Your First Home: Why a smaller deposit shouldn’t become a bigger spending target

James Lucas, director at Barcadia Media, says the government's new mortgage scheme could help first-time buyers purchase the same home with less mortgage debt, or take the same mortgage and buy somewhere more expensive - but warns brokers will need to make the consequences of that choice explicit.

The government's new Your First Home scheme could give first-time buyers a useful choice: less mortgage debt on a suitable home, or a more expensive home with similar borrowing. 

Both may be sensible, but they don’t deliver the same improvement in the household budget.

That distinction deserves a place near the front of the conversation about Your First Home. Otherwise, a policy designed to help people into ownership could quietly become a new instruction about how much they ought to spend. The brochure will display the larger kitchen, but the emergency fund may struggle to get a photograph.

Announced last month, Your First Home will support first-time buyers in England purchasing eligible new-build homes with a 2.5% deposit and a 20% government-backed equity loan. There would be an initial interest-free period, with additional income limits, local price caps and implementation details set to be confirmed in this month's Budget. 

The mechanism offers more than deposit relief. On the proposed structure, the mortgage would cover the remaining 77.5% of the price. For the same property, that means less mortgage borrowing than a conventional 95% mortgage, as well as less cash required upfront. Assuming comparable rates and terms, the initial mortgage payment would be lower. That is a meaningful benefit for someone whose rent has made saving painfully slow.

But it can be used differently.

More choice, or more breathing space?

Analysis by Rightmove estimates that the number of currently available new-build homes within reach of an average solo first-time buyer in England could increase by 114%. This assumes borrowing at 4.5 times average annual earnings and compares the proposed scheme with a standard 5% deposit purchase.

The mortgage ceiling stays the same, but adding the equity loan lets that mortgage support a higher purchase price. At the model’s maximum, the buyer hasn’t reduced their mortgage principal. They’ve bought more house with it, alongside another financial obligation.

There’s nothing inherently wrong with that. A home that accommodates a growing family, or avoids an early move, could justify the choice. Moving has costs too. The useful question is whether the additional purchase price buys lasting suitability, or simply consumes the breathing space the scheme might otherwise create.

“Affordable” does rather a lot of work in property marketing. Sometimes it means a lender might approve the loan. Sometimes it means the household can live comfortably after paying it. Those definitions can share a postcode without sharing much else.

The scheme's benefit has several claimants

The government is candid that the scheme also aims to support new-build demand and housing supply. Developers are expected to contribute to its costs. Their participation, the contribution required and the eventual price caps will matter to which homes buyers can actually choose.

Here is the commercial tension. Support that lifts purchasing power can help developers sell, giving them confidence to build. Where additional supply responds slowly, some benefit could instead be absorbed into prices or reduced incentives. That is a risk arising from the mechanism, not a demonstrated outcome of a scheme whose rules haven’t been finalised.

Nor does it justify dismissing equity loans altogether. The National Audit Office’s June 2019 review found that evaluations of Help to Buy showed increased home ownership and housing supply. It also highlighted market risk and the potential for negative equity, exacerbated by the new-build premium. The precedent supports a serious design discussion, rather than an automatic verdict for or against its successor.

For the buyer, the equity loan needs its own explanation. Under the earlier Help to Buy arrangements, redemption was linked to the property’s value, rather than simply the original cash advanced. Your First Home’s detailed repayment terms have yet to be set out. Brokers shouldn’t import the old scheme’s rules into the new one. They should explain why an initially interest-free loan still requires a plan for later charges and repayment.

That makes the comparison with an existing home essential. A lower-priced resale property without an equity loan may leave a different combination of mortgage payments, maintenance costs and future liabilities. A new-build may suit the client better. The answer requires actual properties and actual budgets, not competing slogans.

For a solo buyer, retaining cash after completion can be particularly valuable, as there’s no second income to absorb a disruption. Advisers should establish the comfortable payment before discussing the maximum purchase price, then include service charges where applicable, essential expenditure and the cost of maintaining a reserve. Once the rules exist, they can test the equity-loan exit alongside the mortgage refinance.

Before the Budget

The Budget on 28th October should provide the missing scheme detail. Over the next fortnight, the useful work is to compare viable options now and identify precisely what a client would need the proposed scheme to change. Waiting may be reasonable, but it carries rent and timing costs; an announcement supplies no completion date.

The best use of extra purchasing power will sometimes be a better home. Sometimes it will be a smaller mortgage and money left in the bank. Good advice should make both visible, before the maximum becomes the target.
