If the principal EB-5 investor with a pending I-829 does not stay permanently in the U.S., how does that affect their case approval?

My mother is the principal EB-5 investor with a pending I-829 and I am her dependent. Over the past 4 years of her I-829 pending, she has filed for multiple I-131s or visited the U.S. every 6-7 months, but never permanently lived in the U.S. Unlike me, who has a job here, she does not have a job so does not want to live in the U.S. Is it ok for the primary petitioner to never live permanently in the U.S. if she constantly gets I-131s approved or visits the U.S. every 6 months? She has a bank account and owns a property, but never stayed in the U.S. for more than 6 months over the past 4-5 years since getting conditional permanent residency. Does the fact that she never lived in the U.S. permanently affect our chances of getting the I-829 approved, or getting it faster?
