Five-Year Vacancy Trends in St. Louis & St. Charles Single-Family Rentals
Over the past five years, the rental market for single-family homes in the St. Louis and St. Charles County metro areas has experienced notable shifts in vacancy rates. These changes – from pre-2020 lows, through the pandemic upheaval, to recent corrections – have impacted rent prices, time on market, tenant quality, and prompted landlords to adjust their strategies.
This post dives into specific vacancy rate trends in both counties, visualizes how those rates have changed, and breaks down how it affects local landlords and real estate investors. We'll also highlight municipalities like O'Fallon, Florissant, Wentzville, and St. Peters and provide key resources to help you navigate the local rental market successfully.
Vacancy Rate Trends in St. Louis & St. Charles (2019–2024)
In St. Louis County, vacancy dropped from nearly 10% in 2013 to about 4.5% by 2019. St. Charles County followed a similar trend, dropping below 6% in 2019. The pandemic in 2020 pushed occupancy even higher as families sought space and stability.
In 2020, the St. Louis metro rental vacancy rate dropped to 5.3%, the lowest in years. St. Louis County likely saw rates closer to 3–4%. St. Charles had a small bump in 2021 (8.2%) as new construction entered the market but returned to around 5–6% by 2023.
As of 2023, the metro-wide vacancy rate climbed back to 7.73%, the highest since 2019 but still reasonable compared to historical norms.

Municipality Highlights
- Florissant – Affordable suburb with consistent renter demand.
- O’Fallon – Booming St. Charles suburb with new SFR development.
- St. Peters – High demand from families and professionals.
- Wentzville – Fastest-growing city in Missouri, strong rental absorption.
Impact on Rent Prices and Time on Market
As vacancies dropped, rents climbed. By 2019, St. Charles median rent exceeded $1,050. Across the metro in 2024, it’s around $1,225.
Homes are leasing quickly — average 22 days on market. In tight markets, tenant quality increases, and landlords can screen more strictly. As vacancy rises, landlords may need to be a bit more flexible.
Tenant Quality and Turnover
Low vacancy improves tenant quality due to increased competition. Landlords can be more selective and experience higher renewal rates. In higher-vacancy markets, more flexibility may be needed in screening, but retention remains key to minimizing costs.

Five-Year Vacancy Trends in St. Louis & St. Charles Single-Family Rentals
Over the past five years, the rental market for single-family homes in the St. Louis and St. Charles County metro areas has experienced notable shifts in vacancy rates. These changes – from pre-2020 lows, through the pandemic upheaval, to recent corrections – have impacted rent prices, time on market, tenant quality, and prompted landlords to adjust their strategies. In this post, we’ll dive into specific vacancy rate trends in both counties, visualize how those rates have changed, and discuss what it all means for local landlords and real estate investors. We’ll also highlight key municipal hotspots (like O’Fallon, Florissant, Wentzville, and St. Peters) and provide resources (investor associations, REALTOR® data, city housing links) to help landlords navigate the current landscape.
Vacancy Rate Trends in St. Louis & St. Charles (2019–2024)
Vacancy rates – the percentage of rental homes that are vacant and available – hit historic lows in the late 2010s, then swung sharply during 2020-2021, and have since risen to more typical levels. In St. Louis County, the rental vacancy rate peaked around 9.9% in 2013 and then steadily declined to only ~4.5% by 2019 , indicating a tight market. St. Charles County saw a similar drop: after spiking near 9.9% in 2016, vacancy fell to about 5.99% in 2019 . These late-2010s rates were quite low historically, reflecting that single-family rentals were in high demand and few were sitting empty.
Then came 2020. During the early pandemic, many local landlords observed an unprecedented surge in occupancy – people were staying put or seeking single-family homes (for more space) in the suburbs. The overall St. Louis metro rental vacancy rate plunged to around 5.3% in 2020, the lowest level in years (down from about 8.8% in 2019) . In practical terms, this meant most decent rental houses were getting snapped up quickly, and very few were languishing without tenants. St. Louis County in particular may have seen vacancy drop into the 3–4% range by 2020-21, an extremely tight condition . By contrast, fast-growing St. Charles County experienced a brief spike around 2021 (ACS data showed roughly 8.2% rental vacancy in St. Charles in 2021 ), likely due to new housing construction coming online and some pandemic-related shuffles. Even so, that inventory was soon absorbed as demand remained strong.
