Hey BP,I initially wanted to start out flipping but now I really would like to take advantage of the brrr technique.

There are a lot of techniques and tricks that you can do to ensure a successful campaign.  

I'm just beginning to research different marketing techniques.

I had thought of that as a technique before, but i didnt follow thru because many of the pictures i noted thru looking up houses on google is that the image is often from 2014...and MAYBE it is still a vacant or abandoned (looking) house, but i figured that it could easily have changed hands by now, and i'd be doing it for nothing. 

Whoever said you have to stucco everything also, whatever happened to painted brick or block.There has to be some ways to build cheaper with newer techniques.

Not looking for any one to do anything for me just would like to talk with someone who has been successful using this technique.

Second @Dylan Tanaka comments.We also have found that a great technique is a pre-recorded message the seller can listen to when responding to your marketing.

B and C-class properties are a bit intimidating, but I've been looking into techniques/tips for tenant screening, which should hopefully alleviate the worst of any potential issues.

Also consider using some other techniques like lease options, contract for deed or subject tos where you don't need financing.  

Every sale person is different so different techniques are needed.
