Understanding the Challenge: Flats with Short Leases and Non-Standard Security
Flats with short leases often fall outside the comfort zone of mainstream mortgage lenders. Typically, Discover more these lenders require a minimum lease term remaining (often 70-85 years) to offer their full mortgage products. When lease terms drop below that threshold, a flat may become unmortgageable—though it may still have value for buyers prepared to refurbish, auction buyers, or investors.
Why the hesitation? The shorter the lease, the lower the property's valuation. The resale market narrows since many buyers find financing difficult, leading traditional lenders to assign higher risk or refuse mortgages entirely.
This is exactly where specialist bridging lenders can step in. Bridging loans based on non-standard security can unlock opportunities for these properties. However, this type of lending carries unique challenges and considerations.
What Is a Bridging Loan—and Why Choose It for Short Lease Flats?
A bridging loan is a short-term finance facility designed to “bridge” the gap between purchasing a property and securing long-term financing or completing refurbishment and resale.

- Typical bridging loan sizes range widely: from GBP 50,000 on smaller flats to over GBP 30 million for development projects and portfolio acquisitions. They operate on short terms, usually 3–12 months, making speed and execution critical. Bridging loans are commonly used for auctions, chain breaks, refurbishments, or when immediate purchase completion is necessary.
For flats with short leases, bridging loans can provide fast access to capital, enabling buyers to secure the property before lease extensions, refurbishment, or resale is completed. This is especially valuable when time constraints or auction deadlines loom.
Will Lenders Touch Short Lease Bridging Loans? – What to Expect
Many specialist lenders understand the market dynamics of unmortgageable flat bridging and the underpinning non-standard security involved. However, the lending criteria can be more restrictive than standard bridging loans.
Common Lending Criteria Include:
Minimum lease length: While mainstream lenders demand 70+ years, some bridging lenders accept leases as short as 30 to 40 years, especially when backed by strong exit strategies. Exit strategy clarity: Bridging lenders insist on well-defined plans such as lease extension, refurbishment and resale, or remortgage upon completion. Loan to value (LTV): LTVs tend to be lower, often capped at 60% or less of the current property value, given the enhanced risk. Security enhancements: Lenders may require additional security or guarantees. Borrower experience and financial strength: Demonstrated expertise in property refurbishments or lease extensions helps.Bear in mind that bridging lenders’ appetite varies. Leading providers like KIS Finance focus heavily on execution speed and tailored solutions, even if the headline rate is slightly higher than typical mortgages.
Popular Use Cases: Why Borrowers Opt for Short Lease Bridging Loans
Here are some common scenarios where bridging finance shines:
1. Auction Purchases
Auction properties often require rapid settlement—commonly within 28 days. Traditional mortgage offers may take longer to secure, especially for short lease flats, making bridging loans the default option.
2. Chain Breaks
When a chain breaks during a property transaction, speed is essential to prevent losing the deal. Bridging loans allow buyers willing to move quickly to secure or refinance the property.
3. Refurbishments and Lease Extensions
Many investors purchase short lease flats, use bridging finance for refurbishment and lease extension, then either refinance with a mainstream mortgage or sell at a profit. The short-term and flexible nature of bridging loans fits this strategy perfectly.

Fees: Arrangement fees generally range from 1% to 3% of the loan amount. Repayment: Interest-only until the loan expiry, with capital repaid at term end.
Exit Strategies
Planning the exit strategy upfront is crucial to bridging loan success, particularly for short lease bridging loans:

Refurbish and Refinance: Complete necessary renovations to increase property value, then refinance with a residential mortgage. Resale at Auction or Private Sale: Exit via selling the property, ideally at an enhanced valuation.
