Building a book from scratch takes years. Buying one takes months. For agents who want to skip the startup phase and immediately have clients, revenue, and carrier production — acquiring an existing book is the fastest path.
But book acquisitions can also go wrong. Overpay, lose half the clients in year one, and you're underwater. This guide covers how to do it right.
Step 1: Find Books for Sale
Insurance books of business become available for several reasons:
- Retirement — The most common. Agents aged 55+ with no succession plan.
- Career change — Agents leaving the industry
- Health issues — Agents who can no longer service clients
- Agency consolidation — Larger agencies selling off unprofitable segments
Where to find them:
- Industry marketplaces: Agency Equity, BizBuySell, Insurance Journal classifieds
- Aggregator networks: Your aggregator often knows of retiring agents in the network
- Carrier representatives: Carrier reps know which agents are planning exits
- Direct outreach: Contact agencies in your target market and ask if they're considering selling
- Professional networks: PIA, IIABA, Big I chapter meetings
Step 2: Evaluate the Book
Not all books are created equal. Before making an offer, analyze:
- Revenue: Total written premium and commission income (last 3 years)
- Retention rate: Books with 85%+ retention are gold. Below 75% is a red flag.
- Carrier mix: Is the book concentrated in one carrier (risk) or diversified?
- Lines of business: Personal lines, commercial, or mixed? Commercial books typically command higher multiples.
- Client demographics: Are clients aging out? Growing? In a stable industry?
- Geographic concentration: Hyper-local books are easier to service but riskier (single-catastrophe exposure)
- Agent dependency: How personal is the relationship? Will clients follow the book or follow the agent?
Step 3: Value the Book
The standard valuation method is a multiple of annual commission revenue:
- Personal lines: 1.5x–2.0x annual commission
- Commercial lines: 2.0x–2.5x annual commission
- Mixed book: 1.75x–2.25x annual commission
- High-retention, diversified: Premium end of range
- Low-retention, concentrated: Low end of range or below

Step 4: Due Diligence Checklist
Before signing anything, verify:
- ✅ 3 years of commission statements (actual carrier reports, not self-reported)
- ✅ Retention rates by year and by carrier
- ✅ Loss ratio data (high loss ratios can trigger non-renewal by carriers)
- ✅ E&O claims history (any pending or past E&O claims?)
- ✅ Carrier appointment status (are all appointments in good standing?)
- ✅ Client list with premium, carrier, and renewal dates
- ✅ Pending cancellations or non-renewals
- ✅ Any existing non-compete agreements
- ✅ Technology and data — how are client files stored? What transfers?
- ✅ Staff — are any employees included in the sale? Do clients know them?
Step 5: Structure the Deal
Most book acquisitions use one of these structures:
- Asset purchase: You buy the book (client policies), not the business entity. Most common and cleanest.
- Stock/entity purchase: You buy the agency itself, including its entity, appointments, and liabilities. More complex but sometimes necessary for carrier appointment transfer.
- Earn-out: Part of the price is paid based on how much of the book retains. This protects the buyer from attrition risk.
Common deal structure: 20–30% down payment, balance financed by the seller over 3–5 years, with an earn-out component tied to retention.
Step 6: Transfer Carriers and Policies
This is the most complex part of the acquisition. Each carrier has its own process for transferring a book of business. Expect:
- Carrier approval of the new servicing agent
- Updated agency agreements and appointments
- Commission transfer documentation
- AMS/system data migration
- Timeline: 30–90 days per carrier
Aggregator advantage: If both the seller and buyer are with the same aggregator, carrier transfers are dramatically simpler — the appointments don't change, only the servicing agent does.
Step 7: Retain the Clients
The acquisition isn't successful until you've kept the clients. Retention strategy starts before the deal closes:
- Seller introduction: The selling agent personally introduces you via letter, email, and ideally phone calls to top clients
- Personal outreach: Call every client within the first 30 days. Don't try to sell — just introduce yourself and listen.
- Service continuity: Keep the same phone number, office location, and staff if possible
- Quick wins: Identify clients who are overpaying or underinsured and offer immediate value
- Review appointments: Schedule annual reviews with every client in the first 6 months
Financing Options
- Seller financing: Most common. Seller carries a note over 3–5 years at 4–8% interest.
- SBA loans: SBA 7(a) loans work for book acquisitions. Typical terms: 10-year repayment, 10–20% down.
- Bank loans: Some banks specialize in insurance agency lending (Live Oak Bank, IFIC).
- Personal savings: The simplest option if you have the capital.
- Aggregator programs: Some aggregators offer acquisition financing or assistance to their agents.
Red Flags to Watch For
- 🚩 Retention below 75% — there's a reason clients are leaving
- 🚩 Single-carrier concentration above 50% — one carrier exit destroys the book
- 🚩 Seller unwilling to do client introductions — clients won't stay without a warm handoff
- 🚩 High loss ratios — carriers may non-renew after the acquisition
- 🚩 No written records — if the seller can't produce clean financials, walk away
