22 year olds lucky or gifted enough to be able to borrow 10x the national average earnings from a boss paying them a high enough salary to expect repayment within five years would to be able to think about buying a small house in an outer suburb of most cities today if that was their priority. Especially if they took on extra contract work.
Obviously most 22 year olds in 1890 didn't earn a few times the national average salary. At the beginning of the twentieth century 81% of households were rented, and most of those were not nearly as nice as Frank Lloyd Wright's first home, which was not nearly as nice as it is today after decades of extensions.
