No — and there is likely a significant difference between your home’s replacement cost and its market value.
Replacement cost is the amount it would cost to rebuild your home from the ground up, including materials and labour, in the event of a total loss.
Market value is the amount a buyer might pay for your existing home, factoring in location and demand — it doesn’t consider how much it would cost to build the same home with today’s material and labour costs.
When it comes to insurance, your sum insured should be based on replacement cost, not market value.
