Hey @Meredith Parker. Welcome to the world of RE!
I am relatively green compared to many people in this forum, but I'd say these are all great ideas, depending on your situation. Though here is my 2 c.
I personally shy away from flips. Contractors "quality" varies GREATLY. A not so great contractor has 2 main risks: Price creep, which will more often than not end up costing you x2 what the bid was, and time creep, which can also take twice as long as expected. Once you finish the physical flip you then have to market and sell the property. Closing can take 30+ days.
So the worst thing you can do is finance a property for a flip, at that point you are also liable for a monthly financing payment as the contractor is taking their time and when your house is on the market for sale.
Cash buys for flips are much safer, but there is still the issue of finding a reliable contractor (I'm still yet to find one).
If you can find a good deal that you can conservatively account for the above variables and still come out on top, then its a good deal and you should go for it.
I'm personally a big fan of the BRRR method. It leaves you with a property in hand, that if you bought it right and renovated right, has a good cash on cash value long term.
