What experienced industrial investors ask—and how to think about the answers

Pricing and returns

Is cap rate or IRR the right way to price a 10,000–100,000 SF building?

They answer different questions. A cap rate is a snapshot: documented net operating income divided by price, on a stated basis. An IRR is a hold-period story: what happens to that income through lease expirations, capital spending, financing, and a sale.

Smaller industrial buildings often have short leases, a few tenants, and rents that lag or lead the market. That makes the in-place cap rate easy to misread in either direction. Use both: price off income you can document, then model the hold lease by lease with explicit downtime, improvement, and commission assumptions, and an exit cap rate you can defend. Try the arithmetic in the investment guide’s cap-rate calculator.

How much weight should replacement cost carry?

Replacement cost—land, construction, soft costs, and lease-up—frames the downside. Buying well below what it would cost to build limits new competition at your rent level. It does not set value: a building with low clear height or a cramped truck court can be worth less than “cost” no matter what construction prices do.

Treat replacement cost as a sanity check on the price per square foot and on the competitive supply you should expect, not as a target. See building types and specifications for which features are fixable and which are permanent.

What does “below-market rent” really mean, and how do I underwrite the mark-to-market?

Only signed, comparable leases establish market rent, and in small-bay buildings the comparable set is narrow: suite size, office finish, door type, power, and yard rights all move the number. Treat broker asking rents as asking rents.

Then remember that rent only resets when a lease expires. Model each expiration with a retention probability, months of downtime, improvement costs, commissions, and any free rent. Do not pay for the upside in the price and count it again in the pro forma.

How should I set the exit cap rate and hold period?

The exit cap rate is usually the most sensitive assumption in the model, and the building will be older at exit than it is today. Many disciplined buyers refuse to assume an exit cap below the going-in rate without a specific reason such as a longer lease or a completed renovation.

Run sensitivities rather than a single case: a higher exit cap, lower market rent, longer downtime, and a delayed sale. If the deal only works in the base case, the base case is doing too much work.

Building and functionality

Does clear height matter for buildings this size, or only for bulk distribution?

It matters relative to the tenant pool. Service companies, contractors, light assembly, and last-mile operators in 10,000–40,000 SF spaces often care more about drive-in doors, power, office ratio, parking, and yard than about an extra few feet of clearance. Distribution users and third-party logistics tenants care about dock count, truck court, and racking height.

Buy for the users who will realistically lease the space, and underwrite rents for that pool. The building-fit checklist walks through what to measure on a tour.

What makes a Class B or C building “functionally obsolete,” and can capital fix it?

Some things capital fixes: roof, lighting, dock equipment, pavement, office refresh, electrical service, and sometimes adding dock positions. Some it cannot: low clear height, tight column spacing, a shallow truck court, high site coverage with no expansion land, and poor access. Those permanent features cap the rent the building can earn and narrow the future buyer pool.

Price the permanent limitations rather than planning around them, and keep in mind that a well-located, functional Class B building serving local demand can be a durable asset precisely because nobody builds its replacement.

How do I value excess land or an outdoor storage yard attached to a building?

Start with permission, not price. Confirm that the zoning and any approvals allow outdoor storage, trailer parking, or equipment staging; many municipalities restrict them even in industrial districts. Then verify legal access, surfacing, lighting, drainage and stormwater compliance, and whether the yard can be leased separately from the building.

Yard income with clear permission and separate leaseability is worth more than yard that is merely tolerated. The nine-county hub links the zoning authorities to ask.

Multi-tenant or single-tenant: which is less risky in this size range?

Multi-tenant buildings spread vacancy risk across several leases but bring more frequent rollover, demising and metering questions, and hands-on management. Single-tenant buildings are simpler to own and finance but carry binary vacancy risk and depend on one company’s health.

The better question is which risk you are equipped to manage. If you cannot lease and manage small suites efficiently, diversification on paper becomes vacancy in practice.

Tenants and leases

How do I underwrite tenant credit when the tenants are private companies?

Ask for what the lease allows: financial statements, payment history, time in business, ownership, and any guaranties or security. Then look past the financials to durability and stickiness: heavy equipment, permits, customer proximity, and specialized build-out make a tenant expensive to move.

In small-bay buildings, how easily a space re-leases often matters more than any one tenant’s credit. A functional suite in a liquid submarket is its own form of credit support.

Which lease clauses most affect value?

• Expense pass-throughs, especially whether real estate taxes after a reassessment are recoverable and whether CAM is capped.
• Roof, structure, HVAC, and pavement obligations—who replaces, not just who repairs.
• Renewal options at fixed or capped rents, which can cap your mark-to-market.
• Termination, contraction, assignment, and sublease rights.
• Hazardous materials, outdoor storage, trailer parking, and hours clauses that govern how the property may actually be used.
• Holdover, security, and guaranty terms.

Confirm all of it with tenant estoppels before closing. The lease-review checklist covers the mechanics.

How do I underwrite rollover and downtime realistically?

Build the model lease by lease rather than with a blended vacancy factor. For each expiration assign a retention probability, months of downtime if the tenant leaves, improvement and commission costs, and free rent. Then stress the schedule: two tenants leaving in the same year, a renewal at a lower rent, a longer lease-up.

Where rollover is concentrated, consider negotiating early renewals or extensions before closing—sellers often prefer certainty too.

