Why Investors Consider Saint Charles

Saint Charles attracts investor interest thanks to its above-average revenue-to-price ratio and occupancy stability, offering a compelling entry point in the greater St. Louis metro area.

Expert Market Assessment

"Saint Charles earns an "Attractive Opportunity" designation, driven primarily by its above-average revenue-to-price ratio and occupancy stability. Seasonality is a clear factor — revenue swings from a low of $1,404 in January to a peak of $3,902 in July, meaning investors should plan for roughly a 2.8x spread between the softest and strongest months. The supply/demand balance is the one area that warrants caution, as rapid listing growth (105% year-over-year) could compress margins if demand doesn't keep pace. Still, the market's fundamentals are sound for investors who price strategically and target higher-earning property sizes."

Key Airbnb Metrics & Trends in Saint Charles

Average revenue by month in Saint Charles

Revenue in Saint Charles follows a pronounced seasonal curve, peaking at $3,902 in July and bottoming out at $1,404 in January — a nearly 2.8x spread. The May-through-October stretch consistently delivers above-average monthly revenue, making summer and early fall the primary earning window for investors.

Active Airbnb listings by property size in Saint Charles

Two-bedroom units dominate the supply with 42 active listings, followed closely by 1-bedrooms (32) and 3-bedrooms (31). Larger configurations are notably underrepresented — just 20 four-bedroom and 7 five-bedroom listings — which could signal a supply gap for investors targeting higher-revenue property sizes.

Average daily rate (ADR) by property size in Saint Charles

ADR climbs steadily from $146 for 1-bedroom listings to $243 for 5-bedroom properties, though the rate premium flattens between 4-bedroom ($239) and 5-bedroom units. The sharpest jump occurs moving from 2-bedrooms ($164) to 3-bedrooms ($232), suggesting that stepping up to a 3-bedroom offers the most meaningful pricing uplift relative to the next size down.

Average RevPAN by property size in Saint Charles

Revenue per available night scales strongly with size, from $40 for 1-bedrooms to $98 for 5-bedroom properties. Four- and 5-bedroom listings deliver nearly identical RevPAN ($97 vs. $98), reflecting their similar occupancy rates and nightly rates — making 4-bedrooms potentially the more capital-efficient choice.

Average occupancy rates by property size in Saint Charles

Four- and 5-bedroom listings lead occupancy at 41%, well ahead of 1-bedrooms (28%), 2-bedrooms (31%), and 3-bedrooms (29%). This gap means larger properties not only command higher nightly rates but also fill more consistently, offering stronger cash-flow predictability for investors.

Average monthly revenue by property size in Saint Charles

Monthly revenue ranges from $1,572 for 1-bedroom listings to $4,284 for 5-bedroom properties, with each step up in bedrooms delivering meaningful incremental income. The jump from 3-bedrooms ($3,129) to 4-bedrooms ($4,092) is particularly notable, adding nearly $1,000 per month for investors willing to operate larger homes.

Average annual revenue by property size in Saint Charles

Five-bedroom properties top annual revenue at $51,411, closely followed by 4-bedrooms at $49,104 — both significantly outpacing 1-bedroom listings at $18,868. Given the limited supply of 4- and 5-bedroom units in the market, these configurations present the strongest revenue potential for investors targeting top-line performance in Saint Charles.

Most common amenities for Airbnb listings in Saint Charles

Parking (99%), kitchen (98%), and self check-in (94%) are near-universal among Saint Charles listings, establishing them as baseline guest expectations rather than differentiators. Amenities like hot tubs (8%) and pet-friendliness (40%) remain less common and may offer competitive advantages for hosts looking to stand out and command premium rates.

Understanding Saint Charles's ROI Score: 64/100

Rabbu's ROI Score is a proprietary metric that evaluates short-term rental investment potential based on multiple factors.

How the ROI Score is Calculated

What This Means for Investors

Saint Charles's ROI score of 64 out of 100 places it in the "Attractive Opportunity" band, anchored by above-average marks in both revenue-to-price ratio and occupancy stability — the two most heavily weighted factors. Market growth trend is average and supply/demand balance rates below average, reflecting the rapid 105% year-over-year increase in active listings that could introduce competitive pressure. Pairing these metrics with thorough local regulatory research will give investors a well-rounded view of whether this market fits their portfolio goals.

Short-Term Rental Regulations in Saint Charles

Understanding local STR regulations is essential before investing in Saint Charles. Here's the current regulatory landscape:

Permit Requirements

Short-term rental operators in Saint Charles, Missouri may be required to obtain a permit or business license before listing their property. Investors should verify current registration and permit requirements directly with the City of Saint Charles and relevant Missouri state agencies before purchasing.

Key Restrictions

Common restrictions that may apply to STR properties in markets like Saint Charles include occupancy limits, minimum stay requirements, noise ordinances, off-street parking mandates, and potential HOA covenants. Some municipalities also impose caps on the number of active permits, so it's important to research whether any such limitations are in effect locally.

Tax Obligations

Short-term rental hosts in Missouri are generally subject to state and local sales taxes, as well as any applicable transient occupancy or tourism taxes. Platforms like Airbnb often collect and remit certain taxes on behalf of hosts, but operators should confirm their full obligation with the Missouri Department of Revenue and local tax authorities.

Regulations subject to change. Always verify with local authorities before purchasing. A Rabbu partner agent specializing in Saint Charles can provide current regulatory guidance.

Future Outlook & Long-Term Forecast

"Over the next 12–18 months, demand in Saint Charles is expected to remain stable, with occupancy rates likely holding in the 30–34% range given the market's above-average occupancy stability. Seasonal revenue patterns suggest summer months will continue to drive the bulk of annual income, with July potentially generating $3,800–$4,000 per listing. ADR growth may track modestly at 1–3% as the market matures, though the below-average supply/demand balance indicates new listings could put some competitive pressure on pricing. Investors who target 4- or 5-bedroom properties may be best positioned to capture premium nightly rates and stronger occupancy through the year."
