Three parties produce a dollar figure for this house, for three different purposes, so they do not agree and were never meant to. The gaps are worked out here rather than left for you to hold in your head.

None of these is an appraisal. Your lender orders one of those once an offer is accepted, and it is the figure that decides how much they will actually lend.
Positioned on a high-visibility corner in the heart of downtown Ottawa, this fully vacant duplex offers a rare & flexible opportunity in one of the city's most connected, walkable & rapidly evolving neighbourhoods. Featuring two 2-bed units, along with four on-site parking spaces, the property provides immediate options for investors, developers, or owner-occupiers, with strong potential for redevelopment. Set on a northwest-facing corner lot the property benefits from Traditional Mainstreet zoning [TM14 H(17)], allowing for a variety of residential or mixed-use possibilities. This zoning supports everything from low- to mid-rise residential & boutique multi-unit projects to commercial space with residential above, making it well suited for thoughtful growth in line with the City's long-term vision. Full municipal services are already in place, offering a smooth path for both current use & future plans. A rare advantage in this urban setting is the four owned off-street parking spaces with access from Lyon Street, adding everyday convenience & long-term value. The corner lot layout also allows for flexible, efficient building design & strong street presence. The location truly sets this property apart. With Walk Scores in the mid to high 90s, everyday amenities such as groceries, cafés, restaurants, parks, boutiques & essential services are just steps away. The property is well served by multiple OC Transpo routes & is moments from Lyon LRT Station, providing quick access to downtown, major employment centres & the wider city. Surrounded by ongoing & future development, this central location continues to benefit from strong demand & long-term growth. Whether you're looking for a duplex with immediate potential, a smart land holding, or a prime infill opportunity, this is a compelling chance to secure a highly visible corner property in Ottawa's urban core.
