Own vs Lease: How to Frame the Corporate Real Estate Decision
By Devon Coombs, CPA, MBA · Teaching Professor of Finance, Santa Clara University · Reviewed August 2026
Lease when the capital a building would tie up earns more inside the core business than it would as a real estate investment, which is the usual case for firms with strong returns on operating capital. Own when the incremental after-tax return on the ownership position clears the firm's real estate hurdle rate, or when control of a strategic facility justifies the capital. The decision is an investment choice about capital, not a comparison of rent to a mortgage payment.
| Own | Lease | |
|---|---|---|
| Economic substance | An incremental real estate investment by the firm | Occupancy cost; capital stays in the core business |
| Capital required | Equity tied up in the building | Little beyond deposits and improvements |
| Decision test | After-tax return on ownership vs the real estate hurdle rate | After-tax occupancy cost vs the cost of owning |
| Residual value and appreciation | Retained by the firm | Retained by the landlord |
| Tax treatment | Depreciation deductions; recapture at sale | Rent deductible on a true lease |
| Balance sheet treatment | Building and any mortgage debt on the balance sheet; book depreciation | Right-of-use asset and lease liability under ASC 842, a book effect rather than a tax one |
| Flexibility | Exit requires a sale or sale-leaseback | Options at expiry; renewal risk in exchange |
When Own is the right tool
Owning tends to make sense when the position clears the firm's real estate hurdle as a standalone investment: long expected occupancy, a facility so specialized that a landlord would price its risk heavily, or a site whose control carries strategic value. The analysis should credit ownership with depreciation, expected appreciation, and residual value, and charge it for the equity consumed and the property risk assumed. A firm holding space that no longer clears the hurdle on those terms can recover the capital through a sale-leaseback.
When Lease is the right tool
Leasing tends to win when the firm earns more on capital deployed in its own operations than a landlord earns on buildings, which is common for growing companies. Leasing also preserves flexibility at expiry and shifts residual value risk to the owner, which matters when future space needs are uncertain. Under a net lease the operating costs largely wash between the two options, so the comparison reduces to rent against the full economics of ownership.
The common mistake
The standard error is comparing this year's rent to this year's mortgage payment and concluding that owning is cheaper whenever the payment is lower. That framing ignores the equity the purchase consumes, the return that capital could earn in the core business, and the depreciation and residual value that belong in the ownership column. Framed correctly, owning is an incremental investment that must clear the firm's real estate hurdle rate on an after-tax basis. Firms that skip the test sometimes discover, usually at the point of a sale-leaseback, that they have been running a mediocre real estate fund inside a good operating business.
