Type of Property Guide
A short lease shrinks your buyer pool, reduces your price and can cause conventional sales to collapse during conveyancing. Here is what to expect and what your options are.
A leasehold flat is not owned outright. You own the right to occupy the flat for the duration of the lease term. When that term runs down, the property technically reverts to the freeholder. In practice, leaseholders have legal rights to extend, but the shorter the remaining term, the more complicated and expensive that process becomes.
Most residential leases were originally granted for 99 or 125 years. There are several million leasehold flats in England and Wales (estimates put the figure at 3 to 4 million), a significant proportion of which are now sitting in the 60 to 90 year range and need to be addressed before or at the point of sale.
A lease with fewer than 80 years remaining is generally described as short. This is the critical threshold at which marriage value begins to apply, significantly increasing the cost of a formal lease extension. Below 70 years, most mainstream mortgage lenders will not offer loans to buyers. Below 60 years, a flat is effectively unmortgageable through conventional routes.
The result is a shrinking buyer pool: the shorter the lease, the fewer buyers can purchase with a mortgage, and the more heavily discounted the price needs to be to attract the cash buyers and investors who remain. Everything here is general information rather than legal, financial or tax advice: for advice on your own lease, speak to a solicitor or a leasehold valuation surveyor.
Short leases create four distinct obstacles during a sale. Understanding each helps you set realistic expectations and plan around them.
Mainstream lenders require a minimum lease length on completion, typically 70 to 75 years. Some require 85 years or more. Below these thresholds a buyer's mortgage application will be declined, regardless of their finances. The shorter the lease, the narrower the set of lenders willing to proceed.
Buyers often proceed to offer without fully understanding the lease implications. Once their solicitor reviews the title and their lender reviews the lease, the sale can collapse weeks in. This is one of the most common causes of failed short-lease transactions.
Even within the cash buyer market, short lease flats sell at a discount to their long-lease equivalents. The discount reflects the cost the new owner will face to extend the lease, plus a risk premium for the complication.
Short lease conveyancing involves extra enquiries, reference to the Leasehold Reform Act and sometimes simultaneous lease extension by the seller. Solicitors charge more, timelines extend, and buyers without experience of leasehold can be put off.
Before you decide how to proceed, establish exactly how many years are currently left on the lease. The figure on your original purchase paperwork is no longer current: the lease shortens by one year for each year that has passed since it was granted.
The authoritative source is HM Land Registry. Download your Title Register and the Lease document (£7 each) from the official service at gov.uk/search-property-information-land-registry. The lease document will state the original term and the date it was granted, which lets you calculate the years remaining.
Avoid paid third-party sites that charge more for the same information. Your own solicitor or conveyancer can also obtain this for you, usually as a standard service at the start of a sale.
If the lease has already been extended at some point, the extension will be reflected on the Title Register either as a new lease (for statutory extensions under the 1993 Act) or as a Deed of Variation (for informal extensions). Check the Register carefully before assuming the original term still applies.
Approximate discount ranges compared to an equivalent flat with a long lease. Actual figures depend on location, flat value and specific lease position.
What each lease length means for your sale
As the lease shortens, the buyer pool narrows and the discount deepens.
The flat is still mortgageable for many buyers, but lenders are becoming cautious. Marriage value applies below 80 years. Expect a discount of roughly 5-15 percent versus a comparable flat with a longer lease.
Most mainstream lenders will not lend. The buyer pool narrows significantly to cash buyers, investors and a small number of specialist lenders. Expect a discount of roughly 15-30 percent.
Effectively unmortgageable through conventional routes. Only cash buyers will proceed. Extension costs are high due to marriage value. Expect a discount of 30 percent or more, potentially deeper for very short leases.
Location matters considerably. In London and other strong-demand markets, even short-lease flats retain meaningful value because the underlying property is still desirable. In lower-demand areas, the discount effect can be steeper because the buyer pool was already limited. An experienced leasehold valuer or a specialist cash buyer will give you a realistic figure for your specific flat.
Two main routes are available: extend the lease before marketing, or sell with the short lease as it stands. Both are valid depending on your circumstances.
As an owner of a qualifying leasehold flat, you have a statutory right to extend the lease by 90 years under the Leasehold Reform, Housing and Urban Development Act 1993. The Leasehold and Freehold Reform Act 2024 removed the previous two-year ownership requirement on 31 January 2025, so this right is available from the day you become the registered owner. The extension adds to the existing term and sets the ground rent to a peppercorn (zero). The cost is a premium paid to the freeholder plus your legal and valuation fees.
