In my case, my parents lent me £10k when I bought a first property in the year 2000.
It allowed me to buy a 2 bed rather than 1 bed place and to have a £20k deposit which was 25% of value.
It was a loan and I had a year with no repayments so I could set up the property, then paid £100 per month. After about 4 years, they wrote the loan off.
£10k now doesn't sound so much, but it made a big difference to me then. It was important to them that it started as a loan, because they wanted me to appreciate the value of money etc etc. I couldn't get that £10k as part of my mortgage because I didn't earn enough, but I could easily pay £100 per month as I let my spare room for £300 per month. Wouldn't have had a spare room without that £10k.
They could have afforded to give me more. However, they gave me what I needed and what allowed me to do it and fund most of it myself.
My DH was left £20k as a gift ina grandparents will at a similar time (before we were together). Rather than leave all the cash to their 60 year old children, his grandparents left £20k to each grandchild. This formed the basis or the total amount of all of their deposits as all of them were in their mid 20s. What a great gift!
Not everyone can afford to do it, but for those who can, I think the pleasure of seeing the effect of those loans or gifts is absolutely huge, as well as the impact on those kids lives. I'd rather have that than another extension or luxury cruise. However, I wouldn't extend my own mortgage or make myself live on baked beans in retirement in order to do it. And I think people who honestly say they can't afford to help are better to do that than to drive themselves into poverty.
And I agree that families help each other in all kids of ways and at different times. It won't be too long until my parents become frail and need more time and care. I would hope to give them that when and if they need it.
People's needs vary. Some kids need financial help (most) but some don't. Some elderly parents need care, but some don't. Some kids or parents need emotional or mental support, some don't. I think that as families,r egardless of our ages, we just look to help each other when needs arise and as far as we can. Some people have greater needs and some people have greater capacity to help. We can all do what we can - no more, but no less either.
