Will there be any maintenance?
A lot of modern houses are described as ‘low maintenance’, but this does not mean ‘no maintenance’. There is no such thing as a maintenance-free house.
Check that you will have easy access to areas of your house that need regular maintenance, like gutters. Also check that landscaping features will not present problems (for example wall claddings that are likely to come into contact with the ground or garden debris).
Remember, fibre-cement cladding or other speciality exterior cladding will usually need more and professional maintenance than a weatherboard house.
