1. What is RV Park Due Diligence?

RV Park Due Diligence is the systematic investigative process conducted by a buyer after placing a campground or RV resort under contract. During this period—typically lasting 30 to 60 days—the buyer verifies the seller's financial representations, inspects critical subterranean utility infrastructure (water, septic/sewer, electrical grids), validates zoning and municipal permits, evaluates environmental liabilities, and assesses operational contracts before committing non-refundable earnest money.

Unlike traditional commercial real estate (such as multi-family apartments or triple-net retail), RV parks are hybrid operating businesses combined with active hospitality real estate. A minor flaw in a private septic absorption field or a transformer capacity deficit can cost hundreds of thousands of dollars to remediate. Thorough due diligence protects capital, uncovers hidden expenses, and prevents catastrophic post-closing operational failures.

2. The 4 Due Diligence Phases & Timeline

A disciplined due diligence period is executed in four sequential phases to minimize upfront inspection expenses until foundational items pass review.

3. Financial Audit & Revenue Verification

Never rely solely on seller-provided Profit & Loss (P&L) statements or marketing flyers. Always cross-reference three independent sources of historical financial records:

1. The Three-Way Reconciliation

To verify authentic top-line revenue, reconcile:

1. Federal Tax Returns (Form 1040 Schedule C, Form 1065, or Form 1120S) for the trailing 3 full calendar years.
2. Merchant Processing & Bank Statements: Verify that total monthly deposits match declared gross receipts.
3. Property Management System (PMS) Reports: Export historical reservation reports from Campspot, RoverPass, NewBook, or Firefly to confirm Average Daily Rate (ADR) and monthly occupancy rates.

2. Recasting Operating Expenses

Sellers frequently omit or downplay critical operating expenses. Ensure your underwriting accounts for:

• True Management Costs: If the seller currently manages the park for free, add a replacement management fee (typically 8% to 12% of gross revenue).
• Property Tax Re-assessment: Taxes will likely adjust upwards based on your new purchase price. Contact the local county assessor to calculate the post-closing ad valorem tax burden.
• Utility Submetering & Trash Disposal: Verify whether electric usage is submetered to long-term guests or absorbed by ownership as an uncapped utility expense.

Pro Tip: Use our interactive RV Park Deal Calculator to stress-test your Net Operating Income (NOI), Debt Service Coverage Ratio (DSCR), and capitalization rates.

4. Physical Infrastructure & Utility Diligence

Subterranean utilities represent the single largest capital risk in campground acquisitions. Inspect each critical system thoroughly:

Electrical Distribution Grids

Modern RVs (especially large Class A diesel pushers and fifth wheels) feature multiple 15,000 BTU air conditioners and onboard laundry, demanding consistent 50-Amp service.

• Transformer Capacity: Hire a licensed master electrician to perform a panel audit and verify transformer kVA sizing with the local electrical cooperative.
• Pedestal Condition: Inspect pedestals for burnt lugs, undersized wiring, open grounds, or missing breaker covers.
• Pedestal Ratio: Audit the exact ratio of 50-Amp, 30-Amp, and standard 20-Amp sites. Properties with primarily 30-Amp service require significant capital expenditures to upgrade.

Septic and Wastewater Infrastructure

• Municipal vs. Private Treatment: If connected to municipal sewer, verify lift station condition and municipal billing structures (impact fees vs. volume rates).
• Private Septic Systems & Lagoons: Order a commercial septic inspection including tank pumping, baffle inspection, and drainfield dye/load testing. Request historical state environmental permitting records.
• Grease Traps & Dump Stations: Verify dump station holding capacity and state discharge compliance.

Water Supply & Distribution

• Public Water Systems (PWS): If the park operates a private well serving 25+ individuals daily for over 60 days per year, it is classified as a public water system by state authorities.
• Testing & Pressure: Review the last 3 years of water quality test logs for coliform, nitrates, lead, and heavy metals. Verify static and dynamic water pressure at the furthest pedestal during peak morning hours.

5. Zoning, Permitting & Legal Verification

Legal non-conformity is a pervasive issue in campground investments. A park built decades ago may operate under conditions that violate modern county zoning ordinances.

1. Zoning Verification Letter (ZVL)

Never assume a valid business license equals proper zoning. Request an official Zoning Verification Letter from the city or county planning department to confirm:

• The exact zoning classification (e.g., Commercial Recreation, Agricultural, C-3, R-4).
• Permitted site density (maximum allowed sites per acre).
• Whether expansion or adding glamping units, cabins, or storage yards is legally permitted.

2. Legal Non-Conforming ("Grandfathered") Risks

If the park operates under grandfathered status, clarify the rebuild clause:

• What happens if a flood, wildfire, or hurricane damages more than 50% of the property? In many jurisdictions, grandfathered rights terminate upon substantial casualty loss, preventing full reconstruction.

3. Environmental Site Assessment (Phase I ESA)

Order a standard ASTM E1527 Phase I Environmental Site Assessment to ensure:

• No historical underground storage tanks (USTs) or legacy fuel pumps are leaking on the property.
• No neighboring industrial runoff or pesticide dumping threatens the park's soil or groundwater.

6. Operational, Staffing & Workamper Assessment

• Workamper Agreements: Review existing workamper contracts to verify hours required per week (typically 15–20 hours) in exchange for free site rent, electricity, and hourly pay.
• Reservation Software Transfer: Verify if the current Property Management System (PMS) contract can be assigned to the buyer or if a new platform setup is required.
• Vendor Contract Transfers: Audit waste disposal, propane supply, laundry lease, and Wi-Fi service agreements.

8. Fatal Due Diligence Red Flags to Watch Out For

1. Unverifiable Cash Receipts: P&L statements reporting income that does not appear on filed tax returns or bank statements.
2. Septic Absorption Field Failure: Saturated soil, standing water, or unpermitted septic expansions.
3. Severe Voltage Drops: Transformer capacity unable to maintain 110V+ per leg under peak summer electrical load.
4. Zoning Non-Conformity Without Rebuild Rights: Lack of written protection allowing reconstruction after natural casualty events.
5. Private Access Road Encroachments: Ingress/egress traversing neighboring property without a deeded commercial easement.

9. Frequently Asked Questions

How long should an RV park due diligence period be?

Typically 45 to 60 days. Subterranean utility testing, environmental Phase I studies, and municipal zoning verification letters require at least 30 to 45 business days to complete.

What is the most expensive due diligence mistake?

Failing to test subterranean utilities (septic drainfields and electrical transformers). Replacing an inadequate septic system or upgrading an electrical grid can easily cost $100,000 to $350,000+.

Can I perform due diligence before having an accepted contract?

No. Comprehensive due diligence requires access to private tax returns, bank records, and on-site engineering testing, which sellers will only grant under an executed Purchase and Sale Agreement (PSA) with an earnest money escrow deposit.
