Premium finishes: Features such as granite countertops, upgraded windows, or exterior siding also increase overall costs.
Delivery fees: Costs vary by distance—buyers in Northern Ontario often pay more than those in the GTA.
Land preparation & utilities: Clearing, grading, septic installation, water, and hydro connections can add $10,000–$50,000+, depending on site conditions.

Construction loans: Funds are often released in stages (factory build → delivery → final setup).
Appraisals: Lenders typically require an appraisal of both the home and the land.
