The short answer: A PropCo/OpCo structure places a business's real estate in one entity (the property company) and its operations in another (the operating company), connected by a lease. Done well, it can isolate assets, create separate financing and sale options, and clarify performance. But the separation is only as real as the rent, guarantees, governance, and day-to-day conduct behind it. Two LLCs on a chart protect nothing by themselves.

One Business, Two Assets, Two Risk Profiles
The rent you pay yourself today may become the lease a buyer underwrites tomorrow.
An owner tends to think of the store, the shop, the dealership, the clinic, and the building it sits in as one business. Capital markets do not. They see an operating enterprise and a real estate asset, with different risks, different buyers, different lenders, and different valuation methods. The business is worth a multiple of its cash flow. The building is worth its rent divided by a cap rate. Those are separate markets, and the owner who understands that has more options than the one who does not.
In the structure, PropCo owns the land and improvements. OpCo employs the people, signs the customer and vendor contracts, owns the equipment and inventory, and pays rent to PropCo. The chart is easy. The chart is also the least important part.
What the Structure Actually Looks Like
Picture an owner or holding company at the top, with two sibling entities below it: PropCo on one side, OpCo on the other, and a lease running between them.
PropCo typically carries the mortgage and, depending on the lease, some or all of the taxes, insurance, and structural obligations. OpCo pays rent and operating expenses, and may guarantee PropCo's debt or the lease. Cash moves between the two through documented rent, distributions, intercompany loans, or capital contributions, not through one shared bank account.
The lease is what makes the structure real. It sets term, rent, escalations, renewal options, assignment rights, permitted use, maintenance allocation, casualty and condemnation treatment, and default remedies. Everything in the NNN lease explainer applies here, with one difference: you are on both sides of the table, which is precisely the problem.
One distinction to keep clean. An internal PropCo/OpCo lease keeps both entities under common ownership. A third-party sale-leaseback moves PropCo ownership outside the group entirely while OpCo remains the tenant. The internal structure is often the preparation for the external transaction.
Why Operators Separate Them
Risk organization. A long-lived asset with its own records and ownership sits apart from ordinary operating liabilities: a slip-and-fall, a vendor dispute, an employment claim. This is subject to formalities, guarantees, liens, insurance, and state law, and it is a lot less automatic than the diagram implies.
Financing. Property debt can be underwritten to collateral value and rent coverage, while working-capital or acquisition debt is underwritten to OpCo cash flow. Two lenders, two sets of terms, and often more total capacity than one blended loan. Cadwalader's explanation of OpCo/PropCo financing lays out how lenders think about the split.
Succession. Heirs or partners can receive different interests in the real estate and the operations. The child who runs the business gets OpCo; the one who does not gets a share of PropCo and a rent check.
Transaction flexibility. Sell OpCo and remain landlord. Sell PropCo and keep operating. Sell both to different buyers. Refinance one without touching the other. Bring in a partner on one side only.
Management clarity. Separating the real estate return from the operating return shows whether the business is actually good or just occupying a building rent-free.
And the caution that belongs next to every one of those: separation does not automatically create tax savings, bankruptcy remoteness, or liability protection. It creates the possibility of them, conditioned on everything below.
Rent Is the Hinge Between the Companies
Every benefit above runs through one number.
Set rent too low and PropCo's economics are understated, its financing capacity shrinks, and the arrangement can be difficult to defend as arm's length. Set rent too high and value is extracted from OpCo, fixed-charge coverage weakens, and the business appears healthier before rent than it actually is after.
The standard is what unrelated parties would agree to for comparable property under comparable circumstances. That is the arm's-length principle in 26 CFR 1.482-2(c), and the IRS's guidance on rent deductibility makes the same point in plainer terms: rent between related parties has to be reasonable to be treated as rent.
Here is the valuation tension that makes rent matter beyond tax. Business buyers typically value OpCo on EBITDA or cash flow after a normalized occupancy cost. Property buyers capitalize sustainable market rent. Inflating rent moves value toward PropCo, but it does not create durable combined value, because each buyer will correct toward market from its own side.
A Worked Value Split: Market Rent vs. Over-Rent
Hypothetical and illustrative. An operator generates $1,200,000 of earnings before occupancy cost and owns its $5,000,000 building. Assume business buyers pay 5x EBITDA and property buyers pay a 7% cap on market rent.
| Line | Market-rent lease | Over-rented lease |
|---|---|---|
| Earnings before occupancy | $1,200,000 | $1,200,000 |
| Rent | $350,000 (7% on $5.0M) | $450,000 |
| OpCo EBITDA | $850,000 | $750,000 |
| Fixed-charge coverage (earnings ÷ rent) | 3.4x | 2.7x |
| OpCo value at 5x, as reported | $4,250,000 | $3,750,000 |
| PropCo value at 7% cap, as reported | $5,000,000 | $6,430,000 |
| Naive combined value | $9,250,000 | $10,180,000 |
The naive math says over-renting created $930,000. It did not.
A property buyer who does its homework will not pay a 7% cap on rent that is $100,000 above what the building could fetch from anyone else. It will capitalize market rent normally and either haircut the excess sharply or widen the cap rate on the whole stream. A business buyer, meanwhile, will normalize occupancy cost to market when it computes EBITDA, so OpCo's value returns to roughly $4,250,000 regardless of what the internal lease says, except that the buyer now also has to price a lease obligation $100,000 above market for its remaining term, which it will discount for.
What the over-rent actually did is sell $100,000 a year of OpCo's future cash flow, for twenty years, to whoever buys PropCo, and hand OpCo a thinner cushion (2.7x instead of 3.4x coverage) for a downside year. The present value of that $100,000 stream at 8% over twenty years is roughly $980,000. The operator did not create $930,000. It pre-sold about $980,000 of future earnings and weakened the business in the process. Add transaction costs and taxes on each side, which this table ignores, and the trade gets worse.
