Leasehold
How to Sell a House With a Short Lease Remaining
A lease with under roughly 80 years remaining makes a leasehold property hard to mortgage and sell, and once it drops below 80 years the cost of extending rises sharply because of "marriage value". Your options: extend the lease before selling (best price, but it takes time and money), sell as-is at a reduced price to a cash buyer or investor, or start the statutory extension and assign the benefit to your buyer. The right choice depends on how short the lease is and how quickly you need to sell.

Extend the lease first, or sell as-is?
Five quick questions on your lease and timescale — then a clear recommendation and the safe way to act.
How many years are left on the lease?
Have you owned it two years (to extend)?
How soon must you sell?
Appetite for the cost and wait of extending?
What matters most?
Selling as-is to a cash buyer or investor is your cleanest route.
With a short lease, limited time, or no appetite for a slow, costly extension, a cash buyer or investor who extends the lease themselves is the fast way out — completing in 7–28 days. Compare several vetted offers so they compete.

If the lease is near 80 years, you are eligible, and you can wait, extending makes the flat readily mortgageable and widens the market — usually the highest price. Keep a vetted cash sale in reserve. A free valuation frames it.

A lease is a wasting asset — the fewer years remaining, the less the property is worth and the warier lenders become. Most lenders want a minimum unexpired term (often 70-85 years at the end of the mortgage), so a short lease shrinks the buyer pool to cash purchasers. Below 80 years, "marriage value" kicks in: the freeholder is entitled to a share of the uplift in value from extending, making the extension significantly more expensive. That 80-year threshold is the single most important number in short-lease selling.
Extending before you sell
If you have owned the flat for at least two years you generally have a statutory right to extend by 90 years at a peppercorn ground rent under the Leasehold Reform, Housing and Urban Development Act 1993. Extending first usually gets you the best sale price and the widest market, because the flat becomes readily mortgageable. The downside is cost and time — valuation, legal fees, the premium to the freeholder, and several months of process — so it suits sellers who can wait and want maximum value. The closer the lease is to 80 years, the more urgent it is to start.
The faster routes
| Route | Speed | Price | Best when |
|---|---|---|---|
| Extend, then sell | Slow (months) | Highest | You can wait, lease near 80 years |
| Assign started extension to buyer | Medium | Good | You want to widen the market without finishing |
| Sell as-is to cash buyer/investor | Fast (7-28 days) | Lower | You need certainty and speed |
Cash buyers and investors buy short-lease flats routinely and extend themselves.
How "marriage value" works
Marriage value is the increase in the flat’s value created by extending the lease, which the law says is shared between leaseholder and freeholder once the lease falls below 80 years. Above 80 years, no marriage value is payable, so the extension premium is far lower. This is why advice is consistent: if your lease is approaching 80 years, extend (or at least serve notice) before it crosses that line, because the cost can jump substantially the day it does. A surveyor specialising in lease extensions can calculate the premium for you.
Selling a short-lease flat fast
If you cannot wait, you can sell the flat with the short lease as-is, accepting a lower price; cash buyers and investors buy these routinely and extend themselves. Alternatively, serve notice to start the statutory extension and then assign the benefit of that notice to your buyer at completion, so they complete the extension — this can widen your market without you finishing the process. A cash sale completes in weeks and removes the uncertainty of waiting on a lease extension before you can move on. See also ground rent and selling leasehold.

Frequently asked questions
Straight answers, no sales talk
Can I sell a flat with a short lease?
Yes, but a lease under about 80 years limits you mainly to cash buyers and investors unless you extend first. Extending widens the market and raises the price.
Why is 80 years important for a lease?
Below 80 years, "marriage value" applies, sharply increasing the cost of extending. Extending before the lease drops under 80 years is much cheaper.
How can I sell a short-lease flat quickly?
Sell as-is to a cash buyer or investor who will extend the lease themselves, or serve notice and assign a started statutory extension to your buyer. A cash sale completes in 7-28 days.
How long does a lease extension take?
A statutory extension typically takes several months, involving a valuation, formal notice, negotiation of the premium, and legal work. Start early if your lease is near 80 years.
Do I qualify to extend my lease?
Generally you have a statutory right to a 90-year extension at a peppercorn ground rent after owning the flat for at least two years. A solicitor can confirm your eligibility.
What is marriage value on a lease?
The increase in value created by extending the lease, shared between leaseholder and freeholder once the lease is below 80 years — which is why extending sooner is cheaper.
