When discussing industrial real estate with professionals in the technology sector, the most common question is: why not simply invest that capital in a low-cost stock index fund?
This is a highly logical question. Let us analyze the actual mathematical comparison.
The investment scenario
Assume you have $190,000 of capital to deploy. This represents a typical down payment on a first industrial acquisition: a $750,000 building requiring 25 percent down, with a commercial mortgage covering the balance.
Option A: $190,000 in a Stock Market Index Fund (VTSAX) over 10 years. Option B: $190,000 as a down payment on a value-add industrial building ($750k) over 10 years.
Index fund returns
Historically, the S&P 500 has returned an average of approximately 10 percent annually. Over ten years, a $190,000 investment would grow to roughly $493,000.
However, this figure does not account for taxes. Upon selling, you will owe long-term capital gains tax. Additionally, if your income exceeds the federal threshold, you will owe the 3.8 percent Net Investment Income Tax (NIIT). For high earners in California, this reduces the actual compounded return to roughly 7.5 to 8 percent.
The advantages of index funds are undeniable:
Zero active time required.
Instant liquidity.
Simple diversification.
No operational decisions.
If you do not want to dedicate time to sourcing and managing real estate assets, index funds are the correct choice.
Value-add warehouse returns
Applying that same $190,000 to an industrial building can yield a very different outcome. Imagine buying a property where existing tenants pay below-market rents, generating $3,500 per month on day one. Over the first 12 to 18 months, you stabilize the building at $7,250 per month gross rental income.
At stabilization: $87,000 gross rental income, $13,000 operating expenses (NNN), $74,000 NOI, $47,500 debt service, $26,500 net cash flow annually.
The depreciation tax shield
The IRS allows you to write down commercial buildings over a 39-year useful life. On a $750,000 property with 85 percent building improvements, your annual non-cash depreciation deduction is roughly $16,300. At a 37 percent marginal tax rate, this reduces your tax liability by approximately $6,000 annually while the asset generates real cash flow. Index funds do not offer this benefit.
The refinance event
Once stabilized, the building's value resets based on the new NOI. At a 7 percent cap rate, $74,000 NOI values the building at approximately $1,057,000. You can refinance at 70% LTV, withdraw roughly $180,000 in equity tax-free, and deploy it toward your next acquisition (or put it in an index fund) while continuing to own and collect cash flow from the first building.
Accessing equity from an index fund requires selling shares, which triggers immediate capital gains taxes.
The trade-offs
Illiquidity: Selling a commercial property typically takes 90 to 120 days and incurs 3 to 5 percent in transaction fees. If you may need your capital within two years, do not purchase real estate.
Active Management: Sourcing deals, overseeing renovations, and negotiating leases requires real work. The higher returns are direct compensation for this effort.
Deal Sourcing: You must invest the time to find properties with a genuine spread between current and market-rate rents in viable locations.
Industrial real estate is not a hands-off investment. However, for those willing to do the work, the after-tax financial advantages are compelling when compared directly to passive equities.
