The Difference Between a Captive, an RRG, and a Traditional Insurance Policy

If you have started researching alternative insurance structures for your real estate portfolio, you have almost certainly encountered three terms used inconsistently and sometimes interchangeably: traditional insurance, captive insurance, and Risk Retention Group. They are not the same thing, and the differences determine both what you can cover and how much of the underwriting profit you can capture.

This post gives you a clear side-by-side picture of all three: what each one is, who controls it, what it can cover, and where the profit goes.

Traditional insurance: the baseline

Traditional insurance is the structure virtually every real estate operator uses today. You pay a premium to a licensed carrier, companies like State Farm, Chubb, or a specialty habitational insurer. The carrier pools your premium with thousands of other policyholders, invests the float, pays claims when they arise, and keeps the underwriting profit.

You have no ownership stake in the carrier. You have no visibility into how your loss ratio compares to the pool. You receive no distribution of underwriting profit, regardless of how few claims you generate. At renewal, you may receive a modest pricing adjustment if you shopped aggressively, but the economics fundamentally favor the carrier.

Traditional insurance is not a bad product, it provides real protection. The problem is structural: it is designed to transfer wealth from policyholders to shareholders, and it does so reliably every year.

Captive insurance: turning the structure inside out

A captive insurance company is an insurance company owned by the businesses it insures. The premium still flows in. Claims are still paid. But the underwriting profit belongs to the owner: which is you, not a carrier's shareholders.

Captives can write virtually any line of coverage: property, liability, workers' comp, health, professional liability. This flexibility makes them the most comprehensive structure for operators who want to capture profit across all insurance layers simultaneously.

The primary limitation is formation complexity and capital requirements. A single-parent captive (one company creating its own insurance entity) typically requires $1–5 million in initial capitalization, legal formation, actuarial analysis, and ongoing regulatory compliance. This is why Fortune 500 companies and large hospital systems have used captives for decades while smaller operators have not.

The solution for most real estate operators is not a single-parent captive but a cell captive or protected cell company: a pre-established captive structure where participants operate in legally separate cells, sharing infrastructure and compliance costs while keeping their assets and liabilities segregated.

Risk Retention Group: the federally enabled alternative

An RRG is a specific type of captive created under the federal Liability Risk Retention Act of 1986. It is owned by its members, who must also be insureds. It is chartered in one state and can operate in all 50 under federal preemption.

The key advantage of an RRG over a traditional captive is regulatory efficiency: instead of navigating 50 state insurance departments, an RRG complies with the regulations of its single domicile state. This dramatically reduces the administrative burden and makes multi-state real estate operations far more practical.

The limitation: RRGs can only write liability coverage. Property insurance (fire, wind, physical building damage) cannot be written through an RRG under current federal law. This is why RRGs are typically paired with captive cells or traditional carrier property coverage in a full-stack real estate insurance program.

The side-by-side comparison

• Who owns it: Traditional: owned by external shareholders. You are a customer.

• Captive: owned by the insured businesses. You are an owner.

• RRG: owned by member-related insureds federal law. You are both insured and owner.

• Where profit goes: Traditional: carrier shareholders keep all underwriting profit.

• Captive: underwriting profit returns to the captive's owners (you).

• RRG: underwriting profit returns to the RRG's member-owners (you).

• Coverage scope: Traditional: property, liability, workers' comp, health or any line.

• Captive: property, liability, workers' comp, health or any line.

• RRG: liability only (GL, professional liability, EPLI, tenant liability, umbrella).

• Regulatory framework: Traditional: filed in each operating state, simple.

• Captive: regulated in domicile state, must comply with each operating state.

• RRG: regulated in one domicile state, federal preemption for all 50 states.

Which structure is right for a real estate operator?

The honest answer is: usually a combination of captives and RRGs.

The most efficient full-stack real estate insurance program looks like this: an RRG for liability lines (tenant liability, GL, D&O, EPLI) because of the regulatory efficiency and the federal preemption advantage across multi-state portfolios. A captive cell structure for property and workers' comp, capturing profit on those lines without RRG limitations. And traditional reinsurance for catastrophic stop-loss protection to eliminate downside risk in any component of the structure.

This is exactly how Insur3Tech is structured, combining both RRGs and captive cell mechanics to give operators access to underwriting profit across all three layers of a real estate portfolio, without requiring them to form their own insurance entity or navigate complex regulatory frameworks.
