When we left Scotland we rented out our house including some basic appliances (cooker, washing machine and fridge). The cooker has broken a few times, we always get it fixed straight away. The washing machine has now broken and I have said I will buy a new one. However the one we left behind was an 8kg capacity machine that we needed for a large family. The family who are renting only have 2 children, so I have said I will replace it with a 6kg capacity machine but they want one the same size as the old one. This will cost me a lot more money and TBH, Christmas is only a month away. Am I being unreasonable in suggesting that if they want a bigger machine than the one I am prepared to pay for, that they purchase this themselves and keep it when they move on?
