Buying half a duplex and buying a whole duplex in Edmonton are two different transactions that happen to share a building shape. A half-duplex is a home purchase with a shared wall, a shared roof line and usually a party-wall neighbour you did not choose. A whole duplex is a home plus an investment: two titles or one, two households, rental income and landlord obligations. Decide which purchase you are actually making, then check the things that shape it — title structure, shared systems, sound, and who fixes what.

Buying half: what should you verify?
Confirm how the two halves are titled and whether any party-wall or shared-facility agreement governs the roof, driveway, fencing and shared services — and what it says about cost sharing when the roof needs replacing. Ask about the other half: owner-occupied or rented matters for noise, parking and how decisions get made. Inside, check sound transfer through the shared wall, separate furnaces and meters, and whether any work on "your" side ever needs the neighbour's cooperation. Financing a half-duplex is a standard residential purchase for most buyers; the mortgage-side questions for the whole-building version are in my companion post on duplex financing — and as both Realtor and Mortgage Broker I run both sides of that conversation with you.
Buying the whole building: what changes?
Now you are underwriting tenants as well as bricks. Review leases, rents actually paid, and who pays utilities; confirm each unit's legality and safety basics; and price the systems for two households, not one. Resale also differs: your buyer pool becomes investors and house-hackers — people who live in one side and rent the other — which can be a strength in the right location.

Which one fits which buyer?
Half a duplex suits buyers who want detached-like living — a yard, an entrance, no condo fees in many cases — at a price below a comparable detached home; September's semi-detached average in Edmonton was $412,974 against $569,820 for detached (REALTORS® Association of Edmonton). The whole building suits buyers who want rental income to offset their own housing cost and are ready to be landlords. Neither is the "better deal" in the abstract; they solve different problems.

The showing checklist that matters most
Shared wall sound, roof age and responsibility, driveway and parking reality in winter, separate services, and — for whole buildings — the leases, in writing. Five minutes on those beats an hour on finishes.
