It sounds like you have a solid plan in place, and I'll provide some insights and advice based on your questions:Maximizing Investment Longevity:It's a smart move that you're house hacking with an FHA 203K loan, remodeling for appreciation, and then refinancing to extract equity for other investments.

While forced appreciation—that is, renovating buildings to raise their value—is the main method of extracting wealth in the BRRRR approach, long-term property appreciation can also boost total returns on investment.Financing Options: To finance the purchase and renovation of properties, investigate the availability of financing options such as hard money loans, private lenders, and traditional mortgages.

instead, they expect you to extract and fill out a GENERIC 'organizer'  when you try to list the data that is missing at the bottom of the 'organizer' they dont read it!

I am a seasoned multi-and-single-family property manager in the Charlotte (and surrounding) area.Vendors: I always ensure to connect with at least three specialists in the same field, for example: carpet cleaners/replacements, roofers, emergency services (water extraction or organic growth remediation) this way when it comes time for their services you can get a bid from each of them.

You have to be prepared to really push yourself to extract the maximum potential value. 

But yes, they can slice and dice their plans to extract maximum revenue from each customer.

After the property is renovated and rented out, they seek to refinance the property with a traditional mortgage to pay off the hard money loan and potentially extract some cash.However, some lenders impose a seasoning period for refinancing, which means that you must hold the property for a certain period (often six to twelve months) before refinancing is allowed.

However if I do a BRRRR I can achieve infinite return by extracting all of my investment.

Imagine the cash flow I could have if I desired (my cash flow is not great because I extract value regularly and because I prefer my return to be in tax free or tax deferred sources and cash flow you get taxed on yearly).Case Schiller used to (maybe still does) publish a residential market performance ranking since 2000.  

I would not go through the cost and pain of extracting every dollar of equity.