Starting in 2022 and into 2023, vacancy rates began creeping back up toward more balanced levels. The latest Census Bureau data shows the St. Louis metro’s average rental vacancy rate hit 7.73% in 2023, an increase of over a full percentage point from the prior year . This 2023 rate was the highest in four years, though still moderate by historical standards (for context, a decade ago vacancies were often above 9–10%). St. Louis County’s vacancy inched back toward the mid-single-digits, and St. Charles County’s vacancy settled roughly in the 5–6% range by 2023 (down from that 2021 bump). In short, after the rollercoaster of 2020 (plunging vacancies) and 2021 (rebounding vacancies), the market in both counties is now closer to equilibrium – not as ultra-tight as 2020, but still tighter than the early 2010s era.
To visualize these swings, consider the St. Louis metro’s vacancy trend over the past several years. The chart below (based on U.S. Census data) illustrates how vacancies declined into 2018–2019, bottomed out in 2020, and then rose through 2023:

Figure: St. Louis MSA Rental Vacancy Rate, 2015–2023. After a low of ~5.3% in 2020, vacancy climbed to 7.7% by 2023 .
These vacancy dynamics underline just how unusual the COVID-19 period was. High occupancy (low vacancy) in 2020 was driven by factors like eviction moratoriums (keeping tenants in place) and a shift toward single-family living. By 2022–2023, as life normalized, more rentals opened up again – some new construction, some turnover that had been delayed – causing vacancy rates to rise.
It’s worth noting that single-family rentals have become a major part of the local rental supply. In fact, in the St. Louis suburban submarkets, a large share of renters now live in houses rather than apartments. For example, in the western St. Louis area, 38% of renter households were in single-family homes as of 2016, up from 25% in 2000 . This trend has only continued, meaning the vacancy rates discussed here are heavily influenced by what’s happening in the house rental market (not just big apartment complexes).
Local Spotlights: In St. Charles County, rapidly growing communities such as O’Fallon , St. Peters , and Wentzvillehave seen an influx of newly built homes (some specifically intended as rentals). This growth initially added some vacancy as new units awaited tenants, but strong population gains quickly filled many of these homes. (St. Charles County has been a regional leader in new home construction – over 40% of new home demand in the metro was projected to be in St. Charles a few years ago .) Meanwhile, in St. Louis County, established municipalities like Florissant (an affordable North County suburb) continue to enjoy steady renter demand for single-family houses. These communities have relatively affordable home prices and rents, which helps keep occupancy high as many families opt to rent there rather than in costlier areas. Overall, both counties’ most popular cities benefit from local amenities and schools that attract long-term renters, keeping vacancies relatively low.
Impact on Rent Prices and Time on Market
Shifts in vacancy rates have a direct impact on rent prices in the St. Louis/St. Charles region. When vacancies plunged in 2019–2020, landlords gained pricing power – fewer empty homes meant less competition and more applicants per property. Even before the pandemic, tight supply was nudging rents upward. For instance, in St. Charles County the median gross rent hit $1,057 by 2019 – the highest on record at that time . Similarly, St. Louis County saw rent growth through the late 2010s (median rents there peaked just above $980 in 2017 in real terms) .
During 2020–2021’s very low vacancy period, many landlords were able to raise rents more aggressively, and new lease offers often came in at premium rates. Renters were competing for a limited number of single-family homes, which drove annual rent increases above normal levels. By 2022 and 2023, as vacancy rates rose a bit, rent growth began to moderate. Recent market data show that while rents are still increasing, the pace has slowed. The median rent across the St. Louis metro is around $1,225 as of early 2024, but rent growth has started to decelerate in line with broader economic conditions . In other words, landlords aren’t able to hike rents quite as steeply as they could when vacancies were at rock bottom. (Many tenants are more price-sensitive now, and with a few more options on the market, exorbitant rent increases may lead renters to look elsewhere.) Still, overall rent levels today are higher than five years ago – a reflection of the strong demand and limited supply that persisted through most of this period.
