Quick take
STR Numbers can replace Mashvisor only for simple Airbnb and STR investment math. It helps you model one deal, but it does not replace Mashvisor's real estate analytics, property data, or market research.
Use STR Numbers for
- Running quick cash-flow math for a property you are already considering
- Testing financing, expenses, occupancy, and nightly rate assumptions
- Explaining the deal to a partner or lender without a long platform setup
- Comparing a few scenarios before paying for deeper research
Use Mashvisor for
- Finding and comparing investment properties across markets
- Using real estate data, projections, and estimates in one platform
- Researching rental strategies before narrowing to a specific deal
- Building a larger property research process
Run the numbers first
Run free Airbnb and STR investment math with your own assumptions.
STR Numbers vs Mashvisor
This is not about crowning a winner. Pick the tool based on the question you are trying to answer.
Primary job
Calculate whether a specific Airbnb or STR deal works.
Research markets and properties with real estate analytics.
Best first question
What happens if my assumptions change?
Which property or market should I analyze next?
Inputs
Manual deal assumptions for purchase, financing, revenue, and expenses.
Platform data, property search criteria, projections, and investment goals.
Outputs
Cash flow, ROI, cap rate, break-even occupancy, and report download.
Property analysis, rental projections, market data, and investment research.
Cost posture
Free calculator for early deal analysis.
Use Mashvisor's current pricing and product pages before deciding.
Main limitation
Does not provide property search or real estate analytics.
Still needs conservative property-level underwriting before a purchase decision.
How I would use them
Use STR Numbers for a quick underwriting pass
If you already have the address, asking price, and a rough revenue assumption, the calculator gives you a fast read on cash flow and break-even occupancy.
Use Mashvisor when you are still in research mode
If you are comparing markets, rental strategies, or many potential properties, a real estate analytics platform may be the better first stop.
Use both when the property looks promising
Use research tools to narrow the field. Then use STR Numbers to sanity-check the final deal with conservative debt, expense, and revenue assumptions.
