Many buyers only discover the problem after submitting a mortgage application, receiving a valuation report or reviewing the legal paperwork. In some cases the lender reduces the amount they will lend; in others the application is declined altogether.
At AF Credit, we specialise in helping buyers purchase properties that mainstream lenders struggle to finance — including short lease flats, auction properties and other assets that fall outside conventional mortgage criteria.
Yes, but it depends on the remaining lease term. Most mortgage lenders have minimum lease requirements — the shorter the lease, the fewer lenders are likely to consider the property. Where mainstream lenders decline, bridging finance can complete the purchase while the lease is extended and the property refinanced.
Lease Length and Mortgage Availability
Every lender has different criteria, but remaining lease term is one of the most important factors affecting mortgageability. As a general guide:
| Remaining Lease | Mortgage Availability | Status |
|---|---|---|
| 100+ years | Widely accepted by mainstream lenders | Mortgageable |
| 90+ years | Widely accepted | Mortgageable |
| 80+ years | Generally mortgageable — monitor closely as it approaches 80 | Mortgageable |
| 70–80 years | Some lender restrictions begin to appear | Restricted |
| 60–70 years | Limited mortgage options; specialist lenders required | Difficult |
| 50–60 years | Very few mainstream lenders; bridging commonly used | Very difficult |
| Below 50 years | Often considered unmortgageable by mainstream lenders | Unmortgageable |
What Is a Short Lease Property?
A short lease property is usually a leasehold flat or maisonette where the remaining lease term has fallen below the level preferred by mortgage lenders. Unlike a freehold property, a leasehold property is a wasting asset — the lease term gradually reduces over time. As the lease shortens, mortgage options reduce, property values may fall, lease extension costs increase and buyer demand can decrease.
Why Do Mortgage Lenders Care About Lease Length?
Mortgage lenders use the property as security for their loan. Their concern is whether the property will remain marketable, valuable, mortgageable and attractive to future buyers. If the lease becomes too short, future buyers may struggle to obtain a mortgage — reducing the property's value and increasing the lender's exposure.
Many lenders calculate their minimum lease requirement as the mortgage term plus a buffer — for example, 25 years of mortgage plus 50 years, requiring at least 75 years remaining at the point of application.
The Critical 80-Year Threshold
The 80-year mark is one of the most important milestones in leasehold ownership. Once a lease falls below 80 years, marriage value may become payable when extending the lease. Marriage value is the additional value created by the lease extension, and under current legislation part of this increase may be payable to the freeholder — making extensions progressively more expensive the shorter the lease becomes.
This means that below 80 years, lease extension costs often increase, property values can begin declining more rapidly, and buyers and lenders become more cautious. For this reason, many leaseholders seek to extend before the lease falls below 80 years.
What Happens If a Mortgage Is Declined Due to the Lease?
One of the most common scenarios is a buyer receiving a mortgage decline after the valuation report highlights the lease length. The lender may decline the mortgage, reduce the loan amount, require a lease extension before completion, or refer the case for specialist underwriting.
A mortgage decline does not mean the property cannot be purchased — it means an alternative strategy is required. This is where bridging finance frequently becomes part of the solution.
Does a Short Lease Affect Property Value?
Yes. Generally, the shorter the lease, the lower the property's value. This is because mortgage availability decreases, lease extension costs increase and buyer demand reduces. However, this often creates opportunities for informed buyers who understand how lease extensions work and can access specialist finance.
The Lease Extension Opportunity
In many cases, leaseholders are entitled to extend their lease under the Leasehold Reform Act. A successful lease extension can significantly improve the property's value, mortgageability, saleability and buyer demand. Many investors use short-term bridging finance to purchase the property, then complete the lease extension process before refinancing onto a conventional mortgage at a significantly higher value.
The Short Lease Strategy: Buy Low, Extend, Refinance High
For experienced investors, short lease properties can represent one of the most consistent value-add opportunities in the residential market. The gap between short-lease and extended-lease value is often substantial — and the extension process, while not straightforward, is well-established and legally protected.
