New RE investor -need that BRRRR !

[Rafael Barahona]

Hello BP! I am a fairly new RE Investing. Currently self manage my own 2 Rental properties and seeking for my 3rd investment property this year (hopefully). I am Currently enrolled on a Real estate Broker course and learning a ton, so hoping to take the test next month.

I have been looking at the BRRRR strategy but not having any rehab experience puts me somewhat hesitant to do this.
is there any experienced Fix/flip investors out there willing to give a crash course to somebody looking to get started? 

im more looking to make sure my calculations are as close to spot on as possible for our local market. (ARV, appraisal, rehab costs etc.) Do's and Donts, common mistakes etc.

Im Possibly looking to do a BRRRR with a foreclosure purchase in a A or B Class Area.

thank you in advance
