Question about predicable lifespan and damage to appliances

[Eric Nelson]

I understand that appliances have a "predictable lifespan". An oven/range typically have a predictable lifespan of 20 years. 

A tenant broke my 10 year old range. Am I only allowed to charge him for 50% of the cost for a replacement? The damage is not "general wear and tear". The tenant dropped a pan from the cabinet and shattered the stove top. I do not want to overcharge my otherwise good tenant. 

This leads me to my second question: how does replacing an appliance that has gone past its "predictable lifespan" work? This is assuming the damage is irrefutably caused by negligence of the tenant. If a tenant broke my hypothetical 50 year old range, what % would I be able to charge for a replacement?

This doesn't have anything to do with predictable lifespan. Your tenant damaged your property through negligence. Be very sympathetic when you give him the bill. If he doesn't pay it you can choose to keep the tenant and collect from the deposit eventually; not a good idea. Or you can evict for damages.

This should be in your lease. I've seen it recommended to have a lease clause where the tenant is held responsible for any repairs, or some part of repairs. But still, this seems to be damage from negligence. 

My son ran the car though the garage wall of a home we were renting. Should my landlord covered that since it occured within a typical homes 75 year lifespan?
