still takes it every morning, even though everyone started taking it and the traffic got busier and busier. Fast-forward to today: the shortcut adds more time to the commute every single day, and that daily commuter never realized it.

Multifamily ad budgets run on the same muscle memory. Ask five owners how their lease-up spend is split between ILS listings and paid search, and four of them will give you a number that has nothing to do with performance. It's the Diamond package on Apartments.com, the PMAX campaign from the last agency, or what the pro forma assumed eighteen months ago. It's a real set-it-and-forget-it mindset, but the performance data says otherwise. Once you see the gap, you can run the same math on your own budget in about 10 minutes.

Here's the toll on that shortcut: according to a recent RentCafe study, paid search converts a lead to a signed lease at 15.44%. According to a recent Apartments.com study, ILS does it at 2.37%. Put those two numbers side by side, and paid search is closing at roughly 6.5x the rate (our math, from the figures above), often at a lower cost per lease. 

So it's worth asking yourself: are ILS the shortcut adding time to your stabilization goals?

Visibility gets you noticed; intent gets you leased

An ILS listing puts your community in front of someone who's still window-shopping, comparing five buildings across three neighborhoods with a dozen tabs open. Paid search puts you in front of someone who already typed "2 bed apartment Tennyson, Denver" into Google, because they've stopped shopping and started deciding. One of those two people is closer to a lease. The budget alone can't possibly tell you which one.

Here's how the drift happens: a budget gets set once and left alone, and it almost always tips toward whichever channel was easiest to turn on, which is ILS, because listing platforms make it frictionless: pay, publish, done. Paid search takes serious expertise, setup, and weekly attention, so it gets the budgetary leftovers even though it converts far better once someone's actually watching it.

The mix should also move with the property, not sit still. A new development with no listing history needs ILS and broad visibility to build awareness, because search demand isn't high enough yet for paid search to catch. A stabilized property with an established reputation can lean harder into the high-intent searches happening for its name and its competitors. Neither one is wrong. They're answering different questions at different points in the property's life.

The part a dashboard can't do

That strategy is informed by 13+ years of marketing properties at every stage, and most of what actually moves the numbers doesn't live in an ad account. It lives in what the leasing team hears on tours, which lead sources are quietly producing no-shows, and patterns nobody notices until someone's looking for them. So we stay close to leasing teams on purpose. Feedback, lead quality, conversion trends, and everything else happening around the campaign shape where the money goes next, not just what a dashboard says happened last month.

“Some operators want AI - set it and forget it. A lower price point, less involvement. I understand the appeal, especially when budgets are tight and patience is thin. What they gain in simplicity they give up in precision. We’re betting on the other side of that... The human touch is, ironically, the new differentiator, and we’re all in on that.”

- Chris Arnold, Co-Founder at Authentic

What we actually do about it

Most in-house teams and self-managed agency relationships struggle to staff this, not because the talent isn't there, but because checking channel performance every Monday morning for every property in the portfolio rarely (if ever) fits into a leasing team's existing job description.

That's what our Multifamily Property Audit fixes first: a no-fluff diagnostic of your leasing performance, website, paid media, and comp set, with a prioritized action plan on what to fix first, starting at $5K over a three-week engagement. The Audit also scopes the next move, not a sales pretext for one.

If the finding is a channel mix that needs a hand on the wheel, Demand-to-Door runs it on an ongoing basis: paid media, ILS optimization, email nurture, reputation management, and website optimization, coordinated directly with your leasing team, starting at $990/month.

If the finding is a website that isn't converting the traffic it's already getting, the Digital Conversion Accelerator picks up right where the Audit leaves off: a custom Amplify website paired with digital collateral and six months of full-service D2D, one integrated push to turn that traffic into signed leases, starting at $45k for a six-month engagement.

Where should you spend smarter: ILS vs. paid search

We're not saying ILS is a waste, because we know it's not. ILS listings are essential to compete in today's competitive lease-up landscape. Still, their premium package typically isn't the smartest use of your ad-spend budget, unless your KPIs are impressions and reviews you can't respond to. 

The takeaway: it depends on where the property sits in its lifecycle and where your real cost per lease falls, not on some fixed industry ratio. Paid search deserves more of the marginal dollar than habit usually hands it. Keep ILS in the mix; about 70% of communities use one, and renters still start there. The exact split is worth calculating from your own numbers, not guessing from a published range.

Back to that shortcut

Shortcuts only work if someone keeps checking that they still do.

Your commute doesn't get that check from an ILS. You drive the same route every morning on autopilot, assuming it's still the fastest way, even when you know you have other options. 

Paid ads work the same way. Most owners set a budget, launch the campaign, and never look back.

The fix: work with someone who keeps checking. A seasoned multifamily marketing partner like your friends at Authentic treats every channel like it has to keep earning its spot, not just the one it earned on day one.

Because a few extra minutes on the drive don't feel like much on any given morning, stack them across a full lease-up, and you've lost the quarter. Meanwhile, the property down the street, run by someone who ditched the shortcut months ago, is already leasing ahead of you.
