When mortgage rates rise, the instinct is to hurry — to buy before they go higher. It is worth sitting with the arithmetic for a moment, because a higher rate environment changes both sides of the equation, and only one of them is bad news.
Your deposit is earning too
The same conditions that make borrowing expensive make saving productive. A deposit sitting in a well-priced easy-access account is compounding at a rate that would have looked generous a few years ago. Six more months of saving is not six months lost.
It also moves you between loan-to-value bands, and that is where the real money is. Crossing from a 90% loan-to-value to 85% typically moves you onto a materially better rate — often worth more over a five-year fix than the extra saved.
Work out your next band, not your target
Instead of aiming at an abstract deposit figure, find the price of the homes you are actually looking at and calculate the deposit that puts you in the next band down. That is a concrete number, usually closer than the one in your head, and it comes with a measurable reward attached.
Where to hold the money
- Money you might need within twelve months belongs in easy access. A fixed term you have to break is a fixed term that has cost you.
- Money you are certain is untouched for a year or more can go into a fixed-term deposit at a higher rate.
- Split the deposit across both if the completion date is uncertain — most are.
Whatever you choose, keep the deposit out of anything whose value can fall. A deposit is not a long-term investment; it is a payment with a date on it.
The honest trade-off
Waiting is not free. Rent is not building equity, prices may move, and life does not pause for an optimal loan-to-value. The point is not that waiting always wins — it is that hurrying is a decision too, and it deserves the same arithmetic.
