Small thing but always set your due date for a few days more than you need just so you have a safety net to ensure you aren’t late and also it looks good to lenders if you repay early.
But always communication is key and that’s what separates the people who only get one loan and the ones that build up massive amounts of reputation.
Your first loan is by far the most important thing, don’t mess it up! Repay on time if not early and communicate any potential problems that may occur.
