Truck Driver House Funds

Im a truck driver that is trying to build a house out of pocket without any banks. I have already bought my land and im in the last stages of my land development. My blueprint is done and soon i will be laying my foundation so that i can start the building process.
This is not easy because im doing everything out of pocket basically check to check. I refuse to have a 30 year mortgage because i dont know what's going to happen in the next few years. The outbreak brought my truck driving job to a halt as it did many people,but im determined to work hard and stay focused to complete my goal. I am still Trucking
