It is not a second inspection. You are confirming the home is substantially as it was when you wrote the offer — before the money moves.
In most Calgary transactions your right to view the property before possession is written into the purchase contract, so it is a term of the deal rather than a favour. It is commonly arranged for the day before possession, once the seller has moved out and while there is still time to act on what you find.
Its purpose is narrow and worth being clear about: you are confirming the home is in substantially the condition it was in when you wrote the offer, that everything the contract includes is present and working, and that nothing was damaged on the way out. It is not an opportunity to reopen the price over things you already knew about.
Do it before the funds are released. Afterwards you are not adjusting a deal any more — you are pursuing a seller.
Call your REALTOR® immediately, and your lawyer, while money is still on your side of the table. There is real leverage in that window and very little afterwards. Photograph everything, in place, before anyone tidies. The full sequence from firm to keys is in our Alberta closing timeline guide.
