Quick take
STR Numbers can replace Rabbu only for simple deal math. It helps you model cash flow, ROI, cap rate, and break-even occupancy, but it does not replace Rabbu's market data, property search, or investor marketplace.
Use STR Numbers for
- Testing a single address or deal with assumptions you control
- Seeing how financing, expenses, fees, and occupancy affect returns
- Running a fast free check before digging into market research
- Comparing a few scenarios without opening a full research platform
Use Rabbu for
- Exploring STR-ready homes and Airbnb investment properties
- Reviewing market data, revenue estimates, and location-level signals
- Connecting property search with agents, lenders, or investor resources
- Using a short-term rental investment marketplace
Run the numbers first
Run the core underwriting math once you have a property and assumptions to test.
STR Numbers vs Rabbu
This is not about crowning a winner. Pick the tool based on the question you are trying to answer.
Primary job
Run the numbers on one property.
Find, analyze, and research Airbnb investment opportunities.
Best first question
Does this property still work with conservative assumptions?
Which markets or properties look promising enough to research?
Inputs
User-entered purchase, financing, revenue, and expense assumptions.
Market data, property criteria, location inputs, and platform data.
Outputs
Cash flow, ROI, cap rate, break-even occupancy, and report download.
Revenue estimates, market data, property search results, and investor resources.
Cost posture
Free calculator for first-pass deal math.
Use Rabbu's current product pages for available tools and terms.
Main limitation
Does not provide a property marketplace or proprietary market data.
Still needs conservative expense, financing, and ownership assumptions.
How I would use them
Use STR Numbers when you already have a deal
If you are looking at a specific house, condo, or cabin, run the numbers first. You will see quickly whether the deal needs better revenue, cheaper debt, or a lower purchase price.
Use Rabbu when you are still hunting for markets or properties
If the question is where to buy or which STR-ready property to research next, market data or property search can be more useful than a blank calculator.
Use both before you buy
A practical order: find a promising property, check the revenue assumption, then enter conservative numbers into STR Numbers before making an offer.
