A legal eviction can take up to 12 months, and in the end, it is no fun for neither the landlord nor the tenant. Better read up on the law, because you cant legally just go change the locks on the house and throw their possessions curbside, and think all is hunky dory.
Sometimes, being a landlord means thinking about the business, and other times, it means thinking about being a human and having some sympathy. Knowing that eviction can take so long, you might try cutting a deal on the rents, or forgiving some of the rent if the tenant is taking good care of the house. Perhaps you can barter some work/maintenance for rent if the tenant can perform such tasks. You need to remember that there are plenty of empty rentals right now, and just because you evict the tenant, doesn't mean that you are going to immediately begin receiving rent from a new tenant. I think a tenant would be extremely grateful if the landlord were willing to try and work out something, as everyone seems to be going through tough times. You might end up with a tenant who is willing to do anything for you, and very willing to take great care of your property.
