Kevin Miller bought a house in Atlanta in 2009 and took out a mortgage. He lived in the house until 2012, when he accepted a job in Chicago; from then on, he rented the house. He received a letter demanding payment from a law firm on behalf of the mortgage company in 2014. By this time, Miller was renting the property to strangers and thus was making a business use of the property. Miller claimed that the law firm had violated the Fair Debt Collection Practices Act. The law firm replied that the letter is outside the scope of the Act because it was trying to collect a business debt rather than a consumer debt.

(a) What are the arguments that the debt is a consumer debt?

(b) What are the arguments that the debt is a business debt?

(c) Which arguments would prevail? Explain.
