There are many reasons why your equity release application may be rejected such as:
Flat roof
Near to Commercial Property e.g. Public House or Launderette
Other hazards e.g. motorway, electricity stations, pylons etc
Non-standard construction
Flood risk
Single skin brick
Ex Local Authority property
Asbestos
Spray foam under roof
Unkept/un-maintained property
Cluttered property inside
You should be mindful of reasons why property may be suitable when applying for equity release but also if you are buying a home anyway, look out for reasons which may detract from your ability later to either sell your home or use equity release.
