Op, we were in the same position when DS was applying to uni 4yrs ago.
Both DC had a large inheritance which they took control of at 18. DS was in Yr 13 when he got his, but we only briefly considered him using it for fees/expenses. He is currently in his final year after 2 yrs studying and a year out working. He is hoping to work in the niche industry that he did his year out in, which does have relatively high salaries, but a job is not guaranteed.
Our main thought was, as others have said, he is better using it to buy a house, rather than spending years saving for a deposit. He also has enough to do both, but he will be able to get a much lower mortgage if he doesn’t use it on fees. Ok, mortgage rates are lower than loan rates at present, but that could change. I bought my first house in the days of 14/15% rates.
There are so many stories of how young people struggle saving up house deposits, that we felt it was there already for him, so why not keep it and, hopefully, allow it to grow. We have been mortgage free for a while, and it is a lovely place to be, so if ours can achieve similar, that is great.
Both are drip feeding their money into a number of funds across a S&S ISA and a LISA, so also benefitting from 1k a year from Govt. on the latter.
We could have paid his fees ourselves, but as we weren’t sure if DD would go (no plans at moment, she working and travelling) then it didn’t feel right. Instead, we are paying something towards their monthly ISA allowance so their inheritance will stretch even further.
DS in particular has also enjoyed taking over the reins of his investments and has started to invest money in some individual shares. Hopefully his long term gains will at least match the interest of his loans.
