This is a question that you have to ask yourself. Not only do you have to come up with the down payment and closing costs. You also have to consider your total debt and available credit, because becoming a home owner also comes with added cost (e.g., Property taxes, Maintaining the property, Renovations).
Discuss with a mortgage specialist before you start searching for your dream home! This is the best recommendation we can give you. Not only will it save you time, but your real estate agent will also be more productive and efficient in finding the right home for you. Visiting properties that are above your budget could be hugely disappointing!
