I see my colleagues have provided you with invaluable information, but have left out one important consideration. In Europe, as well as in most parts of the world, brick, as wells as various types of cinder block, provides fantastic insulation and is impervious to damage. It creates a pleasant atmosphere, controls temperature fluctuations and helps conserve energy. Most savvy homebuyers are willing to pay a bit more for a brick facade. Of course a solid brick/cinderblock wall is even more efficient---and costly. Having but one facade surfaced with brick will not significantly result in energy savings. All four walls would have to be so surfaced. One more factor: the brick facade is virtually maintenance free. An occasional powerwashing every few years suffices. Vinyl is an artificial material, but last well over time. Those sandwiched with additional insulation can provide a major energy cost savings.
Good luck in your home purchase,
