Honest comparison

TrueCap vs AirDNA: STR revenue data vs full underwriting

Q: Is TrueCap an AirDNA alternative?

No — AirDNA is STR market + revenue data. TrueCap is the underwriting calculator. AirDNA feeds revenue inputs; TrueCap runs cap rate / DSCR / cash flow on top. STR investors use both.

Q: AirDNA vs Mashvisor — which one for STR data?

AirDNA is gold-standard for STR-specific data (ADR, occupancy, RevPAR). Mashvisor covers STR + LTR + broader market. STR-primary: AirDNA. LTR/STR toggle: Mashvisor.

Q: Does AirDNA do cap rate or DSCR calculations?

No — AirDNA gives projected STR revenue. Plug that into TrueCap, DealCheck, or your spreadsheet to compute cap rate, DSCR, cash flow.

Q: How accurate are AirDNA's revenue projections?

Industry standard but not perfect. Derived from real Airbnb + Vrbo data, but depends on comp match. Always run sensitivity (TrueCap Pro's grid stress-tests AirDNA's projection at -20% etc.).

Q: Can I use TrueCap free with AirDNA?

Yes. TrueCap free covers cap rate, CoC, DSCR, cash flow. Pull AirDNA's monthly revenue, override TrueCap's HUD rent field, run the analysis. Pro not required for the basic workflow.

AirDNA is the gold standard for short-term rental market data — Airbnb / Vrbo occupancy rates, ADR, RevPAR by market and individual property. TrueCap is the underwriting calculator that turns AirDNA's revenue projections into a full deal analysis (cap rate, DSCR, cash flow, projection). AirDNA feeds the inputs; TrueCap runs the math.

Common questions about TrueCap vs AirDNA

Quick answers to the questions investors comparison-shopping these tools actually ask.

Is TrueCap an AirDNA alternative?

No — they solve different problems. AirDNA is STR market + revenue data; TrueCap is the underwriting calculator. AirDNA feeds revenue inputs; TrueCap runs the cap rate / DSCR / cash flow math on top. STR investors typically use both.

AirDNA vs Mashvisor — which one for STR data?

AirDNA is more focused and considered the gold standard for STR-specific data (ADR, occupancy, RevPAR). Mashvisor covers STR too but also includes LTR data and broader market analysis. If STR is your primary strategy, AirDNA wins. If you toggle between LTR and STR, Mashvisor's broader scope wins.

Does AirDNA do cap rate or DSCR calculations?

No — AirDNA gives you projected STR revenue. You'd plug that revenue into a separate calculator (TrueCap, DealCheck, or your spreadsheet) to compute cap rate, DSCR, and cash flow.

How accurate are AirDNA's revenue projections?

They're the industry standard but not perfect. AirDNA's Rentalizer reports are derived from actual Airbnb + Vrbo data, so they're tighter than guesses but still depend on the property being a good comp match in the local market. Always run sensitivity (TrueCap Pro's sensitivity grid lets you stress-test) — what happens if AirDNA's projection is 20% high?

Can I use TrueCap free with AirDNA?

Yes — TrueCap's free tier covers the full underwriting math (cap rate, CoC, DSCR, cash flow). Pull AirDNA's monthly revenue projection, override TrueCap's HUD rent field with it, run the analysis. You don't need TrueCap Pro for the basic combined workflow.
