There really is no set income level you need to achieve in order to buy your first home. The lending companies have set guidelines so no matter what your income level you are not going to be in financial trouble.If you have difficulty verifying your income, there are stated income loans that could be available to you.
There are many factors that are considered when trying to figure out if you make enough money to afford a home. Most people make enough money to afford a home, but the question becomes do you make enough to afford the home you want. If you can only afford $1000 a month for a mortgage it is not likely that you will be able to buy a $500,000 house with out a large down payment.
