Top 10 Questions About Selling a Short Lease Flat
If your lease has 80 years or fewer left, this page answers the questions sellers ask most. What counts as short, if you can still sell, how it affects the price, when to extend first, which buyers can get a mortgage, who buys and how to set your price. The answers reflect the law in England and Wales as it stands in 2026.
Short Lease Sales: The Full Picture
A short lease changes how a flat sale works, but it does not stop one. Three things change:
- Mortgages. Lenders set a minimum lease length, so some buyers cannot borrow against the flat.
- Extension cost. At 80 years or fewer, marriage value applies. This is the extra sum a freeholder can claim when a short lease is extended, and it makes extending more expensive.
- Buyers. The likely buyers shift towards investors and cash buyers.
Each of these is well understood, and you can plan around them. For the sale itself, step by step, see our guide to selling a short lease flat.
This page works through the ten questions sellers ask most once they realise their lease is short. The answers reflect the law as it stands in 2026:
- the lease extension rules in the Leasehold Reform, Housing and Urban Development Act 1993 (the 1993 Act)
- the abolition of the two-year ownership rule on 31 January 2025, so you can start an extension as soon as you own the flat
- the Leasehold and Freehold Reform Act 2024 (LAFRA), which would abolish marriage value but is not yet in force on that point
Where the rules may change, the page says so.
Sell Flat UK is a cash buyer of leasehold flats, including short lease flats. A cash sale is one route among several. Where extending the lease and then selling through an estate agent would leave you better off, the page says so. Where auction is the better fit, it says so too. This guide is general information, not legal, financial or tax advice. Check your own position with a solicitor or a qualified adviser.
1. What Is Considered a Short Lease in the UK?
A lease is usually called short once it has 80 years or fewer left. That is the point at which marriage value, the extra sum the freeholder can claim on a lease extension, starts to apply under the 1993 Act, so it is the figure most people have in mind. Other thresholds matter too, for different reasons:
- Above 90 years: most lenders are comfortable, and the lease length has little effect on the sale.
- 80 to 89 years: still mortgageable with many lenders, but close to the 80-year line. It is worth pricing an extension now, while the cost is still moderate.
- Below 80 years: marriage value applies to any extension, and the cost of extending rises sharply.
- Below 70 years: mainstream lenders usually withdraw. The likely buyers are cash buyers and specialist investors.
- Below 60 years: very few ordinary buyers can proceed. Most sales go to cash buyers or through auction.
Where does your lease sit?

80 to 89 years. Still mortgageable with many lenders, but close to the 80-year line. It is worth pricing an extension now, while the cost is still moderate.
These rules apply in England and Wales only. Scotland converted its remaining long leases to outright ownership in 2015, and Northern Ireland has its own system, so neither the thresholds nor the 1993 Act rules on this page apply there.
2. Can I Sell a Flat With a Short Lease?
Yes. Hundreds of short lease flats sell every week in England and Wales. The difference is that fewer buyers can proceed, so the route to a sale is narrower than for a long lease flat.
What changes:
- Fewer buyers can get a mortgage. How many depends on the lease length.
- The likely buyers are cash buyers, buy-to-let investors, developers and people ready to pay for a lease extension after they buy.
- The price is lower than for a similar flat with a long lease. The discount covers the buyer's future extension cost and the fact that fewer buyers are competing.
- Marketing works better when aimed at investors than at the general public.
What does not change:
- The legal steps are the same: contract, exchange and completion.
- You still need a solicitor. The buyer will usually want a survey, and if they need a mortgage their lender will value the flat and check the lease length.
- Once you accept an offer, the legal work takes the same time as on any sale.
Selling is rarely the problem; the price and the route are what matter. Our guide to the steps to take when selling a short lease flat covers the process, and the options hub compares the routes.
3. How Does a Short Lease Affect Value?
The shorter the lease, the bigger the discount compared with a similar flat on a long lease. The bands below come from how valuers work in England and Wales. They are rough guides; the real discount depends on the flat.
- 90+ years: little effect on value, usually under 2 percent.
