How to use this

Run the math three ways before signing anything: (1) the loan amount you actually need (build a 12-month cash flow first), (2) a stress test 25% above that amount in case revenue is slower than expected, and (3) the same amount at a 2-point higher rate to see what a market shift would do to your payment. If any of those scenarios would force you to default, the loan is too aggressive.
