Shall I replace appliance when renovating the kitchen?

[Hui Kiang]

Hi all,

The kitchen in my rental house has been there since the house was built (50+ years). As it's such an eye sore, I finally decide to replace the cabinet and countertop this time. All the appliances (dish washer, oven/stove, refrig) are old (prob 20+ years old) but in working/fair condition. Shall I replace them as well? 

One thing I've been noticed is the new appliance tends to break in less than 5 years. Those digital panels are very problematic. My rental is in SF Bay area B neighborhood. If I don't replace them with new one. Will it ruin the potential to get the good tenants? 

Thanks!
