@Kristi R. - I'm curious to know what others are saying. I've been at this (in theory) for about a 1+. In that time, I've paid a nominal fee to a local real estate investor's association for mentoring; obsessively listened to BP podcasts; spent hours pouring over blogs; and spent hours more watching YouTube videos on investing...
Despite all of my preparation, I don't feel prepared to flip (I am working on other types of deals, though) . It dawned on me a few months ago that I would never feel fully prepared; that's just the nature of some things. I'm a lawyer and I can tell you that no matter how many hours I've spent preparing for a hearing, I simply cannot anticipate every curve ball. If I tried to, I'd literally never take any cases for fear of the unknown. I think real estate may be a little like that and I recently decided to just jump in. I'm currently working with a realtor to find my first property to flip.
That being said, there seem to be a few types of calculations and things to keep in mind when flipping. It's been discussed on these boards ad nauseum. If you get a firm grasp of those things I think you'll be ok. But you won't know unless you try. Best of luck to you!