In a sale-leaseback, what am I really buying?

Two things: the seller-tenant’s ability to pay rent for the lease term, and the real estate you would own if it stopped. The rent is often set by the seller’s financing need, not by the market, so test it against market rent to see how much residual risk sits in the building itself.

Lease term, guaranties, financial-reporting covenants, and maintenance obligations deserve the same attention as price. The selling guide explains the structure from the owner-user’s side.

Diligence and risk

When is a Phase I enough, and when do I need a Phase II?

A Phase I environmental site assessment identifies recognized environmental conditions from records, interviews, and a site visit; it does not sample. A Phase II samples soil, groundwater, or vapor when the Phase I, the building’s history, or the surrounding uses point to a risk. Lenders frequently require one when a Phase I flags conditions.

Budget calendar time for sampling and lab work, and understand the Illinois EPA Site Remediation Program and no-further-remediation letters before relying on them. The due diligence guide covers the process; EPA’s All Appropriate Inquiries page explains the federal framework.

Which physical items most often become price adjustments?

Roof age and warranty status, pavement and truck court condition, dock equipment, office HVAC, and electrical capacity. For storage users, fire protection is the one that surprises people: a sprinkler system adequate for the current tenant’s commodities and rack heights may not be adequate for the next tenant’s, and upgrades are expensive.

A property condition assessment turns these into a capital plan with timing, which is what you negotiate from.

If the building is already operating, how much does zoning conformity matter?

A lot, if you ever want to change the use, expand, add outdoor storage, or re-lease to a different kind of tenant. A legal nonconforming use can continue but may not be enlarged or re-established after a lapse. Get the zoning designation and a written answer from the municipality about the uses you actually plan.

What should I know about flood and stormwater for Chicago-area industrial sites?

Check the FEMA flood map first, then the local stormwater rules: in Cook County the Metropolitan Water Reclamation District administers a watershed management ordinance, and the collar counties and municipalities have their own requirements. Detention obligations can affect expansion plans and yard surfacing, and a flat, paved industrial site is not immune to drainage problems.

Illinois taxes and incentives

Will my purchase trigger a reassessment, and how do I underwrite it?

In Illinois a recorded sale is evidence an assessor can use, and reassessment cycles differ: Cook County reassesses by region on a triennial cycle; the collar counties revalue on their own cycles with annual equalization. Underwrite the bill you are likely to pay after the sale, not the seller’s current bill, and confirm the leases let you recover increases.

Build an appeal calendar during diligence. The property tax guide explains the process and links all nine county assessment offices.

Does a Cook County Class 6b incentive stay with the property when it sells?

Do not assume it. Confirm with the Cook County Assessor’s current incentive bulletins how much of the reduced-assessment schedule remains, what a change in ownership or occupancy requires, whether renewal needs a new municipal resolution, and what conditions could end it. Underwrite the deal with and without the incentive, and treat the difference as negotiable risk.

How does a TIF district affect an industrial owner?

You pay taxes normally; the district redirects the increment above a base to fund public purposes, often under redevelopment agreements. The practical questions are whether any agreement binds the property, when the district expires, and whether incentives you are counting on depend on it. Read the governing documents rather than the map legend.

Debt and capital

How do lenders size loans on small industrial buildings, and what trips borrowers up?

Lenders generally test loan-to-value, debt service coverage, and often debt yield, using their own definitions of income and expenses. What trips borrowers up is lease term shorter than loan term (expect rollover reserves or structure), environmental findings, appraisal gaps, recourse requirements, and prepayment terms that limit a later sale or refinance.

Confirm definitions early and model the lender’s case, not just yours. The debt-service calculator shows the arithmetic.

How should I think about refinancing risk at loan maturity?

Assume the refinance happens at a higher rate, a lower loan amount, and a tougher appraisal than today, and see whether the property still carries itself. Moderate leverage, staggered maturities across a portfolio, extension options, and a capital plan that does not depend on cash-out proceeds are the usual defenses.

When does SBA 504 financing matter to an investor?

It matters because owner-users compete for the same buildings. A company planning to occupy most of a building can often finance it through the SBA 504 program with a long-term fixed-rate component, which lets it pay a price an investor cannot justify on rent alone. Expect that competition on vacant or soon-to-be-vacant buildings, and expect it to disappear on buildings with long leases in place.

Timing, exit, and sourcing

How do I decide between selling, refinancing, and holding?

Start with capital: upcoming rollover, roof or pavement spending, loan maturity, tax basis and any exchange plan, and your own liquidity. Then ask whether you would buy the building today at the price you could sell it for. If the answer is no, the market is telling you something about the hold.

The selling guide covers what buyers will ask for and how a sale actually runs.

Who is the likely buyer of my building at exit?

For 10,000–100,000 SF industrial, usually some mix of owner-users, private investors, exchange buyers, and smaller funds—and the building’s size, condition, and lease profile decides which. A vacant functional building draws owner-users; a leased one with term draws investors and exchange buyers. Prepare the document file for the buyer you expect.

How are off-market deals really sourced?

Through relationships and persistence: direct outreach to owners, broker networks, estates and partnerships in transition, and lease expirations that make an owner rethink. Be fundable and fast when one arrives, and remember that “off-market” can mean mispriced in either direction—underwrite it like any other deal.
