I got curious about what people who own duplexes in St. Paul have actually made, and I don't mean what Zillow says the market did, I mean what the same building sold for the second time around.
So I went back to 2012 and pulled every 2-4 unit building in the city that sold and then sold again. There were 828 of them.
The middle one was bought at $199,900 and sold at $300,000 about four and a half years later, which works out to a gain of $90,375. Almost all of them made money, 96.6% in fact, and the 26 that didn't includes everybody who had to sell in 2023 when rates blew up.
Here's the part I wasn't expecting. The East Side beat Mac-Groveland, and not by a little. Duplexes in Payne-Phalen returned 9.2% a year while Mac-Groveland and Summit Hill returned 5.1%. When you rank the neighborhoods by return, the list comes out almost exactly backwards from what the neighborhoods cost.
Now to be fair, Mac-Groveland owners made more actual dollars, $103,500 against $71,300, because those buildings cost more than twice as much to buy in the first place. So if you've got the money and you want the bigger check at the end, that's a real argument. But if you're trying to get the most out of a smaller down payment, the data says go east.
The other thing that jumped out at me is that the year you bought mattered more than anything else you could have done. People who bought in 2015 made 10.1% a year, people who bought in 2021 made 4.7%, and people who bought in 2022 made 2.4%. These are the same buildings in the same neighborhoods, and the only real difference is that the typical purchase price went from $150,000 to $345,000.
Two things I should be upfront about. A building has to sell twice to show up in this at all, so anybody who bought well and is still happily holding isn't counted. And a few of the biggest winners did major renovations, which is construction, not the market.
If you own a duplex here or you've been thinking about buying one, message me and I'll send you the neighborhood breakdown.
