What is the main difference between STRInvest and AirDNA?

AirDNA is a market research platform: it analyzes historical Airbnb and Vrbo performance data across markets and neighborhoods, showing occupancy rates, average daily rates, and revenue trends for STR properties in general. STRInvest is a deal analysis tool: it analyzes a specific property listing on Zillow or Redfin, calculating that property's projected STR revenue, cap rate, cash-on-cash return, and investment metrics given its price, location, and bedroom count. AirDNA answers 'What is the STR market like in Nashville?' STRInvest answers 'Is this specific Nashville 3-bedroom on Zillow a good investment at $485,000?'

Is AirDNA worth the cost for STR investors?

AirDNA's paid tiers start at $12–24/month for basic market data and scale to $90+/month for comprehensive analytics. For active STR investors analyzing multiple markets, AirDNA provides valuable market-level context that helps calibrate property-level projections. For investors focused on 1–2 specific markets, the value-to-cost ratio is less compelling — much of the data AirDNA surfaces is also available through free sources like Airbnb's host resources and the competitive listing data visible directly in Airbnb search results.

Can I use STRInvest without AirDNA?

Yes. STRInvest is a standalone Chrome extension that works directly on Zillow and Redfin listings without requiring an AirDNA subscription. STRInvest's revenue projections use its own comparable property data and market benchmarks for the property's location and bedroom count. AirDNA is a separate platform; STRInvest and AirDNA can be used together (AirDNA for market research, STRInvest for deal analysis) or independently.

What workflow do serious STR investors use for deal analysis?

The most effective workflow: (1) Use AirDNA or free market research to identify target markets — look for occupancy 60%+, strong ADR trends, and permissive regulations; (2) Set up Zillow saved searches for your target markets; (3) As new listings appear, run STRInvest to get the property-level deal analysis in 60 seconds; (4) Short-list properties with favorable STRInvest metrics; (5) Deep-dive on short-listed properties: view comparable Airbnb listings in the neighborhood, check regulatory status, schedule a showing; (6) Run a full financial model before making an offer. STRInvest compresses step 3 from 30+ minutes of manual research to under 60 seconds.

If I can only afford one STR analysis tool, which should I use?

For investors actively evaluating specific properties on Zillow or Redfin: STRInvest is the higher-value tool at the deal-evaluation stage. The property-level metrics (will this specific house at this price generate positive cash flow?) directly inform purchase decisions. AirDNA's market-level data is valuable context but doesn't answer the deal-specific question. For investors still in the market-selection phase (choosing which city or neighborhood to target): AirDNA's market analytics are more directly useful. Many investors use STRInvest for deal screening and AirDNA for market selection — both serve distinct functions in the research process.

STRInvest vs. AirDNA: Which STR Analysis Tool Is Right for You

What AirDNA does

AirDNA is a dedicated STR market analytics platform that aggregates data from Airbnb and Vrbo listings globally. Its core product is market-level data: average daily rate (ADR), occupancy rate, revenue per available room (RevPAR), and seasonal demand trends for a given market or zip code.

AirDNA is built for market research — understanding how a city, neighborhood, or zip code performs as an STR market. It's the tool you use when you're deciding which market to invest in. Its data is comprehensive, its visualizations are strong, and its market-level reports are the industry standard for STR operators and investors doing macro-level market selection.

AirDNA's pricing starts at around $40/month for basic market reports and climbs significantly for property-level data, API access, and multi-market subscriptions.

What STRInvest does

STRInvest is a Chrome extension that runs directly on Zillow, Redfin, and Realtor.com listing pages. It's built for a different moment in the investment process: when you're looking at a specific property and need to know whether this deal works.

When you open a listing with STRInvest installed, it surfaces projected Airbnb revenue (based on comparable active listings), calculates cap rate and cash-on-cash return using the listing price and your financing assumptions, checks local STR regulation status, and flags HOA restrictions — all without leaving the listing page.

STRInvest is free for 3 analyses per month, with unlimited analyses at $49/month.

The core difference: market research vs. deal analysis

The tools answer different questions:

AirDNA answers: "Is Nashville a good STR market? How does Scottsdale perform in Q1 vs. Q3? What's the average occupancy rate in this zip code?"
STRInvest answers: "Does this specific 3BR house at 123 Main St pencil as an STR? What's the cap rate? Are STRs even legal here?"

These are sequential questions in the investment process, not competing ones. You use market-level data to narrow your target markets, then deal-level analysis to evaluate specific properties.

Where they overlap

Both tools surface comparable Airbnb listings and revenue estimates. For a specific property, you might get slightly different revenue projections from each — AirDNA uses its own proprietary dataset while STRInvest uses active Airbnb listing data for the comp set. Neither is "right"; they're different samples of the same market.

If you're using both, treat them as a sanity check on each other: if STRInvest shows $4,200/month projected revenue and AirDNA's comps for the same zip code show $3,800/month average, you have a reasonable confidence range of $3,800–$4,200/month to underwrite against.

The workflow most serious STR investors use

Market selection (AirDNA)

Use AirDNA to identify which markets have strong STR fundamentals — high occupancy, rising ADR, manageable regulation risk. Narrow to 2–3 target markets.

Deal screening (STRInvest)

Browse listings on Zillow or Redfin in your target markets with STRInvest active. Quickly filter out deals that don't meet your return thresholds or are in regulated areas. This step takes seconds per listing.

Deep dive (both + your own model)

For deals that pass initial screening, pull AirDNA's comp data for the specific zip code, cross-reference with STRInvest's projections, and build your own underwriting model with conservative, base, and optimistic scenarios.

If you can only use one

It depends on where you are in your investment journey:

Just starting out / evaluating your first market: AirDNA gives you the market-level foundation you need before looking at specific deals. The investment is worth it if you're serious about market selection.
Already have a target market, evaluating deals: STRInvest is the more immediate tool. It meets you where you already spend your time — browsing listings — and adds the analysis layer without extra workflow.
Active investor screening at volume: Use both. The workflow above pays for itself with one deal avoided or one better deal found.

Bottom line: AirDNA is a market research tool. STRInvest is a deal analysis tool. They're complements, not substitutes — and STRInvest's free tier makes it a zero-cost add to any investor's toolkit.