The advantage: a longer lease widens the buyer pool considerably, allowing mortgage-backed buyers to proceed. A flat with 125+ years on the lease will typically sell for significantly more than the same flat at 60 years, often more than the cost of extending.
The disadvantage: the process takes several months, and below 80 years the premium can be substantial due to marriage value. Get a leasehold valuation surveyor's estimate before committing.
You can sell with the lease as it stands. You disclose the lease length, price the flat accordingly and target cash buyers and investors comfortable with the position. This is faster and avoids upfront costs, but the achieved price reflects the short lease. Lease length, ground rent and service charge are material information: since 6 April 2025 the Digital Markets, Competition and Consumers Act 2024 (DMCC Act) has required them on the listing rather than left to emerge in conveyancing.
Some sellers prefer this route when the extension cost would be very high, when speed is the priority or when a previous sale has already fallen through due to the lease and they want certainty over a higher price.
A middle route: start the statutory extension yourself by serving a Section 42 notice, then assign the benefit of that notice to the buyer as part of the sale. The buyer pays the premium and completes the extension, but the fact that the process is already started removes a major uncertainty for their lender. This is particularly useful when the lease is close to, but still above, 80 years and there is pressure to act before marriage value kicks in.
A lease extension has three main costs: your professional fees, the freeholder's professional fees and the premium payable to them. The premium is almost always the largest and the most variable.
A leasehold valuation surveyor typically charges between £500 and £1,000 to value the premium for a single flat. Your solicitor's fees for the extension process, separate from any sale, generally run from £1,000 to £2,000 plus VAT and disbursements. Under statutory extension rules you are also liable for the freeholder's reasonable legal and valuation fees, typically another £500 to £1,500. A Land Registry registration fee applies at the end.
The premium is calculated by formula rather than negotiation, though the inputs to the formula are open to interpretation, which is why the freeholder's valuation and yours often differ. The key factors are the current lease length, the value of the flat, the ground rent and, below 80 years, marriage value.
Marriage value is the additional value created when you combine your leasehold interest with the freehold. Under the current rules in England and Wales, once the lease falls below 80 years you must pay 50 percent of this marriage value to the freeholder as part of the premium. This can add tens of thousands of pounds to the total, depending on flat value and lease length.
The 80-year cliff: the cost to extend jumps

The statutory route follows the formula in the Leasehold Reform Act 1993 and adds 90 years to the existing term while reducing ground rent to a peppercorn. It is the safer route for most leaseholders because the freeholder cannot refuse and the calculation follows rules.
The informal route is a negotiated extension outside the statutory framework. The freeholder may offer shorter extensions, retain a ground rent or insert terms that are less favourable than the statutory alternative. Informal extensions are cheaper in some cases but carry a real risk of worse lease terms. Always get specialist advice before accepting an informal offer.
A statutory lease extension begins with your solicitor serving a Section 42 notice on the freeholder. This triggers a formal timetable: the freeholder has two months to respond with a Section 45 counter-notice, and then there is a further period to negotiate the premium. Once the notice is served, the freeholder can also require a deposit of 10 percent of the premium you proposed, or £250 if greater, payable within 14 days of their request.
If you and the freeholder cannot agree on the premium, either party can apply to the First-tier Tribunal (Property Chamber) in England, or the Leasehold Valuation Tribunal in Wales, for a determination. This adds time and cost but is sometimes necessary when the freeholder's valuation is unrealistic.
The entire process typically takes four to nine months when uncontested, longer if the premium goes to tribunal. If you need to sell urgently, you can begin the extension process and then transfer (assign) the benefit of the Section 42 notice to the buyer, effectively passing the right to extend to them, which supports the sale price while they complete the extension after purchase.
The Section 42 timeline and its statutory deadlines
The freeholder's clock is fixed by law; the negotiation is where the time goes.

From serving to completion: typically four to nine months, longer if it goes to tribunal.
The previous two-year ownership requirement was abolished on 31 January 2025, so the statutory extension right is available immediately to any qualifying leaseholder. There is no maximum lease length: you can extend a 95-year lease if you want to, though the cost-benefit calculation below 90 years is usually more compelling.
A significant minority of short-lease cases involve a freeholder who is slow to respond, uncontactable or quoting an unrealistic premium. The statutory extension process is designed to deal with these situations, but it adds time and cost.
In difficult cases it is worth selling to a specialist cash buyer who has experience with problem freeholders, rather than putting a retail buyer through the same frustrations. We buy short-lease flats where the freeholder is absent, slow or obstructive, and absorb the subsequent extension work ourselves.
