Every property manager knows leasing slows down after Labor Day. Fewer people move in November, almost nobody moves between Christmas and mid-January, and a unit that leased in nine days in June can sit for six weeks in December. What most companies do about it is discount. What actually works is changing when your units come available in the first place, and making the website do more work per visitor while there are fewer of them.
Last winter was worse than a normal winter
RealPage counted roughly 40,400 units of net move-outs across the professionally managed apartment stock in the fourth quarter of 2025. That was the first seasonal decline in demand in three years, and it pulled occupancy down to 94.8 percent, 60 basis points off the prior quarter. Asking rents fell 1.7 percent over those three months, which RealPage described as about twice as deep as the fourth-quarter cuts the market had made in the previous five years. Across the full year, rents finished down 0.6 percent, the deepest annual price decline since early 2021.
Read that sequence carefully, because it describes a specific failure. Operators went into the slow season with occupancy they did not want to lose, discovered that the usual November traffic did not arrive, and cut price to hold the units they had. Everybody cut at the same time, so nobody gained share, and the whole market reset lower going into 2026. The cost of that was not one slow quarter. It was the rent roll every one of those leases locked in for the following twelve months.
This year the slow season starts from a softer base
The Census Bureau put the national rental vacancy rate at 7.3 percent in the second quarter of 2026, in figures released on July 28. Apartment List has its national vacancy index at 7.2 percent, having peaked at 7.3 percent in February, the highest reading since it began tracking occupancy in 2017. The national median rent sits at $1,388 and rose 0.2 percent in July, a sixth consecutive monthly increase, but is still down 1.1 percent against a year ago. Units are taking an average of 30 days to lease after being listed, and that is the summer number.
The clearest signal is what landlords are already paying to fill units during the good months. Zillow reported that 39.7 percent of rentals on its platform advertised a concession in June, up from 35.2 percent a year earlier, against a typical asking rent of $1,965. In the metros that absorbed the most new construction the share is far higher: 67.1 percent in Charlotte, 65.9 percent in Denver, 64.6 percent in Dallas, 64.3 percent in Austin, 64.2 percent in Salt Lake City. San Francisco, where supply never arrived, sits at 24.9 percent. If two out of three listings in your market are already giving away a free month in June, a free month in January is not a lever. It is table stakes.

Do the concession math before you offer one
A free month on a twelve-month lease costs 8.3 percent of the year's rent. On the national median of $1,388 that is $1,388 given away, and it is given away permanently, because the renewal conversation next year starts from whatever number is printed on the lease. Cutting the asking rent by $100 a month costs $1,200 over the same year and does the same damage to the renewal. Meanwhile, each week a unit sits empty at that rent costs about $324.
So the arithmetic is straightforward. A concession is worth offering when it genuinely shortens the vacancy by more than about four weeks. It is worth nothing when it simply funds a lease you were going to sign anyway, which is what happens when the concession is the only thing you changed. The unit that sat for six weeks in December usually did not sit because the price was wrong. It sat because forty percent fewer people were looking, the listing had no interior photos, the available date said "now" when it had said "now" since October, and nobody answered the Saturday inquiry until Monday.
| What changes in the off season | What it does to your numbers | What to change on the site |
|---|---|---|
| Fewer searchers | Traffic falls, so conversion rate per visitor decides the month | Price, available date and concession terms visible on the listing itself, not behind a call |
| Longer time on market | Listings go stale and lose ranking in the portals | Refresh photos and copy every two weeks rather than relisting the same asset |
| Concessions everywhere | Your offer stops being a differentiator and becomes the baseline | State the exact terms and the deadline. A dated offer converts, an open-ended one does not |
| Dark by five o'clock | Weekday evening showings stop working, so tours compress into two weekend days | Self-guided tour booking, plus a walkthrough video shot in daylight for everyone else |
| Renewal season | Every non-renewal becomes a vacancy in the worst possible month | Renewal offers and payment history in the resident portal, sent 90 days out |
The lever almost nobody pulls: lease-term engineering
Here is the part that compounds. If a unit turns over in November and you sign a standard twelve-month lease, that unit now expires every November for as long as you manage it. You have not solved an off-season vacancy. You have scheduled one, annually, forever. Multiply that across a portfolio where turns happen whenever they happen, and a predictable share of your doors is permanently locked into the worst leasing weeks of the year.
