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.
History meets limitless potential. Steeped in a local heritage, this striking 4545 square foot industrial masterpiece offers a rare opportunity to own a piece of architectural history. Originally built in 1905 as the renowned "Westinghouse Factory Historic Site," this iconic building - now affectionately known as the "Charcoal House" - is ready for its next grand chapter. Constructed with the enduring craftsmanship of a bygone era, the building has a robust, industrial backbone designed to withstand the test of time. Cast-in-place reinforced concrete. Solid concrete columns, heavy duty beams, and a durable concrete roof deck. Classic masonry infill walls that ooze raw, urban character. Whether you are looking to expand your business or invest in a growing community, Charcoal House is a blank canvas awaiting your vision. Create an inspiring loft style tech hub or creative agency. Stand out with a unique, chic storefront, or create an ultimate, reliable base of operations for plumbers, electricians, woodworkers or builders. Capitalize on the booming demand for secure, solid storage solutions. Structures with this level of historical character and structural integrity rarely reach the market. Don't miss your chance to redefine a piece of Donald's history. This property is not designated under the Ontario Heritage Act.
