Rare equestrian estate opportunity in scenic Brookline, NH. This unique property offers substantial horse infrastructure and a flexible multi-unit residence at a value well below replacement cost. The main home features 4 bedrooms, 1 full bath and 1 half bath, generous living spaces, and a warm country-style layout. A private 1-bedroom in-law apartment with full bath and kitchenette provides ideal accommodations for multigenerational living, guests, caretaker housing, or rental potential. An additional office/studio space overlooks the barn and indoor arena, creating a one-of-a-kind work-from-home environment. Equestrian facilities include multiple barns, extensive stall space, an indoor riding arena, wash stall, tack and feed rooms, and large hay storage areas. The scale and layout of these improvements would be extremely costly to replicate today. The property has experienced deferred exterior maintenance and equestrian facilities require restoration and capital improvements. Major value is in the acreage, infrastructure, and irreplaceable barn and arena improvements. The home itself is fully livable as-is but reflects older finishes and systems. The property is offered below the current town assessment of $739,600, reflecting deferred exterior maintenance and restoration needs to the equestrian facilities. Replacement cost of the barns and indoor arena today would be substantially higher than the asking price alone, making this a rare opportunity to acquire irreplaceable equestrian infrastructure at a significant discount to reproduction cost. Priced accordingly and being sold as-is. Ideal for horse professionals, contractors, hobby farmers, or vision buyers seeking a value-add equestrian estate. Exceptional potential!
