Should I buy the building my business operates from?

Buying the building a business operates from converts rent into mortgage principal and depreciation, adds a second income stream if there are tenant suites, and anchors the location — but it adds debt, and only a stable business should add debt. The decision is a cash-flow model, not a tax decision: price, down payment, debt service, operating costs, and the depreciation benefit, each modelled in more than one scenario.

Key points

Buying the building a business operates from is a cash-flow and stability decision first; the depreciation benefit is real but secondary.
Rent paid to a landlord is gone, while the same payment on an owned building builds equity and generates depreciation deductions.
A purchase adds mortgage debt, so it suits a business with stable, predictable cash flow rather than one with lumpy revenue.
The building is usually held in a separate entity that leases to the operating company at market rent, which brings the self-rental rules into play.
The decision should be modelled across a good year, a flat year, and a downturn before any purchase is made.

What is the case for buying your building?

Every rent payment made to a landlord is gone; the same payment made on a mortgage the owner holds builds equity in an appreciating asset. Owning the building also lets the property depreciate, generating deductions claimed on Form 4562, and a cost segregation study can accelerate those deductions on the shorter-lived components such as finishes, specialised systems, and site improvements.

If the building has more space than the business needs, leasing the extra suites adds a second income stream. Owning the location also anchors the business, protecting it from a landlord raising the rent or refusing to renew after the owner has invested in fitting out the space. For a medical or dental practice with expensive build-outs, that protection alone can justify a purchase.

What is the case against buying?

The case against buying is debt and commitment. A purchase almost always means a commercial mortgage, and debt is only safe for a business with stable, predictable cash flow. A business with lumpy or uncertain revenue can find a fixed mortgage payment dangerous in a slow year, whereas a lease can sometimes be exited or subleased.

Owning also ties up capital in the down payment and closing costs that might otherwise fund growth, and it makes the owner responsible for maintenance, property taxes, insurance, and vacancy in any tenant suites. A business that may relocate, merge, or sell within a few years should be cautious, because a building is far less liquid than the practice inside it.

How should ownership be structured?

The sound structure is usually to hold the building in a separate entity from the operating business and have the operating company lease it at a documented market rent. That separation protects the real estate from claims against operations and keeps the depreciation and rental income cleanly organised.

When the same people own both entities, the self-rental rules under the passive-activity regulations govern how the rental income is treated: net rental income from property leased to a business in which the owner materially participates is recharacterised as non-passive, so it cannot be sheltered by passive losses from other properties. An attorney drafts the entity and the lease; a CPA applies the self-rental and depreciation rules to the numbers.

How do you make the decision?

Because this is a cash-flow decision, it should be settled with a model, not a hunch. Lay out the purchase price, the down payment, the monthly debt service, the operating costs of ownership, the depreciation benefit, and any income from leasing extra space. Then run it in more than one scenario: a good year, a flat year, and a downturn.

If the business can comfortably carry the building through a bad year, ownership is likely a strong long-term move. If a slow year makes the payment frightening, leasing is the wiser choice for now. Buy the building because the numbers hold up under pressure and the business is stable, not because someone described the depreciation as the reason.
