    self.street_address = street_address
    self.city = city
    self.state = state
    self.zipcode = zipcode
    self.bedrooms = bedrooms
    self.bathrooms = bathrooms

    squarefeet = int(input('Enter square footage: '))
    modelname = input('What is the model?: ')
    salestatus = input('Is the home sold, available, or under contract?: ')

    home_info = Home_Inventory(street_address, city, state, int(zipcode), int(bedrooms), int(bathrooms), int(squarefeet) + ' square feet', modelname, salestatus)
    full_address = (street_address, city, state, int(zipcode)
    home_stats = (int(bedrooms), int(bathrooms), int(squarefeet) + ' square feet', modelname, salestatus)
    Allhomes = {full_address: home_stats}
