Quick answer: Michigan hits an incoming investor with two tax changes at the same time, and almost every out-of-state spreadsheet models neither. Uncapping: in the year after a transfer of ownership, taxable value is uncapped to the property's state equalized value — roughly half of estimated market value. Loss of the Principal Residence Exemption: the seller's exemption from 18 mills of school operating tax does not transfer, and a rental cannot claim it. On a $100,000 taxable value those 18 mills alone are about $1,800 a year. Both land in PITIA, which is the denominator of your ratio.

Get My QuoteMichigan is the friendliest state on this list for clearing a DSCR ratio, and the easiest one to underwrite wrongly. Price-to-rent relationships here are genuinely favourable — properties pencil that would be hopeless in California. But the tax line moves twice the moment you buy, and an investor who models the seller's bill can turn a real margin into an imaginary one before the first tenant moves in.
Key takeaways
- Uncapping: annual growth in taxable value is capped while ownership is unchanged, and in the year following a transfer the taxable value is uncapped to state equalized value — roughly half of estimated market value.
- The Principal Residence Exemption does not transfer. It exempts a principal residence from 18 mills of local school operating tax, and a rental does not qualify.
- Scale: on a $100,000 taxable value, 18 mills is roughly $1,800 a year back onto the bill.
- The two effects compound. Uncapping raises the base; losing the exemption raises the rate applied to it.
- Do not claim the exemption on a rental. It requires owner occupancy.
- Municipal rental registration is real in several Michigan cities, Detroit among them, and can gate lawful renting.
- Favourable ratios are the upside. Michigan price points clear thresholds high-cost states cannot.
The double reset
Most states that trap investors on property tax do it one way. Texas has a homestead cap that does not transfer. California reassesses to purchase price. Michigan does both kinds of thing at once, through two independent mechanisms, and that is what makes it distinctive.
Mechanism one changes the base your tax is calculated on: taxable value uncaps on transfer. Mechanism two changes the rate applied to that base: the Principal Residence Exemption disappears, putting 18 mills of school operating tax back on. Because they compound, modelling only one of them still leaves you materially short.
Neither is visible in the seller's bill, which is precisely the document most investors use as their estimate.
Uncapping, specifically
Michigan limits how fast a property's taxable value may rise while ownership stays the same. That protection is attached to continuous ownership, not to the property. In the year following a transfer of ownership, the law requires taxable value to be uncapped, and it resets to the property's state equalized value — approximately half of estimated market value.
For a long-held property the gap between a capped taxable value and current state equalized value can be considerable. That gap is not a risk you are taking; it is an increase you are scheduled to receive. Ask the local assessor what the state equalized value is, and model from that rather than from the seller's taxable value.
Losing the Principal Residence Exemption
The Principal Residence Exemption exempts a principal residence from 18 mills of local school operating tax. Qualification requires the owner to both own and occupy the property as their principal residence. A rental does not qualify, and the exemption does not travel with the deed.
To put the scale in plain numbers: on a property with a taxable value of $100,000, 18 mills is in the region of $1,800 per year. That is roughly $150 a month landing inside PITIA — and on a Michigan rental where the whole monthly housing cost might be modest, $150 is not a rounding error against the ratio. It can be the difference between clearing a threshold and not.
Two practical notes. If you are converting your own former residence into a rental, talk to the local assessor about rescinding the exemption on the correct timeline. And do not claim it on an investment property; it is not available and the correction is unpleasant.
The upside, stated honestly: Michigan ratios clear
It would be a distortion to write about Michigan purely as a tax hazard, and it is the honest counterpoint to California. On the arithmetic that actually decides a DSCR file, Michigan is one of the more favourable states in the country. Price-to-rent relationships in much of the state, and in Detroit in particular, mean the numerator does more work relative to the denominator than it can in a high-cost coastal market.
The consequence is real: properties clear 1.25 here that would struggle to clear 1.00 in California. Investors priced out of ratio-based lending elsewhere frequently find Michigan is where the product works for them.