- 80 to 89 years: 5 to 10 percent below a flat with 99 years or more.
- 70 to 79 years: 10 to 20 percent below. Marriage value, the extra sum the freeholder can claim on an extension below 80 years, is the main reason.
- 60 to 69 years: 15 to 25 percent below, because mainstream lenders have mostly gone.
- Below 60 years: 25 percent or more below, and almost all buyers are cash buyers.
Four things move the figure within those bands:
- The flat's value. A higher-value flat pays a bigger premium in pounds, but the premium is often a smaller share of the price.
- The location. Where cash buyers and investors are thin on the ground, the discount is larger.
- The freeholder. Some freeholders open negotiations high or resist agreeing terms. Buyers then price in the cost of taking the case to a tribunal.
- Other problems with the lease. A high ground rent, a building safety issue or a no-subletting clause on top of a short lease adds to the discount.
For a worked example of the marriage value calculation, see our marriage value guide.
4. Should I Extend the Lease Before Selling?
It can be worth doing, but check the figures first. The likely increase in the sale price needs to cover the cost of extending, professional fees and any extra costs of waiting to sell.
Get advice early if your lease is approaching 80 years. Under current rules in England and Wales, an extra payment called "marriage value" applies when 80 years or fewer remain at the date you serve the formal notice. This payment is linked to the value gained by extending the lease. LEASE (the Leasehold Advisory Service) explains the rules.
Reasons to extend first
- More potential buyers. A longer lease can make it easier for buyers to get a mortgage.
- A better price. Extending can increase the flat's value, although the amount varies.
- Less for the buyer to organise. They will not need to arrange an extension soon after buying.
Reasons to sell without extending first
- Time. The formal process can take several months or longer. A dispute over the price or terms can add delays.
- Cost. You pay the extension price, known as the premium, plus legal and valuation fees. Under the current statutory rules, you also pay the freeholder's reasonable legal and valuation costs.
- Upfront funding. If you finish the extension before selling, you need to fund it before receiving the sale proceeds.
- Uncertainty. The final cost may exceed the initial estimate, and a higher sale price is not guaranteed.
How to decide
Ask a surveyor who specialises in lease extensions to estimate the premium, and get quotes for the professional fees. Then ask local estate agents what the flat could sell for with its current lease and with an extended lease.
Compare what you would keep from each option after costs. Also consider whether you can afford the extension and wait for it to finish.
5. Can the Buyer Extend the Lease Instead?
Yes. In England and Wales, an eligible buyer (one whose lease was originally granted for more than 21 years) can start their own lease extension or take over a claim you have already started.
Route 1: The buyer starts after buying
The buyer purchases the flat with its existing lease and starts the extension once they are the registered owner. They pay the extension price, known as the premium, and the associated fees. You receive the agreed sale price for the flat as it stands.
The buyer starts the formal process by serving a Section 42 notice (the formal notice under the 1993 Act that starts a statutory lease extension). They no longer have to wait two years: that rule ended on 31 January 2025.
Route 2: You start the process and the buyer takes over
You serve a valid Section 42 notice before selling. Your solicitor then transfers the benefit of the claim to the buyer when the sale completes. The buyer finishes the extension and pays the premium. Agree who pays the other costs as part of the sale.
This preserves the original valuation date. The flat's value and remaining lease length are assessed at the date your notice was served. The final premium still needs to be agreed or determined, and the legal deadlines continue to run.
The two routes, step by step
Both end with the buyer paying for a 90-year extension. The difference is who serves the notice, and when.
Route 1 The buyer starts after buying
-
The buyer completes the purchase
They buy the flat with its existing short lease and pay you the agreed price.
-
No two-year wait since 31 January 2025
The buyer is registered as owner
Once HM Land Registry records them as the leaseholder, which can take a few weeks, they can start straight away.
-
The buyer serves a Section 42 notice
This starts the statutory extension in their name. The premium is worked out as at the date of their notice.
-
The buyer agrees and pays the premium
Plus their own legal and valuation fees, and the freeholder's reasonable costs.
-
Lease extended by 90 years
Ground rent reduced to nothing.
