Introduction: The STR Playbook Has Changed — Most Advice Hasn’t
If you spend even a few minutes online researching short-term rentals in Nashville, you’ll notice something immediately:
Most of the advice hasn’t evolved.
Investors are still being told to:
-
“Just buy in an STR-friendly area”
-
“Max out bedroom count at all costs”
-
“Furnish it nice and let Airbnb do the rest”
-
“Use average AirDNA numbers and you’ll be fine”
That advice may have worked years ago.
In 2026, it’s actively hurting investors.
Nashville’s STR market hasn’t disappeared — but it has matured. And in a mature market, average execution produces average (or below-average) results.
Why So Much STR Advice Is Now Wrong
The biggest issue with outdated STR advice isn’t that it’s malicious — it’s that it’s incomplete.
Most guidance still focuses on surface-level qualifiers instead of performance drivers.
The Old Focus:
-
Zoning eligibility
-
Raw bedroom count
-
Generic revenue projections
-
“Set it and forget it” management
The Reality in 2026:
Zoning is the entry ticket.
Performance is driven by execution.
“Zoning doesn’t make a property perform — it just allows it to exist as a short-term rental. What happens after that is where investors either win or quietly underperform.”— Jack Costigan
What Actually Drives STR Performance in Nashville Today
At The Costigan Group, we advise STR clients very differently than most agents or online forums because we’re looking at real operating data, not theoretical averages.
Here are the levers that actually matter in 2026.
1. Deal Selection (Not Just Deal Availability)
Many STR investors still start with what’s available, not what underwrites.
We start with:
-
Purchase price discipline
-
All-in cost basis
-
Downside protection if regulations or demand shift
“The biggest mistake we see is investors falling in love with a property before they understand the numbers. A good STR deal has to make sense before you ever talk about design or marketing.”— Jack Costigan
We stress-test deals using conservative assumptions — not best-case projections — so clients aren’t surprised after closing.
2. Layout & Sleep Strategy (Not Bedroom Count)
More bedrooms do not automatically mean more revenue.
What matters is:
-
Functional sleeping arrangements
-
Bathroom count relative to guest count
-
How the home actually lives for groups
We regularly see:
-
3-bed homes outperform 5-bed homes
-
Better reviews drive higher nightly rates
-
Guest experience beating raw capacity
Outdated advice pushes square footage and beds.
Modern STR strategy prioritizes comfort and usability.
3. Design & Furnishing as a Revenue Tool
Design is no longer cosmetic — it’s economic.
Generic furniture packages produce generic results.
We guide clients on:
-
Design themes that photograph well
-
Durable materials that survive high turnover
-
Intentional moments that drive bookings
“Design isn’t about being trendy — it’s about creating something guests remember and choose again. That’s where pricing power comes from.”
— Jack Costigan
This is one of the biggest differentiators between STRs that plateau and those that outperform year after year.
4. Marketing, Pricing, and Listing Strategy
Airbnb doesn’t reward “nice” listings.
It rewards engagement, conversion, and consistency.
We help clients:
-
Position listings for the right guest profile
-
Optimize titles, photos, and descriptions
-
Implement dynamic pricing strategies that reflect real demand
Most underperforming STRs aren’t “bad properties” — they’re badly positioned businesses.
5. Treating STRs Like Businesses — Not Side Projects
This is the biggest mindset shift we push with clients.
“The old days of passive STR investing are gone. The investors who win in 2026 are the ones treating these properties like real businesses.”
— Jack Costigan
That means:
-
Pro-forma underwriting
-
Intentional design decisions
-
Marketing execution
-
Ongoing performance reviews
This is why we tell investors upfront:
If you want truly passive, STRs may not be the right play.

Final Thoughts: The Market Has Moved On
Nashville’s STR market isn’t broken.
It’s just no longer forgiving.
Outdated advice creates false confidence — and false confidence is expensive.
The investors performing best in 2026 aren’t guessing.
They’re underwriting conservatively, executing intentionally, and treating STRs like businesses.
That’s the difference.