The fix is to price the term, not only the rent. A unit available in November gets offered at ten months, fourteen months, or eighteen months, so the expiration lands between May and August when demand is at its peak. The one-time cost is small, sometimes nothing, and it converts an annual problem into a single event. Large operators have run term-based pricing for years through their revenue management systems. Independent managers rarely do it, usually because the website only ever shows one term.
Two things make this safe to run. Publish the term options and their pricing on the listing page so every applicant sees the same menu, and set the rule by unit and by availability date rather than deciding case by case at the counter. Consistent, published, date-driven pricing is both easier to defend and easier to explain to an owner who wants to know why their unit was offered at fourteen months.
Winter rewards the boring website
In peak season a mediocre listing page still leases units, because there are enough renters that somebody will tolerate it. In January there is no volume to hide behind. The people searching in the middle of winter are usually moving for a reason they cannot postpone, a job start, a lease ending, a relationship changing, and they are decisive when they find something that answers their questions. They are also comparing you against listings that publish a price, a floor plan, an available date and a concession deadline, because those listings exist in every market now.
So the off-season work is unglamorous. Photograph the unit in daylight while there still is daylight in October. Write the available date as an actual date. Put the concession terms in plain words with an expiry. Make it possible to book a tour without a phone call, because a renter looking at listings at nine on a Tuesday night in December cannot call you. None of that is a campaign. All of it is why one company's units lease in the slow months and the company down the road spends December cutting rent.
The seven-step off-season plan
Pull your lease expiration calendar for the next 12 months
Count how many leases expire between November and February. That number is your off-season exposure, and it is the only figure on this list you can change a year ahead of time.
Price the term, not just the rent
Offer 10, 14 or 18-month leases on anything turning in the fall so the next expiration lands in peak season. Publish the options and their pricing on the listing page rather than negotiating them individually.
Start renewals 90 days out
A renewal you keep is a vacancy you never have to fill in January. Send the offer through the resident portal with the payment and maintenance history attached, and follow it with a call rather than waiting for a reply.
Shoot photos and video before the clocks change
Daylight interior photos and one walkthrough video per floor plan, captured in October, carry the listing through four months of grey weather. Reshooting a dark unit in January is not the same asset.
Make the offer specific and dated
Half a month free on a 14-month lease signed by 15 December beats "move-in specials available" in every measurable way. An open-ended concession reads as a permanent discount, which is exactly how the renter will treat it at renewal.
Open up touring after dark
Self-guided access or lockbox tours with a booking link, plus weekend slots on the calendar. Weekday evening showings quietly stop working in November and most teams never adjust for it.
Judge marketing on leases per lead, not on traffic
Sessions will fall between November and February no matter what you do. Track leads per listing, tours booked per lead, and days on market instead, so a normal seasonal traffic drop does not get diagnosed as a marketing failure.
The bottom line
The slow season is not a surprise and it is not a marketing problem. Last winter the market lost 40,400 units of net demand in a single quarter and cut rents twice as hard as it usually does in the fourth quarter, and this one starts with vacancy near a record and two in five listings already advertising a concession. Discounting into that is how you end up with a lower rent roll for the whole of next year. The work that pays is done now, in August and September: count the leases expiring in the dead months, offer terms that move those expirations into May through August, take the photographs while the light is good, and make sure a renter searching at nine at night in December can see the price, the date and the offer without calling anybody. The units still lease in winter. They just lease for the companies that prepared for it.
