Never, Never, never , never buy houses that have a CFD. Those are filled with over-indebted homerenters whose luck is going to run out tomorrow.
Houses without CFD are filled with super-moneyed homeowners with big fat pensions and no worries. They also have character (especially those with river rock fireplaces). However, by definition, you can not buy those houses, because they will never sell..
(P.S. Don’t take it seriously. Just kidding 🙂 )
