<prompt> Human: Im graduating from college this December and starting a job in January for 80k a year, plus a 4k signing bonus. After taxes, this is about 4500k a month for my state. I have no student loans, no car payments, and my rent is 400month I share an apartment with my little sister. I split electricity, gas, internet with my 2 roommates, so based on how I live now, theres pretty much no way Ill spend more than 1000 a month Probably closer to 700month, but Ill round high. So Ill have 3500 extra per month. Im planning on putting the max amount of money into my 401k that my company matches, and putting the rest into a savings account. I wanted to help my youngest sister through college 4500ksemester, but my parents rejected that idea - their business is going well so wont let me repay them for my tuition, either. They suggested that I instead invest in property. Housing prices are rising rapidly where I am Austin, TX, and my sister wants to go to college here in 2 years. Id rent it out to other college students to make money in the long run. Im a bit worried about this idea, because I feel like I might bite off more than I can chew with managing the property and such, even if it pays off in the end. If this is a good idea, any tips would be much appreciated. : Some other Ideas that I had after reading through the wiki are: Save to take courses for a masters degree my company may pay for this for me, though or business classes StocksIndex Funds - Which I read about in the wiki a little, but I have very little experience on the matter. Ill read up on this if its a good option Are there better options? Or should I just keep saving for longer? If so how long? Im 21 and want to just focus on getting a lot of job experience, so wont have any foreseeable big expenses not planning on getting pregnant any time soon, which is why Im okay with having my extra money untouchable for a few years. The big milestones that Id like to reach with this money: Have enough to partially or fully fund my own start-up software company in 8-10 years. Have money for down payment of a house in 4-5 years Thanks for any advice!edit: this is after I save for 6 months for an emergency fund, ofc :  <response>: Its a bad idea. Its not a good idea to invest in something where the smallest unit of that thing is several times your annual income andor net worth. Its literally putting X00 of your eggs in one basket. And property costs a lot to maintain!Invest in something that will allow you to diversify. ETFs and similar have a good return and are very liquid.If you meant investbuy a house to live in thats a different question and has different variables
