Advisor: Dr. Lily Shen & Sean Wilkoff
Abstract
- After COVID-19 struck, there has become a ‘new normal’ for cleanliness standards across all industries.
- This led us to question: How do renters value ‘cleanliness’ in the real estate market?
- We investigated the relationship between listing prices & bookings and the level of COVID-19 cases at a county level in the Austin, Texas area.
- We utilized machine learning, multiple linear regression models, & critical thinking to evaluate this question
- Concluded that renters DO value rental cleanliness
