1580 Dallas St
Historic Victorian landmark with built-in income potential: two fully independent homes on one lot in one of Denver metro's most walkable pockets (Walk Score 91). The Marshall Cowing House, a designated Aurora historical landmark, pairs a 3-bed, 3-bath main residence (1,792 sqft) with period millwork, high ceilings, and floor-to-ceiling windows, with a completely separate 2-bed, 1-bath detached carriage house/guest house functioning as an accessory dwelling unit (ADU) with its own private entrance, kitchen, yard, and utilities. Both units now vacant and ideal for house hacking, investors, multigenerational living, an in-law suite setup, or owner-occupant with rental income. Market rental comps position the main house at $2,650–$2,700/month and the carriage house at $1,675/month, for combined income potential near $52,000/year against a $525,000 list price. Two independent income streams, zero shared systems. Recently updated with major system investments: new furnace servicing, new central AC (main), updated kitchens and baths, new fencing, radon mitigation, brick and mortar repair, and fresh paint throughout. Systems are current and well cared for. Both units feature separate utilities and meters; each operates as a completely standalone residence. Minutes to Stanley Marketplace, Anschutz Medical Campus, Aurora City Park, and Colfax dining. Two homes, one lot, real flexibility, immediate income potential.
