£200,000 for a two-bed flat in Mayfair?

You must be joking.

That was the first thought that went through my mind while walking through Mayfair and looking in the windows of estate agents. A two-bedroom flat in Mayfair for around £200,000 looked absurd. Then I read the fine print.

There were only around 20 years left on the lease.

The likely lease extension premium was around £1.5 million. Once extended, however, the property could be worth upwards of £3 million. It was in a stellar location, in excellent condition, and on the surface had the kind of discount that makes every property investor stop and look twice.

That was the moment the strategy started to click.

The problem with short lease flats is not that they are always bad assets. Often, they are good assets trapped inside a legal structure that limits buyer demand, lender appetite and marketability.

The market problem with short lease flats.

Short lease properties have historically sat in an awkward part of the market. The flat may be in a strong location. It may be in good condition. It may have strong long-term demand. But if the lease is short, the pool of buyers becomes smaller.

Owner-occupiers often cannot proceed because mortgage lenders may not support the purchase. Investors may look, but many will avoid the complexity.

Bridging lenders may consider short lease flats, but traditionally they have treated them with caution. There may be potential value, but the process to unlock that value feels uncertain, legal-heavy and time-sensitive.

The reform moment.

The market began to change because leasehold reform was moving up the agenda.

The Leasehold Reform (Ground Rent) Act 2022 had already changed the landscape for most new long residential leases by restricting ground rent to a peppercorn. The Leasehold and Freehold Reform Act 2024 then pointed towards further reform, including longer statutory lease extensions and improved leaseholder rights.

The detail and timing of legislation must always be checked on a live case. Leasehold law is technical, and different provisions can come into force at different times. Investors should always take professional legal advice before relying on any reform position.

However, the direction of travel was clear. Lease extensions were becoming easier to think about as a structured investor strategy.

The idea started with value trapped by structure.

A property could be cheap because the lease was short. That same property could be significantly more valuable once the lease was extended. The value was not being created by bricks, paint or planning. It was being created by a legal improvement to the asset.

We had already launched our title split strategy, which lent against uplifted split value. Title split finance was built around a similar concept: lending against value created by a legal process. In title splits, the process creates new leasehold titles. In lease extensions, the process improves an existing lease.

That made lease extension finance feel like a natural next product.

The first product logic.

The first version of the idea was straightforward. We could look at 75% of the extended value, supported by a surveyor, and allow that to fund up to 100% of the purchase price.

That alone was useful, but it did not solve the whole problem. The lease extension premium itself can be significant. Without finance for the premium, the strategy would only be useful to investors with substantial capital.

That led to the next question. If the lease extension premium is the cost required to create the extended value, why not treat it like a value-creation cost?

In a refurbishment loan, a lender may fund works because those works help create the GDV. In lease extension finance, the premium plays a similar role. It is the cost of unlocking the extended value.

• 75% of extended value.
• Capped at 100% of purchase price.
• Capped at 100% of lease extension costs.
• Works funding considered where the GDV uplift supports it.

What is lease extension finance?

Lease extension finance is specialist short-term funding for investors acquiring or refinancing leasehold property where value is expected to be created by extending the lease.

The finance is structured around three core values: current value, extended value, and improved extended value or GDV where works are also planned.

A standard bridge may look mainly at the current position. Lease extension finance looks at the completed value-creation plan. That requires a different underwriting mindset.

Why short leases create investor opportunity.

Short leases reduce demand. As the remaining term falls, mortgageability becomes harder, buyer confidence weakens and pricing becomes less efficient.

For many buyers, this creates too much complexity. For investors, complexity can create opportunity.

The strategy is to buy an asset at a discount because the lease is short, extend the lease, then either sell, refinance or retain the property based on the improved value.

1. The property becomes more mortgageable.
2. The buyer pool widens.
3. Ground rent may be reduced or removed depending on the route and terms.
4. The asset becomes easier to sell or refinance.

How the uplift is assessed.

The uplift comes from comparing the flat’s market value with its current short lease against its market value with the lease extended.

A proper valuation needs evidence. That usually means comparable sales of similar flats with similar lease lengths, where available, and comparable sales of long lease or extended lease flats in the same block or local market.

