A Chicago buyer scrolling listings for a two-bedroom unit at the Harbours on North Beach will eventually pull up a market snapshot for South Haven's 49090 zip code. The number that comes back looks calm: a median price, a modest year-over-year shift, the kind of figure that invites a quick mental comparison to whatever they've seen in Union Pier or St. Joseph. It feels like solid ground to negotiate from.
It isn't, at least not for a condo. South Haven's housing market is really two markets wearing one number, and only one of them moves the way a median is supposed to move.
The Number That Looks Calm
Single-family homes in South Haven's 49090 zip code trade often enough that their pricing tells a real story. The Southwestern Michigan Association of Realtors, which publishes monthly sales reports for the zip code, tracked single-family sales rising 42 percent year over year in October 2025, 27 closings against 19 in October 2024, with the median selling price climbing 28 percent to $653,156 from $510,306 a year earlier. Coming into 2026, that trend held. By April 2026, SWMAR's report noted fewer single-family sales for the month but prices that kept rising anyway, a pattern consistent with a market where demand still outpaces what's available.
That's a market with enough transactions behind it to trust the average. Condos are a different story entirely, and the same reports make that obvious once you line up a few months side by side.
Two Clocks, Same Zip Code
In July 2025, SWMAR recorded two condo sales in the 49090 zip code, the same count as July 2024, yet the average price fell 35 percent year over year. Two months later, September's report showed condo sales down from the year before, but average condo prices up by double digits. By October, there were no condo sales at all, compared to a single unit that closed for $1.2 million in October 2024. January 2026 brought sharp declines in both single-family and condo activity, with median prices holding steady mostly because there was so little movement to disturb them.
| Month | Single-Family Sales | Single-Family Median | Condo Sales | Condo Price Change |
|---|---|---|---|---|
| July 2025 | Down YoY | Average dipped | 2 (flat YoY) | -35% YoY |
| September 2025 | Up YoY | Average up double digits | Down YoY | Average up double digits |
| October 2025 | 27 (+42% YoY) | $653,156 (+28% YoY) | 0 (vs. 1 in Oct. 2024) | No sales to compare |
| January 2026 | Fell sharply | Held steady | Fell sharply | Held steady |
| April 2026 | Fewer YoY | Continued rising | Not reported | Not reported |
Read that condo column again. A 35 percent drop, then a double-digit gain, then zero transactions, all within about six months. That isn't a market cooling or heating. It's a market so thin that whichever two or three units happen to close in a given month set the number, and next month a different two or three units will set a completely different one.
A median built on two sales isn't measuring the market. It's measuring which two sellers happened to close that month.
Why the Condo Side Stays This Thin
South Haven's condo inventory sits mostly in a handful of buildings along North Beach and near downtown, places like the Harbours, where units were bought as second homes or short-term rental properties rather than starter homes meant to turn over every few years. Owners who bought to keep a place on Lake Michigan for their own summers, or to run it as a rental during the season, have less reason to list opportunistically. When one or two units do come up, they often carry unusual features, an association budget with recent assessments, a top-floor view, a slip that's included or isn't, that make a single sale a poor stand-in for the building next door, let alone the whole zip code.
Single-family homes don't have that problem in the same way. There are simply more of them changing hands each month, enough that outliers get absorbed into the average instead of defining it.
What This Means If You're Comparing South Haven to Somewhere Else
If you're a buyer trying to decide between South Haven and another Harbor Country or Southwest Michigan town, the condo median you find on a portal is close to useless as a comparison point. The single-family median is a much more honest number, because it's built from enough transactions to represent an actual trend rather than a coincidence of timing.
Before you treat any South Haven condo price as a benchmark, it's worth asking a few questions that the citywide number can't answer:
- How many units in this specific building have sold in the past twelve months, not the zip code as a whole?
- Is the comp you're looking at from the same floor, view, and square footage, or just the same building?
- What's the association's current budget, and has there been a recent or upcoming special assessment?
- Does the unit currently generate short-term rental income, and if so, does that history transfer with the sale or end at closing?
- How many days did comparable units actually sit before selling, not the days-on-market figure for the whole zip code?
None of these questions show up in a median. All of them show up in the closing paperwork.
The Single-Family Side Is the Cleaner Read
If you're weighing South Haven against another lakeshore town on price alone, lean on the single-family data, not the condo data. The single-family trend, sales up sharply in the fall of 2025, prices continuing to climb into spring 2026 even as the number of sales slowed, describes a market with real, if uneven, demand behind it. That's a number you can plan around.
The condo trend describes something else: a market where the "price" changes depending on which two owners decided to sell that month. That's not a flaw in South Haven's market. It's simply what a thin, second-home-heavy segment looks like when you measure it the way portals measure everything else.
A Few Questions Worth Asking Before You Compare
Is South Haven's condo market actually weaker than its single-family market? Not necessarily weaker, just smaller and less frequently traded. A 35 percent swing in one direction and a double-digit swing in the other within the same year isn't a sign of weakness. It's a sign that too few transactions are doing too much work in the average.
Does this pattern show up in other Southwest Michigan lakeshore towns? Any town where condo inventory is concentrated in a handful of buildings, mostly owned as second homes, will show similar volatility once you separate the numbers by property type instead of looking at a blended median. South Haven's SWMAR reports happen to break the data out clearly enough to see it.
How should I actually value a condo here if the median isn't reliable? Ask for sales from the same building over the past year, not the zip code. If the building hasn't traded recently, look at comparable buildings with similar amenities, association dues, and beach proximity, and treat the citywide condo median as background noise rather than a benchmark.
South Haven rewards buyers who read past the first number. The single-family market will tell you where prices are actually heading. The condo market will tell you something different: that in a beach town built on second homes, a handful of closings can make the same zip code look like it's booming and slumping in the same season, and the only way to tell which is true for the unit you want is to look at it building by building.
If you're comparing South Haven to another Southwest Michigan lakeshore town, or trying to make sense of a specific condo listing against numbers that don't quite add up, Jackson Matson has spent more than two decades reading this market one building and one closing at a time. Let's Connect.
