Union County real estate Market Report.
Information and statistics on the latest trends in the Union County real estate market, updated for May 2026. *
Union County is seeing a modest level of options for shoppers, with 46 homes on the market and 27 new listings in March 2026. Inventory has risen about 12 percent from the prior month, yet it is still down roughly 26 percent from a year ago. Buyers are acting on what is available, with 18 pending sales and activity up more than 38 percent year over year.
Pricing is adjusting as this activity plays out. The typical home value stands near $374,000, which is about 11 percent higher than a year ago but projected to cool to around $334,000 next month. Sellers are asking a median list price of about $440,000 now, with projections pointing closer to $403,750 in April 2026.
Homes are taking some time to move, sitting a median of 74 days on the market, slightly longer than both last month and last year. Only about 18 percent of properties are selling above list price, and roughly 15 percent of listings see a price cut, while the average sale is closing at about 97 percent of asking. With just 2.7 months of supply and a seller’s market gauge of 26, conditions still lean toward sellers even as pricing softens relative to demand. Agent Pronto can connect both buyers and sellers with a local Union County agent who understands these trends and can guide them through the next move.

Union County offers residents a welcoming community, excellent schools, abundant outdoor recreation, and a growing economy that supports families and local businesses.
Union County stands out from nearby Sioux City and Dakota Dunes with a quieter rural pace that still keeps you close to major employers, shopping, and cultural events. Many residents choose communities like Beresford, Alcester, and North Sioux City for their strong local identity, where schools, sports, and civic events bring people together throughout the year.
Along the Missouri and Big Sioux rivers, outdoor time is part of daily life. Families gather at Adams Homestead and Nature Preserve for walking and biking trails, birding, and river views, while golf and community events are a draw at Two Rivers Golf Club. Local history and culture are highlighted through county resources and nearby museums, including the Union County Courthouse in Elk Point and regional institutions like the Sioux City Public Museum.
Strong schools are a key reason families stay, with districts such as Dakota Valley School District and Alcester-Hudson School District offering close-knit learning environments and active extracurricular programs.
Whether you already live in Union County or are relocating for work or lifestyle, planning your move is crucial.

“Vanessa was the most amazing realtor I could have ever asked for! As a first-time homebuyer, she made sure we had a meeting before we even started viewing properties, so I knew exactly what the whole process entailed. She made me feel incredibly comfortable and ensured I understood every step along the way. She is an extremely patient, caring person, and I cannot recommend her enough! She went above and beyond, bringing delicious Bundt cakes and a cute card on closing day to celebrate. She truly treated me like family. Thank you again, Vanessa, and the whole Hirschi Realtor Group—you guys are awesome!”

She shared her insights on each property without trying to talk us into or out of any of them... and once we found the cabin we were ready to purchase, Katelyn made the process seamless. We highly recommend Katelyn and really enjoyed working with her throughout the process.”

“Allison went above and beyond for us with the sale of our home and the purchase of a new one. She's very knowledgeable. Like I said, there we so many tasks and things that I feel were outside of her responsibility/ duties as a realtor, but she took over and helped us with it anyways. I thought many of the calls and meetings she came to were very helpful & thoughtful. Like I said she has a "go Above and beyond" mentality of a realtor. I also appreciate her being very avaliable & easy to reach. I never had any issues contacting her , waiting on responses etc. If we do need another realtor I'd only want to work with her. She's also very knowledgeable with all aspects of reality (our new build home and our older model double wide). Even during any downtime she'd give us tips and tricks to take care of our new home & market our old home to sell FAST. It was under contract in less than a week and after only three showings.”

“Dan was absolutely fantastic. He was always very responsive and whenever we wanted to see a property he would get us in same day sometimes within hours of the request. Dan's knowledge of all the areas we looked in was exponential and he was fantastic at negotiating and fighting for us to get all of the essentials we needed for our family. I would recommend Dan and Camille to anyone looking to purchase a property in the near or far future”

“Where to begin with Elise... she handled our first purchase of our home two years ago, and exceed our expectations then. With a family now, we needed an upgrade and we honestly could never have expected a better experience than the first time. Yet here we are. Elise has helped us not only sell our first home, but purchase our forever home. There were so many curveballs on both sides of this and Elise handled each and every one with grace, determination, and accommodation. There were moments it felt like we weren't going to be able to move forward with the sale/purchase, but Elise fought tooth and nail and made it happen. Working with Elise felt like we were more than just a transaction. Every step of the way we were updated and each step was explained in detail so there was no guessing "what comes next". We would work with Elise a million times over if we could! Hands down the best realtor out there, no question about it!”

“I highly recommend Tracy Burgess as a real estate agent. She is insightful, knowledgeable, and very experienced. She has a great network of contractors who work with her and help to make things run efficiently. Tracy listens well and is very supportive during a time that can be stressful. She did a great job staging the house and was really good at communicating with us. Bottom line ... she's a dynamic real estate agent !”

His dedication, communication, and genuine care truly made a difference, and I would highly recommend him to anyone looking for a reliable and hardworking realtor.”

“This was our nightmare house. So thankful for Shellyn's Sands efforts to save the deal that could have gone sideways. Mission Accomplished. If you get to work with Shellyn, you will have wealth of experience and knowledge wrapped up in a cheerful, energetic, package. But that's not all. Shellyn either answers or texts back right away. That's huge. I don't know about you, but I hate waiting. Well Done, Shellyn”
