This is a discussion in my Business 108 class. First, watch the video that I attached to the attachment. Then answer the following questions:
1. Are the rental scams on sites like Airbnb.com (Links to an external site.) or HomeAway.com (Links to an external site.) the basis for a lawsuit (cause of action)?
2. Is a breach of contract lawsuit possible? Why or Why Not?
3. Is a negligence lawsuit possible? Why or Why Not?
4. Is the (purported) renter liable for contract and/or tort damages? Why or Why Not?