Vacancy swings have also affected how long rental homes sit on the market. In times of low vacancy (high demand), houses rent out fast. Landlords often report that a well-priced, well-presented single-family home in the region can find a tenant within a few weeks. Currently, properties in the St. Louis area rent remarkably quickly – averaging around 22 days on the market before going under contract . That’s only about three weeks from listing to signing a lease. Such short market times indicate a persistent tenant demand, even as vacancy rates have ticked up slightly. By contrast, if vacancy were to rise further into the high single-digits or above, we’d expect the average time on market to lengthen. In a softer market, a rental home might take a month or two (or more) to find a tenant, and landlords might have to relist or adjust pricing to avoid prolonged vacancy.
So far, St. Louis and St. Charles single-family rentals are leasing briskly. Quick turnaround times have a few implications for landlords: (1) you must be ready to show the property and process applications immediately when a tenant gives notice, because qualified renters are acting fast; and (2) you can be reasonably confident that if your home is in good condition and priced close to market, it won’t remain vacant for long. The current ~7.5% regional vacancy rate is still low enough that demand outstrips supply in many neighborhoods .
Tenant Quality and Turnover Considerations
One often overlooked effect of vacancy rate changes is on tenant quality and turnover. When vacancy rates are extremely low (landlord’s market), landlords receive more rental applications for each available home. This larger tenant pool allows for high selectivity – landlords can screen for excellent credit, stable employment, and clean rental history, and still fill the unit easily. Many local landlords took advantage of the 2020-2021 tight market to raise their screening standards, knowing another eager renter was waiting if the first prospect didn’t qualify. The result was often higher-quality tenants: renters who are financially stable and likely to take care of the home. This can lead to lower default risk and less property damage, ultimately saving the landlord money.
Additionally, in a low-vacancy environment, tenants are more motivated to renew leases, since finding another rental (especially a single-family home in the same area) might be difficult or costly. Landlords in St. Louis/St. Charles with good tenants have been smart to prioritize renewals and avoid turnover. Renewing a lease with a modest rent increase (rather than risking a vacancy) is a common strategy when you know you have a solid tenant in place. This keeps turnover costs down (no need to advertise, clean, and repair between tenants) and maintains steady income.
On the other hand, as vacancy rates rise, the dynamic can shift. If the market softens and renters have more choices, landlords might see fewer applicants per listing and may have to relax their criteria slightly to get units occupied. For example, a marginal applicant who might have been passed over a year ago could be given more consideration if they’re the only one in line. Landlords should be cautious here – a higher vacancy rate doesn’t necessarily mean you should rent to an unqualified tenant (that can lead to eviction or damage costs later), but it might mean being a bit more flexible on requirements (perhaps accepting a lower credit score with a larger deposit, for instance). The key is to balance filling the vacancy in a reasonable time with maintaining reliable tenants. Fortunately, the current vacancy levels are still low enough that most landlords can find quality tenants without much delay.
In short, tenant quality tends to track vacancy: tighter markets yield highly qualified renters (since landlords can choose the best of many), whereas looser markets might force some compromise on tenant selection. Being aware of where we are on that spectrum (today we’re in a relatively balanced market) can help you adjust your screening strategyaccordingly. No matter the market, proactive landlords focus on tenant retention – keeping good renters happy so they renew – as the first line of defense against high vacancy. Simple efforts like responding promptly to maintenance requests, performing preventative upkeep, and considering reasonable lease renewal incentives (e.g. minor upgrades or not raising rent one year) can pay off in longer tenancies and fewer vacant periods.
Landlord Strategies for an Evolving Market
Given these vacancy trends and their effects, what strategies should landlords and investors employ in the St. Louis and St. Charles single-family rental market? Below are several practical approaches:
Stay Informed on Local Market Data: Knowledge is power. Track vacancy and rent trends via trusted sources – for example, the St. Louis REALTORS® Association releases housing reports, and the Missouri REALTORS®provide statewide market stats and resources . Knowing that, say, “rents are up 3% year-on-year in St. Charles” or “vacancy is rising in North County this quarter” can guide your decisions on setting rent or when to invest in a new property. (See Resources at the end of this post for links.)
Set Competitive Rent Prices: In a high-vacancy situation, overpriced rentals will sit vacant. Even in today’s balanced market, savvy tenants have access to online listings and will skip over a house that doesn’t match the area’s price range. Compare similar listings in your neighborhood and be realistic. If the vacancy rate creeps up in your area, consider pricing just below the market median to attract a bigger pool of applicants and rent the home faster. Conversely, when vacancy is ultra-low, you might aim slightly above market – but be cautious, as an empty month can quickly wipe out the gain from a higher rent. The rule of thumb is to minimize downtime. A modest rent concession is often worth it to get someone in the home sooner.
