I knew a man who was caught for years in a business he hated because he had taken money from friends and family and he didn't have the heart to tell them he'd failed.
On the other hand, it's against the law for a bank to lend you money just because they like your business plan. You must have assets to put at risk, meaning assets you lose if you don't repay the bank. In some cases the Small Business Administration (SBA) will guarantee up to 70 percent of the loan -- ask about that at your bank, the SBA does it using the banks, not directly with you. But even in those cases you still have to put up 30 percent of the funding yourself.
And if you have an investment-worthy business -- meaning it's run by people with real startup experience -- and are offering a good shot at strong market growth, defensibility and scalability, then you might even be better off sharing your business with investors who will put money into the business in exchange for ownership.
I've written a lot about these options on my blog Planning Startups Stories. Look especially at the categories angel investment, bootstrapping, and business financing.
