Way fewer than you think.  Contrary to what some think,I how I thought when I was younger, banker's really do want to loan you money.  If you have working capital and equity and your banker only wants to loan you money on a positive cash flow then you need to look for a new bank before your banker cuts you off.  In this line of business there are going to be years when it doesn't work on paper. Sometimes those predictions come true and you burn up some working capital and equity. Other times they turn out better than expected and you either maintain working capital and build equity or build both.  The ones that don't have their operating lines renewed will be the ones that don't have working capital or equity they can tap into for extra cash.
