It usually doesn't matter to mortgage lenders who you are. It's your numbers that count -- specifically, the size of your paycheck and the balance in your savings. But, if you've recently embarked on self-employment or are in a new career where pay is performance-based, lenders will veer a bit from the numbers path. Because of the number of people who have lost their jobs in the last few years, more borrowers fall into those categories. They can get a loan, but it will probably carry a higher interest rate than what's available to those with a steady paycheck or longevity in the same career.