Longer than a typical sale. Three factors extend the timeline:
Realistic expectations by route:
The right route depends on the lease length, the extension cost, your timeline and how tolerant you are of uncertainty. There is no single correct answer.
Whichever route you choose, engage a conveyancing solicitor who handles leasehold extensions and sales routinely. Most high-street conveyancers do not, and the difference in competence is visible within the first two weeks.
The Leasehold and Freehold Reform Act 2024 (often shortened to LAFRA) was passed into law in May 2024. Among other provisions it is expected to abolish marriage value and reduce the cost of lease extensions, potentially by significant amounts for leases below 80 years.
However, as of July 2026 the secondary legislation required to bring the key financial provisions into force has not been enacted. Freeholders challenged the reforms in court, but the High Court dismissed that challenge in October 2025, so the Act itself stands. Even so, no commencement date has been set for the valuation changes: the realistic expectation is now late 2026 at the earliest, with 2027 or 2028 widely seen as more likely. Consultation on the detailed valuation framework is ongoing.
Waiting for reform carries two real risks:
This is a decision worth specialist advice on. The Leasehold Advisory Service (LEASE) provides free guidance on leaseholder rights and the current state of reform. A leasehold solicitor or valuation surveyor can model the numbers for your specific lease under both current and expected post-reform frameworks.
For sellers who cannot wait, the practical approach is to proceed on the current rules and treat any future reform benefit as upside for the buyer. Pricing the flat on today's reality is usually sounder than betting on a timeline that is not yet fixed.
If you want to sell without extending the lease first, we buy short lease flats for cash, including those with fewer than 60 years remaining. No mortgage lender to satisfy, no public viewings, no chain. We price the lease length into our offer from the start, rather than reducing it later once solicitors get involved.
We handle difficult freeholders, absent freeholders and leases with awkward ground rent clauses as part of our normal process. The trade-off is a price below open market value, in exchange for certainty and speed.
How we buy short lease flats →A lease with fewer than 80 years remaining is generally considered short. This is the threshold at which marriage value becomes payable, significantly increasing lease extension costs. Below 70 years, most mainstream mortgage lenders will not lend. Below 60 years, the flat is effectively unmortgageable for most buyers.
It depends on the cost of extending versus the price uplift it achieves. As an owner of a qualifying leasehold flat, you have a statutory right to extend at any point: the two-year qualifying period was abolished by the Leasehold and Freehold Reform Act 2024 on 31 January 2025. A leasehold valuation surveyor can advise whether extension is financially worthwhile for your specific flat. Below 80 years, costs rise sharply due to marriage value.
Approximate ranges: 70 to 80 years remaining, 5 to 15 percent below comparable long-lease properties. 60 to 70 years, 15 to 30 percent discount. Below 60 years, 30 percent or more. These are broad guides. The actual discount depends on the local market, flat value and how far below 80 years the lease sits.
Marriage value is the additional value created by combining the leaseholder's and freeholder's interests. Under the current rules in England and Wales, when a lease falls below 80 years the leaseholder must pay the freeholder 50 percent of this marriage value as part of the lease extension premium. This significantly increases extension costs. The Leasehold and Freehold Reform Act 2024 is expected to abolish marriage value, but as of July 2026 the relevant provisions are not yet in force.
The Act passed into law in 2024, but many provisions including the abolition of marriage value require secondary legislation that had not been enacted as of July 2026. Waiting carries a real risk: the lease continues to shorten, and if it drops below 80 years while you wait, the extension cost increases substantially. This decision benefits from specialist leasehold advice on your specific position.
Longer than a typical sale. A conventional sale through an estate agent commonly takes 3 to 6 months from listing to completion, compared with 8 to 12 weeks for a straightforward flat sale. Cash buyer routes can complete in 3 to 6 weeks. Auction routes complete within 28 days of the hammer falling. The main causes of delay are mortgage enquiries, additional solicitor scrutiny of the lease and buyers withdrawing once they understand the implications.
The buyer pool narrows as the lease shortens. Typical buyers include specialist cash buyers, experienced property investors who model the extension cost into their yield, property developers and auction buyers comfortable with short-lease stock. Owner-occupier buyers with mortgages typically drop out below 70 years.
Yes, but choose an agent experienced in leasehold. An inexperienced agent may overvalue the flat, attract unsuitable buyers or fail to manage the complications that emerge during conveyancing. Short-lease sales are prone to fall-through when buyers' solicitors flag the lease length and the buyer's lender withdraws. A specialist agent will price honestly, target appropriate buyers and manage expectations on both sides.
