Lease Length: The Silent Factor in Property Devaluation


In the intricate tapestry of the UK property market, the remaining term of a leasehold is a crucial thread that can significantly affect property value. When it comes to property valuation, the duration of the leasehold can be a significant determinant of value. In the UK, where leasehold properties are common, the lease length can be directly proportional to the property’s desirability and market price.

If you’re pondering the impact of a short lease on your property’s worth, it’s prudent to book a free rental valuation on your property to gauge its current market position. This initial step can provide essential insights into how a short lease might affect your property’s market value and inform your decisions moving forward.

The Dynamics of Lease Length:

Leasehold properties, prevalent across England and Wales, often experience a depreciation in value as the lease term shortens. This is particularly acute as the lease falls below 80 years, at which point the cost of extending the lease can increase dramatically due to the so-called ‘marriage value’. This is a component of the valuation that comes into play when the lease drops under 80 years, reflecting the added value of combining the leasehold and the freehold interest.

Valuation Variance Due to Lease Length:

The devaluation effect of a short lease is not linear; it accelerates as the lease term diminishes. A property with a 70-year lease might be worth up to 10% less than one with a 99-year lease, and this discrepancy grows wider as the lease nears the critical 60-year threshold. As leases approach the 30-year mark, the value might only be a fraction of its freehold counterpart, often making such properties cash-buyer only prospects.

Marketability Constraints and Mortgage Hurdles:

Short leases pose a dual challenge: they are less attractive to potential buyers and also to mortgage lenders. Mortgage companies have stringent criteria regarding lease length – most will not lend on properties with less than 70 years remaining on the lease. Consequently, sellers of short lease properties often find themselves limited to cash buyers, significantly reducing the pool of potential purchasers.

Assessing the Financial Impact:

Valuing a short-lease property is complex. It involves understanding the nuances of property law and the current property market. Professional valuers use a formula dictated by the Leasehold Reform, Housing and Urban Development Act 1993, which considers the capitalisation of ground rent, deferment rate, and the aforementioned marriage value. The cost of extending a lease can be prohibitive, especially in prime locations with high ground rents.

Strategies to Combat Devaluation:

Homeowners can take several steps to mitigate the devaluation effect of a short lease:

Lease Extension: This is the most straightforward solution, although potentially costly. It can, however, significantly enhance the property’s saleability and value.

Collective Enfranchisement: If the property is a flat, leaseholders may collectively purchase the freehold, thereby controlling the future of the building and potentially extending their leases cost-effectively.

Selling at Auction: This can be a good strategy to attract a broad base of buyers, including those looking for investment opportunities.

Targeted Marketing: Marketing the property to a specific segment, such as property developers or investors, who may value the potential of the property more than the lease term.

Navigating the Valuation and Sale Process:

It’s essential for sellers to engage with a knowledgeable estate agent and an experienced solicitor specialising in leasehold properties. They can provide guidance through the complex process of valuation and sale, ensuring the property is presented to the market in the best possible light, despite the short lease.

Legislative Context and Future Changes:

The UK government has indicated potential changes to leasehold legislation, including making it easier and cheaper for leaseholders to buy their freehold or extend their lease. Keeping abreast of these developments is crucial, as they could affect the valuation and sale strategy.


A short lease can significantly devalue a property, but the exact impact varies widely depending on specific circumstances. Obtaining a free rental valuation and seeking expert advice is the first step towards understanding and mitigating this impact. With the right approach, leaseholders can navigate the complexities of the market and legal system, potentially adding value to their property or achieving a successful sale in spite of a short lease term.
