Around 1.5 million properties in the United Kingdom, accounting for 6% of the entire housing stock, are deemed too high-risk for standard mortgage lending by major lenders. This emerges from recent analyses, which highlight the challenges in financing certain property types in the British market.
Properties affected by this classification include, among others, thatched cottages, high-rise flats, and houses that lack fully functional facilities. These properties do not meet traditional lending criteria, making their sale and acquisition difficult for potential buyers.
Reasons for classification as unmortgageable
The reasons for the rejection of a standard mortgage are varied. For thatched houses, increased fire risks and associated higher insurance costs can be decisive. High-rise flats, on the other hand, are often associated with concerns about fire safety and the costs of remedying potential defects, such as those that came into focus after the Grenfell tragedy. Properties with missing or inadequate facilities may not meet the criteria for a minimum standard of living assessment.
This situation creates a bottleneck for owners of such properties seeking a sale, as well as for buyers interested in these specific property types. Specialised financing solutions could provide a remedy here, but are often associated with higher interest rates or stricter conditions.
Impact on the property market
The consequences of these widespread rejections affect not only the owners and prospective buyers concerned, but also the broader property market. They can lead to a devaluation of these specific property segments and reduce liquidity in these market areas. Analysts point out that the development can also have an impact on urban development and the renovation of ageing stock, as investments are hampered by restricted financing options.
- —Thatched cottages: Often higher insurance costs and fire safety concerns.
- —High-rise flats: Concerns regarding fire safety and potential remediation costs.
- —Properties without full amenities: Do not meet minimum standards for living quality.
- —Structural defects: can impair the value and thus the mortgageability.
