It is dastardly hard to keep things “even” or “ fair” when it comes to parental money, especially if you are dealing out tangibles not cash
Fortunately with my sibling, our mother bent over backwards to do the “fair” thing. I remember my mother giving my brother some property and I think she out and out gave him their version of “the lake house*.” It was a long time ago and I was out doing my own adult life thing, so I cant remember details. And then, being a good mother she felt guilty and offered to buy me property there as well. My reaction was oh hell no keep me as far away from that Nowheresville as possible. So,she gave me cash! Nice.
Years later they got rid of that place because they were past the stage of wanting to drive to an a half hours to go to a weekend place.
On the topic of advanced education she remarked more than once that she paid so much more for my brother than for me. Thinking back about it I really do not think that’s true. I think that was just mom math, but whatever, even if true it didnt bother me. I paid for a few years of college but that didnt kill me and was actually good for me.
* It was a house, of sorts. It was by a lake, sort of.
