I'm not sure why you would want to wait a year. It is hard to answer without more information. But, my first answer would be to find an honest, qualified lender. They will be able to tell you guidelines for underwriting where employment is concerned. I work with several very good lenders, but the guidelines do not seem to be the same from one to another. Sometimes I'm told as long as it is in the same line of work, it doesn't matter. Sometimes I'm told you need a minimum of two years at the same company and so on............
Check with a lender and then get moving. Home prices are low and so too are interest rates. I'm not sure why you would want to wait!
