Delays Impact: Weather, labor shortages, or permit delays can extend the timeline and increase holding costs.
Planning for carrying costs ensures a smoother financial experience during the construction phase.
Financing Your Custom Home
Understanding financing options is crucial:

Progress Draw Mortgages: Funds are released at key stages of construction. Common in Canada and supported by major lenders.
