In my case, my parents aren’t wealthy (retired schoolteachers). They offered to help my brother and I with college - by which they carefully explained that they meant we had best plan on playing the whole shot ourselves by any means we could devise (scholarship, loans, etc.) and they would help as they could. As it turns out, they just paid my brother’s tuition (he went to in-state school, but had no scholarships and minimal loans) and helped me pay off my student loans (my tuition was mostly covered by scholarship - the loans were primarily for room and board and books and so forth). I sincerely doubt the dollar amounts worked out evenly - I was a much better student than my brother, but went to a more expensive school. However, neither of us feel like we got short-changed, either. We both had to do some stumping to get through school - and both of us damn well had jobs while we did it.
When my brother got married (some years before I did), my parents - as a wedding gift - helped him build his first house (actually, it was a duplex - they rented out the other half). By that I mean literally they went to the town he was living and my dad (who is a professional carpenter) and my mother (who can follow directions given by a carpenter) and helped him build the house. They actually did most of the non-plumbing or electrical work and paid for a portion of the materials. My brother and his wife helped out evenings and weekends. The result is that my brother got his first house for a vastly smaller amount than if he’d had one built (or bought one ready-built).
When I got married, my parents informed me that when I was prepared to purchase a house of my own, they would be presenting me with a cash amount that was “equitable”. They were no longer really physically in a position to do the construction themselves at that point, and knew it was likely to be a few years before I was looking to buy a house. When my husband and I were at a house-buying position, my parents did, in fact, present us with a cash amount. It was not the same as what they spent on my brother’s house - it was bigger actually. My mom decided what she thought was fair and gave us that much - we were (and remain) deeply grateful to my parents. I believe they also made a fairly substantial wedding gift of cash to both of my half-sisters upon the occasion of their respective marriages - although I’m not actually sure, because my sisters are quite a bit older than I am and got married when I was not at an age to give a rat’s ass about such matters.
As it happens, given market conditions (both the overall real estate market that crashed between when my brother bought his first house and when I did) and the respective locations of our first houses, I was able to buy my house outright in full, where my brother had a mortgage on his. Neither of us feel like we were treated inequitably - and both of us were (and remain) deeply grateful to my parents. It so happened he bought his first house at basically the height of the market in a fairly robust (but not ridiculous) market, and I bought my first house at the absolute bottom of the market in one of the hardest-hit markets. Approximately the same cash had very different buying power.
My mother (who handles all the financial transactions in my parents’ household and always has) viewed this as essentially paying us our inheritance at a point when it’s more useful to us than when they pass. Since the youngest age of marriage among my siblings was 26, she was fairly sure that by the time they died, we would quite likely be at a point in our lives when a large capital investment would not have anywhere near the same beneficial impact as we were at the time we got married. Her thinking was essentially that a head start on home ownership was highly likely to be a good basis for future prosperity. Thus far, she’s been correct about that - even with the housing crash and economic downturn.
She also informed both of us that if their financial picture had changed and made either of the house-buying gifts (or the college education for that matter) not financially prudent for them, one or both of us would have been out of luck. She still expects us to be financially prudent and responsible - and wouldn’t have given us a thin dime if she had a thought that we wouldn’t be both of those things. She taught us how to manage our money.
So the TL;DR version of this is basically that my parents handled both college and home buying assistance as a GIFT (i.e., something we had no right to expect) and as a form of early inheritance that came at a time in our lives that was more useful than my parents’ eventual death.
