Is the Suburban Multifamily Boom Cooling? August 2026 Twin Cities Duplex Report

The Twin Cities suburbs seem to have been the duplex, triplex and fourplex market’s golden child the last few years. No matter what challenges or hurdles the cities of Minneapolis or St Paul faced, the suburbs kept chugging along.

There are signs the may be changing.

In August, the seven-county area saw a 6-month supply of inventory. In other words, if no new properties came on the market from today forward, it would take that long to be sold out of inventory. This is the second highest in over a decade, with the last incident happening in February 2026, when there was a 7-month supply. This was also double July 2025’s  3-month supply.

This high mark was fueled by 37 new and 83 active listings. The latter represented a 13.7% increase over July, and a 31.7% year-over-year inventory spike.

The value-add opportunity of the month was found in South St Paul, where a 4 bedroom, 2 bathroom house conversion in need of updates listed at $175,000. A turnkey 7 bedroom, 4 bathroom Shorewood duplex topped the market at $685,000.  South St Paul lead the way in the number of new listings with 6. St Louis Park finished a distant second with 3.

Just 14 suburban multifamily properties sold in August. This represents a 26.3% decline from July, as well as August one year ago. The good news, however, is those who solud successfully netted a final sales price that was 100% of their orignal asking price.

These sellers spent am average of 26 and median of 19 days on the market.

South St Paul lead the way in August’s tally of sold properties as well, with 5. In fact, it was the only suburb to have post more than one transaction.  A 4 bedroom, 2 bathroom side-by-side Edina duplex topped August sales at $560,000. A 6-bedroom, 3 bathroom house conversion in South St Paul offered a chance at meaningful cash flow, selling for $230,000.

All-in, the suburbs posted an August average sales price of $291,108 and median of $379,450. Both represented declines from the month and year before. However, with just 14 transactions, it is difficult to conclude this represents falling values. That’s a number best determined by a longer view before drawing conclusions.

As interest rates rise and we get deeper into fall, buyers may continue to have plenty of properties to choose from.