The corresponding discipline is that when the financing is easy to qualify, the property decisions carry the risk instead — condition, tenant quality, municipal compliance, and the tax reset described above. A strong ratio is not the same thing as a good investment, and the calculator deliberately says so.
Municipal rental registration
Several Michigan municipalities operate rental registration and inspection regimes, and Detroit in particular has requirements for rental property. These are local ordinances rather than state law, and they can carry registration, inspection and certification obligations that gate whether a property may lawfully be rented at all.
For an investor this is a diligence item with a timing consequence, not just a cost: a property you cannot lawfully rent yet is a property producing no income while the loan is outstanding. Confirm the requirements with the municipality before closing.
Getting the Michigan file right
- Get the state equalized value from the local assessor, not the seller's taxable value.
- Add back the 18 mills. Assume no Principal Residence Exemption, because you will not have one.
- Check municipal rental registration for the specific city, and the timeline to compliance.
- Quote insurance on the address, and confirm association dues where applicable.
- Then run the ratio — and if it still clears comfortably after all of that, you have a genuinely strong Michigan file.

DSCR loans in Michigan: FAQ
Why will my Michigan tax bill be so much higher than the seller's?
Because two separate things happen at once, and most investors only know about one of them. First, uncapping: Michigan caps annual growth in a property's taxable value while ownership is unchanged, and in the year following a transfer of ownership the taxable value is uncapped to the property's state equalized value — roughly half of estimated market value. Second, the exemption: the seller's Principal Residence Exemption does not come with the house. Together those two can move the bill substantially, and both land inside your PITIA.
What is the Principal Residence Exemption worth?
It exempts a principal residence from 18 mills of local school operating tax. To put a number on the scale: on a property with a taxable value of $100,000, 18 mills is about $1,800 a year. A rental does not qualify — the exemption requires the owner to both own and occupy the property as a principal residence. So an investor buying a homesteaded house should expect that amount to come back onto the bill.
Should I claim the Principal Residence Exemption on a rental?
No. It requires owner occupancy, and claiming it on a rental, a second home or investment property is not available to you. Beyond being wrong it is the kind of error that gets corrected with interest. If you are converting a former residence to a rental, speak with the local assessor about rescinding the exemption on the right timeline.
What are the DSCR loan requirements in Michigan?
Standard: non-owner-occupied, genuinely business-purpose, rent supporting full monthly housing cost, with credit, reserves and entity documentation. Common practice is around 20–25% down with three to six months of PITIA in reserves. Michigan changes the tax input inside the ratio, not the rulebook around it.
Do Michigan price points make the ratio easier?
Often, yes, and it is the honest counterpoint to California. In much of Michigan, and in Detroit in particular, price-to-rent relationships are far more favourable than in high-cost coastal markets, which means properties clear DSCR thresholds that would be impossible elsewhere. The trade is that condition, tenant quality, municipal compliance and the tax reset do more of the work in deciding whether the deal is actually good.
Are there local rental registration requirements?
In several Michigan municipalities, yes, and Detroit in particular operates a rental registration and compliance regime for rental property. These are local ordinances rather than state law, and they can carry inspection and certification obligations before a property may lawfully be rented. Confirm the requirements with the municipality the property sits in before you close, not after your first tenant.
Is there a transfer tax in Michigan?
Yes. Michigan imposes a state real estate transfer tax with an additional county-level tax, both assessed on the value conveyed. Your title company will give you the figures for the specific transaction. Note this is a charge on the conveyance, not on your note — unlike Georgia, which taxes the financing itself.
The bottom line
Michigan gives you favourable ratios and takes back some of the margin through a tax reset that happens twice. Model the uncapped state equalized value, assume the 18 mills are on your bill, confirm the municipality's rental requirements, and then judge the deal. Done in that order Michigan is one of the better states on this list for ratio-based lending. Done from the seller's tax bill, it is one of the more disappointing.
If you have an address in view, send us the property and the expected rent and a loan officer will run the ratio on the numbers that will actually apply to you. Before you commit to anyone, it is worth putting the six questions to every lender you are considering. Valley West Mortgage is a mortgage lender, NMLS #65506. Equal Housing Opportunity.
