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

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. 

People participating are all over the rainbow in background, personality, strengths, financial position, family make up, and color. 

You can build up goodwill sending grocery cards at Christmas, having a mini fridge to rush over the moment there is a problem, giving rent credits, etc. and it will mean LESS THAN ZERO as soon as you have a late fee you expect them to pay, a pet that you cannot approve, anytime the rent goes up, telling them they can't paint the walls and ceiling the color they want... then you are the scumbag landlord.

I will admit it's very likely the next crash is something we don't see ahead, so asking for that detail is kind of moot but I still am curious on the color.

I am considering doing a light cream of some kind for ceilings walls baseboards etc.

There were maybe 3 diff models all painted diff colors and it presented really nicely as a tiny house community.

Give us some color for more feedback on your case 

SMH - nice of them to show their true colors before they rented :)
