To qualify for an unsecured business loan you must have been in business for at least 6 months and have a reasonably clean credit history. Clearly cash flow and profitability are a consideration for an unsecured loan but these requirements are generally much lower than people expect.
To qualify for a secured business loan you have to have an unencumbered asset and a means of servicing the loan. When applying for a secured business loan it is less important to demonstrate an ability to service the loan from past performance but to demonstrate a plan to servicing the loan going forward.