Bridging Loans for Short Lease Properties
Bridging finance can provide a practical solution where a mortgage has been declined, the lease requires extension, the property is being purchased at auction, or a refinance is planned after the lease extension is completed.
Unlike traditional mortgage lenders, bridging lenders focus on the property's value, the lease extension strategy, the borrower's experience and the exit plan — allowing buyers to acquire properties that many conventional purchasers cannot finance.
How AF Credit Can Help
AF Credit specialises in financing properties that mainstream lenders decline. We regularly assist buyers purchasing short lease flats, leasehold investments requiring lease extensions and mortgage-restricted properties. Where a clear strategy exists to extend the lease and refinance, we can often provide bridging finance to facilitate the purchase.
Details of the remaining lease term and purchase price, a clear lease extension strategy, an independent valuation, the proposed exit route — refinancing once the lease is extended — and supporting legal information where appropriate.
Using a Bridging Loan to Purchase and Extend
The buyer identifies a short lease property and agrees a price — often at a meaningful discount to its extended-lease value. A specialist solicitor confirms the lease extension eligibility and likely premium.
AF Credit reviews the purchase, existing lease term, likely post-extension value and exit strategy. We can consider residential bridging where the transaction stacks up and the exit is clear.
The bridging loan funds the acquisition. Once the buyer has owned the property for two years, they have a statutory right to extend under the Leasehold Reform Act.
A leasehold valuation tribunal specialist or solicitor serves the Section 42 notice and negotiates or litigates the premium. The extension is completed, adding 90 years to the existing term and reducing ground rent to a peppercorn.
With the lease extended, the property becomes mortgageable again. A conventional mortgage is arranged at the post-extension valuation — the bridge is repaid and equity created through the process.
Example
A buyer agrees to purchase a flat for £250,000. The lease has only 58 years remaining. The mortgage lender declines the application because the lease falls below its minimum criteria.
AF Credit provides bridging finance, allowing the purchase to complete. The buyer's solicitor advises that the extended-lease value of the flat would be approximately £310,000.
After two years of ownership, the buyer serves a Section 42 notice and extends the lease to over 150 years. The property is subsequently refinanced onto a conventional mortgage at the post-extension valuation — repaying the bridge and creating substantial equity from the transaction.
Frequently Asked Questions
What is considered a short lease?
Generally, leases below 80 years begin attracting increased scrutiny from lenders and buyers. The 80-year mark is a significant threshold because once a lease falls below it, marriage value may become payable when extending — increasing the cost of the extension. Many lenders begin applying restrictions at 85 years to ensure the lease remains above 70 years at the end of a standard mortgage term.
Can you get a mortgage on a 70-year lease?
Often yes, although lender choice is reduced. Many mainstream lenders will still consider a property with approximately 70 years remaining, but some apply additional requirements or higher deposit thresholds. The valuation report becomes increasingly important at this lease length.
Can you get a mortgage on a 60-year lease?
Some lenders may consider it, but options become significantly more limited. Specialist lenders may still be available, and bridging finance is commonly used to complete the purchase while the lease extension is progressed.
Can you get a mortgage on a 50-year lease?
Many mainstream lenders will decline at 50 years, making bridging finance or specialist lending more common. This is also where significant investment opportunities arise — short lease properties often sell well below their extended-lease value. See our unmortgageable property guide for more context.
Does a short lease reduce property value?
Yes. As the lease shortens, mortgage availability decreases and lease extension costs often increase — both of which put downward pressure on value. However, once the lease is extended the property typically recovers much or all of the discount, creating equity for the buyer.
Can I buy a short lease property at auction?
Yes. Short lease properties are frequently sold at auction because many buyers cannot obtain traditional mortgage finance within the 28-day completion window. Bridging finance is one of the most common funding solutions — it can be arranged quickly and repaid once the lease is extended and the property refinanced.