Route 2 You start, the buyer takes over
-
Valuation date fixed here
You serve a valid Section 42 notice
The premium is based on the flat's value and lease length on this date, even if the sale and the extension take months to complete.
-
You sell the flat
Agree with the buyer, as part of the sale, who pays which costs.
-
Your solicitor transfers the claim at completion
The buyer takes over your notice. Passing it on does not itself extend the lease.
-
The buyer agrees and pays the premium
The legal deadlines from your notice keep running.
-
Lease extended by 90 years
Ground rent reduced to nothing.
What to check before choosing
For either route, a mortgage buyer must check their lender's requirements. Passing on a notice does not itself extend the lease. If the existing lease is unacceptable to the lender, the extension may need to finish before or alongside the purchase.
Use a solicitor and valuer with lease extension experience, and get quotes before serving notice. If the claim is withdrawn, or lapses because a deadline is missed, whoever holds the notice at that point owes their own advisers' fees and the freeholder's reasonable legal and valuation costs up to then.
6. How Much Does a Lease Extension Cost?
A statutory lease extension in England and Wales has two main costs: the premium, which you pay to the freeholder, and the legal and valuation fees.
The premium
The premium is calculated under the rules in the 1993 Act. It depends on:
- How many years remain on the lease.
- The flat's value before and after the extension.
- The ground rent and any future increases.
- The valuation rates used to calculate the freeholder's lost rent and the cost of waiting longer to take the property back.
If the lease has 80 years or fewer remaining when the formal notice is served, marriage value also applies. This is an additional payment linked to the increase in value created by extending the lease.
The 80-year cliff: the cost to extend jumps
What it might cost to extend the lease on a flat worth about £300,000, at each point in the lease. The cost rises slowly while the lease is above 80 years. Once it drops below 80, the cost jumps.
Years left on the lease
- Above 80 years: no marriage value
- Below 80 years: marriage value added
The cost can vary considerably, even between flats worth the same amount. The Leasehold Advisory Service's free lease extension calculator gives an initial estimate for flats with at least 40 years left. For a professional valuation, use a surveyor who specialises in lease extensions.
Professional fees
Under the current rules, you generally pay:
- Your solicitor, to handle the legal work.
- Your surveyor, to value the extension and help negotiate the premium.
- The freeholder's reasonable legal and valuation costs.
You also need to allow for registration fees and other expenses. A dispute can add to the cost. Ask for itemised quotes showing VAT, what is included and any possible extra charges.
What could change under the 2024 Act?
The Leasehold and Freehold Reform Act 2024 includes changes intended to make extensions cheaper and simpler. These include:
- Abolishing marriage value.
- Allowing leaseholders to add 990 years to their lease.
- Capping the ground rent used to calculate the premium.
- Introducing government-set valuation rates.
- Generally removing the requirement to pay the freeholder's legal and valuation costs.
As of September 2026, these changes have not taken effect. Further legislation is needed, and there is no confirmed start date.
The reforms could reduce your costs, particularly if you have a short lease. For now, base your budget on the current rules. The House of Commons Library tracks progress.
7. Can You Get a Mortgage on a Flat With a Short Lease?
Yes, but it depends on the lender and the lease. A short lease can make borrowing harder and affect how much a buyer can borrow.
What lenders check
Lenders consider:
- How many years remain on the lease when the mortgage starts.
- How many years will remain when the mortgage ends.
- The size of the buyer's deposit.
- The lease terms, the flat's value and how easily it could be sold.
Each lender sets its own limits. For example, Nationwide's published rules for existing properties in England and Wales require at least 55 years remaining at application and 30 years after the mortgage ends. If the buyer borrows more than 85% of the property's value, Nationwide requires at least 90 years at application. Approval also depends on the valuation.
How the mortgage term affects the decision
Suppose a lender requires 30 years to remain on the lease after the mortgage ends:
- A 25-year mortgage would need at least 55 years left at the start.
- A 35-year mortgage would need at least 65 years left at the start.
The flat must also meet any separate minimum lease length and the lender's other requirements.
