The tools we build on top of the listing, each figure sourced and none of it PropTx data: what the house really costs to hold, what it costs to borrow against, and the inspection to book before your conditions come off.

The price, facts, description and history exactly as the feed states them. Nothing in this section is our own estimate.

What comes from PropTx, and what is ours
The price, address, room and size figures, description and days on site are sourced from PropTx and can lag the live listing. The map placement and the cost, offer, insurance and rental tools below are our own work, not PropTx data. Anything we have modelled rather than sourced carries an Est. tag.

THIS IS AN L SHAPED PROPERTY WITH FRONTAGES ON BOTH GEORGE ST AND KING ST. Approx dimensions : 144' ( across the back) X 132' (on George St) X 32' ( King St at George corner) X 70' (north of other dwelling) X 47' across back of other dwelling) X 70' X 19' X 70' (driveway on King) X 45'. PLEASE SEE DRAWING IN SUPPLEMENT. Currently used as a warehouse for an online business. The R4-CH zoning allows for residential so the possibilities are many for this +/- 16,893 sq ft concrete/concrete block building! The main floor offers +/- 10,584 sq ft with another +/- 6309 sq ft on the second floor. The property is irregular and wraps behind 2 residential units. A driveway on King St between the two units, provides access to another part of the building. The main floor has a one bedroom apartment and a large office space (+/- 400 sq ft) plus there are 3 loading doors with various heights and many other door entrances, so dividing this building into smaller units is doable! There is a large parcel of land behind the building that is owned by the Seaway and they are willing to sell that parcel at a reasonable price. This would be an a fantastic acquisition to the building and could provide the necessary parking if the buyer wanted to convert the existing building to full residential or add on.
Written by the listing brokerage to sell the house. Nothing in it is verified, so take its claims about condition to an inspection, not from it.

None of this is PropTx data. Each figure is our own and carries its source: the true cost to own, the mortgage studio, the inspection plan, and the rest.
At 20% or more there is no CMHC premium.
20% down · 4.65% indicative 5-yr fixed · The number of years the whole balance is paid off over. A longer amortization lowers the monthly payment and raises the total interest.. $9,700 for 2026, from the tax figure stated on the listing, divided by twelve. That is what the current owner pays, as the listing states it. That twelfth is the annual amount levelled across the year and not a payment you will make on any date. How a municipality actually collects it is set out in documents nobody here has read.; heat and utilities estimated. Figures illustrative.
Compare lenders and private optionsIt asks one question first: whether someone is already acting for you. That answer changes who books the visit and who is on your side inside the house.

The listing does not say whether there is a second dwelling unit here. Other records in this set state it either way, so this is a silence rather than a no.

Two figures stand against this house for two different purposes, the asking price and the assessment, so they do not agree and were never meant to. The gap is worked out here rather than left for you to hold in your head.
Nothing of this kind on the record, and nothing here fills it in from an average of other houses.
The figure property tax is apportioned from, valued as of a date that is not today. It is not a market value and no lender treats it as one.
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.
