Coocarooch, first of all....what is a Coocarooch?
For 18 years now I've worked with builders - custom builders, production builders, builders big and small. Since the end of 2000, new home sales is my sole focus. In this 18 year time span, I've helped nearly 1000 families with their new home buying/construction process. Over the years, I've observed that there are some personality types who just shouldn't build a house from the ground up. Its way too stressful for some folks to have to make decisions about things they are having to "see" in their heads.
Some people can totally imagine how things will look without having to physically see the item built first. For example, choosing a plan you've only seen on paper is really tough for most people. 9 times out of 10, buyers will choose the model home plan or at least a plan that is built and can be viewed by walking through it.
Even making design decisions can be stressful for some people. They know what they like when they see it, but really don't enjoy trying to put things together. For example, choosing tile and a design for a kitchen backsplash, and choosing matching cabinets and countertops sends some folks over the edge.
Other personality types want to choose every single detail and spend hours giving thought to every aspect of the house. They thrive on the process. Most of us fall somewhere in between the two extremes.
The building process can be full of surprises, both pleasant and not so pleasant. The key to a successful happy ending is to choose a builder you have researched. If the builder has a reputation for quality and customer service after closing, you will likely have a fine experience.
Remember that every home ever built, in any price range, by any builder, has had some type of error or mistake that needed to be corrected. The unexpected happens on a daily basis - after all, the house will be crafted by human beings. So whatever can happen will. The key is that the builder known for a quality finished product will always make whatever is wrong, right again with minimal fuss and bother to you the customer.
Find a builder you trust, then you will be able to contain anxieties that are bound to surface.
Good luck with your endeavor if you decide to proceed forward. Once you've built a home and had a good experience, you might never want to buy a "used" home again.
