Structural & Safety
Roofing defects, subsidence, unstable walls or failed wall ties can make standard lenders decline an application.
01
Why properties become unmortgageable
Mainstream mortgage lenders need a property to meet their security and habitability standards from day one. These are the most common barriers—and the opportunity for well-prepared investors.
Habitability
A missing kitchen or bathroom, severe damp, or a property requiring full rewiring may be deemed unfit to occupy.
Property Condition
Dry rot, Japanese knotweed and serious dereliction often require specialist works before a mortgage is possible.
Legal & Construction
Short leases below 80 years, absent planning consent, or non-standard construction can fall outside mainstream criteria.
