HOMES AND MORTGAGES

I currently hold ETFs and have funds in offset accounts. Ignoring market fluctuations and tax implications, at what point does it make sense to shift money between the two? For example: - If interest rates are very low, I assume ETFs are the better option. - If interest rates are high, it seems smarter to focus on offsetting loans. Is the math as simple as ETFs returning ~7%, so you’d start selling once interest rates cross ~6%, given the higher risk of ETFs compared to loan savings? Would love to hear your thoughts!
