Short-Term Rental Investing: What the Numbers Actually Look Like

A 2-bedroom Airbnb in a mid-tier vacation market charges $150 per night and runs at 70% occupancy. The math looks like this: 365 nights × 70% occupancy × $150 ADR = $38,325 in gross annual revenue. The comparable long-term rental in the same area? $1,500 per month, or $18,000 per year. That's a $20,000 spread, and it's why short-term rental investing has attracted so much capital over the past decade.

What the headline numbers don't tell you is that the operating cost structure of an STR is fundamentally different from a long-term rental — and the gap between gross revenue and net income is much wider than most new investors expect.

The Revenue Math

STR income depends on three variables you need to estimate conservatively:

Gross Revenue = Occupancy Rate × Average Daily Rate (ADR) × 365

Occupancy and ADR are inversely related — raise your nightly rate and occupancy usually falls. Finding the right pricing to maximize revenue per available night (RevPAR) is the core operational challenge of STR management.

• ADR benchmarks: Highly seasonal markets (beach towns, ski resorts) can push $200–$400+ in peak season but may fall to $80–$100 in the off-season. Mid-tier leisure markets run $100–$175. Urban markets with business travel demand tend to be less seasonal.
• Occupancy benchmarks: 65–75% occupancy is a realistic target for an established listing with good reviews in a solid market. New listings often run 50–60% in their first year as they build review history. Anything above 80% sustained may indicate underpricing.
• Seasonal variance: If you're in a seasonal market, model it month by month. A beach property at 90% in July and 30% in January has a very different revenue profile than a flat 60% year-round, even if the annual average looks the same.

STR Operating Costs That Kill Margins

The operating cost structure for an STR is fundamentally different from a long-term rental. Some costs are higher. Some are entirely new. All of them need to be modeled accurately before you decide whether the premium revenue is worth it.

Cleaning Fees

Every turnover requires a professional clean. In most markets, professional STR cleaning runs $80–$150 per turnover for a 2-bedroom unit. At 70% occupancy on a 2-bedroom with an average stay of 3 nights, you're looking at roughly 85 turnovers per year. At $100 per clean, that's $8,500 annually in cleaning costs alone. You can pass some of this to guests as a cleaning fee, but in competitive markets, high cleaning fees hurt your conversion rate and ranking.

Platform Fees

Airbnb charges hosts approximately 3% of the booking subtotal. VRBO charges a 5% service fee plus payment processing. If you're running dual-listed on both platforms plus a direct booking site, plan for blended platform costs of 3–5% of gross revenue. On $38,325, that's $1,150–$1,916 per year — not devastating, but it adds up.

Supplies and Consumables

Toiletries, paper products, coffee, cleaning supplies, linens that need replacing — budget $50–$100 per month for a 2-bedroom as a starting point. High-turnover properties run higher. This is an expense category that's easy to underestimate and hard to eliminate.

Furnishing Cost

A long-term rental is typically rented unfurnished. An STR needs full furniture, kitchen equipment, bedding, towels, decor, and smart home devices (smart locks, noise monitors, cameras). A modest but functional 2-bedroom STR setup runs $5,000–$10,000. A well-designed property that competes for premium rates may need $15,000–$20,000 in furnishings. This is upfront capital that doesn't earn a return — it just enables the business.

Higher Insurance and Utilities

STR insurance is a specialized product. Standard landlord insurance typically excludes STR activity. Dedicated STR coverage (or a commercial policy) costs $2,000–$4,000+ per year compared to $900–$1,500 for a standard landlord policy. You're also paying utilities — guests don't pay their own electricity and water, unlike long-term tenants. Budget $150–$300/month in utilities depending on climate and usage.

Management Fees

If you hire a professional STR manager, expect to pay 20–35% of gross revenue. On $38,325 gross, that's $7,665–$13,414 per year. Compare this to long-term rental management at 8–10% of rents, which on $18,000 annual rent would be $1,440–$1,800. The management premium for STRs is real and significant.

Regulatory Risk Is Real and Growing

The single largest risk in STR investing isn't occupancy or ADR — it's regulation. Cities across the country have restricted or outright banned whole-unit short-term rentals:

• New York City effectively banned most STRs with Local Law 18, which requires hosts to be present during guest stays and limits bookings to two guests.
• San Francisco caps STR activity at 90 nights per year for non-owner-occupied units.
• Many smaller cities have implemented permit systems, annual caps, or zoning restrictions that limit where STRs can operate.
• HOAs in condo buildings frequently prohibit short-term rentals in their CC&Rs — and they can enforce it after you close.

Before you invest, research current regulations, pending legislation, and HOA rules thoroughly. Stress-test your underwriting at long-term rental income levels. If the deal doesn't work as an LTR, the regulatory risk becomes an existential threat to your investment.

How to Research STR Demand

The right tools for market research before an STR purchase are AirDNA and Rabbu. Both aggregate real booking data to give you:

• Average daily rates by market, neighborhood, and property type
• Occupancy rate trends by month
• Revenue estimates for specific addresses
• Number of active listings and supply growth trends

Use these tools critically. The revenue estimates shown often reflect top-performing listings, not typical ones. A new listing without reviews won't match the numbers of an established listing with 500 five-star reviews. Pull the median performer, not the top, as your baseline projection.

Also look at supply growth. A market where STR listings are growing 20% per year may see occupancy rates compress over time as more inventory chases the same demand.

STR Arbitrage: Lower Capital, Higher Risk

STR arbitrage is the practice of signing a long-term lease on a property and then subletting it on Airbnb or VRBO at higher nightly rates. You capture the spread between what you pay in rent and what guests pay you.

It requires significantly less capital than ownership — instead of a down payment, you need first month, last month, security deposit, and furnishings. But the risk profile is different: your landlord can evict you at any time, most leases explicitly prohibit subletting, and you're building no equity while bearing all the operating costs of an STR business.

Arbitrage can work at scale with explicit landlord agreements in writing. Without that, it's one eviction notice away from collapse.

When Long-Term Rental Still Wins

The STR premium is real but not universal. LTR often wins when:

• The property is in a market with weak STR demand and low ADRs
• Local regulations cap STR activity significantly
• You don't want to manage (or pay to manage) an active hospitality business
• The LTR cap rate already meets your target return without the operational complexity
• The property type or location doesn't attract STR guests (urban apartments far from tourist areas, for example)

A solid long-term rental producing reliable cash flow and equity growth often outperforms a marginal STR when you account for the full cost of operations, management intensity, and regulatory exposure.
