hardship is must b4 getting scale
with the kind of money the lady you know owns, she can be doing anything, anywhere, in any format. she does not need to be a landlady anymore. by doing so as is, she does landlording as a non-personal, non-hand-on management, non-emotional, non-self sacriface pure business, as if she is managing a typical firm.
however, seriously, how many people here can reach her scale within lifetimes? if not, sacriface is a must in order to get the financial freedom someday.
