Acquiring an irrigation installation business with $1M–$5M in revenue typically requires a blended capital stack. SBA 7(a) loans dominate lower middle market irrigation deals due to favorable terms and lender familiarity with outdoor services cash flows. Sellers often carry a note or equity rollover to bridge valuation gaps, particularly when recurring maintenance contracts—winterization, spring startups—drive a meaningful share of EBITDA. Expect purchase prices of 3x–5.5x SDE depending on recurring revenue mix and equipment fleet condition.

Financing Options for Irrigation Installation Acquisitions

SBA 7(a) Loan

$500K–$4.5MPrime + 2.25%–2.75% (currently ~10.5%–11%)

The most common financing vehicle for irrigation business acquisitions. Covers up to 90% of the purchase price, with lenders underwriting recurring maintenance contract revenue favorably as predictable cash flow.

Pros

Low 10% down payment preserves buyer working capital for seasonal cash flow gaps
Lenders familiar with outdoor services EBITDA and seasonal revenue normalization
Can finance goodwill, equipment fleet, and working capital in a single loan structure

Cons

×Personal guarantee required; collateral shortfall common when equipment is aged or leased
×Approval timelines of 60–90 days can complicate deals with motivated retiring sellers
×Lenders may stress-test high installation-revenue concentration if recurring contracts are under 25%

Seller Note

$100K–$600K6%–8% fixed, interest-only periods negotiable

Seller carries 10–20% of the purchase price as subordinated debt, often tied to customer contract retention milestones over 12–24 months post-close. Common in irrigation deals with key-man risk concerns.

Pros

Signals seller confidence in business continuity and smooths SBA lender approval
Retention-linked structure protects buyer if key maintenance accounts defect post-close
Flexible terms allow deferral during off-peak winter months when cash flow is tightest

Cons

×Seller may resist subordination required by SBA lenders, complicating deal structure
×Default risk if seasonal revenue underperforms in year one due to drought or weather events
×Requires clear legal documentation of contract retention thresholds and cure periods

Equity Rollover or Earnout

$100K–$800K in retained equity or earnout valueN/A (equity) or 0% with contingent payment triggers

Seller retains 10–20% equity stake or accepts an earnout tied to annual seasonal revenue targets. Common in PE-backed roll-up acquisitions where seller's contractor relationships and technician retention are critical.

Pros

Aligns seller incentives to support buyer through transition and retain key HOA and builder accounts
Reduces upfront cash requirement, improving buyer DSCR on senior debt
Attractive to PE roll-up platforms acquiring multiple irrigation businesses in suburban growth markets

Cons

×Earnout disputes common if seasonal weather suppresses installation revenue in measurement period
×Seller retaining equity complicates clean operational handover and decision-making authority
×Requires robust earnout language defining revenue, EBITDA, and contract retention metrics precisely

Sample Capital Stack

$2,000,000 (4x SDE on $500K EBITDA irrigation business with 35% recurring maintenance revenue)

Purchase Price

~$17,500/month on SBA loan at 10.75% over 10 years; seller note interest-only at $1,000/month

Monthly Service

~1.35x DSCR based on $500K EBITDA after $25K market-rate owner compensation add-back; within SBA lender comfort range

DSCR

SBA 7(a) Loan: $1,600,000 (80%) | Seller Note tied to contract retention: $200,000 (10%) | Buyer equity injection: $200,000 (10%)

Lender Tips for Irrigation Installation Acquisitions

1Separate recurring maintenance and winterization contract revenue from one-time installation revenue in your loan package — lenders underwrite the recurring portion at a premium and it materially improves your DSCR presentation.
2Document the equipment fleet with a current appraisal and maintenance logs. SBA lenders will scrutinize truck and trencher condition; aged or poorly maintained assets may trigger collateral shortfalls requiring additional equity.
3Show at least 3 years of tax returns with a detailed add-back schedule normalizing owner compensation, personal vehicle expenses, and seasonal labor spikes. Clean financials dramatically shorten underwriting timelines.
4If the seller's contractor license is required for operations, confirm transferability with your state licensing board before LOI. Lenders and attorneys will flag license continuity risk; a plan to obtain your own license pre-close strengthens the file.

Frequently Asked Questions

Can I use an SBA 7(a) loan to buy an irrigation business if I have no prior irrigation experience?

Yes. SBA lenders evaluate your management experience, financial strength, and the business's cash flow history. Hiring a licensed irrigation manager or retaining the seller during transition mitigates experience risk for lenders.

How does heavy seasonality affect SBA loan underwriting for an irrigation acquisition?

Lenders normalize seasonal revenue by averaging 2–3 years of annual EBITDA rather than monthly cash flow. Provide trailing twelve-month financials and a seasonal cash flow schedule to demonstrate the business covers debt service annually.

What percentage of recurring maintenance revenue do lenders want to see in an irrigation business?

Most SBA lenders prefer at least 25–30% of revenue from recurring contracts — winterization, spring startups, and maintenance agreements. Higher recurring revenue justifies stronger multiples and improves DSCR in underwriting models.

How does a seller note affect my SBA loan approval for an irrigation business acquisition?

SBA requires seller notes to be on full standby for 24 months. Lenders view a seller note positively as a confidence signal, but the note must be subordinated and cannot require principal payments during the standby period.
