Due Diligence for Commercial
In commercial real estate, the best investors aren't the sharpest negotiators, they're the best detectives. The deal is won or lost before you ever sign, in the unglamorous work of confirming that what's on paper actually matches reality, legally, financially, and physically. That's due diligence, and in Michigan it's where the real money is either discovered or quietly protected. Here's how to do it right.
Start With Zoning, Always
Before anything else, confirm the property's zoning classification with the city or township, because zoning decides what you're actually allowed to do with the building. Michigan's common commercial categories run from C-1 (neighborhood business) and C-2 (general commercial) to C-4 (highway or regional), plus I-1 and I-2 for industrial and MU for mixed-use or redevelopment overlays. While you're at it, read the municipality's Master Plan, it tells you the community's future land-use intentions, which can quietly make or break your value and your redevelopment options down the road.
Environmental: The Expensive Surprise
Michigan's environmental rules are strict under the Natural Resources and Environmental Protection Act (NREPA), and on commercial property you order a Phase I Environmental Site Assessment to identify any history of contamination or risk. If the Phase I flags something, a Phase II adds actual soil and groundwater testing. Here's the part most people miss: if contamination does turn up, it isn't automatically a dealbreaker, you may qualify for Michigan's Brownfield Redevelopment Credits or EGLE cleanup grants to offset the cost. A problem with a funding source attached is a very different problem.
Title, Survey, and the Easement Nobody Mentioned
Confirm legal ownership and exact boundaries through a title commitment that surfaces easements (utility, access, drainage), encroachments, and any recorded restrictions or agreements. This is not a box to check lightly, a Muskegon warehouse expansion got delayed six months when a survey turned up an unrecorded storm drain easement running right through the build site. The cost of finding that before closing is a survey fee; the cost of finding it after is your timeline.
Read Every Tenant File
If you're buying income-producing property, you inspect every tenant file, current lease terms and options, rent schedules, payment history, security deposits held, and any pending disputes or maintenance issues. Then do the one thing sellers hope you won't: compare the rent roll against actual deposits to confirm the cash flow is real. Don't treat the seller's spreadsheet as gospel, treat it as a claim to verify.
Inspect the Bones
Bring in qualified inspectors and engineers to review the roof and foundation, the electrical and HVAC systems, fire suppression and safety compliance, and ADA accessibility. Keep in mind that commercial buildings over 5,000 square feet often require separate mechanical and electrical inspections under the Michigan Building Code, so budget for that rather than getting surprised by it.
The Numbers and the Legal Fine Print
Ask for the last three years of operating statements, the utility and maintenance contracts, the property tax history and assessments, any existing insurance claims, and any pending litigation or code violations. Pay special attention to the tax projection, because reassessment after a sale can raise your expenses meaningfully, especially in commercial zones, and a pro forma built on the seller's old tax bill is a pro forma built on sand.
At closing, your attorney and REALTOR® make sure the entity and ownership documents are correct, the leases are properly assigned, your environmental and zoning contingencies are satisfied, and the title policy actually covers commercial use. One Michigan-specific item worth a final check: under the Commercial Real Estate Broker Lien Act (PA 195 of 2010), brokers can file liens for unpaid commissions, so confirm any are cleared before you close.
The Bottom Line
Due diligence isn't about hunting for reasons not to buy, it's about buying with total confidence. Whether it's a strip mall, a warehouse, or a redevelopment parcel, the thorough investigation you do up front is exactly what protects your bottom line later.
