If you are thinking about buying a rental property in Brentwood, you are probably asking the right first question: will the numbers and demand support the investment? That matters even more in a close-in suburb where purchase prices can be higher than some other parts of St. Louis County. The good news is that Brentwood shows several signs of steady rental demand, especially from smaller households and commuters. Here is what to look at before you buy, and where the best opportunities may be.
Brentwood Rental Market Overview
Brentwood looks less like a bargain cash-flow market and more like a stable, higher-income rental niche. According to U.S. Census QuickFacts for Brentwood, the city had an estimated population of 8,111 in July 2024, a median household income of $99,719, and a median gross rent of $1,439.
That rent level stands above the St. Louis County median gross rent of $1,209, which suggests Brentwood sits at a stronger price point for rentals than the county overall. The same Census source reports an owner-occupied housing unit rate of 63.0%, meaning renters still make up a meaningful share of the local housing market.
Why Brentwood Draws Renters
Location is one of Brentwood's biggest strengths. The city says it offers easy access to I-64, I-170, and I-44, and is just minutes from downtown St. Louis, while also supporting a broad business base with more than 630 businesses, according to the City of Brentwood's business site information.
For renters, that kind of access can make daily life easier. Short commutes, nearby jobs, and access to shopping and services often help support steady tenant demand in inner-ring suburbs like Brentwood.
Transit access also adds to the appeal. Brentwood's development overview highlights The Meridian area near the Brentwood Metrolink station, which includes office, retail, restaurant, bus loop, and park-and-ride access. That kind of transit-oriented location can attract renters who want flexibility in how they get around the region.
Who Rents in Brentwood
The renter profile gives you a clearer picture of who may be looking for housing here. According to Point2Homes' Brentwood rental profile, Brentwood has 1,468 renter-occupied housing units, a 36% renter share, and a 3.9% rental vacancy rate.
That vacancy rate points to a fairly tight market. It does not guarantee easy leasing for every property, but it does suggest there is real demand when a rental is priced and presented well.
The same report shows that the largest renter age groups are 25 to 34 years old at 35% and 35 to 44 years old at 27%. Most renter households are non-family households, and the average renter household size is 1.64.
That matters because it helps you match the property to the likely renter. In Brentwood, demand appears to lean toward younger and mid-career professionals, couples, and single occupants, with a smaller share of larger households.
What Property Types May Perform Best
Brentwood has a mix of housing options, which gives investors more than one path to consider. The city's new resident guide says the housing stock includes single-family homes, condominium developments, and apartments.
That mix matters because rental demand is not limited to one product type. Depending on your budget and goals, you may be looking at a condo, a single-family home, or a small multifamily property.
Based on the renter data, smaller units appear to be the clearest fit. Point2Homes reports 927 two-bedroom rentals, 387 one-bedroom rentals, and 107 three-bedroom rentals in Brentwood.
Pricing data points in the same direction. The same source says 60.14% of apartments are priced in the $1,500 to $2,000 range, and the average apartment rent was $1,711 as of October 2025, up 9.8% year over year.
In practical terms, the most promising opportunities may include:
- Updated one-bedroom or two-bedroom condos
- Well-located apartments
- Small multifamily properties with efficient unit layouts
- Renovated single-family homes in strong commuter locations
Three-bedroom homes can still work, but the renter mix suggests smaller households are the core audience in Brentwood.
Older Homes and Newer Infill
Age of housing can shape both your budget and your renovation plan. Point2Homes shows that renter-occupied units were most commonly built in the 1950s, with another meaningful cluster built between 2000 and 2009.
That tells you Brentwood can support both renovated older properties and newer infill product. If you are buying an older asset, condition and updates will likely play a major role in rent potential and tenant appeal.
Is Brentwood a Good Cash Flow Market?
The honest answer is: it depends on your strategy. Brentwood looks more attractive for investors who want stable demand, a strong location, and a quality tenant pool than for investors chasing the lowest entry price or the highest possible cash-on-cash return.
Public numbers show why careful underwriting matters. Census QuickFacts reports a median owner-occupied home value of $299,700, median gross rent of $1,439, median monthly owner cost with a mortgage of $1,719, and median property taxes paid on mortgaged homes of $3,573 in 2023.
When home values, taxes, insurance, financing costs, and upkeep are all part of the picture, your margin can get tight if you overpay or overestimate rent. Brentwood can make sense, but it usually works best when you buy well and manage the details carefully.
Key Numbers to Underwrite
Before you buy a rental in Brentwood, review the full picture, not just the list price and estimated rent. At a minimum, you should model:
- Market rent by bedroom count
- Expected vacancy
- Turnover costs
- Property taxes
- Insurance
- HOA dues, if any
- Maintenance reserves
- Capital improvement reserves
- Property management fees, if applicable
- Financing terms
This is especially important in a compact, established market where small differences in block, condition, updates, parking, and access can affect rent performance.
What Makes a Smart Brentwood Rental Buy
A smart rental buy in Brentwood usually checks a few boxes. It is in a convenient location, aligned with the likely renter pool, and updated enough to compete without requiring a major immediate capital outlay.
In many cases, that means a property with one or two bedrooms, functional layout, solid parking, and clean, modern finishes. For single-family homes, easy access to major roads and nearby commercial areas can also help support tenant interest.
You should also pay attention to turnover risk. Point2Homes reports the median year renters occupied their unit is 2018, which suggests movement in and out of rentals is part of the market. That makes good pricing, strong marketing, and efficient tenant placement especially important.
How a Local Agent Can Help
In a market like Brentwood, local knowledge can make a real difference. Because the city is centrally located, mixed-use, and compact, pricing and positioning are not always obvious from broad county-level data alone.
An experienced local agent can help you compare likely rents, evaluate how a property fits the renter profile, and look more closely at costs that may affect your returns. If you are planning to lease the home after purchase, support with listing prep, marketing, showings, screening, lease execution, and handoff to management can also save time and reduce mistakes.

Final Takeaway
So, is Brentwood a smart place to buy a rental property? For many investors, yes, but for the right reasons. Brentwood appears to offer meaningful renter demand, a strong commuter-friendly location, relatively tight vacancy, and rent levels above the county median.
It may not be the best fit if your goal is ultra-low acquisition cost or outsized cash flow. But if you want a well-located St. Louis-area submarket with solid fundamentals and a renter base that values convenience and quality, Brentwood deserves a close look.
