"My wife and I are currently considering buying a new house, and I am considering changing jobs to earn a higher salary. I have been at my current job for five years. Rather than changing jobs, I am also considering the possibility of going into business for myself. Whatever I decide to do, should I do it before or after we buy the house?"
The answer to your questions depends on how the action taken -- changing jobs or starting your own business -- will impact the way a mortgage underwriter views your income.
