Some changes lift value. Rezoning that permits infill or higher density on your block can make your lot worth more for what could replace the house than for the house itself, and a new school, park, grocery anchor or transit improvement nearby usually helps. Buyers pay for convenience and for the sense that an area is being invested in rather than left alone.
Others cost you. A four storey building overlooking a back yard that used to face a bungalow removes privacy and sunlight, and a development that adds traffic, loses on street parking or introduces commercial hours next to a residential lot is a genuine deduction. Construction itself is a temporary problem with a real price, since a house listed beside an active site shows worse than the same house a year later.
The practical move is to find out what is actually approved before you price anything, then disclose what you know. At 1.63 months of supply Saskatoon buyers still have choices, and one who discovers a proposal after conditions are removed becomes a problem.
