Again, I’m not sure if these guys do this to everyone or if their customer service ability as partners is just terrible.

Expect a custom ADU to take 9–18 months, with 3–6 months for design and permitting and 6–12 months for construction, depending on complexity and contractor availability, and the speed of processing permits.

My advice would be is to talk to multiple investors who have real world, actual success-based experience in flipping over a sustained period.

After months of reassemble and some customization work, the property sold for a decent profit.

What I am trying to better understand is at what pointy that restaurant owner able to either delegate or reposition so he / she doesn’t have to the restaurant every day. do they need to obtain more restaurants or keep offering more to their current customers?

I dont want to hear about you selling me your course or advice at a "new customer price" .

Many commercial leases have custom clauses. 

And a general contractor would NEVER sign a customers contract 

They now use "Dave" to handle customer inquiries efficiently and promptly. 

The target customers are the unbanked and underbanked population, which is 30 million household in US.
