Remember not all side gigs make $$$$. Not all the time anyways.
I'm currently trying to save my wife's real estate brokerage (multiple partners) after one was doing shady **** (and leaving us with the bill) and another who basically thinks businesses run on feels and good vibes.
Partnerships can be great as you don't need to be there daily, but when you have one partner(now booted) who decided to expense her new SUV to a company that maybe made 4x that in gross income a month. (as in payment vs income, not making 4x a tahoe a month profit) and others who think that "bartering" is the solution when we have a cash flow problem, it's not always sunshine and rainbows.
But often on APC you only hear of the "I bought $3M in commercial propertys on things I bartered for starting with a potato" success stories. I suspect there's a lot more "broke even after years of effort" and "lost butt, won't admit".
I'm out about $20k if it folds which I would bet is a 70/30 odds in favor of it folding. (one partner signed a crazy long lease extension at unfavorable terms in exchance for "first right of refusal" for landlords listings/property management)
It's a bloody nightmare at the moment, as the person who was actually running the business side of things and keeping a damper on the stupid behind the scenes stuff moved to the other coast when her husband was transferred there (Military)
