When buying a house, it is easy to consider how much the mortgage itself is going to cost, but there are additional fees to consider. Even on the lowest cost homes these days there is the consideration of down payment. That can reach anywhere from 3.5% for an FHA loan, to 20% for some private loans. There should also be a consideration about the cost of not only the mortgage payment but also the insurance, taxes, and possibly the mortgage insurance. There are some good calculators available online for performing these calculations. One that I recommend below even calculates the additional costs if you are renting your potential property out for positive cashflow. It will help you determine if you can really afford a home, or if a rental property will help you make positive cashflow.
