Redevelop the parcels around me into apartment buildings and a village farm.
Build a road, construct new 5 units with flat roof and rooftop garden beds, replace three SFH with two new duplex's, install buried electric service, build a barn/tool share space, build a pavilion with camp sites and river access, build an outdoor pizza oven, fencing and housing for goats, chickens, and pigs, build a bridge over a wetland, plant maple trees, plant apple trees, build covered parking one car spot and two bike spots per unit with solar panels on top, heated garage space for vehicle maintenance, concrete bays for neighborhood and farm compost.
I figure the property purchases are in the 1 M range. There are 6 properties to buy with 10 existing units in two apartment buildings and 3 sfh. New construction for the buildings maybe I could keep it to 1.5 M. But probably a few hundred more would be needed.
