The Short-Term Rental Due Diligence Checklist: What to Verify Before You Buy

Most STR deals that go sideways after closing failed in due diligence, not in market analysis. The seller’s P&L looked strong. The inspection passed. But the revenue was inflated by owner-blocked dates and cherry-picked peak months, the expenses were understated by 30%, and the property tax bill doubled after closing because nobody accounted for the assessment cap reset.

I have watched this pattern play out repeatedly across the Orlando corridor. As a realtor who also owns and operates vacation rentals through my management company FunStay Florida, I have seen the gap between what sellers present and what the actual numbers look like from the operator side. This checklist is the same framework I walk my investor clients through before they close on any short-term rental property.

Why STR Due Diligence Is Different

When you buy a traditional rental property, due diligence is mostly about the physical structure: roof condition, plumbing, electrical, foundation. When you buy a short-term rental, you are also acquiring a hospitality business. The property’s income is driven by listing performance, guest reviews, seasonal demand, and operating efficiency, none of which show up in a standard home inspection or appraisal.

A standard real estate transaction evaluates the property. STR due diligence evaluates the property and the business that runs on top of it. That means verifying revenue against independent data sources, auditing the full expense stack (not just what the seller discloses), and inspecting for commercial-grade wear patterns that residential inspectors are not trained to flag.

This checklist covers the financial and physical verification side of STR due diligence. For licensing requirements, county registration, zoning verification, and compliance basics, see our companion vacation rental due diligence checklist on FunStay Florida.

Revenue Verification: How to Audit the Seller’s Numbers

Revenue verification is the single most important step in STR due diligence, and the one most buyers skip. Airbnb revenue verification requires more than glancing at a seller’s summary. Sellers will almost always present the most favorable version of their income numbers. Your job is to verify independently and understand exactly what those numbers represent.

What to Request (OTA Payouts, Not Just a P&L)

A seller-prepared P&L is a starting point, not proof. Request these documents directly:

• OTA payout statements (24+ months): Download the full transaction history from Airbnb and Vrbo. These show every booking, cancellation, alteration, fee deduction, and net payout. This is the most reliable revenue source outside of tax returns.
• Schedule E tax returns (2-3 years): The income they reported to the IRS. If the seller’s P&L shows $85K but Schedule E shows $62K, you have a discrepancy that needs explaining.
• Property management statements: If a PM company is involved, request monthly owner statements showing gross bookings, management fees (typically 20-35% for full-service STR management), maintenance charges, and net owner distributions.
• Direct booking records: Any revenue from Stripe, Square, PayPal, or a direct booking site. This income often goes unreported in casual P&L summaries.

Revenue verification works differently for new builds versus resales. For a deeper look at that distinction, see our new construction vs. resale comparison.

Red Flags That Inflate Revenue

Operator Insight

Run the property address through AirDNA and Rabbu independently. If the seller claims $80K annual revenue but both tools estimate $55-60K for comparable properties in the same community, that gap tells you the seller’s numbers may include one-time spikes, personal use manipulation, or simple overstatement.

Expense Verification: The Costs Sellers Leave Out

The expense side is where most STR deals fall apart quietly, and it is where the real hidden costs of a short-term rental surface. Sellers present operating costs of 25-35% of gross revenue. In practice, the real number for a fully managed vacation rental is 45-65%. That gap can turn what looks like a $20K annual cash flow into a break-even or negative return.

The Full Expense Stack

If the seller tells you the property costs $2,000/month to operate, run your own numbers. On a 4-5 bedroom vacation home in the Orlando corridor, the realistic range is $4,500-$8,000+ per month when you account for everything. The communities I work in, like ChampionsGate, have three layers of recurring fees (HOA, CDD, and county taxes) that stack up quickly.

CapEx Reserves for Florida STR

Set aside 8-10% of gross rental revenue for capital expenditure reserves. Florida’s climate is hard on properties: AC units last 10-15 years (budget for 7-10 in practice, at $5,000-$12,000 per unit), pool resurfacing runs $5,000-$15,000 every 7-12 years, exterior paint needs refreshing every 5-7 years, and carpet in bedrooms lasts 3-5 years under guest traffic. These are not hypothetical costs. They are predictable line items that sellers rarely include in their expense presentations.

The STR Inspection Addendum

A standard home inspection covers the major systems: roof, electrical, plumbing, HVAC, structure. For a vacation rental, you need a vacation rental inspection checklist that adds an STR-specific layer addressing items residential inspectors are not looking for.

Indoor cameras: Airbnb banned all indoor cameras as of April 30, 2024. If the property has indoor cameras, they must be removed before listing. Outdoor cameras must be disclosed in the listing. Florida is an all-party consent state for audio recording.

Title, Taxes, and Insurance

Title Red Flags Specific to Vacation Rentals

STR properties carry lien risks that do not apply to typical residential purchases. Beyond the standard title search, look for these:

• HOA assessment liens (Fla. Stat. 720.3085): HOAs have “super lien” status in Florida. Unpaid regular and special assessments, late fees, interest, and attorney fees all attach to the property and survive a sale.
• Code enforcement liens (Fla. Stat. 162.09): If the property was operating as an STR without proper licensing or had maintenance violations, daily fines of $100-$500 may have accrued. These liens can be substantial and are sometimes discovered only during the title search.
• CDD assessments (Fla. Stat. Ch. 190): Non-optional annual assessments of $1,500-$4,000+ that appear on the property tax bill. CDD bonds run 20-30 years. These are not a deal killer, but they are a recurring cost that many out-of-state buyers overlook.
• Mechanic’s liens (Fla. Stat. 713.08): Contractors can file liens for unpaid renovation or repair work within 90 days of completing the job.

