Why Investors Consider Caldwell

Caldwell appeals to investors seeking lower entry costs compared to Boise proper, though the market's compressed revenue-to-price ratio demands careful deal sourcing.

Expert Market Assessment

"Caldwell presents a competitive opportunity that rewards selective deal sourcing rather than broad-market buying. The ROI score of 50 out of 100 reflects below-average revenue-to-price ratios and a supply-demand balance that's tightening as listings surge. Seasonality is pronounced: July peaks near $2,620 per month while January bottoms out around $1,102, creating a revenue spread of nearly 2.4×. Investors targeting larger properties — particularly 4-bedroom homes — stand to capture meaningfully higher returns, but should budget conservatively for the quieter winter months."

Key Airbnb Metrics & Trends in Caldwell

Average revenue by month in Caldwell

Caldwell shows clear summer-dominated seasonality, with July ($2,620) and June ($2,500) delivering more than double the revenue of January ($1,102) and February ($1,120). Investors should plan cash reserves to bridge the November-through-February slow season, when monthly revenue stays in the $1,100–$1,550 range.

Active Airbnb listings by property size in Caldwell

One-bedroom listings lead the supply count at 30, followed closely by 3-bedroom properties at 25, while 2-bedroom (12) and 4-bedroom (13) units are less common. The relative scarcity of 4-bedroom homes — combined with their superior revenue metrics — may signal a supply gap worth targeting.

Average daily rate (ADR) by property size in Caldwell

ADR climbs steadily from $80 for 1-bedroom units to $221 for 4-bedroom properties, with the jump from 3-bedroom ($150) to 4-bedroom representing a 47% premium. This suggests that larger properties command disproportionate nightly rates, making the cost-to-ADR trade-off most compelling at the 4-bedroom tier.

Average RevPAN by property size in Caldwell

Revenue per available night nearly quadruples from $26 for 1-bedroom listings to $96 for 4-bedroom properties, reflecting both higher rates and better occupancy at the larger end. The gap between 3-bedroom ($50) and 4-bedroom RevPAN is especially dramatic, indicating that the extra bedroom adds outsized earning power.

Average occupancy rates by property size in Caldwell

Occupancy rates are relatively flat across 1- through 3-bedroom listings at 33–34%, but 4-bedroom properties break away at 44%. This 10-point advantage for larger homes translates directly into more consistent cash flow and fewer vacant nights throughout the year.

Average monthly revenue by property size in Caldwell

Monthly revenue ranges from $906 for 1-bedroom units to $2,923 for 4-bedroom properties, with 3-bedroom homes earning $2,095 — a solid middle ground. The nearly $1,000-per-month gap between 3- and 4-bedroom listings underscores the premium that larger properties capture in this market.

Average annual revenue by property size in Caldwell

Four-bedroom properties lead with $35,083 in average annual revenue, roughly 40% more than 3-bedroom listings at $25,141 and more than triple the $10,877 earned by 1-bedroom units. For investors evaluating return potential, the 4-bedroom configuration offers the strongest top-line revenue, though acquisition costs for larger homes should be factored in.

Most common amenities for Airbnb listings in Caldwell

Parking (98%) and a kitchen (92%) are near-universal in Caldwell's listings, reflecting the practical expectations of guests in a suburban Idaho market. Self check-in (79%), laundry facilities (72–74%), and backyard space (63%) are strong differentiators, while premium amenities like hot tubs (8%) and pools (2%) remain rare — presenting possible opportunities to stand out from the competition.

Understanding Caldwell's ROI Score: 50/100

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

Caldwell's ROI score of 50 out of 100 places it in the "Competitive Opportunity" band, meaning the market has genuine demand but requires disciplined deal selection. The below-average revenue-to-price ratio — driven by average home values near $582K against annual revenues around $21,477 — is the primary headwind, while occupancy stability and market growth trend land in the average range. Investors should pair this data with thorough local regulatory research and target higher-performing property types (especially 4-bedroom homes) to improve their odds of a viable return.

Short-Term Rental Regulations in Caldwell

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

Permit Requirements

Caldwell, Idaho may require short-term rental operators to obtain a business license or STR-specific permit before listing a property. Investors should verify current requirements directly with the City of Caldwell and Canyon County, as local regulations can evolve quickly in fast-growing Idaho markets.

Key Restrictions

Common STR restrictions in Idaho communities include occupancy limits tied to bedroom count, noise and nuisance ordinances, parking requirements for guests, and potential HOA covenants that may prohibit or limit short-term rentals. Some jurisdictions also impose minimum-stay requirements or cap the number of permits issued in a given area, so due diligence on the specific property and neighborhood is essential.

Tax Obligations

Short-term rental operators in Idaho are generally subject to state sales tax as well as local lodging or occupancy taxes. Platforms like Airbnb often collect and remit a portion of these taxes automatically, but hosts should confirm their full obligations with the Idaho State Tax Commission and Canyon County to ensure compliance.

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

Future Outlook & Long-Term Forecast

"Over the next 12–18 months, Caldwell's short-term rental landscape will likely be shaped by the rapid influx of new listings. With supply growing at 138% year-over-year, occupancy — currently at 35% versus a 41% state average — could face additional downward pressure unless demand keeps pace. Seasonal patterns suggest that summer months (June–August) will continue to anchor earnings, with monthly revenues in the $2,400–$2,600 range, while winter months may dip to around $1,100–$1,200. Investors should anticipate modest ADR growth of roughly 1–3% and plan conservatively for occupancy in the 32–38% range market-wide."
