Why Social Media Lies to You About Short-Term Rentals
The โ30 Unitโ Fantasy vs. Reality
Scroll Instagram for five minutes and youโll see it.
Some guy in front of a pool in Scottsdale.
Another one standing on a Nashville rooftop.
โJust buy your first Airbnb. Then do it again. Then again. Scale to 30.โ
It sounds clean. Simple. Mechanical.
But hereโs the part nobody wants to say:
โFor most people, owning one STR today is hard. Owning two is harder. Owning thirty is nearly impossible without real infrastructure.โ โ Jack Costigan
Social media has turned short-term rental investing into a highlight reel. The philosophy of asset ownership gets discussed endlessly โ mindset, freedom, passive income.
What rarely gets discussed is how this actually works in practice.
And thatโs where most people get burned.
The Capital Lie: โJust Use a DSCR Loanโ
Letโs start with financing.
Most short-term rentals today are financed using DSCR loans. That sounds simple online. What influencers donโt explain is what that really means.
โข 20โ25% down
โข Six months of reserves (sometimes more)
โข Strong liquidity
โข Clean credit
โข Proven rental performance
This isnโt FHA with 3.5% down.
Itโs real money.
On a $1,000,000 STR in Nashville, youโre talking:
โข $250,000 down
โข $40,000โ$80,000 in furnishings
โข $20,000โ$50,000 in reserves
โข Closing costs
Thatโs $350,000+ cash before your first guest checks in.
And thatโs for one property.
โWhen someone online says โjust buy another STR,โ what theyโre skipping over is the fact that you need hundreds of thousands of dollars in cash to keep doing this.โ โ Jack Costigan
This is the first place most scaling dreams die.
Underwriting Is Harder Now โ Not Easier
The โbuy, refinance, repeatโ strategy worked differently in 2020โ2021.
Prices were lower.
Rates were lower.
Occupancy was booming.
Nightly rates were surging.
Today?
Rates are higher.
Purchase prices are higher.
AirDNA projections are flatter.
Competition is heavier.
Margin for error is thin.
A deal that misses by 10% can completely wipe out your return.
Thatโs why serious underwriting matters more now than ever.
At The Costigan Group, we spend hours inside spreadsheets before we ever show a property. Every client gets conservative underwriting, stress-tested scenarios, and real-world projections based on seasonality, not fantasy.

Scaling bad underwriting just scales risk.
STR Income Is Not Smooth
Another lie social media tells:
โSTR cash flow is consistent.โ
Itโs not.
STR income is volatile.
โข Summer spikes
โข Shoulder seasons dip
โข Event-driven surges
โข Unexpected maintenance
โข Regulatory shifts
โข Algorithm changes
You donโt get a fixed rent check on the first of the month.
You get bookings โ if your listing is performing.
โShort-term rental income isnโt smooth month to month. Anyone telling you otherwise hasnโt owned one long enough.โ โ Jack Costigan
And when you stack multiple properties, volatility compounds.
One bad review.
One cleaner mistake.
One maintenance delay.
Occupancy drops.
Revenue dips.
Mortgage stays the same.
This is business income โ not passive income.
One STR Is a Business. Five Is a Job.
Hereโs the operational reality nobody glamorizes.
One STR:
Youโre running a business.
Five STRs:
You now have a second job.
Ten STRs:
You need systems, staff, or you break.
Guest communication.
Dynamic pricing.
Cleaners.
Laundry.
Restocking.
Maintenance coordination.
Review management.
Vendor oversight.
Insurance.
Accounting.
That doesnโt scale casually.
โFive STRs isnโt passive. Itโs a job. Ten STRs requires a real operation.โ โ Jack Costigan
Most influencers donโt show you the backend:
โข Virtual assistants
โข Revenue managers
โข Dedicated cleaning teams
โข Full-time maintenance staff
โข CRM systems
โข Bookkeeping support
Theyโre not doing this at night after their W-2.
The Quality Decline Problem
Hereโs what actually kills large portfolios.
Quality erosion.
As you scale:
โข Youโre farther from the asset.
โข You rely on more vendors.