Obtain an estoppel letter from the HOA before closing. Under Florida Statute 720.30851, HOAs have 10 business days to respond and can charge up to $250. This letter confirms all amounts owed and will surface any hidden assessments.

The Property Tax Surprise (Save Our Homes)

This is the most commonly overlooked cost by out-of-state STR investors in Florida.

Florida’s assessment cap system (Save Our Homes for homesteaded properties at 3%, and Amendment 1 for non-homesteaded properties at 10%) limits how much assessed value can increase each year. But both caps reset to full market value when the property sells. If a property has been held for years with capped increases, the new buyer’s tax bill can be dramatically higher than the seller’s.

Example: A property with a current assessed value of $250,000 (held down by years of capped increases) sells for $500,000. The new assessed value resets to approximately $500,000. On a property in Osceola County with a millage rate around 17-20 mills, that means taxes jump from roughly $4,500/year to $8,500-$10,000/year, plus CDD assessments. The seller’s current tax bill tells you nothing about what you will pay.

STR investment properties do not qualify for the $50,000 homestead exemption. Always calculate your projected property taxes based on the purchase price, not the seller’s current bill.

For insurance, you need an STR-specific commercial policy (not a standard HO-3). Standard homeowners policies contain a business activity exclusion that can void coverage entirely if the insurer discovers undisclosed STR activity. Budget $3,000-$6,000/year for a policy with $1M per occurrence liability coverage. Osceola County requires proof of $1M liability for STR licensing.

Contract Contingencies for STR Purchases

The standard FAR/BAR contract covers financing, appraisal, inspection, and title contingencies. For an STR purchase, you need to add provisions that protect your ability to operate the property as a rental business after closing.

1. Revenue verification contingency: Seller provides verifiable income documentation (OTA payout statements, tax returns, Schedule E). Language: “Contingent upon verifying the property generated at least $[X] in gross rental revenue over the trailing 12 months.”
2. STR licensing/zoning contingency: Buyer’s obligation is contingent on confirming the property is zoned for STR use and all required permits can be obtained. STR licenses in Florida are non-transferable; the new owner must apply separately.
3. Insurance contingency: Contingent on obtaining STR-specific insurance at commercially reasonable rates with minimum $1M liability. Given Florida’s volatile insurance market, this protects you from discovering post-contract that coverage costs make the deal unworkable.
4. Booking transfer agreement: Airbnb and Vrbo do not automatically transfer existing bookings to a new owner. The contract should specify: who owns the future bookings, how guests will be notified, how deposits are handled, and whether the listing photos and reviews transfer.
5. Furnishing inventory: Request a complete inventory of all furnishings, appliances, electronics, and amenities included in the sale. This is typically handled as a separate bill of sale since appraisers exclude personal property. Furnishings for a 4-5 bedroom vacation home can represent $15,000-$50,000 in value.

Frequently Asked Questions

How do you verify Airbnb revenue before buying?

Follow these five steps:

1. Request the seller’s OTA payout statements (the full transaction history export, not a summary) for at least 24 consecutive months.
2. Cross-reference the booking calendar against an AirDNA historical availability report. Look for owner-blocked dates that reduce true occupancy.
3. Check for owner-block inflation, where the seller blocks peak-season dates for personal use, making their “available night” occupancy rate look higher than the actual earning potential.
4. Compare the seller’s claimed revenue against AirDNA and Rabbu estimates for comparable properties in the same community. A gap of more than 15-20% is a red flag.
5. Request Schedule E tax returns for 2-3 years. The income reported to the IRS is the most reliable verification point.

What should I look for when buying a vacation rental?

Beyond the standard home inspection, focus on these eight items that are specific to short-term rental properties: (1) verified revenue from OTA payout statements and tax returns, (2) a complete expense stack including management fees, cleaning costs, HOA, CDD, and utilities, (3) pool barrier compliance and guest safety features, (4) roof age and insurability, (5) property tax recalculation based on purchase price (not the seller’s current bill), (6) STR-specific insurance availability, (7) HOA rules confirming short-term rentals are allowed, and (8) a booking transfer agreement for any future reservations.

Do I need special insurance for a short-term rental in Florida?

Yes. A standard homeowners policy (HO-3) contains a business activity exclusion that can void your entire coverage if the insurer discovers you are renting the property to guests. You need an STR-specific commercial policy that covers guest injuries, property damage from guest use, and liability claims. Budget $3,000-$6,000 per year for a policy with $1M per occurrence liability coverage. Osceola County requires proof of at least $1M in liability as part of the STR licensing application. Before closing, confirm that a policy is available at commercially reasonable rates, because Florida’s insurance market has been volatile and some carriers have exited the state entirely.

Do property taxes go up when you buy a vacation rental in Florida?

Almost always, yes. Florida’s assessment cap system limits annual increases in assessed value (10% for non-homesteaded investment properties under Amendment 1), but that cap resets to full market value when the property transfers to a new owner. If the seller held the property for several years, their assessed value may be significantly below current market value. When you buy, the assessment resets to approximately your purchase price, and taxes are recalculated at that new assessed value. On a $500,000 property in Osceola County, annual property taxes typically run $8,500-$10,000 plus CDD assessments of $1,500-$4,000. Investment properties also do not qualify for the $50,000 homestead exemption. Always calculate your projected taxes based on the purchase price.
