As a first-time home buyer, you’re probably accustomed to the monthly cost of renting, which usually includes your rent payment, some of the utilities, and your internet and cable bills. As a homeowner, you’ll be responsible for additional monthly costs that may have been covered by your landlord. That includes things like water, sewer and garbage bills, monthly HOAs (if you’re buying a condo) and the cost of lawn care. You’ll also be responsible for paying property taxes and homeowners insurance. And don’t forget the cost of maintenance. It’s recommended that you set aside 1-3 percent of the purchase price of the home annually to cover repairs and maintenance.