โข Small issues slip.
โข Reviews soften.
โข Ranking drops.
โข Occupancy follows.
When quality drops, revenue follows.
Itโs math.
And reviews are unforgiving.
A 4.9 โ 4.7 drop materially impacts bookings.
Thatโs the part social media never shows.
They show acquisition.
They donโt show reputation management.
The Truth About the โ30 Unitโ Operators
Most large-scale STR owners fall into one of three categories:
They bought years ago at radically different pricing.
They use outside capital or partnerships.
They operate full infrastructure teams.
They are not:
โข Buying with 5% down.
โข Running everything themselves.
โข Scaling casually.
โThe people flexing thirty units arenโt doing this on nights and weekends with a spreadsheet.โ โ Jack Costigan
They are running companies.
Which is fine โ if thatโs your goal.
But most people donโt want to build a hospitality company.
They want financial leverage.
Those are two very different things.
Why 1โ3 Great STRs Beat 30 Average Ones
Hereโs the strategic shift.
For most high-income professionals, athletes, physicians, and business owners we work with, the optimal strategy is:
โข Own one to three exceptional assets.
โข Buy right.
โข Finance correctly.
โข Protect reviews.
โข Protect occupancy.
โข Protect margins.
That approach wins.
When you own a few strong performers:
โข You maintain control.
โข You protect quality.
โข You protect reputation.
โข You protect underwriting assumptions.
โFor most people, one to three STRs done correctly beats chasing thirty on paper every time.โ โ Jack Costigan
Scaling prematurely introduces fragility.
And fragile portfolios break first when markets tighten.
The Infrastructure Conversation
If you do want to scale beyond three properties, hereโs what that actually requires:
โข Dedicated revenue management
โข Cleaner redundancy
โข Maintenance reserves
โข Vendor accountability
โข Bookkeeping systems
โข Tax planning strategy
โข Capital planning
You are no longer an investor.
Youโre an operator.
And that requires intentional build-out.
At The Costigan Group, we advise clients on both models โ boutique portfolio vs. operational scale โ but the strategy has to match capital, bandwidth, and goals.
Anything else is gambling.
The Real Takeaway
The social media version of STR investing is simple.
The real version is nuanced.
Itโs capital-intensive.
Itโs management-heavy.
Itโs volatile.
Itโs reputation-driven.
Itโs underwriting-sensitive.
And it rewards discipline โ not hype.
If your goal is sustainable wealth, not Instagram optics, then the smarter play is patience and precision.
Get one right.
Then maybe a second.
Then maybe a third.
Only scale when systems support it.
โScale without infrastructure doesnโt create freedom. It creates stress.โ โ Jack Costigan
Build a Portfolio, Not a Fantasy
The short-term rental space is still powerful.
Nashville remains one of the strongest long-term hospitality markets in the country. Demand is real. Tourism is real. Event traffic is real.
But success in this space today requires:
โข Serious underwriting
โข Real capital
โข Operational discipline
โข Review protection
โข Conservative projections
The era of sloppy deals working automatically is over.
Thatโs not bad news.
It just means strategy matters more.
If youโre serious about entering the STR space in Nashville โ or scaling intelligently โ the conversation shouldnโt start with โHow do I get to 30 units?โ
It should start with:
โHow do I get the first one right?โ
Because when you protect the first one, everything else becomes optional.
When you chase thirty without structure, everything becomes fragile.
Choose structure.
Choose discipline.
Choose long-term math over short-term ego.
Thatโs how real portfolios get built.
FAQ Section
Is short-term rental investing still profitable in 2026?
Yes โ but only when properly underwritten. Higher rates and pricing require conservative projections and disciplined acquisitions.
How much cash do I need to buy an STR in Nashville?
Most DSCR-financed STR purchases require 20โ25% down plus furnishings and reserves. For a $1M property, that can exceed $300K total cash needed.
Can I scale STRs quickly?
Scaling is possible but requires infrastructure. Without systems, quality drops โ and revenue follows.
Is owning multiple STRs passive?
One STR is manageable. Five becomes a job. Ten requires a team.
