Hi Stargazer,
The short answer is with some really open and honest conversations and the framework of a proper legal agreement.
With regards to finance strategy it really depends on the type of joint venture or syndicate you want to do.
If it is a short term project (like a property development or a renovation of a block or units) then the finance strategy would be different to if you wanted to set up a small syndicate with a group of friends or family (and buy hold and maybe renovate a number of properties together) over a longer period of time eg. 7 years...
