Mashvisor 2026 Review: Is the Rental Data Still Accurate?

Mashvisor's rental data is a score on top of US comps you cannot audit. It is strongest as a way to glance at Airbnb versus a lease. It is a weak way to decide what a specific short-term rental will earn, and you pay for a year before you find that out.

BNBCalc wins this comparison. The data is more accurate. It is the best value. It is the only one of these platforms you can actually use on a phone. And it is the best data for the price.

Accuracy

Mashvisor's opportunity score sorts a list. It does not show you whether the comps underneath are a fair match or a handful of outliers. In rural markets that handful is the whole sample. BNBCalc grades every comp and flags the bias.

Why this matters: the number you buy the house on has to survive a look at the comps.

Winner: BNBCalc

Price

The Calculator is $16.66 a month billed annually. Markets is $33 a month billed annually and includes the Calculator, with a 7-day trial. Mashvisor starts at $39.99 a month if you pay the year up front. There is no trial and no refund, so you pay before you can check the comps. Markets is $33 a month billed annually, you can try it for 7 days, and the underwrite is included.

Why this matters: a market read you still have to finish in a spreadsheet is not a bargain.

Winner: BNBCalc

Mobile

BNBCalc is the only one of these platforms that is actually usable on a phone, in the experience and in the speed. You can rank a market, open the comps, and finish the underwrite there. Mashvisor is a research console. BNBCalc is the one that stays fast on a phone, comps and loan included.

Why this matters: the decision usually happens at the property.

Winner: BNBCalc

The underwrite

Mashvisor is built to compare an Airbnb projection with a long-term lease. It does not carry a short-term rental through a full expense stack and a mortgage you can edit line by line. BNBCalc does, and it covers markets Mashvisor's US listings never reach.

Give BNBCalc the purchase price, down payment, loan, and rate. You get the monthly payment, cash-on-cash, cap rate, and month-by-month cash flow. The same address can run as a short-term rental, an arbitrage, a long-term lease, or a cohost.

Why this matters: revenue is the easy half. The loan is where the deal works or fails.

Winner: BNBCalc
