Multifamily marketing in Southern California has gotten harder, and the numbers explain why. Vacancy has climbed past 5%, new supply keeps delivering, and roughly a third of properties are dangling concessions just to fill units. Formula Marketing is a San Diego agency that runs lease-up and stabilized-asset campaigns for apartment communities across the region — and the AMLI Aero launch is a working example of what that takes. When the market tightens, marketing stops being a line item and becomes the difference between an absorbed building and a bleeding one.
The Southern California leasing market right now
The easy-money era is over. San Diego multifamily vacancy has risen to roughly 5.7%, well off the 2.6% lows of 2021, according to Matthews Real Estate Investment Services market data. More than 6,200 units delivered in 2025, with thousands more on the way, so new communities are fighting for the same renters.
That competition shows up as concessions. With about 30% of properties offering move-in incentives, discounting alone won’t differentiate you — every building down the street is doing it. The communities that lease faster are the ones renters actually find and remember first. A discount gets attention for a week; a strong, visible brand keeps a property top of mind through an entire decision cycle that can stretch for months.
Lease-up marketing starts before the leasing office opens
A successful lease-up builds demand months ahead of move-in. By the time the doors open, there should already be a waitlist of qualified prospects who know the brand, the neighborhood story, and the floor plans. That only happens if the marketing engine was running during construction.
This is the approach behind our AMLI Aero lease-up work — brand identity, a conversion-focused website, paid demand generation, and a content plan that gives the property a personality before there’s anything to tour. The pre-leasing pipeline is what protects you from a slow, expensive opening.
Generate demand where renters actually search
Renters in Southern California start on their phones — Google, Apartments.com, Instagram, and increasingly AI assistants. A property that isn’t visible across those channels simply doesn’t enter the consideration set. Paid search and paid social do the heavy lifting during lease-up because they put units in front of renters at the moment of intent.
The catch is targeting. Broad campaigns burn budget on people who’ll never sign. Tight paid advertising aimed at the right income, radius, and life stage drives qualified tours, not just clicks — and tours are what fill buildings.

Brand and story beat a concession war
When every community offers a month free, price stops being a differentiator. What renters actually choose is a place they can picture living. The communities that win on something other than discount build a real identity — a name, a look, a neighborhood narrative that feels like a lifestyle, not a spreadsheet.
That’s why branding and content marketing aren’t extras in a lease-up. They’re the reason a renter tours your property first and signs before they shop the building next door on incentives alone. In a market this crowded, the building that owns the story usually owns the lease.
Your website is the leasing office that never closes
Most renters decide whether to tour based on your site, not a phone call. If the floor plans are buried, the pricing is hidden, or the booking flow is clunky on mobile, you lose the lead before a leasing agent ever speaks to them. A fast, clear, tour-driving website is the highest-leverage asset in any lease-up.
We build property sites designed around one action — booking a tour — with the kind of web development that loads fast and converts on a phone. Everything else in the campaign points back to it.
Measure absorption, not vanity metrics
In multifamily, the only metrics that matter trace to signed leases: cost per tour, tour-to-lease rate, and absorption pace against pro forma. Impressions and likes don’t pay the construction loan. The National Multifamily Housing Council tracks the broader demand picture, but your dashboard should track the funnel that ends in a signature.
Tying spend to absorption is also how we know when to shift budget. With predictive analytics, we can see which channels produce real tours and move dollars there mid-campaign instead of waiting for a quarterly report. That kind of mid-flight correction is often what keeps absorption on pace when a new competitor opens nearby.
Frequently asked questions
When should multifamily lease-up marketing begin?
Three to six months before move-in, ideally during construction. Pre-leasing demand is what prevents a slow opening, and it can’t be built overnight once the doors are open.
How do I compete without slashing rent?
Build a brand and story renters connect with, and be the most visible community in the search results. Identity and discoverability let you win tours without leading with the deepest concession.
What does multifamily marketing cost in Southern California?
It scales with unit count and lease-up timeline. Concentrated demand generation during the pre-leasing and opening window typically delivers the strongest return, rather than thin year-round spend.
Do apartment communities really need AI and analytics?
Yes. Renters research through AI assistants now, and analytics let you move budget toward the channels producing real tours instead of guessing. Both shorten the path to stabilization.
