I just took out the dishwasher at my rental last month when the kitchen was re-done. Dishwashers break down often and create headaches. My tennant didn’t use it anyways and was happy with the new kitchen. I would allow a tennant to buy/install a dishwasher if they had at least a 1 year lease and were willing to pay for purchase/install. As far as paint, it also depends on how long the lease was and if they were willing to re-paint when they move out or have the amount it would take to paint taken out of deposit. I would prefer that a renter not paint at all. There are problems that arise when trying to match colors down the line. White/eggshell white that are commen at paint stores are the best for rentals. It is easier to match the paint when you need to do touch-ups.
