Need someone to teach me how to do BRRR

[Benjamin P.]

Hello I am a new investor at 23 years old, 

I have 20k and just wondering if someone can teach me how to do BRRR, I have the capital and just need the knowledge and how to look at deals.

For example, I found worth about 80k that is a quadruplex in a a little rough area, I can cash flow that property...I just need some guidance on how to analyze deals....also is it okay to buy in a rough area to start out.....

If there is anyone out there please respond! Thanks!
