DSCR loans in Michigan: underwrite the tax bill you'll get, not the one you see

Michigan's opportunity — and its two hidden tax levers

On the surface Michigan looks like classic Midwest DSCR territory: affordable entry prices, real rents, big renter pools in Detroit and Grand Rapids. And it is — but Michigan property taxes don't behave like other states', and the difference lands squarely on investors. A DSCR loan qualifies on rent ÷ PITIA (the basics are in our DSCR loan guide), and in Michigan the "T" in PITIA is a moving target that jumps twice at closing: once because of uncapping, and again because of the non-homestead school levy. Underwriters who know Michigan model both. Sellers' listing sheets model neither.

Lever one: Proposal A uncapping — the tax bill resets when you buy

Since 1994's Proposal A, Michigan taxes are calculated on taxable value, which can only grow by inflation (capped at 5%) each year the owner holds the property — regardless of what the market does. But when the property transfers, taxable value uncaps and resets to the state equalized value (SEV), which is roughly 50% of market value. A longtime owner's taxable value might be a fraction of SEV; yours starts at full SEV the year after you close.

So the tax history on the listing is close to meaningless. The seller who bought in 2009 may be paying on a $70,000 taxable value while the SEV is $140,000. Your bill will be computed on $140,000. That alone can double the taxes — before the second lever even kicks in.

Lever two: losing the PRE costs you ~18 mills

Michigan owner-occupants claim a Principal Residence Exemption (PRE), which exempts them from up to 18 mills of local school operating tax. Rentals don't qualify. Buy a former owner-occupied home as an investment and you pay the full non-homestead millage — roughly 18 mills (1.8% of taxable value) on top of the base millage. This is one of the largest homestead/rental tax gaps in the country, and it's uniquely easy to miss because it never appears on the seller's bill.

Worked example: a Grand Rapids duplex, both levers pulled

You buy a duplex in Grand Rapids for $280,000. The seller, an owner-occupant since 2012, pays about $2,240/yr — taxable value $70,000 at a ~32-mill homestead rate. Here's your bill:

• Uncapping: taxable value resets to SEV ≈ $140,000 (half of the $280,000 price).
• Non-homestead millage: ~32 mills + ~18 mills = ~50 mills.
• Your taxes: $140,000 × 50 ÷ 1,000 = $7,000/yr, or $583/month — more than triple the seller's bill.

Now the DSCR. With 20% down your loan is $224,000; suppose quoted principal-and-interest is $1,515/month. Insurance on a Michigan duplex runs about $150/month. PITIA = $1,515 + $583 + $150 = $2,248. Combined rents of $2,900 give a DSCR of $2,900 ÷ $2,248 = 1.29 — a solid deal. But had you underwritten the seller's $187/month tax bill, you'd have believed the DSCR was 1.56 and possibly overpaid accordingly. Same house, two very different spreadsheets; only one closes at the price you modeled.

Detroit: real rebirth, real appraisal problem

Detroit's recovery is genuine — population stabilizing, neighborhoods like Bagley, East English Village, and Jefferson-Chalmers seeing sustained rehab activity, and gross rent yields among the highest in the country. The DSCR obstacles are practical:

• Condition. Much of the stock is pre-1940 and appraisers flag deferred maintenance. DSCR lenders generally require average-or-better condition (C4 or better); a C5 roof or dead furnace kills the file. Distressed buys usually need a bridge or fix-and-flip loan first, then a refinance into DSCR once stabilized.
• Comps. Block-by-block value swings make appraisals volatile; build appraisal-gap room into offers.
• Loan minimums. Plenty of Detroit houses trade below $100,000, under most DSCR lenders' $100,000–$150,000 floors.
• Land contracts. Seller financing by land contract is unusually common in Detroit. If you're buying out of one or refinancing one, expect title-seasoning questions and make sure the contract was recorded — unrecorded contracts create documentation headaches at refinance.

Grand Rapids: the stable star

If Detroit is the high-beta play, Grand Rapids is Michigan's compounder: a diversified economy (health care, manufacturing, furniture), consistent population growth, low vacancy, and a chronically undersupplied rental market. Duplexes and small multifamily in the $250,000–$400,000 range typically appraise cleanly and rent quickly. DSCRs there are usually won or lost on the tax modeling above, not on rent risk. Suburbs like Wyoming and Kentwood pencil similarly.

Winter and the rest of the carrying-cost stack

Michigan carrying costs don't end at taxes. Budget for winter: vacant-unit freeze risk (insurers may require maintained heat or winterization), snow removal on multifamily (often the owner's legal responsibility), and higher utility exposure where owner-paid heat is customary in older multifamily. Michigan also charges a transfer tax of roughly 0.86% of the sale price ($7.50 state + typically $1.10 county per $500), usually paid by the seller by custom but negotiable — relevant if you're the seller side of a BRRRR exit. On the plus side, Michigan's landlord-tenant regime is middle-of-the-road: no statewide rent control, deposits capped at 1.5 months' rent, and nonpayment evictions that typically move in 4–8 weeks.

The Michigan underwriting checklist

Model those four honestly and Michigan is a strong DSCR state — Grand Rapids for stability, Detroit for yield with a rehab plan. Model them off the listing sheet and you'll buy a 1.5 DSCR that's really a 1.2.
