Not a specific book but podcasts and discussion threads on how to compute CoC, what expenses to account for and estimating rehab costs were the most valuable learnings for me. 

The other part of wholesaling that is a possible red flag is Equity Stripping, AKA Illegal Flipping, this was heavily regulated till a few years ago by lenders, especially M.I. companies, they have relaxed the rules, but was a problem pre and post crash. seeing the increase in this activity seems eerily familiar,  like 2007 all over again. just be careful especially with your license, Disclose Early, Often, and in Writing, My license is too valuable to me to be involved in this type of transaction, so i steer clear. if my entity is on the contract, I am the one closing. period. 

Ben, I can't speak for any of the REIA's but I've heard they are extremely valuable.

Becoming an agent has costs to operate Day 1 which includes: additional car insurance (required to drive people around), licensing fees, dues (state and national), fees to operate a Supra key, to be on MARIS (MLS), prepaid legal fees, etc.

I'm a SD resident entering the game and buying two SFH's in the KC, MO suburbs and am looking for recommendations on local (San Diego) CPAs that specialize in REI, and specifically have a knowledgeset for investors with holdings outside California.In addition, as someone starting out with their first holdings, any recommendations on things to specifically knock out right off the bat with my new CPA would be much appreciated!