Who can still buy at each lease length
A rough guide to which buyers can go ahead as the lease gets shorter. Cash buyers can proceed at any length. Anyone who needs a mortgage depends on their lender.
| Type of buyer | 90+ years | 80-89 | 70-79 | 60-69 | Under 60 |
|---|---|---|---|---|---|
| First-time buyer with a small deposit | Yes | Some | No | No | No |
| Home buyer with a standard mortgage | Yes | Yes | Some | No | No |
| Buy-to-let landlord with a mortgage | Yes | Yes | Some | Some | No |
| Cash buyer or investor | Yes | Yes | Yes | Yes | Yes |
| Auction bidder | Yes | Yes | Yes | Yes | Yes |
What this means if you are selling
A short lease can reduce the number of buyers able to get a mortgage. It can also lead to a lower valuation, reducing how much a buyer can borrow or causing the lender to decline the property.
Buyers should check the lease with their lender or mortgage broker early. This helps establish whether they can finance the purchase and whether the lease needs extending before completion.
8. Will a Short Lease Put Off Buyers?
Yes, some buyers. A short lease can make it harder to get a mortgage, and buyers may be concerned about the cost and work involved in extending it.
Who might be put off?
- Buyers who need a mortgage. The lease may not meet their lender's requirements. Buyers with small deposits can face stricter rules on lease length.
- Buyers with little spare cash. Paying for an extension and professional fees on top of the purchase may stretch their budget. The extension cost depends on the flat and its lease.
- Buyers who want less work. Some may prefer a flat where they do not need to organise a lease extension.
Who might still buy?
Potential buyers include investors, cash buyers and people who want to live in the flat. Buyers using a mortgage will need the lease to meet their lender's requirements, or an extension arranged as part of the purchase.
A buyer may factor the cost and effort of extending the lease into their offer.
Tip: Be clear about the remaining lease length in your advert and have a professional estimate of the extension cost available. An agent experienced in short lease sales can help you assess whether a standard listing, an auction or marketing to investors would suit your flat.
Question 10 below describes the investor and cash buyer groups in more detail.
9. How Should I Price a Short Lease Flat?
Start with what the flat would be worth with a long lease, then consider the extension costs and recent sales of similar properties.
How a buyer might calculate their offer
An investor may deduct the extension costs from the flat's long-lease value, then allow for other expenses, time, risk and profit.
Possible offer = long-lease value - extension premium - professional fees - allowance for other costs and profit.
This helps explain an investor's offer. Buyers planning to live in the flat may take a different approach.
Worked example
Take a flat with 72 years left on its lease. With a long lease it would be worth £350,000. Each orange bar is a cost the buyer takes off that £350,000. The green bar is what is left, which is the buyer's offer.
The £35,000 allowance is 10% of the long-lease value. That percentage is used for this example only; it is not a standard investor margin.
The £25,000 premium also depends on the actual flat. Lease length and property value alone are not enough to calculate it: ground rent and other valuation assumptions matter too.
Common pricing mistakes
- Ignoring the short lease. Comparing your flat with long-lease properties without adjusting for the difference can overstate its value.
- Guessing the extension cost. Get a specialist valuation and fee quotes, including the freeholder's reasonable legal and valuation costs.
- Treating one investor's calculation as the market value. Different buyers have different costs, budgets and expectations.
- Setting a high price without evidence. Leave room to negotiate, but make sure recent comparable sales support your asking price.
Setting the asking price
Ask three agents with short lease experience for an estimated sale price and a suggested asking price. Ask them to explain their figures using recent comparable sales.
Use those valuations alongside the extension estimate to decide your asking price and how much room to leave for negotiation.
10. Who Buys Short Lease Properties?
Most buyers of short lease flats are investors or cash buyers rather than people looking for a home to live in. Each group has different reasons for buying and different limits on price, so it pays to know who you are selling to.
Cash buyers
Private cash buyers and specialist cash-buying companies are usually the most reliable buyers for a short lease flat. They need no lender's approval, they are used to the legal complications and they price the discount in from the start. Completion typically takes 3 to 6 weeks. The trade-off is price: cash buyers typically offer 15 to 30 percent below open-market value, sometimes more for a very short lease. Sell Flat UK is one such buyer; other reputable specialist firms work in a similar way.
