You are possibly setting yourself up for immediate failure.....there are too many moving parts and too much money involved to mess up this facet of the project.

Without this foundation any money spent on gurus, courses, books mentorships that teach techniques and methods is WASTED, even if the methodology being taught is valid.  

Bandit signs, cold calls/texting along with direct mail is the method most people use.

However, we typically use the FHA-203k loan because it involves a renovation, which I highly recommend if you are looking to really boost your equity and have the cost of the renovation wrapped into your loan with a VERY LOW AMOUNT OUT OF POCKET.I like the FHA loan, but honestly, the Fannie May Home Style is an even better product at this point because you just have to bring a bit more cash to the table 5% vs. 3.5% (w/ FHA), but you have a bit more flexibility.  

An LLC also makes refinancing in the BRRRR method smoother, as many lenders prefer loans through an entity for multi-property investors.Starting with the right structure positions you for long-term success.

They should have a process for this that will likely involve probate.

Like anything involving holding of funds, your client should do his own due diligence and you should refer several to him if you are going to refer any.

The BRRR method is not about "numbers working" in a given market. 

I am the only real estate investor with my bookkeeper and at first she thought this was a little overboard but once she started setting rules in Quickbooks to simplify her work she quickly realized how simple this method makes things.

Its already long distance but if you have no desire to be involved, no boots on the ground in anyway, it may be hard to make it work.
