If you had access to $400k, how would you build semi passive $100k annual cashflow?

$100K cash and up to $300K HELOC variable interest only payments (prime +.25). Looking to learn some great lower risk strategies for those that want to share! I own and manage 3 short term rentals, and have done for 3 years ($50K gross profit each year across them). Not interested in flipping. I could buy a large STR in my market DSCR but looking to diversify! Happy to trade my STR knowledge for those that want to Private Msg! Target timeframe of 3-5 years. Annual Appreciation 3%+ target. Self managing an option but a PM option is cool too! Happy to discuss partnerships as well.
