Flying Freeholds: Why Some Lenders Refuse to Mortgage Them

What a flying freehold actually is

Most freehold properties sit entirely on their own land, with no physical overlap with a neighbour's structure. A flying freehold breaks this pattern: part of the property — commonly an upper floor, a room, or a section of roof — physically overhangs or is supported by land or a building owned by someone else, most often a neighbour.

The classic example is a row of converted period terraces where a bedroom above a shared passageway or archway belongs to one house, while the ground beneath and the passageway itself belongs to the neighbouring property. Similar arrangements arise where houses have been split or extended in ways that create structural interdependence across a title boundary.

Why this worries lenders specifically

This creates a genuine, practical risk: if the structure supporting your flying freehold section falls into disrepair, and the neighbouring freeholder who owns the supporting land has no legal obligation to fix it (and no obligation to let you access it to fix it yourself), you could be left with a deteriorating or even unsafe part of your own property with no straightforward legal remedy.

Lenders, whose security is the property itself, see this as a long-term risk to both structural integrity and resale value — hence the caution.

How lenders typically respond

The exact percentage thresholds and appetite vary meaningfully between lenders, which is why a specialist broker familiar with flying freehold cases can be valuable — a decline from one lender doesn't mean every lender will refuse.

Reciprocal covenants: the key legal protection

The single most important factor in whether a flying freehold is a manageable issue or a serious problem is whether the property's title includes proper, legally enforceable reciprocal covenants — mutual obligations between the affected freeholders covering:

• Support — an obligation not to remove or weaken structures providing support
• Repair — an obligation to keep the shared/supporting structure in reasonable repair
• Access — a right for each party to enter the other's land where necessary to carry out repairs

Where these covenants exist and are properly drafted, much of the lender's underlying concern is addressed, since both parties have clear, enforceable legal duties.

Flying freehold indemnity insurance

Where the title doesn't contain adequate covenants — which is common, particularly in older properties converted decades ago without anticipating modern conveyancing standards — lenders will often require flying freehold indemnity insurance as a condition of approval.

This is a one-off premium, paid at the point of purchase, that protects the buyer (and by extension the lender's security) against the financial consequences of a dispute or defect arising from the lack of formal reciprocal arrangements. It doesn't create the missing legal rights themselves, but it provides a financial backstop if problems do arise.

What buyers should do

1. Ask early — your estate agent or seller should disclose a known flying freehold, but always ask directly and check the title plan yourself via your conveyancer.
2. Get your conveyancer to review the title thoroughly for existing reciprocal covenants, before you're committed to the purchase.
3. Check with your mortgage broker early which lenders are comfortable with the specific proportion and documentation of your flying freehold — don't assume your first-choice lender will accept it.
4. Budget for indemnity insurance if required — typically a modest one-off cost relative to the property price, but a real additional expense to factor into your budget.

Impact on future resale

Because not every lender takes the same view, a flying freehold can narrow the pool of buyers able to secure a mortgage on the property when you eventually come to sell — some buyers' preferred lenders may decline where yours accepted it. This is worth bearing in mind as a long-term consideration, even if it doesn't prevent your own purchase from proceeding.

Bottom line

Flying freeholds are a well-understood, manageable feature of many older and converted properties, but they introduce a genuine legal gap — the absence of automatic mutual support, repair and access obligations that leasehold titles normally include. Whether your mortgage application proceeds smoothly depends heavily on the proportion of the property affected, whether proper reciprocal covenants already exist, and your chosen lender's specific appetite — a good conveyancer and a broker experienced with flying freeholds are essential to navigating this smoothly.
