Buying a flat with a short lease is often a strong way to secure a property in a prime location at a significant discount. But the excitement of the purchase is quickly replaced by a flat rejection from a high-street lender.
Most mainstream lenders see a lease under 80 years as a declining asset rather than a home. They close the door on the application without a second thought. That can leave buyers and existing leaseholders in a genuinely difficult position. Whether it is a purchase that cannot proceed or a remortgage that cannot complete, being stuck with a property the high street will not finance is a real problem with a real solution if you know where to look.
The answer is to stop trying to force a specialist deal through standard lending criteria. We specialise in the mechanics of short lease finance and know which lenders actually understand leasehold reform and how to structure a deal that secures your future, not just a mortgage.
The 80-year threshold: why the clock is ticking
In the world of UK property, 80 years is the magic, and often dreaded, number. Once a lease drops below this mark, a legal concept called marriage value kicks in. In simple terms, the cost of extending your lease jumps significantly, sometimes by tens of thousands of pounds, because the law has historically required you to share 50% of the value uplift with the freeholder.
While the Leasehold and Freehold Reform Act 2024 promised to abolish marriage value, large parts of the law are still waiting to be commenced by the government. In 2026, many leaseholders are still operating under the old, more expensive rules. This is why getting a mortgage on a flat under 80 years is so difficult. Lenders are wary that the high cost of extending will eat into the equity they are lending against.
Creative solutions for short lease purchases
If you have found a property with 65 or 70 years left, you do not have to walk away. You just need a different toolkit.
Lending against the extended value
This is where specialist lenders operate differently from the high street. Most brokers will try to get you a loan based on what the property is worth today with its short lease. We work with lenders who will provide a short lease mortgage based on the open market value of the property after the lease has been extended.
Imagine you are buying a flat for £300,000 because of its short lease, but it would be worth £400,000 with a long lease. A specialist lender might give you an LTV based on the £400,000 figure. This effectively reduces the cash deposit you need to find, as the value uplift from the extension covers a significant share of your equity requirement.
Bridging loan for lease extension
Sometimes you need to fix the lease before you can think about a mortgage. A bridging loan lease extension facility allows you to buy the property and pay the freeholder's premium for the extension at the same time. Once the new, longer lease is registered at the Land Registry, we then switch you over to a standard, low-rate mortgage. It is a fast, strategic way to manufacture value.
Options for existing leaseholders and investors
You might not be looking to buy. You might just be looking to survive a lease that is shortening every year.
Specialist residential mortgages: we have access to niche lenders who will consider leases as short as 55 to 60 years for owner-occupiers. You will pay a slightly higher rate, but it gives you the breathing room to wait for further leasehold reforms to take effect.
Buy-to-let on short leases: for investors, a short lease can be a high-yield opportunity. We work with specialist BTL lenders comfortable with shorter terms, provided the rental coverage is strong and the location is desirable.
The Section 42 route: the two-year ownership rule was abolished in 2025. You can now serve a formal notice to extend your lease from day one of owning the property. This has made a significant practical difference for buyers who previously had to wait in limbo while their lease became shorter and more expensive to extend.
Why you need a joined-up team
A short leasehold property finance deal is not just about the money. It is about the legal paperwork. If your solicitor does not understand the difference between a statutory extension and an informal deal with a freeholder, your mortgage could still fall through at the last minute.
Lenders will want to see:
· A formal valuation from an RICS surveyor.
· Confirmation of the ground rent structure, ideally moving to a peppercorn.
· A clear timeline for the extension to be completed.
We do not just find the lender. We coordinate with your solicitors and surveyors to make sure everyone is pulling in the same direction. Too many short lease deals fall over because the left hand does not know what the right hand is doing.
The documentation your lender will demand
Navigating a short leasehold finance application requires more than a good credit score. Lenders in the specialist space are detail-oriented because they are taking on risk that the high street refuses to touch. To get a deal over the line, you need your paperwork ready before you pick up the phone.
The most critical document is a formal valuation from an RICS-qualified surveyor with specific experience in leasehold enfranchisement. It needs to clearly state the current value, the projected cost of the extension and the end value once the lease is extended. Without this three-way breakdown, most specialist lenders will not look at the file.
You will also need a clear statement of the current ground rent. Lenders are increasingly wary of doubling ground rent clauses that can make a property unsellable in future. If your lease contains aggressive rent hikes, we may need to use short lease finance not only to extend the term but also to vary the lease terms to a peppercorn rent. This makes the property far more attractive for a future refinance onto a standard product.
Finally, your solicitor should provide a clear report on the freeholder. Some institutional freeholders are easy to deal with, while private individuals can be slow or difficult to locate. Knowing who is on the other side of the negotiation lets us choose a lender with the right level of patience for your timeline.

Frequently asked questions
Can you get a mortgage on a short lease?
Yes, but you will not find it on the high street. You need a specialist lender who is comfortable with the specific risks of short leasehold property.
What is the shortest lease a lender will accept?
Some specialist partners will consider leases as short as 50 years, although the LTV will usually be lower to account for the risk.
Is it worth buying a property with a short lease?
If you can buy at a discount and have the finance in place to extend the lease quickly, it can be one of the more compelling strategies for investors who understand how to approach it.
Do I have to wait two years to extend my lease?
No. Under the 2025 reforms the two-year ownership requirement was scrapped. You can start the process from the moment you complete on the purchase.
Will the 2024 Act make extensions cheaper?
For most people with leases under 80 years, yes. The abolition of marriage value is designed to save leaseholders thousands, but timing matters and large parts of the law are still being commenced. A specialist broker can help you align the application with the timing of the reforms.
