What is captive insurance, and when does it make sense for your portfolio?
Learn how captive insurance works, how forming a captive differs from participating, and how to evaluate the costs, risks, capital, and potential benefits.

Insurance is usually something a property business buys from someone else. A captive changes that relationship: a business owns or participates in an insurance structure that takes on defined risks, rather than transferring all of those risks to an outside insurer.
That can create more control over how risk is financed. It also creates responsibilities—and the possibility of losses. For property owners and managers, the useful question is not “How much premium can we collect?” It is “Which risks can we responsibly retain, and does the structure improve our economics after every cost?”
What a captive actually does
A captive is an insurance company established to insure a defined set of risks associated with its owners or participants, within the rules that apply to its structure. It is not simply a reserve account or a new name for a property-management fee.
Premium funds claims, operating expenses, and other obligations. Capital provides a financial cushion. When results are favorable, some structures may allow owners or participants to share in the remaining economics. When claims are higher than expected, that cushion can shrink and additional funding may be required.
Captives are regulated. For example, Vermont’s captive regulator describes licensing, financial surveillance, and examinations as core responsibilities. The state where a captive is licensed—its domicile—is only one part of the legal analysis; where risks and insured parties are located matters too.
Forming your own captive is not the same as participating
A standalone captive generally means creating and owning a separate insurer. The business must arrange licensing, capital, governance, underwriting, claims administration, accounting, and ongoing regulatory compliance. Specialists can perform much of the work, but outsourcing does not eliminate the owner's responsibilities.
Participation in an existing structure can use infrastructure already provided by a sponsor or group. A protected-cell arrangement, for example, can separately account for a participant's business within a sponsored captive. Vermont’s protected-cell statute provides specific rules for separating assets and liabilities and approving participant contracts.
That does not mean every participation program provides identical protection. Ask what you own, which losses you bear, whether there is shared risk, and what happens if another participant or the sponsor fails. Contractual participation, ownership, and eligibility for distributions are different things.
Follow the risk—not just the premium
Start with a diagram showing who issues coverage, pays claims, and ultimately bears losses.
Some programs use an outside insurance company to issue policies and transfer an agreed share of risk to a captive through reinsurance. That issuing company is often called a fronting carrier. Other arrangements work differently. Reinsurance is insurance purchased by an insurer; it does not make the underlying risk disappear.
Identify the retained layer, deductibles, exclusions, per-claim limits, and annual aggregate protection. Ask who covers a severe year, what collateral secures obligations, and whether funding requirements can increase. A letter of credit may tie up borrowing capacity even when cash has not left your bank account.
If the proposal involves resident-facing coverage, evaluate the underlying product separately. A captive financing arrangement does not determine what a resident's policy covers. Review coverage, exclusions, and resident obligations before evaluating any captive participation.
When the idea deserves a closer look
A feasibility review is more useful when a portfolio has reliable claims history, consistent operating practices, and a willingness to commit capital for multiple years.
Look for risks you can measure and influence: better maintenance, clearer incident reporting, or more consistent claims documentation. Consider concentration too. Many buildings exposed to the same storm or regional disruption may produce losses together, rather than diversify them.
There is no universal door-count threshold. Expected premium, loss volatility, geography, coverage design, available capital, and fixed expenses all affect feasibility. A portfolio can be large enough to attract a proposal without being a good fit for that proposal.
Model the downside before the upside
Consider this simplified, hypothetical annual model—not a quote or forecast:
- Premium allocated to the captive: $500,000.
- Expected claims and claims-handling costs: $250,000.
- Other expenses, including administration and purchased risk protection: $150,000.
- Remaining underwriting result: $100,000, before taxes and other adjustments.
If claims and claims-handling costs instead reach $450,000, that same model produces a $100,000 loss. Separate startup costs, required capital, collateral, and the cost of tying up that capital still need to be modeled.
A positive result is not automatically distributable cash. Claims may develop later, reserves may need strengthening, and contracts or regulators may restrict distributions. Vermont, for example, requires regulatory approval for captive dividends.
For a property manager, also establish who receives any economic benefit: the management company, property owner, or another participant. Do not count the same benefit twice. Separate program revenue from actual take-home economics, including incremental operating expenses.
Questions to ask before committing
Request a complete fee schedule, including formation, management, actuarial, audit, legal, fronting, reinsurance, claims, and termination costs. Ask which costs are fixed and which change with premium or losses.
Then ask who approves underwriting changes, controls claims decisions, reviews reserves, and handles conflicts of interest. Request adverse-loss scenarios and a written explanation of additional funding obligations.
Finally, ask about exit. Ending new business does not end responsibility for old claims. Runoff administration, continuing collateral, and delayed capital release can make departure slower and more expensive than expected.
Start with fit, not a promise
A captive should solve a risk-financing problem—not manufacture a return assumption. Contact Goodcover to discuss your portfolio's goals and the questions worth asking next.
Frequently asked questions
Does a captive guarantee profit?
No. It retains insurance risk. Favorable results depend on claims, pricing, expenses, and other factors, and losses can consume capital.
Is the main benefit a tax break?
Do not build the decision around assumed tax savings. Tax treatment depends on the facts and structure. Get independent insurance, legal, actuarial, and tax advice before committing.
Can participation be simpler than forming an insurer?
It can reduce setup work, but it does not remove contractual risk, funding obligations, or the need for independent review.
