I mean obviously other things are a factor but their leadership might be the “bet”

That means stocks go nowhere in short term.There have been plenty of zero gain decades in market history and this would be a prime place for one of those to begin.Individuals with ACTUAL earnings and dividends, yes,Especially if buy and hold for the dividends and price paid is not a hugh factor in a ten year hold, otherwise total market etf's, passive vehicles etc NO! 

Maybe worried about hassle factor/ being sued. 

Make sure you factor that into the overall profitability of the deal so you get your half!

Will depend on several factors like the type of property, type of tenants, your risk tolerance, other assets you own, your estate planning, laws where the property is located, etc.Any lawsuits would be limited to the assets of the LLC and not your personal assets (assuming you run the LLC appropriately and the corporate veil is not pierced).

Certainly doesn’t sound like this method makes the decision as clear-cut, so I want to understand ‘why’ I would be analyzing the return in this manner before factoring it in to the decision.

If they uncover any thing that they want fixed, you can counter with you've lived there for 6 years and should have known it was a problem and factored it into your offer. 

The biggest factors are utilities that cost a lot to put in place and grading/exporting dirt.

@Marcus Auerbach those are very good points for me to think about and factor in.

Especially when you factor in the labor to install, for a marginal amount more, you get a much more durable product with a deeper wear layer.
