There are three outbuildings that could be used as additional living space in the backyard, two of them are already done and ready to move in. They could likely be rented for $650 and $550. Both are one bedroom, with kitchen and living area and bathroom. If a person rents the 2 buildings out back, you’d have to offer water, gas and possibly free WIFI to both units. Gas water heater is shared. They are on a separate septic system.
Unit one (the blue house), stove and refrigerator included. Monthly electric is 100.
Unit two (the yellow house), stove and refrigerator included, monthly electric is 60.
Unit three (the green house) is currently used as storage.
