I have been in talks with a GC in Georgia and his method of building is: He builds everything at costs and doesn't include any markup or fees, he oversees everything, I only supply funding, and we split 50/50 the profits after paying back the bank and all other associated fees.Since I am only supplying the funding for the deal, is there a way I can structure doing this so that this is considered passive income for myself since I won't be involved with the construction or overseeing the project?

Quote from @David Tiefenthaler: Brandon is a great teacher and a good person, but that book teaches methods that are not good for investors and are more likely to get you in trouble.

I would also suggest you reach out to someone who has experience in the BRRR method of investing.

Using the BRRRR method, you can actively increase the property's value, which is then reflected in a new appraisal when you refinance.

It sounds like you have already defined your investment strategy using the BRRRR method.

Changing Your Accounting MethodGenerally, you must get IRS approval to change your method of accounting.

I plan to do the BRRRR method (They are in their early 50's so they have about 15 years or so before we would want to sell or I buy them out of their properties for retirement) .Thank you in advance for any advice! 

If you have a property and are looking for investors, what are some methods you can use to find genuine investors?

By end of year I am estimated to have saved 45K.I am looking for alternatives to purchase more doors specifically the BRRRR method.  

All you need to do is find a lender that understands and specializes in working with BRRRR method investors that flip at scale and at speed.
