New-Build Super-Prime Apartments: Incentives, Stage Payments & Valuation Gaps

Wesley Ranger • 3 September 2025

How lenders assess new-build luxury developments in Mayfair, Knightsbridge, and Belgravia—where incentives can distort values, stage payments complicate cashflow, and valuation gaps threaten finance.

The Evolution of Super-Prime New Builds


Prime Central London has always been defined by its heritage buildings, but in recent years a wave of new-build super-prime apartments has transformed the market. Developments in Mayfair, Knightsbridge, and Belgravia now offer state-of-the-art amenities—concierge teams, wellness spas, cinemas, private dining rooms, and secure underground parking.


For international buyers, these developments offer a ready-made lifestyle: turnkey apartments that require no renovation, with services designed to rival five-star hotels. Yet for all their appeal, financing super-prime new builds presents challenges that are distinct from traditional freehold townhouses or mansion block flats. Lenders scrutinise incentives, stage payment structures, and valuation risks carefully, and buyers who fail to plan ahead can find themselves caught out.


The Problem with Incentives


Developers in the super-prime sector often offer incentives to encourage sales. These may include contributions to Stamp Duty, free service charges for the first year, or even furnishing packages worth hundreds of thousands of pounds.


While attractive to buyers, lenders see these incentives differently. Surveyors are required to assess the “true market value” of the property, excluding the value of incentives. This can result in down-valuations, where the purchase price exceeds the lender’s assessment.


We have seen this issue before in our work on valuation gaps, where mismatches between price and valuation undermine finance. In the super-prime new-build sector, incentives are one of the biggest drivers of such gaps.


Stage Payments and Cashflow Pressures


Unlike second-hand purchases, many new-build transactions require stage payments. Buyers often exchange off-plan, paying a deposit upfront and further instalments as construction progresses. By the time completion arrives, a significant portion of the purchase price may already have been paid.


This structure creates financing challenges. Bridging loans may be needed to cover stage payments, but not all lenders are comfortable funding part-completed units. For international buyers, managing FX risk alongside staged funding adds further complexity.


We explored similar issues in our article on development finance. While that piece focused on developers, the lesson for buyers is the same: staged finance must be structured with lender appetite, construction timelines, and exit strategies in mind.


The Valuation Gap Dilemma


Perhaps the most significant risk in financing super-prime new builds is the valuation gap. Off-plan buyers may agree a purchase price two or three years before completion. In that time, market conditions can change.


If the market softens—or if surveyors are cautious—valuations at completion may fall short of the agreed price. Buyers then face the prospect of funding a larger deposit or being unable to complete at all.


In our Prime Central London market updates, we’ve noted how lenders are adopting a conservative stance. For super-prime new builds, this means valuations are often 5–10% below agreed prices, particularly where incentives are generous.


International Buyers and Credit History


Many new-build super-prime buyers are international clients. While their global wealth may be substantial, they often lack UK credit history. This can make securing finance more difficult, especially with mainstream lenders.

Private banks are typically more accommodating, assessing wealth holistically and valuing the long-term relationship. However, they still require robust documentation and comfort around source of wealth. This is consistent with themes we explored in foreign national mortgages, where structuring around offshore income and assets was essential.


Bridge-to-Term Solutions


One strategy that has become increasingly common is the use of bridging finance at completion, followed by a refinance into a long-term mortgage once the property is registered. This approach allows buyers to meet contractual deadlines even when valuations or lender processes cause delays.


As we explained in our guide to bridging to mortgage strategies, careful sequencing is key. Without a credible exit, bridging becomes an expensive stopgap rather than a solution. For super-prime new builds, where sums can exceed £10 million, the stakes are high.


The 2025 Lending Environment


As of 2025, lenders remain selective about super-prime new builds. While private banks are open to funding at scale, they are cautious about inflated purchase prices and unproven schemes. Specialist lenders have entered the space, but they too demand clear evidence of value sustainability.


At the same time, international demand remains robust. As noted in our work on currency opportunities, fluctuations in the pound create buying opportunities that drive off-plan purchases. The challenge for buyers is not demand, but execution—ensuring finance aligns with both construction schedules and lender appetites.
