I would opt for somethingHard to quantify in terms of pricePurely in the "gift zone"For example, if you give them a $50 gift card there is a very real human tendency to compare the dollar value to what you perceive the discomfort to have been worth, and most years, and ESPECIALLY this year, you don't want anyone's lizard brain doing that calculation.Something like a bottle of wine and a doggie-pampering gift basket accompanied by a note expressing something like "I am thankful for you and apologize for the inconvenience you experiences around this roofing fiasco. 

But eventually watching them drink fine wine while I take tenant phone calls and refinish floors would be ridiculous.I have several rentals of my own.

Living in Oregon wine country requires a lot more cash than my farmboy roots in Michigan.

@Nicolas Bernal hi! 

Go on the bus rides with them sit through the class's  have a glass of wine after class.. 

They wine and dine you and you get the contract.

Other places have in their listing "bottle of wine waiting for you".

Insisted I took a built in wine rack, that was not there, said she had to repaint etc.   

If you're selling wine and reinvesting all profits into buying more wine, you still pay taxes on the reinvested profits.

@Marita Jojo I always do nice spirit like don Julio 1942 or a bottle of red wine like silver oak Cabernet
