Many people prefer to buy a new home, newly built. Typically as they can move straight in, there is no chain, they have no DIY work to do, the fixtures and fittings are brand new and in addition the house is probably cheaper to run and more environmentally friendly.
In addition over 85% of new homes built in the UK should come with the National House building Council (NHBC) warranty.
One of the best websites is Smart new homes
The other very good new homes website is the New homes marketing board website. It has over 150,000 properties listed and all sorts of good advice.
