The Harbor Springs Property Tax Line That Belongs to Someone Else

A buyer looking at a Harbor Springs listing almost always asks about taxes at some point, and almost always gets pointed at a number already printed on the sheet. That number is real. It is also not theirs.

It belongs to the current owner, calculated on a taxable value that has been quietly capped and crawling upward for however many years that owner has held the property. The day a sale closes in Michigan, that link breaks. What the buyer actually inherits the following year is a different figure entirely, and the distance between the two is often the single largest cost nobody priced into the offer.

What the number on the sheet is actually measuring

Michigan runs on three separate values for the same house: assessed value, state equalized value, and taxable value. Only the last one determines the bill, and it almost never matches what the house is worth today. Under Proposal A, a property's taxable value can only climb by the lesser of inflation or 5 percent each year the ownership stays put, no matter how fast the local market moves. Emmet County's own guidance to property owners is blunt about what happens next: a property does not uncap to the selling price, it uncaps to the state equalized value the year after the transfer takes place, and that equalized value is set independently by the assessor using recent comparable sales, not by whatever number appears on the deed.

That distinction matters for a Harbor Springs buyer more than almost anywhere else in the region, because the whole point of the cap is to protect long-term owners, and the whole cost of it lands on whoever buys next.

A cap that's been loosening, and a gap that's been widening

The cap itself has not been static. Emmet County's records show the 2024 inflation figure landed at 5.01 percent, which meant taxable values for continuing owners were locked at the full 5 percent ceiling that year. For 2026, the Michigan State Tax Commission set the multiplier at just 1.027, a 2.7 percent increase, a meaningful step down from the run of 5 percent years just before it.

A slower cap sounds like relief. For anyone about to buy, it is closer to the opposite. The cap only limits how fast a taxable value can rise for someone who keeps the house. It does nothing to slow the state equalized value, which the county recalculates every cycle based on actual sales activity, using a rolling 24-month sales study as its methodology. Every year a longtime owner's bill creeps up at 2.7 percent while the house itself is worth meaningfully more, the gap between what they've been paying and what a buyer will pay the year after closing gets wider, not narrower. A gentler cap this year does not soften the landing for the next buyer. It stretches the runway leading into it.

Here's what that divergence looks like over time, using round numbers to illustrate the mechanism rather than any specific listing:

The owner in that left column is paying taxes as if the house barely appreciated. The buyer who takes over in year 10 starts fresh at the right column's number, in one step, the following tax year.

The exemption a second home never gets

Uncapping is a one-time event. There is a second, permanent gap that has nothing to do with a sale at all.

Michigan's Principal Residence Exemption shields an owner-occupied home from 18 mills of local school operating tax, but only if the property is actually lived in as the owner's primary residence and the affidavit is filed with the local assessor by June 1 or November 1. A home used seasonally, no matter how many decades a family has owned it, never qualifies. That means two houses that look identical from the street, one occupied year-round and one used as a second home, are already carrying structurally different tax bills before either one changes hands.

Picture two condos a block apart in the Bay Point association, purchased the same year for the same price. One buyer relocates full-time and files the exemption. The other keeps a primary residence elsewhere and uses the Harbor Springs unit as a second home. Long before either owner's capped value has a chance to catch up to the market, the second owner is already paying 18 more mills than the first, every single year, for as long as it stays a second home. That gap sits on top of whatever uncapping does at the moment of purchase. It does not fade with time. It is simply what the property is.

Same block, different bill

Put the two mechanisms together and the practical picture for a Harbor Springs buyer looks like this: a longtime local family selling the house they raised kids in, on Beach Drive or up near Birchwood Farms, has likely been paying taxes on a capped value that has drifted well below what the county now considers the home worth. An out-of-state buyer purchasing that same house as a second home walks into two changes at once. The taxable value resets to the current state equalized value in the first year of ownership, and the home never qualifies for the exemption the departing family may have held for decades. Neither change shows up anywhere on the listing sheet. Both show up on the first bill.

This is why the seller's current tax figure is close to useless as a forecasting tool for anyone buying a second home in Harbor Springs, and why relying on it is one of the more common ways a buyer's actual carrying cost surprises them well after closing.

How to price your own number before writing an offer

The fix is not complicated, it just has to happen before the offer goes in rather than after the first bill arrives.

Michigan's own Property Tax Estimator lets a buyer enter a parcel's state equalized value, not the seller's current taxable value, and select whether the property will be a primary residence or a second home, rental, or business. Running the second-home version of that estimate against the actual SEV, which the city assessor's office can confirm, gives a far more honest number than anything printed on a listing sheet. In Harbor Springs, that office is currently overseen by Assessor Jeff Grimm, and questions about a specific parcel's equalized value belong there, not with a generic online calculator.

One more piece of paperwork matters after closing. Michigan requires a Property Transfer Affidavit be filed with the local assessor following a sale, and failing to file it brings its own penalty on top of whatever the uncapped bill turns out to be. It is a small form with real consequences for skipping it, and it is exactly the kind of detail that gets lost in the excitement of closing week.

A few questions worth settling before closing

Will my tax bill be based on what I actually paid for the house? No. It uncaps to the state equalized value the year after the transfer, not the purchase price. The assessor sets that value independently using comparable sales, so it can land above or below whatever number is on the deed.

If I buy from a family member, does uncapping still apply? Certain transfers, mainly between spouses or under a narrow set of family exemptions, are excluded from uncapping. A standard purchase at fair market value, even from a relative, typically still triggers it. Anyone hoping a family sale will avoid the reset should confirm the specific transfer type with the assessor before closing, not after.

Can a Harbor Springs second home ever qualify for the Principal Residence Exemption? Only if it stops being a second home. The exemption requires the property to actually serve as the owner's primary residence, verified through the affidavit filed with the local assessor. Years of seasonal ownership, on their own, never qualify a property for it.

Pricing a Harbor Springs purchase well means running these numbers before the offer goes in, not reading them off the seller's current bill and hoping they carry forward.
