It wouldn't be an eviction because the lease would clearly state it is for 1 year and 1 year only. Turning over a unit would involve maybe a day of work getting a listing posted and scheduling showings then a few hours of showings. There would be no issue getting a new tenant in the current market and the situation isn't changing anytime soon. The increase in rental fees would cover these costs easily and most large landlords use a property manager anyway so little headache on their part to do that.
