There was the leasing agent, planners, an interior design team to choose from the color palettes, others for security, construction inspectors, etc.

Those are all computer algorithms that can't take specific details into consideration like paint color, flooring, countertops, room layout, quality of neighbors, and many other factors.Use their numbers as a beginning analysis but then actually look at comparable rentals on the market and compare them to yours.

This will give you what is known as skin in the game- and make you into it actually investor - with something to invest. 

For what it's worth, I don't think you should expect your GC to put skin in the game. 

Everything aforementioned is great information, I just wanted to provide a little extra color in the hopes it assists your client's decision.

So it's not uncommon for travelers to leave the house at night and come back when it's still dark out, especially during winter.

It has come to my realization as I put up all of the money I have worked so hard for, that he has no skin in the game.

As for counters, I go solid surface (a solid colored granite or quartz).  

They were talking about paint colors and how things made them feel and I was talking about cost per sq foot and the value of the property, so there was a disconnect in how we perceived the buying process. 

Three months of being under contract and having the deal fall apart due to you not producing any qualified buyers will get under any seller's skin.
