The answers you give to these four questions will tell you. Lenders want to know that you will have the ability to pay back a mortgage loan. One factor they look at is your employment history.
Lenders consider working consistently for the last two years to be a solid employment record.
Now that doesn't mean you have to have been at the same job for two years - only that you have been working consistently without any large unexplained gaps in employment. In fact, job moves are looked on favorably if the result has been better pay. Lenders can also get an idea whether you will pay your mortgage back based on your history of paying other bills. Lenders learn your bill paying history by obtaining your credit report. Your credit report contains a detailed history of your debts, your monthly payments on those debts, and how much time you have left to pay off certain debts.
