Conversely, cities boasting a lower cost of living may mitigate economic pressures and potentially result in reduced crime rates.
High rental costs can limit economic mobility, making it difficult for individuals to save money, invest in education, or access better job opportunities.

In summary, high rental costs can create economic challenges, overcrowding, and neighborhood dynamics that may increase the likelihood of certain types of crime, particularly property crimes. In Dennis, the average rental rates are $1,813 per month, compared to the national average of $1,444.
