Airbnb Due Diligence Checklist: What to Research Before Buying

The allure of Airbnb and short-term rental (STR) investments is undeniable for today's savvy investors. While top-performing STRs can yield 2-3x the revenue of a traditional rental, a poorly vetted property can quickly drain finances, capital, and time. The difference between a lucrative investment and a costly mistake often comes down to one factor: thorough Airbnb due diligence.

For high-income professionals and experienced investors seeking to diversify their portfolios with passive income streams, understanding STR investments is essential. This checklist covers everything you need to research before making an offer on a short-term rental property.

At STR Search, we've guided investors through over $90 million in successful real estate transactions using a data-first approach. This checklist covers the diligence pillars we analyze to ensure every investment has the highest potential for success.

Understanding Short-Term Rental Regulations

Before analyzing a property's potential returns or amenities, confirm you can legally operate a short-term rental. This regulatory verification is the first and crucial step in your Airbnb due diligence process. Even a property with exceptional profit potential is worthless as an STR investment if regulations prohibit such use.

Short-term rental regulations are hyper-local and constantly evolving. Cities that once welcomed STRs may implement restrictions overnight, while others might gradually loosen their stance. This landscape requires meticulous research and continual monitoring.

Municipal and County Ordinances

Local governments control the most critical aspects of STR regulation. Before proceeding with any property, investigate the following regulatory elements:

• Is non-owner-occupied (investment) STR activity permitted? Some jurisdictions only allow "home-sharing" where the owner lives on-site.
• Are there zoning restrictions limiting STRs to specific commercial or tourist zones?
• Are there caps on STR permits in the city/county? Is there a waitlist, and if so, how long?
• What are the licensing/permit requirements, fees, and renewal processes?
• What operational rules exist for occupancy limits, noise restrictions, and parking requirements?
• What are the local lodging/transient occupancy tax rates and collection methods?

Manually tracking these rules for every market is a monumental task. That’s why the first filter in the STR Search analytics platform is a comprehensive regulatory check, immediately flagging properties in non-viable locations.

State-Level Legislation

Municipalities often lead regulation efforts, but state laws can preempt local rules or add requirements. Some states have passed legislation addressing short-term rentals, while others regulate them under existing hospitality or landlord-tenant laws.

Research state-specific taxes, safety requirements (like mandatory fire extinguishers, carbon monoxide detectors, or inspection certifications), and pending legislation that could impact the STR market in your target area.

Homeowners Association (HOA) and Condo Association (COA) Rules

Many investors overlook this critical area. HOA and COA restrictions supersede city ordinances regarding property use. Even if your target city permits STRs, your Homeowners Association's Covenants, Conditions, and Restrictions (CC&Rs) can prohibit them.

When considering a property governed by an HOA or COA, obtain and review the association's governing documents. Pay particular attention to:

• Minimum lease term requirements (e.g., "no rentals under 30 days")
• Prohibitions against "transient occupancy" or "hotel-like use"
• Guest registration requirements
• Restrictions on advertising the property for short-term use
• Special assessments or fees for rental properties

These restrictions can change through HOA voting, making them less stable than municipal regulations.

Finding Your High-Performing Location

Once you've confirmed a location is regulation-friendly, the next step is a comprehensive STR market analysis. This isn't about intuition or assuming popular tourist destinations guarantee success. It's about using data to validate demand patterns and revenue potential.

At STR Search, our proprietary analytics shine, and we'll show you the core metrics for conducting your own data-driven market analysis.

KPIs to Analyze

• Average Daily Rate (ADR): This is the average rental revenue per paid occupied day. Reviewing comparable properties can provide a baseline, but ADR varies by property size, amenities, location, and season. Beware of relying on city-wide averages, which can be misleading if they include everything from studio apartments to luxury mansions.
• Occupancy Rate: This represents the percentage of booked available nights. A healthy rate is crucial for profitability, and the target varies by market. Seasonal destinations might see 80%+ occupancy during peak months but drop in off-seasons. Analyze at least 12 months of historical data to understand annual patterns.
• Revenue Per Available Room (RevPAR): This metric (ADR × Occupancy Rate) provides a more complete picture than either metric alone. A property with a high ADR but low occupancy generates less total revenue than one with moderate ADR and consistent bookings. Compare RevPAR across seasons to understand a property's year-round performance.
• Seasonality and Demand Drivers: Identify what drives tourism to the area. Is it beaches, ski resorts, national parks, convention centers, or major employers? Understanding these drivers helps predict future performance. Markets with multiple drivers (e.g., summer and winter attractions) offer more stability than one-season destinations.

Competitive Landscape (The 'Comp Set')

Analyzing direct competitors: properties of similar size, quality, and guest capacity: provides insights into your potential property's performance. Study your competitors' listings carefully:

• What amenities do guests mention in reviews?
• What criticisms appear in their negative reviews? These represent opportunities for differentiation.
• How do they structure their pricing across seasons, weekends, and special events?
• What is their booking lead time (how far in advance do they fill up)?

