Americans have homes roughly twice as big as European homes, and a far higher percentage of Americans are homeowners than Europeans. Home ownership rates are within a few percent of each other too.

I live in the countryside. In 2018 our small neighboring town of about 13k residents had their first murder since 1965, and none since. That works out to about 0.12 homicides per 100,000 residents annually. By comparison, Baltimore has 22 per 100,000 annually.
The murder thing is also an error of faulty generalization. As a counter example, Opelousas, Louisiana, a nothing town with barely more people than yours, has a murder rate of 39/100k, higher than your example of Baltimore, and much higher than New York (3.92/100k).
