Will they have their own HVAC system or be able to control the temp?

@Mel Park you don’t get to limit the amount of your liability; you get to (attempt to) control where the liability is assigned.  

Pros-Low effort-Experienced managers-Strong returns-Usually low risk (preferred returns of 8-12%, often diversified)Cons-Fees can reduce potential upside (can be 15-20% of returns above 8-12%)-Illiquid (you are committed to a certain hold period)-Little or no control

I gave too much control up without having worked with this guy before, and several aspects of the construction work went off course, including the kitchen design and color pallette.