Enhance Marketing and Curb Appeal: As vacancy rates inch up, you’ll want your rental to stand out. Professional photos, online listings on multiple platforms, and prompt responses to inquiries are essential. Also, curb appeal and maintenance matter more when renters have options – a well-kept property will attract quality tenants more quickly. Small investments (fresh paint, landscaping, fixing that broken gutter) can pay off with shorter vacancies. In tight markets you might rent “as-is” in a rush, but in competitive times, addressing deferred maintenance before listing is wise.
Streamline the Turnover Process: Every day a property sits vacant is lost income. Have a plan for quick turnovers: line up contractors or cleaners in advance if you know a tenant is leaving, and start advertising before the unit is vacant if possible (with the current tenant’s permission). In many St. Louis area municipalities, you’ll also need to schedule an occupancy inspection whenever a tenant moves out. Build that into your timeline – for instance, Florissant and most North County cities require a passed inspection and occupancy permit for the new tenant , which can take several days. The City of St. Louis has a similar Housing Conservation Inspection requirement for rental units . Being on top of these local rules (and getting the paperwork done quickly through the city’s public works or building department) will reduce the idle time between tenants.
Focus on Tenant Retention: As mentioned, keeping good renters is far easier than finding new ones. Especially now, with vacancy rates around 7%, there’s a bit more incentive for tenants to shop around at lease end. Proactively reach out 2–3 months before lease expiration. If you have a reliable tenant, consider offering a lease renewal with a reasonable rent increase (or even no increase if that fits your financials) to lock them in for another year. Perhaps offer a minor upgrade (e.g. new carpet, or a professional deep clean) as a thank-you for renewing. Such gestures can increase loyalty. High turnover is costly – not only do you risk an empty house, but you also incur repainting, cleaning, and advertising costs. Many successful single-family landlords in St. Louis aim for longer-term tenancies to maximize cash flow.
Adjust Tenant Screening (Carefully): When the market was hyper-competitive, many landlords had the luxury of extremely strict screening (income 3x rent, 700+ credit score, etc.). If you’re now in a sub-market or time where you’re not getting applications as quickly (say your property has been listed for a month with few inquiries), you might revisit your criteria. This doesn’t mean renting to blatantly unqualified tenants – rather, consider factors like: maybe accept a pet with a pet fee (many families have pets, and you widen your audience by being pet-friendly), or consider a slightly lower credit score if job/income is solid (perhaps offset by a higher security deposit). The goal is to widen your pool just enough to get a good tenant in, without exposing yourself to undue risk. It’s a balancing act – one that becomes important if vacancy rates rise. In contrast, when units are flying off the market in days, stick to your strict criteria; you’ll likely find a tenant who meets them.
Be Prepared for Economic Changes: Both St. Louis City and County have relatively affordable rents compared to coasts, but local economic shifts (like major employers expanding or leaving) can affect housing demand. Stay attuned to news (business developments, interest rate changes, etc.) that might influence local rental demand. For example, if mortgage rates are high, more people may choose to rent longer, bolstering demand for your rental home. If a new company opens in O’Fallon or Chesterfield, you might see an uptick in renters relocating for jobs. These factors can indirectly influence vacancy rates and how much you can charge. Being proactive – maybe you decide to buy another rental property when you see demand rising, or conversely hold off if you sense the market is cooling – can put you ahead of the curve.
Leverage Local Networks and Resources: Don’t go it alone. Tap into the community of landlords and investors in the area. The St. Louis Real Estate Investors Association (STLREIA) is a great example – they host monthly meetups, share market insights, and provide education for landlords and investors . Networking with peers can alert you to neighborhood-specific trends (e.g., “lots of rentals coming on the market in XYZ suburb”) and also hook you up with trusted contractors, attorneys, or property managers. Similarly, keep an eye on communications from Missouri REALTORS® and St. Louis REALTORS®; even though they cater to real estate agents, they often publish housing market updates and forecasts that savvy landlords can use. In a profession where local knowledge is key, these networks and data sources are invaluable.
