Doesn’t seem out of line if you expect to hold for a long period and have the income to do so.

If your friend has followed her own advice and bought good securites and has held them she has done well. If she has bought real estate nd held it without refiing out she has done well.

If this has been her strategy show me what she is doing that is wrong.

I tend to think the real deal here is rent is cheap. Rather than arguing over buying a home or timing a market just let her know you like good deals and think renting is a good deal at the moment.
