When to replace appliances in rental peoperties

[Paul Z.]

Hi everyone.

Do you replace appliances (e.g. fridge, dishwasher, washing machine, etc.) only when they break, or replace them anyway after a certain number of years? I am thinking something like a fridge may take a few days to repair or replace, while the house is without a working fridge...

(Sorry about the typo in the title. I do not see an option to edit it.)

Cheers,