Buy-to-let landlords
Landlords work out the rental yield (the yearly rent as a percentage of the price) with the extension cost included. Where the rent is strong enough, a short lease flat can suit a landlord who plans to extend later. Some use specialist short lease mortgages, though these are scarcer and dearer than standard buy-to-let loans.
Investors who refurbish
Many short lease flats also need work, and investors often combine the two: buy at a discount, refurbish, extend the lease, then sell at the higher price or keep the flat to let. The extension is simply one known cost in the project budget.
Developers
A developer may buy short lease flats as part of a bigger plan, such as buying several flats in one block to extend them together, or as part of a redevelopment. This is rarer for a single flat, but worth considering where the building suits it.
Specialist short lease buyers
A small but active group of investors buy short lease flats, extend them and sell them on at the higher price. They work with lease extension surveyors and solicitors all the time and can move quickly. They tend to concentrate on London and other high-value areas, where marriage value makes the biggest difference.
Auction buyers
Auction is a natural route for a short lease flat, because the people who bid at auction are largely the same groups listed above. A traditional unconditional auction can give a good balance of speed, certainty and price, particularly where the lease is below 70 years. See our auction guide.
Buyers you are unlikely to see
- First-time buyers and anyone borrowing a high share of the price, because lenders' rules exclude them.
- Owner-occupiers who cannot afford an extension on top of the purchase price.
- People who want a long-term home without leasehold paperwork.
Tip: market to investors directly. Rightmove and Zoopla reach the public, but the offers on a short lease flat tend to come from a small part of that public. Auction houses, investor mailing lists, property investment forums and agents who specialise in short leases reach the right people faster.

Further FAQs
There are three ways. The Leasehold Advisory Service's free online tool uses HM Land Registry data and gives the years, months and days left in about two minutes. The title register from HM Land Registry costs £7 and shows the lease start date and term; it is the document a buyer's solicitor will check. Or read your own copy of the lease, which states the term and the date it runs from.
Our guide to checking how many years are left on your lease walks through each route.
Yes. An informal extension is a private deal on whatever terms you both accept. It can be quicker and cheaper, but you have no right to it: the freeholder can refuse or name their price, and the new lease may keep or even raise the ground rent.
The formal route under the 1993 Act adds 90 years, cuts the ground rent to nothing and lets a tribunal fix the price if you cannot agree. Buyers' lenders usually prefer a lease on those terms, so check what a buyer's lender will accept before you agree an informal deal. See statutory versus informal lease extensions.
You can still extend. If you have made reasonable efforts to trace the freeholder, you can apply to the county court for a vesting order under section 50 of the 1993 Act. The court grants the extension, a tribunal sets the premium and you pay it into court. It takes longer and costs more than a normal claim, and you need evidence of your search.
A missing freeholder also slows a sale, because the buyer's solicitor cannot get the usual replies. See our guide to selling a flat with a missing freeholder.
Yes, and auction suits short leases well. The bidders are mostly investors and cash buyers who already price the extension into their offers. At a traditional unconditional auction the sale is binding when the hammer falls, and the buyer usually completes within 28 days. You set a reserve, the lowest price you will accept, and the auctioneer's commission is typically 2 to 3 percent plus VAT. See our auction guide.
Not directly. The service charge depends on the building's running costs, not the length of the lease. The ground rent carries on as the lease says until the lease is extended; a formal extension under the 1993 Act reduces it to nothing.
Ground rent matters to buyers in its own right. A rent that doubles or rises with inflation can put lenders off even on a long lease. See ground rent explained.
Possibly, but nobody knows when. The changes in the Leasehold and Freehold Reform Act 2024 that would cut extension costs are not yet in force, and as of September 2026 there is no start date (see question 6 above). Meanwhile your lease gets shorter every month, and once it reaches 80 years or fewer marriage value adds to the cost.
Waiting is a bet on timing. Many sellers instead extend now, or sell to a buyer who prices the lease as it stands.
