@Tanner Bryant- Everyone that has commented here is right. your question is super broad and did a decent job of getting the conversation started but now you need to narrow down and come up with your goals.
fix and flips are great
buy and hold is great
Brrrr works great
house hacking is great
syndications, multi family, rv parks, modular home parks, and raw land development are all awesome moves....
What is your personal tolerance for risk? How much money do you have to invest? Are you trying to invest with $0 down, or do you have some liquidity? what would happen to you if your investments start to lose money? are you protected? One of the great plays with real estate is that not only should rental property cash flow but in most cases real estate values inflate over time.
Being able to add extra arbitrage points anywhere you can while also reducing your risks is a smart play. I really like using Whole life, and IUL policies to create some extra arbitrage points while allowing you access to your money, and offering you other statutory protections from things like taxes, divorce, bankruptcy, and providing living expenses, and a death benefit for your heirs. Just make sure to work with a reputable and extremely knowledgeable agent who will set up the contracts properly so that they will perform the way that you need them to.
