A mortgage option many borrowers assumed was fading into history is making a comeback, and I don’t think it will go unnoticed by the wider market.
Competition between lenders has largely centred on fixed-rate pricing in recent years.
A lender cuts a two-year or five-year deal, moves up the sourcing tables, and its competitors respond.
That battle is still running, but the latest move I’ve seen suggests it’s no longer the only game in town.
West Brom Building Society has just brought interest-only and discount variable mortgages back into its residential range, alongside cuts of up to 0.24 percentage points on selected three-year and five-year purchase rates.
What makes the announcement notable is that the society isn’t competing on fixed rates alone.
It’s giving borrowers more choice over how their mortgage is structured, and that could be where the next phase of competition is heading.
Will other lenders follow?
Some will. Not everyone, and not overnight.
When a competitor starts attracting business in an area where choice has been thin, rivals pay attention.
If brokers begin placing more interest-only or discount variable cases with West Brom, the rest of the market will want to know whether they’re missing genuine demand.
My money’s on the building societies and smaller specialist lenders moving first. They can’t always compete with the big banks on price alone, so a broader product range is one of the few levers they have.
The little-known mortgage option quietly making a comeback

GETTYWhy interest-only matters
West Brom’s new interest-only purchase product is available up to 60 per cent loan-to-value at 4.66 per cent, while the remortgage equivalent is priced at 4.88 per cent with £500 cashback.
These won’t suit everyone, but for borrowers with substantial equity, irregular income or a defined repayment strategy, the flexibility is real.
Interest-only lowers the monthly payment because the borrower isn’t paying down the balance each month.
That’s where the caution has to sit, though.
The capital still has to be repaid, and lenders will normally want to see a proper repayment vehicle, investments, pensions, savings, or the planned sale of another property.
Interest-only should never be the thing that makes an unaffordable mortgage look affordable on paper.
Competition between lenders is heating up

GETTYDiscount variable carries a different risk
The purchase product here is available up to 90 per cent loan-to-value at 4.49 per cent, with the remortgage option at 4.60 per cent.
Borrowers benefit if the society’s standard variable rate falls, but nothing is guaranteed to stay where it started.
That 90 per cent LTV option matters, because it gives buyers with a 10 per cent deposit another way into the market, and it puts affordability front and centre for exactly that group.
Smaller deposits mean less room to absorb a payment rise if rates move the wrong way.
More choice, but suitability still comes first
This launch is a good thing. The market works better when borrowers and brokers have a wider range of credible options in front of them, rather than a shrinking list of fixed-rate deals that all look the same.
Fixed rates will keep dominating.
But I expect to see more lenders competing on flexibility over the next year, not just price, and West Brom has just put down a marker.None of that changes what actually matters for the person signing the paperwork.
An interest-only mortgage needs a real repayment plan behind it.
A discount variable needs a household budget with enough give in it to absorb a rate move. Get either of those wrong, and the lowest headline rate in the world won’t save you.