The Lease You Write to Yourself Must Work for a Stranger
A lease that works only while both sides have the same owner is not transaction-ready. Draft the internal lease as if a third party will own one side of it someday, because one probably will.
- Set market-supported base rent and defensible increases, and keep the evidence (comparable leases, an appraisal, a broker opinion).
- Match the term to the business's realistic need for the site. A 20-year lease on a location the concept may outgrow in seven is a liability.
- Allocate roof, structure, systems, taxes, insurance, and environmental obligations explicitly. Silence on these items is fine while you own both; it is a fight when you do not.
- Preserve assignment and change-of-control flexibility so a business sale does not require landlord consent you may no longer control.
- Address alterations, expansion, signage, access, and permitted use.
- Define casualty, condemnation, purchase options, renewals, defaults, and cure rights.
- Document any guarantees and lender subordination without collapsing the separation you are trying to create.
- Keep signed amendments, payment records, tax reporting, insurance certificates, and separate bank accounts. Actually pay the rent, on time, from the right account.
What Lenders and Buyers Look Through
The entity chart shows two boxes. Lenders and buyers look for the wires that reconnect them.
Cross-defaults, where a default under OpCo's loan or lease triggers a default under PropCo's mortgage. Cross-collateralization, where PropCo's real estate secures OpCo's line of credit. Upstream or downstream guaranties, where one entity backs the other's obligations. Cash sweeps that pull OpCo's cash to service PropCo debt. Shared services with no allocation agreement. Transfer restrictions that make one entity unsellable without the other. And related-party rent, which is the first thing every buyer normalizes.
Each of those can be perfectly sensible. Each also reconnects a risk the chart appears to separate. The practical diligence question, from either buyer's side, is: which entity owns the cash, the permits and licenses, the intellectual property, the fixtures and equipment, the environmental obligations, and the replacement liability for the roof? If the answer is "we never really decided," that is what the buyer will price.
What Can Break the Separation
Commingled funds. Undocumented transfers. Rent that stops getting paid when cash is tight. Shared contracts with no allocation. An undercapitalized PropCo or OpCo. Inconsistent records that describe the entities one way to the bank and another way to the insurer. Blanket guarantees or liens that expose PropCo's real estate to every OpCo obligation. A lease materially above or below market. Treating PropCo's building as though OpCo owns it, or skipping corporate formalities entirely.
Any of these can support a fraudulent-transfer, alter-ego, veil-piercing, or substantive-consolidation argument, or an IRS challenge to the rent, or a lender claim that the separation was never real. All of those are fact- and jurisdiction-specific and all require counsel.
The cautionary tale most practitioners point to is the HH Liquidation litigation from the Haggen grocery bankruptcy, where the bankruptcy court's findings of fact walk through how the property and operating entities were formed, funded, represented to creditors, and actually run. The lesson is not that PropCo/OpCo structures fail. It is that courts examine what the entities did, not what they were named.
How the Structure Changes a Future Sale
Sell OpCo, retain PropCo. You become a landlord with a third-party tenant, and the lease terms become part of the business negotiation. The buyer will push on rent, term, and assignment; you will want a guaranty from the new owner. The rent you set to yourself is now the rent a stranger is agreeing to pay, or not.
Sell PropCo, retain OpCo. This is the sale-leaseback. You monetize the real estate and take on third-party occupancy risk: a landlord who will enforce the lease, and a rent obligation that outlives the check.
Sell both. Separate pricing, separate buyers, coordinated closings, and one lease that both buyers have to accept. This tends to produce the highest combined value when the lease was drafted for strangers from the beginning, and the most friction when it was not.
Bring in partners. Growth capital can go into OpCo while the family keeps PropCo, or a real estate investor can recapitalize PropCo while operations stay closely held. Each requires the lease to survive scrutiny from someone who did not write it.
In every case, buyers will normalize rent, read every guaranty, trace every cross-default, and test whether OpCo can pay in a downside year. Prepare both entities years before a sale, not during diligence.
The place I see this go wrong most often is the operator who has been running a thoughtful PropCo/OpCo structure for a decade and has never once amended the lease. Rent has not changed since 2016, the term expired three years ago and nobody noticed, and the roof was replaced by OpCo even though the lease says PropCo. None of that mattered while one person owned both. All of it matters the day a buyer or lender opens the file.
Separation Creates Options Only When It Is Real
PropCo/OpCo is not a diagram for a tax return. It is a long-term allocation of assets, cash flow, control, and risk. Price the rent honestly, document the relationship, and preserve the flexibility you expect to use. Done well, separation gives an operator more ways to finance, hold, or sell. Done casually, it gives a future buyer more places to find a problem.

Frequently Asked Questions
What do PropCo and OpCo mean? PropCo is the property company that owns the real estate. OpCo is the operating company that runs the business and leases the property from PropCo. They are usually sibling entities under common ownership, connected by a lease.
Does separating the real estate protect it from business creditors? It can help, but it is not automatic. Protection depends on maintaining the entities as truly separate (separate accounts, documented rent, adequate capitalization, formalities), on the absence of cross-guarantees and liens, and on state law. Courts and creditors can look through a separation that exists only on paper.
How should related-party rent be set? At what unrelated parties would agree to for comparable property, supported by evidence such as comparable leases, an appraisal, or a broker opinion. Rent well above or below market invites tax challenge, weakens one entity's value, and gets normalized by any buyer or lender.
Can the property be sold without selling the operating business? Yes. That is a sale-leaseback: PropCo (or the property) is sold to an investor and OpCo stays as tenant under the existing or a new lease. Whether the sale goes well depends heavily on whether that lease was drafted to work for a third-party landlord.
