I looked at the buy then build book on acquisition entrepreneurship. The author loves SBA loans. Your situation is almost swingable with a zero percent credit card, a little bit of cash, and seller financing--i.e. you take out a $25K cash advance on credit card, and pay the seller the rest out of earnings over 1-2 years. Also the 401K penalty is 10%, which is not the end of the world if you really want to do this. Take out $25K and the penalty is 2500 (and you pay taxes), but if that gets into the biz, and jumps your income a huge percentage, it may make sense. I would absolutely not pay the 250K in cash, there should be some owner financing portion, or loan, ideally non-recourse.
