Multifamily investment covers everything from a duplex bought with a conventional mortgage to a two-hundred-unit community financed with commercial debt, and the gap between those two ends of the spectrum is wider than the shared label suggests. Unit count alone changes financing, management expectations, and how the property gets valued, so it's worth separating before comparing any two deals side by side.
Where Financing Draws the First Line
Properties with two to four units generally qualify for residential financing, including owner-occupant loan programs that require a much smaller down payment than a five-plus unit building would need. Cross that line into five units or more and financing shifts to commercial underwriting based on the property's net operating income rather than the borrower's personal income, which changes both the qualification process and how much leverage is realistically available.
Michigan's Rental Markets Don't Move Together
College towns like Ann Arbor and East Lansing run on an academic leasing calendar with near-total summer turnover, Detroit's suburban ring trades more like conventional workforce housing tied to auto-sector and manufacturing employment, and northern markets like Traverse City compete with vacation-rental demand for the same housing stock. An investor comparing a Kalamazoo building against a Sterling Heights building isn't just comparing price per unit, they're comparing two different tenant bases with different turnover risk.
Property Tax Uncapping Is a Michigan-Specific Wrinkle
Michigan resets a property's taxable value to the state equalized value whenever ownership changes hands, so the tax bill a seller has been paying often understates what a new owner will actually pay in year one. That reset can meaningfully change the return math on a building that hasn't traded in a decade or more, and it's easy to miss for an investor pulling comparables from a seller's own financial statements rather than the assessor's uncapped estimate.
Verifying What the Rent Roll Actually Shows
A rent roll reflects what's billed, not necessarily what's collected, so comparing it against bank deposits and a trailing operating statement is standard diligence before treating the reported income as reliable. Deferred maintenance also shows up more bluntly in Michigan's freeze-thaw climate than in milder states, which is why roof age, boiler condition, and parking lot heaving deserve attention alongside the financials rather than being left for after closing.
How a 1031 Exchange Applies to Multifamily
An investor selling an appreciated Michigan property, whether it's a single-family rental, land, or another multifamily building, can move the proceeds into a new apartment property through a 1031 exchange and defer the gain rather than paying tax on it at the time of sale. That deferral applies whether the replacement is a small building bought directly or a fractional DST interest in a larger community, since like-kind treatment covers investment real property broadly rather than requiring the same unit count or building type.
Common 1031 Exchange Questions
What's the real difference between a duplex and a five-unit building as an investment?
Beyond the extra unit, the financing changes entirely. A duplex through fourplex generally qualifies for residential loan programs, while five units and up require commercial underwriting based on the property's income, which typically means a larger down payment and a different qualification process.
Why does a college-town multifamily property behave differently than a suburban one?
College towns like Ann Arbor and East Lansing see near-total annual turnover tied to the academic calendar, while suburban properties tied to broader employment tend to have steadier, more staggered turnover throughout the year, which changes both leasing effort and vacancy risk.
Can I 1031 exchange a single-family rental into a multifamily property?
Yes, as long as both properties are held for investment or business use, the exchange rules treat real property broadly as like-kind, so moving from a single-family rental into a multifamily building doesn't disqualify the exchange.
How does Michigan's property tax uncapping affect a multifamily purchase?
Because taxable value resets to the state equalized value at transfer, a building that hasn't sold in many years can carry a meaningfully higher tax bill under new ownership than the seller's trailing statements show, which should be built into the return projection before closing.
Is a rent roll enough to evaluate a multifamily property's income?
Not on its own. A rent roll shows what's billed, not what's actually collected, so comparing it against bank deposits and the trailing operating statement gives a more accurate picture of the property's real income before an offer is finalized.
