Share the cost of appliance repair with tenant?

[Xintong Li]

What do you think about sharing the cost of maintenance with tenant? I am considering putting it into lease at renewal. 

Something like: 

1. Dishwasher: 10% tenant's responsibility and 90% of landlord responsibility

2. Plumbing: 10% tenant's responsibility and 90% of landlord responsibility

....

I listed 1 and 2 because if tenant does not put sticky thing into dishwasher or drain, 1 and 2 should not happen. 

What do you think? It is in Virginia.
