Holding Company vs Operating Company: The Right Structure for Mobile Home Park Owners

As mobile home park owners grow from one park to two, three, and beyond, the question of how to structure the overall enterprise becomes more pressing — and more consequential. The entity you buy the first park in may be adequate for simplicity, but it rarely remains the right structure as you scale.

The holding company / operating company structure — often called HoldCo/OpCo — is the architecture that most sophisticated MHP portfolio operators eventually move toward. It is not just a liability tool. It is a framework that enables cleaner per-property financials, reduces self-employment taxes, creates deductible management fees, and creates the separation that institutional lenders and institutional partners expect.

This post explains how the HoldCo/OpCo structure works for MHP owners, why each component exists, how cash flows through it, and the mistakes that undermine it.

The Problem With Owning Everything in One Entity

Many MHP operators start by putting everything in a single LLC — park ownership, management, payroll, all expenses, all revenue. It is the simplest starting point. It becomes a problem as the portfolio grows.

If you own three parks in one LLC and face a significant liability at one park — an environmental issue, a personal injury judgment that exceeds insurance coverage, a contract dispute — that liability has access to the assets of all three parks. A single LLC offers no inter-park liability protection. The parks are not separate; they are just different revenue streams of the same entity.

Beyond liability, a single-entity structure makes clean per-property reporting essentially impossible. Lenders underwriting a specific park want to see that park’s NOI, that park’s expenses, that park’s debt coverage — not a blended picture of three parks combined. If you ever want to sell one park individually, bring in a partner on a specific asset, or do a 1031 exchange, a single-entity structure creates obstacles at every step.

And from a tax perspective, a single LLC treating all management activities and rental income the same way misses significant planning opportunities — particularly around self-employment tax, management fee deductibility, and S-Corporation elections.

The HoldCo/OpCo Structure Explained

The holding company / operating company structure separates three distinct functions into three distinct tiers:

Tier 1 — The Holding Company (HoldCo). This entity — typically an LLC — owns the membership interests of each park-level entity. It does not operate anything directly. It holds the ownership interests in the parks and may also hold other investment assets. The HoldCo provides an extra layer of liability separation: a claim against a specific park cannot directly reach the HoldCo’s assets (the ownership interests in other parks) without piercing two layers of entity protection.

Tier 2 — The Park-Level LLCs. Each mobile home park is owned by its own separate LLC. This LLC holds title to the real property, the park-owned homes, and the park’s specific assets. All income and expenses specific to that park flow through its LLC. The park-level LLC is what lenders see when they underwrite debt on a specific property — clean, property-specific financials. Each park-level LLC is owned by the HoldCo (or by investors and the HoldCo in co-investment structures).

Tier 3 — The Management Company (OpCo). This entity employs the staff, manages day-to-day park operations, and charges each park-level LLC a management fee for services rendered. The OpCo may be structured as an S-Corporation or an LLC taxed as an S-Corporation, which enables the owner to receive a combination of reasonable W-2 compensation and S-Corporation distributions — reducing self-employment tax on the distribution portion.

How Cash Flows Through the HoldCo/OpCo Structure

Understanding the cash flow path is essential for maintaining the structure correctly. Here is how money moves in a properly functioning HoldCo/OpCo setup:

Lot rent and POH rental income flows into each park-level LLC. The park pays its operating expenses — including the management fee to the OpCo, debt service, property taxes, insurance, utilities, and maintenance. After expenses, the park-level LLC has net operating income that is distributed to the HoldCo (its member) or retained.

The management company (OpCo) receives management fee income from each park-level LLC it manages. Out of those fees, it pays its employees (including the owner-operator’s reasonable salary), employment taxes, benefits, and its own operating expenses. Remaining profit at the OpCo level flows as S-Corporation distributions if the OpCo is an S-Corp.

The HoldCo receives distributions from the park-level LLCs. It may deploy that cash for new acquisitions, distribute it to the owner, or hold it as a reserve. The HoldCo’s ownership interests in the parks are what investors acquire when they invest at the entity level rather than at the park level.

The S-Corporation Election at the Management Company Level

The management company’s tax structure is one of the most financially significant decisions in the HoldCo/OpCo architecture. A management company taxed as a sole proprietor or a single-member LLC disregarded entity pays self-employment tax on all net income. A management company that elects S-Corporation status allows the owner to split income between W-2 wages (subject to payroll taxes) and S-Corporation distributions (not subject to SE tax).

The IRS requires that S-Corporation owner-employees receive “reasonable compensation” — a bona fide salary that reflects the fair market value of their services. This is not optional and it is a frequent IRS audit target in S-Corporation examinations. The reasonable compensation standard for an MHP operator who actively manages multiple parks, handles capital allocation decisions, and oversees staff must be set at a level that the IRS would find defensible — typically based on what you would pay a qualified manager to perform those functions.

The SE tax savings from the S-Corporation structure can be significant for operators with substantial management income, but they come with real compliance costs: quarterly payroll tax deposits, W-2 filing, potentially a separate payroll service, and the ongoing need to document reasonable compensation. Whether the savings exceed the compliance costs depends on the level of management income. Your MHP tax advisor should model the breakeven before you make the election.

Common Mistakes That Undermine the Structure

The HoldCo/OpCo structure is only as effective as the care with which it is maintained. These are the most common structural mistakes we see at The MHP Accountant®:

No written management agreement. The management fee arrangement between the OpCo and each park-level LLC must be documented in a written management agreement that specifies the services provided, the fee amount or formula, and the payment terms. Without a written agreement, the management fee is difficult to defend as a legitimate business expense, and the IRS may treat it as a distribution rather than a deductible expense.

Management fees not at arm’s length. The fee charged by the OpCo to the park-level LLCs must be reasonable — comparable to what third-party property managers would charge for similar services. If the fee is set at a number that simply sweeps all income from the park-level LLC into the management company, the IRS will scrutinize it. If the fee is unreasonably low, the SE tax planning benefit is reduced. Get the fee right and document the comparable rates in your market.

Commingling personal expenses at the management company level. The OpCo’s books must be clean. Personal expenses — owner’s personal travel, personal vehicle costs, family expenses — must not flow through the management company. The IRS examines S-Corporations carefully and the management company, as the most active operating entity in the structure, is subject to audit risk. Clean books protect the structure.

Failing to maintain separate bank accounts at each level. The HoldCo, each park-level LLC, and the management company must each have their own bank accounts with no commingling. Cash moving between entities must be documented as management fees (with invoices), loans (with promissory notes), or distributions (with proper authorization and recordkeeping). Informal cash transfers between entities in the same structure are a piercing risk.

Not updating the structure as the portfolio grows. A structure appropriate for two parks may need revision at five or ten parks. Adding new parks to the portfolio should be a structured event — new park-level LLC, new management agreement, updated HoldCo operating agreement to reflect the new park. Your MHP accountant should be involved each time you acquire a new park.

What Lenders See and Why It Matters

When you present a specific park to a lender, you should be able to hand them a clean set of financials for that park’s LLC — revenue, expenses, NOI, debt service coverage ratio — without any commingling from other parks or management activities. The HoldCo/OpCo structure enables this by design.

Park-level LLC financials that show management fees as an expense reflect a professional, institutional-quality operation. They also give the lender an accurate picture of NOI because they include the management cost that any buyer would face — making the financials more comparable and more credible than financials that show no management expense because the owner manages everything without a formal structure.
