After the house design is agreed upon, we will create a contract for you. The contract specifies what materials are to be used, what comes with the house (based on how much or how little you want us to do from a shell to turn key - move in ready), and of course the total cost to build.
The total cost will be typically broken down into about 8 payments called a "draw schedule." You only pay us the amount specified in your draw schedule after that phase of construction is completed.
There are many more parts to the contract that discuss legal terms designed to protect you but really, what most people are really interested in is how much will it cost to build the house they want.
