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.

Does anyone use another method of goal setting or periodic review method?

There are small communities in Texas where the 3 or 4 small brokerages in town just keep a list between themselves or have created a Facebook group among themselves to promote their listings.I have run across a few Brokers over the years that just worked with buyers in the purchase of HUD/VA foreclosures and were not Realtors and therefore not members of a Board/MLSHowever, in any MLS that I have been involved with if the Broker is a member of the MLS, all of their agents are also required to be members. 

Many states have non-judicial options where if the contract allows for it(most contracts do) then no court involvement is required to foreclose the property.

There is work involved as you have well found out. 

Same property manager staying involved (did $56k last 12 months).  

@Jennifer FernézFrom my experience, a solid approach to real estate investing involves focusing on cash flow, building wealth, and managing risk effectively.
