BNBCalc vs Rabbu 2026: Which One Do You Actually Need?

Rabbu will show you a free estimate. It will not show you the country the way Zillow and Realtor.com will, and it will not show you the house the way BNBCalc will.

Zillow and Realtor.com are wider. They are the listing sites: price, photos, beds, baths, lot, taxes, and days on market, nationwide. Rabbu is not as wide. Find the house on one of those two. Paste the Zillow link into our search. We run the analysis.

Our entry plan, the Calculator, is $16.66 a month billed annually. Markets, if you want the research layer too, is $33 a month billed annually. A BNBCalc market is a metro region, not a city. Each market contains thousands of cities. A long list of cities is not wider coverage than that.

The questions that matter

	BNBCalc	Rabbu
Where is the listing coverage wider?	You don't need Rabbu for it. Zillow and Realtor.com are wider, and you paste the Zillow link into our search	Not as wide as Zillow or Realtor.com
What is a "market"?	A metro region. Thousands of cities inside each one. 487 of those in the US	A city list. Cities are not metros
What does the estimate know about the house?	Zestimate, property facts, and an AI underwriter that uses details and amenities	A free figure. The comps stay hidden
Which rental sites?	Airbnb and Vrbo, 10 million properties	Not Zillow-wide, and not both major rental sites at our depth
Does it have an AI underwriter?	Yes. Unlimited reports. It uses the property details and amenities	No
How many comps does it return?	Up to 50. Graded, and you can throw one out	The comps stay hidden
If I add an amenity, do I see the revenue change for this bedroom count?	Yes	No
Can I track material-participation hours for the STR tax tests?	Yes. Included	No
What do I pay, billed annually?	$16.66 a month for the Calculator. $33 a month for Markets, with property-manager rankings and 3.5 years of history	Free, because the estimate leads to agents and lenders
Can I use it on my phone at the house?	Yes. It stays fast	Not as a full underwrite

Listings belong on Zillow and Realtor.com

Those two sites are the record of a house for sale. Rabbu's coverage is not as wide. Using Rabbu to hunt inventory means hunting inside a smaller map than the one the listing is already on.

Paste the Zillow link into BNBCalc. We pull the property, including the Zestimate and the property facts, and the AI underwriter builds revenue from the details and the amenities. That is the step Rabbu does not do.

Cities are not markets

If someone quotes thousands of cities, they are counting places inside a metro, not metros. One BNBCalc market holds thousands of cities. 487 US markets is the national set of metros, and the same product continues outside the US. Do not let a city counter sound like more coverage.

Price

$16.66 a month, billed annually, is the Calculator: the address, the comps, and the loan. $33 a month, billed annually, is Markets, and it includes that Calculator, property-manager rankings, and 3.5 years of history. Rabbu is free because you are the lead. Free is not the same as wide.

The phone

Finish it on the phone. BNBCalc stays fast at the property. A free estimate on a small screen is not the comps, the facts, and the loan.

Frequently asked questions

Is Rabbu enough if it is free?

No. It is not as wide as Zillow or Realtor.com for the listing, and it does not enrich the house or underwrite from the details and amenities. The Calculator is $16.66 a month billed annually.

Are 3,500 cities more coverage than 487 markets?

No. Our markets are metro regions. Thousands of cities sit inside one market. Counting cities inflates the map.

Can I paste a Zillow link?

Yes. Paste it into the BNBCalc search box. We analyze that house.

The bottom line

Look up the house where the listing actually is. Paste the Zillow link into BNBCalc. $16.66 a month billed annually for the underwrite, on a phone, with the property facts Rabbu never had.
