Savvy home buyers who are preparing to make a real estate purchase should do their research and understand that they need to save money for not only the down payment but the closing costs as well. The closing costs can account for as much as three to five percent of the sales price in some cases, so this can be a rather sizable amount of money. Some home buyers however, may not realize that the amount of closing costs can vary considerably based on the home that is purchased. With a closer look at why this is, home buyers can make a more educated decision when selecting a home to purchase.
