Generally, with an income of $50,000/yr and no other monthly bills other than utilities and insurance, you should at least qualify for about $175,000.00. If you have a monthly car payment of say $500/mo, and minimum credit card payments of say $200/mo, subtract $70,000, or $105,000. There is flexibility in the VA guidelines so these figures are not etched in stone.
You do not have to be employed for two years if you are not on probation at your new job and you can document that your new job is based in part on your prior experience. For instance, if you previously worked in food service in the Military or elsewhere, and you get a job as a cook, your lender can obtain a statement from your employer that you are not on probation and the prospect for continued employment is good. If you are and independent contractor, a Realtor or Carpenter for instance, then you will normally need two years tax returns to substantiate your income. There are exceptions to this guideline as well.

Good Luck!
