Average Homeownership Expenses Homeowners need to Consider

I was asked by a prospective homeowner...'In addition to my mortgage payment, what expenses do I expect to have when I purchase a home?'

With the costs of home ownership in mind, I drafted a simple spreadsheet of basic household expenses to provide homeowners. This may help some first time home buyers put the "real costs" of home ownership into perspective.

Let me know your thoughts of these and other expenses I need to include in this list:
