Should You Stretch Your Deposit to Reach a Better LTV Band?

Moving into a lower LTV band by increasing your deposit can meaningfully improve your mortgage rate - but only when the maths works and enough cash remains for fees, moving costs, and a buffer. When it empties your reserves or relies on everything going perfectly, it can create more risk than it removes.

When crossing a band makes financial sense

A clean step down from 80% to 75% LTV with cash left over often produces a rate improvement that pays back quickly.

When it probably does not

Stretching the deposit to cross a threshold is counterproductive if it leaves you cash-poor at completion or removes the buffer for early ownership costs.

The valuation risk to account for

If the lender values below the agreed price, you may need more cash than planned to maintain your target LTV.
