About this home

Welcome to this rare opportunity to acquire substantial acreage in Washington County MN! This 86+/- acre parcel is in the ideal location to provide a wonderful, secluded retreat or potential for development opportunities. There seems to be many locations to build homes while maintaining a very private setting. The elevation changes throughout the ground make this parcel really stand out creating a unique canvas for a future home builder. There is a very diverse piece of land with mature timber throughout along with a well-maintained trail system that allows you to navigate the property with ease. If you are seeking a large acreage tract that is in very close proximity to the Metro Twin Cities area this parcel is approximately 30 minutes NE of Minneapolis / St. Paul, 18 minutes East of Forest Lake and 7 minutes North of Marine on St. Croix! Not only do you get to experience the quiet country lifestyle, but you are also right next door to all the amenities and near the St. Croix River that offers endless opportunities for recreation. This property comes equipped with a 2-bedroom 1- bathroom home that is tucked in and overlooking a pond! This natural water source will offer wildlife and waterfowl viewing at its finest. Heavily used game trails throughout. This property would offer outstanding hunting opportunities across the board. Whether you are a whitetail, turkey, or a bird hunter, this place will absolutely deliver a great experience. Parcels of this size and potential in this location are becoming increasingly harder to find in this vicinity and not very often do tracts like this come for sale. This is an all-around great opportunity whether you are looking for a private country retreat or a potential development opportunity. This is definitely worth the time to come check out! Schedule your private tour today!

How SODL buyer credits work

When you buy with SODL, the brokerage charges a flat $3,000 platform fee at closing. The remaining buyer-side commission (typically 3% of the purchase price) is credited directly back to you at closing, reducing the cash you bring to the table.

  • Tour homes with SODL’s flexible showing network
  • Submit offers and manage your transaction through the platform
  • Keep more money at closing through transparent flat-fee pricing

A clear, modern way to buy with expert guidance and meaningful savings.