Adjustments matter. Size, condition, floor level, outlook, building quality, service charge, ground rent, lease terms and location all affect value.

The lease extension premium.

The lease extension premium is the price paid to the freeholder to extend the lease. It is usually one of the most important numbers in the whole strategy.

The premium may be affected by remaining lease length, current property value, extended lease value, ground rent, capitalisation and deferment rates, marriage value where applicable, valuation methodology and negotiation risk.

This is why lease extension strategy is not simply about spotting a cheap flat. The real question is whether the cost of extending the lease still leaves enough profit, refinance capacity or retained equity after all costs.

Statutory vs informal lease extensions.

There are two broad ways to extend a lease. The formal statutory route gives legal protections and a defined process. The informal route involves negotiating directly with the freeholder and can sometimes be faster, but it may not offer the same protections.

For investors, the route matters because lenders care about certainty. A fast informal agreement may be attractive, but only if the terms genuinely improve value and marketability. A statutory route may offer stronger protections, but timing and process need to be modelled properly.

The professional team.

Lease extension finance requires coordination. A typical deal may involve the borrower, conveyancer, lease extension solicitor, specialist valuer, lender’s valuer, lender’s solicitor, freeholder, freeholder’s solicitor and lender.

If these parties are not aligned, delays can appear quickly. That is why preparation matters.

What can go wrong.

• The premium is higher than expected.
• The freeholder delays or negotiates aggressively.
• The lease contains defects.
• Ground rent terms weaken marketability.
• Service charge, reserve funds or building management issues damage investor economics.
• Building safety or repair issues affect lender appetite.
• The extended value is not supported by comparable evidence.
• The exit depends on a refinance that rental income cannot sustain.
• The legal route takes longer than expected.

How Finanze Capital underwrites lease extension finance.

Finanze Capital looks at the extended value upfront. That is the key difference.

Instead of only asking what the property is worth today with a short lease, we ask what the property can be worth once the lease extension has been completed and the legal position improved.

That does not mean accepting optimistic numbers. It means reviewing current value, extended value, premium estimate, professional costs, lease terms, legal route, valuation evidence, borrower profile and exit strategy.

The funding waterfall.

1. Start with the supported extended value.
2. Apply the relevant loan-to-extended-value percentage.
3. Assess the purchase price, extension premium and professional costs.
4. Allocate net funds across the transaction.
5. Where works are involved, consider whether GDV supports additional lending.
6. Stress test the exit route, sale, refinance or blended strategy.

Worked example 1, purchase plus lease extension.

Take a property with a purchase price of £500,000. The lease extension premium is £100,000. The extended value is £1,000,000.

At 75% of the extended value, the gross lending capacity is £750,000. That can create enough capacity to support 100% of the net purchase price and fully fund the lease extension premium, subject to costs, valuation, legal review and underwriting.

Worked example 2, purchase, lease extension and works.

Now take a property with a purchase price of £450,000, a lease extension premium of £250,000, works cost of £120,000, extended value before works of £950,000 and projected GDV after works of £1,200,000.

In this kind of structure, the facility may look at both extended value and GDV. The finance may first support works, then the lease extension cost, with the remaining net proceeds going towards purchase.

Exit strategies.

A lease extension strategy needs a clear exit from the beginning. There are usually three main routes: sale after extension, refinance after extension or a blended strategy.

The exit depends on value, income, buyer demand, lender appetite and timing. Lease extension can improve marketability, but that does not remove the need for a sensible exit plan.

What we need to review a lease extension deal.

• Property address and description.
• Purchase price.
• Current lease length.
• Ground rent and service charge details.
• Short lease value.
• Estimated extended value.
• Lease extension premium estimate.
• Specialist valuation or premium advice, if available.
• Comparable sales evidence.
• Proposed statutory or informal route.
• Works schedule and costings, if relevant.
• Borrower background and experience.
• Exit strategy.

Why this strategy matters.

Lease extension finance matters because it turns a trapped asset into a structured opportunity.

A short lease flat may be underpriced because the market sees the problem first. The investor sees the solution. But seeing the solution is not enough. The finance has to match the strategy.

A lease extension strategy is not about buying cheap flats and hoping. It is about understanding legal value, recognising where a short lease has suppressed demand, and structuring finance around the completed position rather than the current limitation.
