This is a tough question to give an exact answer to. In my area of the country, the cost per square foot of Fiber Cement falls between Vinyl Siding and Brick Veneer. Brick Veneer is going to last the longest and be less likely to need any sort of maintenance but that comes with the premium cost. Even if you have a budget that can afford your home to be covered in brick, odds are you still will need some area's accented in siding such as dormer's, gables, chimneys, and various other cantilever's on your home's exterior.
This brings you to the question of what type of siding do I use. Vinyl, Fiber Cement, or some other sort material like wood. Vinyl siding is cheap and if installed correctly, gives you the best value for your dollar. Fiber Cement siding costs over twice as much, requires a little more maintenance, but offer's a much better curb appeal.
