I feel that the coinvest should be meaningful enough to cause real pain for the GP in the event of a bad outcome, but not so much pain that a bad outcome or 100% loss ruins them or threatens to disrupt their lifestyle either. 

There’s a whole lot more thinking necessary than just stumbling across a YouTube video and being enticed by a change in lifestyle dream.  

Other landlords, and this usually when they occupy the property too, want to make a decision based on lifestyle criteria as much as financial factors.

So it depends on what kind of lifestyle and vibes you want (or even what beach you want to see every day) .

Anyway, I found that most people don’t want to pay for advice unless it’s packaged with promises of wealth, lifestyle, and an ability to do “it” with little or no capital.
