<prompt> Human: Long story short: My mother died in the spring, leaving me and my brother who is now in my care around 200,000 in cash from her estate split equally, were in the UK.Before this, my own personal savings were well shy of 10k, Ive never had to deal with this amount of money. My aim is to die having made it a bigger sum than we inherited to our own children, how can I assure this? My brother is a minor, so I will be in charge of it until is he around 25 in 12 years.I have already bought a property worth 130k in cash on the advice of many around me, though will still have a couple hundred a year in sharestock income - my brother will have the same in child pensions and well still have 70k to investsave. I earn around 1200 a month take-home, and in the UK you are entitled to around 6K a year in benefits as a single carerlow income earner, which I also now receive.What investments can I make now to ensure that by the time my brother 13 is 25, his half of the estate has grown? aside from equity on the property, which Im sure of. How I can I use the remainder of the funds best to generate more passive income streams for us? I am willing to give up work for another role or start a business if either of those leaps would be more effective, as I realise we have more in savings now than many people may achieve in a lifetime, which is a huge responsibility, but I dont want it to become a burden... any advice GREATLY appreciated.  <response>: I have already bought a property worth 130kWhat do you plan to do with this? TBH, real estate investing, contrary to what many believe, takes a lot of work that I wouldnt really consider it passive income. If you plan to do this full time andor live there, I guess thats okay but I thought you should know that its only a good investment if youre willing to put enough work into it.What investments can I make now to ensure that by the time my brother 13 is 25, his half of the estate has grown? aside from equity on the property, which Im sure of. How I can I use the remainder of the funds best to generate more passive income streams for us?Twelve years is generally considered long enough to invest in an equity fund something like CSUK if you think youll be able to stomach large fluctuations in value. Its likely to increase in value over that time period, but theres also a chance it could decline. Also, its probably not going to provide a steady passive income stream.Gilts are probably a safe bet if you want something that has practically no risk of capital loss assuming you hold them to maturity and regular interest payments. However, with yields at around 2, youre only going to get around 1,400 a year if you invest 70,000. Its not a lot of money, but its better than nothing.I am willing to give up work for another role or start a business if either of those leaps would be more effective, I realise we have more in savings now than many people may achieve in a lifetimeThis is probably not what you meant but its worth saying just in case: While 200k seems like a lot of money when youre young, its far from being quit your job and live off the interest-money, unless youre like 65 or something. Youll still have to work and youll be far better off setting this money aside and pretend you never had it.
