A great question for your favorite bank or lender.
I have seen one year income used as 2 years if it's substantial income. In other words, the lender took the one year, divided it in half & counted it as 2 years. Again, a person must have a high enough income to make this possible.
There are lots of programs out there for first time home buyer's that work around traditional issues. For example years in school that might apply towards his work, etc. There are a lot of criteria that go into loan approval and two years on the job (or similar line of work) is a guideline, not a requirement for some loans.
Hope that helps!

Hi! Great question for a lender! If you or your son could call or email me I could recommend a couple of lenders who could answer your question. Then when he is ready to buy a home & he is not working with a Realtor give me a call to talk about that home he is wanting to buy!
