The selection of the right builder should be based on a host of qualifications. Naturally, you will want to review his resume, portfolio, and visit some of the homes he has recently built. His reputation for honesty and integrity in the building community is important, and go hand in hand with his skills as a builder to produce top quality work with the desired results and at minimum expense and waste.
When interviewing builders, ask about the various forms of contract options that are available to you and how they impact the final cost of your home. Your builder should help you to understand the specifics and the benefits that each option will offer you. As an example, if you are required to put down a deposit, is that deposit invested and earning interest for your benefit?
When you build your dream home, it's important that it is an exciting, pleasurable, rewarding experience. The builder you choose should be someone you not only trust, but someone with whom you are compatible. His willingness and desire to attend to details, to communicate honestly with you and carefully explain each step of the process will go a long way to avert problems down the road. Take the time to interview past clients. Find out about the quality of construction, and especially the level of satisfaction they experienced with his follow up process. When the home was finished, did he respond in a timely and courteous manner to their requests to meet their needs after they moved in?