Copying competitors isn't a winning strategy, but understanding the competitive landscape helps identify opportunities and pitfalls.

While public tools like AirDNA or PriceLabs offer a surface-level view, STR Search's platform analyzes real-time data from millions of listings to create a hyper-accurate 'comp set,' projecting revenue with a higher degree of confidence.

Your Short-Term Rental Property Checklist

With the market validated, it's time to evaluate the physical asset. A successful STR property must be optimized for the guest experience, not a typical long-term rental or primary residence. This short-term rental property checklist will guide your evaluation.

Layout, Functionality, and 'Instagrammability'

• Bed & Bath Count: Does the property's configuration match the highest-demand properties in your market analysis? Some markets prefer specific bed counts (e.g., 3BR/2BA may be the sweet spot in family-oriented destinations).
• Functional Layout: Is there a logical space flow? Open-concept living/kitchen areas typically perform better as STRs since they facilitate group socializing. Are there sufficient private spaces for guests to retreat to?
• ‘Wow' Factor: Does the property have unique features that stand out in listing photos? Great views, distinctive architecture, a hot tub, or a well-designed game room can increase bookings. In the STR world, the "scroll-stopping" first photo is crucial for booking conversion.
• Outdoor Space: Private outdoor areas like decks, patios, or yards attract STR guests. They feature prominently in reviews and justify premium pricing.
• Condition & Deferred Maintenance: Document any immediate repairs or updates needed (roof, HVAC, plumbing, electrical). Factor these costs into your initial investment budget and leverage them for negotiation.

Essential and Desirable Amenities

Must-Haves:

• High-speed Wi-Fi (with documented speed tests)
• Smart TV with streaming capabilities
• Reliable heating and air conditioning
• Fully stocked kitchen with quality appliances
• Keyless entry system
• Comfortable, high-quality beds and linens

Revenue-Boosters:

• Hot tub (increases ADR by 15-25%)
• Swimming pool (climate appropriate)
• Fire pit or outdoor fireplace
• Game room features (pool table, arcade games, etc.)
• Dedicated workspace for remote workers
• Pet-friendly accommodations can expand your market.

Our team analyzes a property's current state and identifies high-ROI improvements. We model for clients before they make an offer how adding a hot tub can increase ADR by 15-25%.

The Ultimate Vacation Rental ROI Test

This is where everything comes together. A thorough STR investment analysis moves beyond gross revenue to focus on net operating income (NOI) and cash-on-cash return. This final analysis represents your ultimate go/no-go decision point for the investment.

Projecting Gross Rental Income

Creating an accurate revenue projection requires synthesizing market data on ADR, occupancy rates, and seasonality. Avoid simplistic calculations like "ADR × 365 days," which can overstate potential income.

Build a month-by-month projection accounting for seasonal fluctuations, local events, and a reasonable vacancy buffer. Even in hot markets, perfect occupancy is unrealistic due to maintenance, booking gaps, and seasonal downturns.

Accounting for EVERY Expense (The Most Common Mistake)

New STR investors often miscalculate. The expense list for short-term rentals is significantly longer than for traditional rentals:

• Mortgage (PITI): Principal, Interest, Taxes, Insurance.
• Utilities: Unlike long-term rentals, STR owners cover all utilities: electric, water, gas, internet, cable/streaming services, and trash removal. These costs can be substantial, especially in properties with pools, hot tubs, or in extreme climates.
• Property Management Fees: If you're not self-managing, expect to pay 20-30% of gross revenue to a professional manager. This includes guest communication, booking management, and coordination of cleaning and maintenance.
• Channel/Booking Fees: Airbnb and VRBO charge 3-5% of booking revenue.
• Supplies & Consumables: Toilet paper, paper towels, coffee, soap, shampoo, laundry detergent, and other guest supplies add up quickly.
• Cleaning Fees: You need to manage this cash flow, as it is often passed to guests. You may need to cover cleaning costs between closely spaced bookings.
• Maintenance & Repairs Fund: Budget 5-10% of gross revenue for ongoing maintenance. STRs experience more wear and tear than traditional rentals.
• CapEx Fund: Set aside funds for long-term capital expenditures like roof replacement, HVAC systems, and major appliances.
• Furnishings & Setup Costs: Initial furnishing is a significant upfront expense (often $15,000-$50,000+ depending on property size and quality). You need a replacement budget for ongoing refresh.
• Licenses, Permits, and Taxes: Annual permit fees, lodging taxes (if not collected by the booking platform), and potentially higher property taxes if your area assesses STRs at commercial rates.

Calculating Your Potential Return

Once you've projected both revenue and expenses, calculate these key metrics:

• Net Operating Income (NOI): Gross Income - Operating Expenses (excluding mortgage)
• Cash-on-Cash Return (CoC): This shows the percentage return on your actual cash outlay (down payment, closing costs, furnishings, and renovations).

For high W-2 earners, the analysis doesn't stop here. Significant tax advantages can boost your real returns. We help clients understand how to offset taxes through STR investments.
