AI summary

An interest-only mortgage provides lower short-term repayments by only covering interest costs for a set period, typically up to five years. This can benefit property investors for tax purposes or homeowners needing temporary cash flow for renovations or financial hardship.

However, these loans carry significant risks. You won't reduce your principal, leading to higher total interest costs over the life of the loan. Repayments will also increase substantially when the interest-only period expires. Always seek professional financial advice first.
