[step] Take out all of your family's bills and add up how much you spend each month on food, insurance, school, transportation, etc. Then calculate all sources of income.

Ending1: You need to buy a home within your budget. [substeps] Use online calculators to estimate your monthly mortgage payment. Ending2: It is helpful to figure out how many people the house will accommodate, as well as plan for your own living situation. [title] Meet with the real estate agent for questions. Ending3: At this time you will begin to figure out the cost for your house, whether it's health insurance, mortgage, car loan, etc. You'll be borrowing at a discount-the cost you would if you had purchased a house already. Ending4: You can also subtract the amount of monthly rent you earned. In other words, you will need more than that if you are buying a townhouse, not less.
