There are different ways to finance private commercial construction projects. A lot of construction projects involve some type of SBA loan. However, it greatly depends on what you are financing, your credit score, and if there are any assets for collateral. I would recommend checking with your preferred commercial lenders like Central Bank, Great Southern, Oak Star, Simmons, SFC, etc. They should be able to direct you to help or you can discuss your options with an SBA representative.
