Charming Cottage-Style Home on a private cul-de-sac in a Prime Location
Beautifully updated 3-bedroom, 2.5-bath story-and-a-half home tucked away on a quiet cul-de-sac, just steps from Wapelhorst Park and with convenient access to Highways 364 and 70.

The basement adds incredible versatility with a unique indoor soccer field/play area, providing the perfect space for year-round recreation, sports, fitness, or family fun.
Additional highlights include gorgeous hardwood floors, main-floor laundry with powder room, a built-in mudroom cubby off the two-car garage, new roof, and new main-floor furnace.
