Owner-occupied manufacturing isn’t a strip mall. Yet many models treat the plant as “redundant” real estate and plug in a market rent to make the operating company look comparable to peers. That shortcut can double-count risk and misprice value by 10–30% in special-use settings. If your production depends on power, clear heights, crane rails, line layout, or employee commute patterns, your building is part of the operating engine—not a separable investment property.
When the shortcut breaks
Market rent assumes the site is easily swappable. In manufacturing, that assumption fails when: (1) Utility fit is unique (power, water, air, cranes, dock/clear height). (2) Switching costs are real (downtime, re-qualification, audited processes, customer plant visits). (3) Yield/quality depend on layout tuning and labor stability. (4) Zoning or environmental constraints make replacement slow and expensive. In these cases, charging rent inside the OpCo model and also modeling plant capex and uptime penalties elsewhere is effectively counting the same risk twice.
What to do instead
Model the plant as integral. Remove internal rent from OpCo cash flows. Build maintenance and staged capacity capex directly into the operating forecast (with timing). Incorporate uptime/downtime risk explicitly in the DCF rather than hiding it in a rent line. Then cross-check the implied real estate value by triangulating: (a) the OpCo’s implied contribution margin and throughput; (b) a careful income cap for buildings with similar utility; and (c) $/sf comparables, adjusted for special-use features. You’re not ignoring real estate—you’re preventing internal rent from distorting performance and valuation.
Errors that quietly kill deals
• Double-count: applying market rent and still reserving plant capex.
• Wrong working-capital peg: ignoring throughput-tied inventory needs.
• Relocation fantasy: assuming zero downtime or re-qualification time.
• Borrowed cap rates: using generic industrial cap rates on special-use property.
• No environmental/condition reserve and no holdback for latent issues.
Negotiation moves that protect value
If you’re buying, bid inclusive of normalized working capital at cost with a true-up, and if inventory is “extra,” cap that at cost with a price-for-price reduction. Run the model both ways (integral vs redundant) for transparency; where utility is clearly special-use, anchor on the integral method. Lock a Phase I environmental, an appraisal or cap-rate support, the working-capital peg mechanics, and a 5–10% holdback for 12–18 months to cover latent repairs or environmental surprises.
Why this matters
Courts and buyers reward predictable cash. Treating integral property as redundant often inflates risk in two places and depresses value. Treating it correctly keeps the earnings quality narrative clean, reduces retrade risk, and aligns price with actual performance and transferability.
