What Due Diligence Do I Need Before Buying Commercial Real Estate?
Due diligence on Rochester commercial real estate runs through a structured 45 to 60 day timeline that produces clear documentation on financial, physical, environmental, and legal aspects of the property. Each workstream has specific timing, deliverables, and decision points. Buyers who run diligence on a real timeline rather than scrambling near the deadline produce clean acquisitions and protect earnest money.
Week 1 sets up the framework. Engage the diligence team including the broker, commercial attorney, commercial inspector, environmental consultant, and lender. Send document request lists to the seller covering trailing 36 months of operating statements, current rent roll, all leases and amendments, utility bills, property tax bills, insurance loss runs, capital expenditure history, service contracts, and any environmental reports the seller has. Schedule property inspection and Phase I site visits. Begin reconstruction of NOI from initial documents the seller provides.
Weeks 1 through 3 cover financial verification. Review every lease and confirm terms match the rent roll. Send lease estoppels to each tenant for execution within 14 to 28 days. Reconstruct operating expenses including property management, capital reserves, and any items the seller may have understated. Calculate verified NOI using actual rents from leases and estoppels and verified operating expenses with post sale property tax estimates. Compare to OM numbers and identify discrepancies.
Weeks 1 through 3 also cover physical inspection. Commercial inspector walks the property systematically. Roof condition. HVAC age and condition. Plumbing and electrical. Foundation and structural elements. Parking lot. Site drainage. ADA compliance. Michigan freeze thaw cycles wear on parking lots and roofs faster than mild climates, so even newer buildings can have issues that affect capital planning. Inspector produces a written report identifying current condition and any items requiring repair or replacement in the next 5 years.
Weeks 1 through 4 cover environmental due diligence. Phase I environmental site assessment for industrial property and most older commercial property. Phase I costs $2,500 to $4,500 and takes 2 to 3 weeks. The environmental professional reviews historical records, regulatory databases, and visible site conditions. If Phase I identifies recognized environmental conditions, Phase II sampling may be needed at significantly higher cost and additional weeks of investigation. Michigan has specific Baseline Environmental Assessment regulations under Part 201 that affect how environmental risk gets allocated on contaminated properties.
Weeks 2 through 4 cover title and survey. Title company produces title commitment showing exceptions including easements, restrictive covenants, encroachments, and unrecorded leases the buyer will take subject to. ALTA survey from a licensed Michigan surveyor confirms boundaries, improvements, easements on the ground, and any encroachments. ALTA surveys cost $3,000 to $6,000 and take 21 to 35 days. Title exceptions and survey findings get reviewed for any that limit the intended use or create unacceptable risk.
Weeks 2 through 5 cover financing. Lender orders appraisal which takes 14 to 28 days. Underwriting reviews borrower and property financials. Loan committee approval comes after underwriting completes, with conditions that need to clear before closing. Buyers should engage their lender immediately at contract execution rather than waiting until later in diligence.
Weeks 3 through 5 cover zoning verification. The buyer confirms that intended use is permitted under current zoning or whether it requires conditional use approval or rezoning. Rochester, Rochester Hills, Troy, and surrounding municipalities each have different codes, so checking the specific jurisdiction is essential. A buyer planning to operate light manufacturing in a commercial zoned building needs to verify use permission before relying on the property.
Weeks 4 through 6 cover review and decision making. The buyer synthesizes findings from all workstreams. Items requiring remediation or credit get negotiated with the seller. Items the buyer can accept get noted but not pursued. If material issues emerge that the seller will not address, the buyer evaluates whether to terminate within contingency period and recover earnest money or to proceed with awareness of the issues. Michigan attorney close means legal counsel review happens on both sides throughout this process, which catches issues earlier than states without that structure.
Coordination among workstreams is the broker’s primary diligence role. Workstreams need to start on time, run in parallel where possible, and complete with enough margin to make informed decisions before the contingency deadline. Buyers who scramble at deadline make worse decisions than buyers who manage timeline actively.
