1. What is a Short Lease?

A “short lease” generally refers to a leasehold property with less than 80 years remaining on its lease. In some markets, buyers start to worry as early as 90 years—but 80 years is the critical point where significant value erosion begins.

Unlike freehold properties, leasehold ownership is temporary—you own the right to live in the property for the duration of the lease, after which it reverts to the freeholder.


2. Why Lease Length Matters

Lease length affects more than just your resale value—it impacts:

  • Mortgage eligibility
  • Buyer confidence
  • Legal risk exposure
  • Future extension costs
  • Saleability timelines

A flat with 78 years on the lease may be significantly less attractive than one with 82 years, even if both are otherwise identical.


3. The 80-Year Rule Explained

Once a lease drops below 80 years, the cost to extend it rises dramatically. This is because of “marriage value”, a legal concept requiring leaseholders to share the property’s future value increase with the freeholder when extending.

Above 80 years? You don’t pay marriage value.
Below 80 years? You do. That difference can add tens of thousands to your lease extension bill.


4. How Lease Length Affects Value

Estate agents and surveyors often apply a direct discount to property value based on the lease term. Example:

  • 95+ years remaining – full market value
  • 85–89 years – minor reduction (~5%)
  • 70–79 years – moderate reduction (10–20%)
  • Under 70 years – severe reduction (25–35% or more)

This means a £300,000 flat with a 68-year lease might only fetch £210,000–£230,000 on the open market.


5. Why Buyers Avoid Short Leases

Even when priced lower, short-lease flats struggle to sell. Why?

  • Mortgage lenders often refuse to lend
  • Buyers fear high future costs
  • It’s harder to remortgage later
  • They worry about lease extensions
  • Resale value is uncertain

This narrows your pool of potential buyers dramatically.


6. Can You Sell Without Extending?

Yes—but it’s all about strategy. Many sellers opt not to extend, particularly if:

  • You need to sell quickly
  • You lack the funds for an extension
  • The buyer is cash-only or an investor
  • The property is unoccupied or inherited

That’s where cash buyers like SellTo come in—we specialise in these niche cases.


7. How Much Does a Lease Extension Cost?

Lease extension costs vary based on:

  • Property value
  • Lease length
  • Ground rent
  • Location

2025 Estimates (UK average):

Lease LengthEstimated Cost (Incl. Fees)
79–85 years£6,000 – £9,000
70–79 years£10,000 – £18,000
Under 70 yrs£18,000 – £40,000+

These are just estimates. Always get a professional valuation.


8. Do You Qualify to Extend the Lease?

You usually need to have owned the property for at least 2 years to have a statutory right to extend the lease under the Leasehold Reform Act. However:

  • You can assign this right to a buyer
  • Or extend voluntarily through negotiation with the freeholder
  • Investors like SellTo don’t require you to extend first

9. Alternatives to Extending the Lease

  • Sell the flat “as-is” to a buyer like SellTo
  • Assign the right to extend to the buyer
  • Negotiate an informal extension with the freeholder prior to sale
  • Offer a discount in the asking price to reflect lease status

10. Preparing Your Flat for Sale

Even if your lease is short, presentation matters:

  • Declutter thoroughly
  • Deep clean and deodorise
  • Neutral décor is best
  • Repair any minor cosmetic issues
  • Consider professional photos or staging

11. Essential Legal Documents and Paperwork

Get these ready before marketing:

  • Lease agreement (official copy)
  • Service charge and ground rent statements
  • Any section 20 notices
  • Building insurance info
  • Management pack (for buyers’ solicitors)
  • Title deeds (from Land Registry)

12. Setting the Right Asking Price

Price strategically by:

  • Reviewing local sold prices of similar short-lease flats
  • Factoring in cost to extend
  • Considering whether you’re selling to an investor, first-time buyer, or cash buyer
  • Consulting a specialist valuer or buyer like SellTo

13. Finding the Right Buyer for a Short-Lease Flat

Your flat may not appeal to every buyer. Focus on:

  • Cash buyers
  • Developers and investors
  • Lease extension-savvy buyers
  • Buyers with access to bridging loans
  • Specialist property companies like SellTo

14. Should You Sell to a Cash Buyer?

Pros:

  • Faster sales (often in 7–21 days)
  • No mortgage issues
  • Fewer surveys and delays
  • Can sell “as-is”—no need to extend
  • SellTo pays legal costs and handles all admin

Cons:

  • Slightly lower price than open market—but often offset by avoiding fees, holding costs, and delays

16. Leasehold Reform and What It Means for You

The UK government has proposed leasehold reform in recent years, including:

  • Abolishing marriage value
  • Capping ground rent
  • Making extensions easier and cheaper

However, as of 2025, changes are still in flux. Don’t delay your sale waiting on legislation—it may not pass in time to benefit your transaction.


17. Common Buyer Objections and How to Overcome Them

Objection: “The lease is too short.”
Solution: Highlight discount or offer to assign extension rights.

Objection: “We can’t get a mortgage.”
Solution: Focus on cash buyers or SellTo.

Objection: “Too much hassle.”
Solution: Provide all documents upfront. Offer flexible move-out dates.


18. Using a Solicitor Who Understands Leaseholds

  • Specialises in leasehold sales
  • Can liaise with managing agents
  • Understands statutory vs. informal extensions
  • Is responsive to buyers’ legal teams

SellTo works only with experienced leasehold solicitors for smooth completions.
