That seems like a simple enough question. Then you start thinking about what you need in a house and what you want in a house. Chances are that you won't find EXACTLY what you want in an existing house, but you may be able to get pretty close. On the other hand if you build a house you can choose everything and get exactly what you want. The only issue with building is that it's very easy to set parameters that are far above and beyond what we would actually be fine with if we chose an existing home. For example, when you are looking at floor plans and the rooms look small on that blueprint, so you have them add a few feet here and a few feet there and next thing you know you have increased the square footage of the home by 300 square feet. So now the 1700 sq ft house you were aiming for is 2000 sq ft, not to mention more expensive. It's easy to keep adding when you are looking at a floor plan on paper. That's why we always suggest looking at house plans that are smaller than your target size, because it is easier to add square footage than take it away and you won't end up blowing your budget. Also, most of the time the larger house plans don't have rooms that are that much bigger, they usually just have MORE rooms. So if you just want more space, start with a smaller house plan and you can add and tweak it without going over the size you wanted.
