Most lenders are interested in how long you've been at a certain job or lived in the same location, and whether you have a record of finishing what you start. If your past record doesn't show a history of stability, then be prepared with good explanations. Not only is the amount of income you earn important but so is your ability to live within that income. Some people earn $100,000 a year and still can't pay their debts, while others budget nicely on $20,000 a year.
Small businesses have a tougher time getting approved due to factors including lower sales volume and cash reserves; add to that bad personal credit or no collateral (such as real estate to secure a loan), and many small-business owners come up empty-handed. Getting funded takes longer than other options — typically two to six months — but banks are usually your lowest-APR option.
