First, you should get pre-qualified. This is important in the sense that it tells the seller that you are very serious about purchasing the home and that you are able to qualify for a home mortgage. What happens is, you provide the mortgage company or bank with the information and based on your salary or credit history, they figure how much you can spend on a house.

If all the requirements are met on your mortgage application then you will get your home mortgage. After you pre-qualify, never think of changing the job or quitting. You should also not plan to buy something, which requires a huge loan. You should try to stay at your current place of employment for just a little longer. However, if it is not possible then you should get another job but you should tell your home mortgage company about the change of your job. This is important as if they find out you quit right before closing then they might can cancel the home mortgage.
