Hey Mike,
I think it also kind of depends on the availability of deals that come your way. For example if you want to do flips but can't find any deals where your purchase+holding+renovation cost is low enough to turn a profit when you sell, you probably will stay away from flips in that case. The same is true for rentals. My advice would be to start networking with investors locally. Maybe even find a mentor or a partner to do a deal with (someone with a proven track record). Talk to realtors, customers you work for, friends, family, etc. Starting looking at potential deals and try to run the numbers to see if any make sense and to get practice. Don't be quick to jump the first deal that comes your way, there will always be other deals. You'd be surprised, but it doesn't always take a ton of money to by your first flip/rental if you are creative. Save some dry powder for when you have already done a deal or 2 maybe with a partner or on a smaller scale and you are confident you know what your doing, at that point you will be ready to go all in. In real estate leverage is a powerful thing if done correctly so don't be scared to use the bank's money. For example at 70% loan to value $300k turns in to a $1MM rental portfolio.
