Rabbu vs Mashvisor: which short-term rental tool finds better deals?

Short answer

Rabbu is the better free sourcing tool: type an address, get a short-term-rental revenue estimate, and browse listings with existing rental history. Mashvisor is stronger for screening entire neighborhoods and comparing short-term against long-term returns before you have a property in mind.

Option A

Rabbu

Free property-level STR revenue estimates plus a marketplace of investor-ready listings.

Strengths

Address-level revenue and occupancy estimates at no cost
Marketplace listings often include documented STR performance history
Investor filters surface cash-on-cash and cap-rate candidates quickly
Fast enough to screen a dozen addresses in one sitting

Trade-offs

Neighborhood-level analytics are thin next to subscription platforms
Coverage is deepest in popular US investor markets, sparse elsewhere
Single-number estimates hide the comp spread that actually matters
No long-term rental comparison built in

Option B

Mashvisor

A subscription research platform with neighborhood analytics and side-by-side short-term versus long-term projections.

Strengths

Neighborhood-level heat maps make market screening fast
Compares short-term and long-term returns on the same property
Built-in cashflow modelling with financing assumptions
Broader coverage of secondary and tertiary markets

Trade-offs

Meaningful use requires a paid subscription
Neighborhood averages can be wildly wrong for a specific street
Data freshness varies by market and lags in thin ones
No marketplace — you still source deals elsewhere

Badge marks which option wins that row: A = Rabbu, B = Mashvisor.

Mashvisor is worth paying for before you know your market; Rabbu wins once you do.

The order of operations decides the tool. If you have not chosen a market, neighborhood analytics are the expensive part to reproduce yourself and a month of subscription is cheap. Once you have settled on two or three zip codes and are screening actual addresses, free property-level estimates plus your own comp research beat paying monthly for maps you have already read. The failure mode for both is the same: underwriting the headline number. Neither tool sees your cleaning contract, your HOA's rental cap, or the ordinance that passes next spring.

Worked example: Screening a $310,000 three-bedroom in a mid-size STR market

Rabbu estimate: $48,000 annual gross at 64% occupancy
Mashvisor neighborhood median: $205 ADR, 58% occupancy
Rebuilt gross: $205 × 365 × 0.58 = about $43,400
Operating costs at 45% of gross: about $19,500 — NOI about $23,900
Debt service on $248,000 at 2026 rates: roughly $19,000 per year
Cash flow about $4,900 on roughly $77,000 invested — about 6.4% cash-on-cash

The two tools differ by $4,600 of gross revenue, which is the entire margin of the deal. Underwrite the lower number and stress-test occupancy 15 points below it before making an offer.

The verdict

Choose Rabbu

Pick Rabbu when you already know your target market, want free address-level estimates, or want to buy a property that comes with rental history attached.

Choose Mashvisor

Pick Mashvisor when you are still choosing between markets, need neighborhood-level screening, or want short-term and long-term returns compared on the same property.

Or run both

Use Mashvisor for a month to pick the market, Rabbu to source addresses inside it, and your own cashflow model to decide.

Frequently asked questions

Are Rabbu's revenue estimates reliable?

They are modelled from comparable listings, not measured from your future bookings. Treat them as a screening filter that tells you which properties deserve a real underwrite, and rebuild the number from a comp set of similar bedroom count, amenities, and distance before making an offer.

Is Mashvisor worth the subscription?

For market selection, one or two months usually is — reproducing neighborhood-level ADR and occupancy data by hand takes far longer than the fee is worth. For ongoing use after you own the property, dynamic pricing tools generally deliver more value per dollar.

How do these compare to AirDNA?

AirDNA sits between them: deeper comp-set tooling than either, priced above both. A common workflow is Rabbu for free sourcing, AirDNA for the final underwrite of finalist properties, and Mashvisor when the question is which market rather than which house.

What do all three miss?

Local regulation, HOA restrictions, permit caps, and your real cost base. A market can look excellent on data and be uninvestable because the city capped new permits last year. Always check the ordinance before the spreadsheet.

Methodology

Feature comparisons reflect each platform's published 2026 offerings; pricing and free-tier limits change often, so verify before subscribing. The worked example uses illustrative mid-market figures and 2026-typical financing costs — pull live comps for any real decision.
