The 75-55 rule is an informal benchmark used by Airbnb investors to evaluate a property’s profit potential before making a purchase. It suggests that a short-term rental should achieve at least 75% occupancy at a rate no less than 55% of the market average nightly rate to be considered viable. If a property can’t meet both thresholds, it may struggle to cover costs and generate meaningful returns.

Short-term rental investing has its own language, and the 75-55 rule is one of the more useful phrases in that vocabulary. It won’t appear in any official Airbnb documentation, but experienced STR investors and lenders use it as a quick-screen tool, a way to pressure-test a property’s numbers before you’re too far down the road.
If you’re thinking about buying an Airbnb property, refinancing an existing one, or using a hard money loan or equity to fund a short-term rental acquisition, understanding this rule can save you from a costly miscalculation.
What the 75-55 rule actually means
The 75-55 formula:
Total Viability = (Market ADR x 0.55) x (365 x 0.75).
- The 75% occupancy threshold means your property should be booked roughly three out of every four nights across a rolling period (typically measured monthly or annually). At this level, most properties in moderate-cost markets generate enough gross income to cover mortgage payments, platform fees, insurance, and basic operating costs.
- The 55% rate threshold means you should be able to command at least 55% of the market’s average daily rate (ADR) for comparable listings in your area. This floor accounts for slow seasons, competitive pressure, and the inevitable gaps between bookings.
Together, these two benchmarks give you a minimum viability floor. A property that hits both numbers isn’t guaranteed to be a home run, but one that can’t hit either is almost certainly a problem.
Why investors and lenders pay attention to it
When you’re evaluating an Airbnb property, it’s easy to get pulled toward best-case projections. Listing platforms and market data tools often surface peak-season numbers that look impressive on paper but don’t reflect what you’ll actually collect across a full year.
The 75-55 rule forces a more conservative question
Can this property perform adequately even when things aren’t perfect?
Lenders who specialize in short-term rental financing ask a version of this question, too.
If you’re applying for a DSCR loan or a hard money loan through a lender like Park Place Finance, underwriters will look at projected or actual rental income against your debt obligations.
A property that pencils out only at 90% occupancy and peak ADR is a much riskier collateral position than one that works at 75% occupancy and a discounted rate.
Key factors lenders typically evaluate include:
- Documented rental income history (if the property is already operating)
- Market occupancy data from tools like AirDNA or Mashvisor
- Comparable listings and their average daily rates
- Seasonal demand patterns in the target market
- Local STR regulations and licensing requirements
How to apply the rule before you buy
Before making an offer on a potential Airbnb property, run it through this simple framework:
| Step | What to do |
| 1. Find the market ADR | Use AirDNA, Mashvisor, or Airbnb’s own search to identify the average nightly rate for comparable listings nearby |
| 2. Calculate your rate floor | Multiply the market ADR by 0.55 — this is the minimum nightly rate you should be able to sustain |
| 3. Model at 75% occupancy | Multiply your rate floor by the number of nights in a year (365), then by 0.75 |
| 4. Run your expenses | Stack that gross income figure against your mortgage, taxes, insurance, platform fees (typically 3%), and management costs |
| 5. Check your margin | If you’re profitable in this conservative scenario, the property is worth a closer look |
If the numbers only work at higher occupancy or higher rates, you’re underwriting on optimism rather than investment discipline.
Where the 75-55 rule has limits
The 75-55 rule is a starting filter, not a complete analysis. Urban cores, top-tier vacation destinations, and properties with unique amenities are examples of markets where average occupancy routinely runs above 80% and premium pricing is the norm. In those cases, the rule may be unnecessarily conservative.
Conversely, in oversaturated markets or areas with tightening STR regulations, even 75% occupancy at 55% ADR may not be sufficient to sustain positive cash flow after accounting for all costs.
Use the rule to screen, then go deeper with full pro forma modeling before committing capital.
Financing your Airbnb property with the right loan structure
Once you’ve identified a property that clears the 75-55 threshold, the next step is structuring your financing intelligently. Hard money loans and DSCR loans are both commonly used for short-term rental acquisitions, and each has a role depending on your timeline and exit strategy.
Park Place Finance specializes in fast, flexible financing for real estate investors, including short-term rental properties.
Whether you’re looking to acquire, renovate, or refinance an Airbnb property, having a lender who understands STR income is a meaningful advantage.
Your next move starts with the right numbers
The 75-55 rule gives you a disciplined starting point — a way to cut through inflated projections and ask whether a property can genuinely carry itself. If it passes that screen, the next question is how to fund it efficiently.

A: No. It’s an informal benchmark used by experienced short-term rental investors and lenders to evaluate a property’s minimum viability before purchase.
A: AirDNA, Mashvisor, and Rabbu are the most widely used platforms for short-term rental market data, including occupancy rates and average daily rates by location.
A: It depends on the loan type. DSCR loans evaluate the property’s income potential rather than your personal income, making them well-suited for STR investors. Park Place Finance can walk you through your options.
A: No. High-demand markets may consistently exceed the thresholds, while oversaturated or heavily regulated markets may require stricter standards to achieve meaningful cash flow.
A: Meeting only one threshold is a warning sign. The rule works because both components interact — high occupancy at a deeply discounted rate or a strong nightly rate with poor occupancy can result in insufficient gross income to cover costs.
