Quick decision matrix
- “You need address-level STR revenue projections.” AirDNA Rentalizer.
- “You have the revenue and need full underwriting.” TrueCap (free for basic, Pro for sensitivity).
- “You're scouting which city to invest in.” Mashvisor.
- “You've already closed and need to operate the STR.” Hostaway or Hostfully (PMS).
- “You want a single all-in-one tool.” No single tool covers the full workflow — pair a revenue-data tool with an underwriting tool, then add a PMS after closing.
FAQ
What's the best all-in-one STR investment tool?
There isn't one. STR investing requires three different jobs: revenue projection (AirDNA), underwriting (TrueCap or DealCheck), and post-purchase ops (Hostaway / Hostfully / Lodgify). Tools that claim to do all three either do one well and the others poorly, or are enterprise-priced. Plan on pairing a revenue-data tool with an underwriting tool before you buy, then adding a PMS after closing.
AirDNA vs Mashvisor for STR — which one?
AirDNA is more STR-specific: it publishes ADR, occupancy and RevPAR by market. Mashvisor covers both STR and LTR plus broader market analysis. If you only buy short-term rentals, AirDNA's narrower focus fits. If you compare LTR and STR on the same property, Mashvisor's broader scope fits.
Can TrueCap model short-term rental revenue?
Yes, in beta. TrueCap's Short-term Rental mode models revenue as nightly rate × occupancy; it does not fully model platform fees, turnover, lodging tax, seasonality or local STR eligibility. TrueCap doesn't pull AirDNA data automatically; you copy the numbers across.
What management rate should I use for STR underwriting?
Management fees vary by market and service level, so get written quotes from local long-term and full-service STR managers. If you self-manage, still budget for software, cleaning coordination and your own time. TrueCap's management field is editable.
Does TrueCap support the STR tax loophole?
No. TrueCap does not currently expose a tax-specific analysis module, determine STR eligibility, or model cost-segregation components and bonus depreciation. Use a qualified tax professional for material-participation, REPS, cost-segregation, and taxpayer-specific modeling.
