Jumping in with a lack of rehab knowledge

[Chase Hancock]

So for the past month I have been doing serious studying into wholesaling and gearing up to start marketing in the next week or sooner. I have been listening to a lot of flip2freedom's podcast and I'm going to take Sean's advice and jump in and start taking action. I lack some knowledge on rehabbing and estimating of repairs so I'm not quite sure what I'm going to do when it comes time for me to figure that stuff out when the deals begin coming in. I wan't to make sure I have a very solid deal and that I'm confident in my numbers before I begin marketing it buyers. The last thing I want to do is start marketing a ton of mediocre bad deals.  Are there any wholesalers who have been in the same boat before but managed to figure it all out? If so, I'm curious to hear your story and would love any advice possible. 

Thank you in advance!