Finally, always ensure you’re legally compliant with local ordinances. Different municipalities in St. Louis County have different rental rules – some require landlord licenses or regular inspections. For instance, St. Louis City provides an online Landlord’s Guide (Inforent) with guidance on permits, tenant screening, lead paint disclosures, and more . Staying on top of these requirements not only keeps you out of trouble but also helps maintain good tenant relations (tenants appreciate a landlord who takes care of safety and legalities). When vacancy rates fluctuate, the last thing you want is a preventable delay (like failing an occupancy inspection) causing additional lost rent.
Resources for Local Landlords
To further educate yourself and stay connected in the St. Louis/St. Charles rental market, here are some helpful resourcesand links:
St. Louis Real Estate Investors Association (STLREIA) – A non-profit organization dedicated to educating and networking local real estate investors and landlords. They host meet-ups, have an active online community, and share tips specific to the St. Louis market. Joining STLREIA can put you in touch with experienced landlords who have navigated many market cycles . (Website: STLREIA.com)
Missouri REALTORS® – The state REALTORS® association provides market statistics, legislative updates, and resources that can benefit landlords (even if you’re not an agent). They track housing trends statewide and often publish insights on inventory, vacancy, and property management best practices. Missouri REALTORS® also advocates for property owners’ rights at the state level . (Website: missourirealtor.org)
Local City Housing Departments: Most cities in St. Louis County and St. Charles County have webpages for landlord requirements and housing resources. For example, the City of St. Louis Housing Division offers an online guide called Inforent: A Landlord’s Guide with information on occupancy permits, tenant screening, and eviction procedures . Similarly, St. Louis County’s Neighborhood Preservation department can assist with codes and permits, and many municipalities (like Florissant or O’Fallon) list their rental property ordinances on their official websites. Always check your property’s city website for a “Landlord Information” or “Rental Property Owners” section. (See official city websites: e.g., Florissant, MO , O’Fallon, MO , Wentzville, MO , St. Peters, MO .)
St. Louis & St. Charles County Housing Authorities: If you’re interested in the Section 8 program or other rental assistance programs (which can be a strategy for reducing vacancy, as you tap into a pre-qualified pool of tenants), the housing authorities can be a resource. The Housing Authority of St. Louis County provides a Landlord Portal and liaison for those renting to voucher holders . Likewise, the St. Charles County housing assistance programscan be accessed via the county’s community development department. These agencies often host briefings for new landlords and ensure you understand the inspection and leasing process for assisted tenants.
Landlord-Tenant Law Guide (Missouri Attorney General’s Office): Missouri has specific laws governing security deposits, evictions, habitability, etc. St. Louis County’s website hosts a PDF of Missouri’s Landlord-Tenant Law which is a must-read for all landlords . It covers your legal obligations and tenants’ rights in areas such as required notices, return of deposit timelines, and property maintenance. Staying compliant with these laws not only avoids legal trouble but also makes for better landlord-tenant relationships. (Resource: “[Missouri Landlord-Tenant Law ](https://ago.mo.gov/docs/default-source/publications/landlord-tenant-law.pdf)” – a handbook from the Missouri Attorney General.)
St. Louis Real Estate News & Blogs: Keep an eye on local real estate news sites (like St. Louis Real Estate Newsby local analyst Dennis Norman). They frequently analyze Census data and market trends. For instance, reports on 2023 vacancy rates hitting a four-year high or updates on homeownership rates can give context to the rental market. These can be found via local real estate blogs or the business section of the St. Louis Post-Dispatch. They help you stay updated beyond just your own properties.
By leveraging these resources, you can stay educated and make proactive decisions about your rental investments. The St. Louis and St. Charles single-family rental market has proven resilient and profitable for landlords who adapt to its ebbs and flows. As vacancy rates trend and economic conditions change, being well-informed will position you to minimize vacancies, set the right rents, attract great tenants, and ultimately maximize your returns in the long run.
Conclusion: The past five years have been anything but static for landlords in St. Louis and St. Charles counties – we’ve seen vacancy rates fall to the floor, then bounce back up to a sustainable level. Through it all, single-family rentals remain in demand, and opportunities abound for attentive landlords. By understanding vacancy trends and their ripple effects on rent, marketing, and tenant management, you can stay ahead of the curve. Whether you own a bungalow in Florissant or a new two-story in O’Fallon, the fundamental strategy is the same: keep your properties desirable and well-priced, treat your tenants well, and plug into the local real estate community for support. With that approach, you’ll navigate the ups and downs of the market and come out on top, enjoying steady income from your long-term rentals in the vibrant St. Louis region.
