There is no cost associated with an interview.  This is a time both the builder and the client take to determine if they have common ground.

One of the first things I recommend a client do - is to determine his purchasing potential.  Regardless of the amount you wish to spend, you should confirm your credit ceiling.  Most lending institutions will guide you through this process for a minimal charge ($250 - $500).  If you need help finding a suitable lender - I can help.  A credit approval will apply to any Builder

The design of your home should cost from $0.75 to $1.25 per sq. ft. (under roof).  This can be done independent of your builder but I recommend you work with a builder during this process.  The builder is very important to assist you in designing a home that is within your budget and free of construction issues.

Construction costs are covered by an Interim Construction Loan.  All draws go through the Client.  Once completed - the Construction Loan is retired by a Permanent Mortgage Loan.  Most Financial Institutions will cover 80 to 90 percent of the construction costs.
