How to Analyze a Short-Term Rental Deal in Under 10 Minutes

You do not need an afternoon and three spreadsheets to vet a deal. Here is the 10-minute framework top investors use.

Most people overcomplicate deal analysis because they're working with incomplete data — jumping between AirDNA, Zillow, a calculator, and a gut feeling. When your inputs are right, the analysis itself is fast. This framework assumes you have the right inputs. If you're not sure where those come from, AirDNA vs. Real Comps: Why STR Revenue Estimates Are Often Wrong is worth reading first.

‍

1. Pull the revenue range

Start with the full range, conservative to top performer, not a single estimate. Anchor your underwriting to the realistic (75th percentile) number.

A single average number — whether it comes from AirDNA, a listing agent, or a back-of-napkin calculation — is not a safe foundation for an offer. You need the spread. What does a median operator earn? What does the 75th percentile earn? What does a top performer in the same comp set earn? Those three numbers tell you the floor, your realistic target, and your upside — and they determine whether this deal is worth your next 9 minutes.

This is also where knowing your market deeply pays off. Investors who have done the work to find profitable markets fast already have a baseline sense of what a realistic 75th percentile number looks like for a given bedroom count in a given area — which means they can spot a weak projection almost immediately.

2. Check the comps and amenities

Look at the real operating comps nearby and note what the top earners have that this property does not: a hot tub, a game room, a standout design feature. Those gaps are your upside, or your required capex.

This step is where most investors either skip past the detail or get lost in it. The goal is simple: identify the 2–3 amenity gaps between this property and the top performers in its comp set. If the top earners all have a hot tub and this property doesn't, that's either a capex line item or a reason to underwrite closer to the 50th percentile. If the property already has everything the top performers have, your upside case gets stronger.

3. Estimate expenses, then cash-on-cash

Subtract management, cleaning, platform fees, utilities, taxes, and insurance. A strong STR cash-on-cash return typically lands between 8% and 12%.

The expense side is where deals that looked good on revenue fall apart. Management fees alone can run 20–30% depending on whether you're self-managing or using a PM. Add platform fees, cleaning, restocking, utilities, insurance, property taxes, and any HOA costs, and you can easily be looking at 45–55% of gross revenue going out before debt service.

If you're still figuring out what a realistic all-in budget looks like for your first or next property — including reserves, furnishing, and setup costs — The Real Cost of STR Investing: How Much You Need to Get Started lays it out clearly.

4. Read the deal score

A single score that blends revenue, comps, and returns tells you fast whether a property is worth a deeper look, so you can kill the 9 bad deals and focus on the 1 good one.

The deal score is the output of steps 1 through 3 compressed into a single signal. It doesn't replace your judgment — it focuses it. A low score means one of your three inputs is weak: the revenue range is narrow, the comps don't support the asking price, or the returns don't clear your threshold. A high score means all three are aligned and the deal deserves your full attention.

This is also the point where having a clearly defined buy box pays off. If you already know your minimum cash-on-cash, your target bedroom count, and your preferred markets, reading the deal score takes seconds rather than minutes. Why Defining Your Buy Box Helps You Scale STR Investing Faster walks through how to build that criteria so every deal score is evaluated against a consistent standard.
