Our product offerings across our operating markets are broad and diverse. Our homes range in size from 1,000 to more than 4,000 square feet and in price from $100,000 to more than $1,000,000. For the year ended September 30, 2019, we closed 56,975 homes with an average closing price of $297,100.
Our business operations consist of homebuilding, a majority-owned residential lot development company, financial services and other activities. Our homebuilding operations are our core business, generating 97% of our consolidated revenues of $17.6 billion and $16.1 billion in fiscal 2019 and 2018, respectively, and 98% of our consolidated revenues of $14.1 billion in fiscal 2017.
