I am interested in learning about investing in real estate, especially fix and flips and the BRRR method, using my rehab knowledge and my guys on slower days to build equity.  

Most cost segregation firms will provide a free cost/benefit analysis quote to help you determine if the tax benefits from the study will outweigh the costs.

What should it cost?

It would/could be only 15% capital gains tax and yes you could/would deduct all selling costs including commissions and transfer taxes.

It is my understanding that the new owner will have the house at the cost basis of my purchase price, for calculating capital gains taxes or depreciation.For gift tax purposes for you - FMV.For capital gain tax purposes for the recipient - your original basis/purchase price 

To be brutally honest i don't care if it's at cost, below or above, I only care what it is exactly and how much. 

Rehab cost overrun is where most BRRRR investors and flippers go wrong.

Here’s an example of bonus depreciation.WHAT IS THE COST OF A COST SEGREGATION STUDY?

The reality is you have to pay for services like this and be prepared to eat the cost if the deal doesn't pan out.

Asking price, cost of rehab (plus time to complete), ARV, and rent once rehab is complete.Asking price $50k.
