Can a tenant renew the lease?

A demand letter would probable cost between $100 and $150. However, if you have a tenant that is six months behind in rent, you're better off posting a 3 day notice to vacate and evict the tenant and get a paying tenant in the property. If the tenant hasn't paid in the past six months, it's unlikely the tenant will start paying now. You can always sue the tenant after you evict them (or even during the eviction process) but getting them out will allow you to place a paying tenant in your property.

Witnesses are not required for a residential lease agreement in Ohio. However, if the term of the lease is 3 years or longer, the signatures must be notarized. I hope this helps.

The answer to your question is contained in the lease. All rights and obligations of parties to a commercial lease are controlled by and provided for within the lease. If your lease provides for early termination by the landlord, then the landlord can exercise that option. If it doesn't provide for early termination and you are in compliance with the lease, then they can't terminate early (at least not without your consent). You should retain a local attorney who can review the lease and provide advice concerning your specific situation. Best of luck!

I am a WA State attorney, and I counsel both landlords and tenants in WA who end up having landlord/tenant conflicts. It would be smart of you to have your first lease draft reviewed by a knowledgeable WA State landlord tenant law attorney. The biggest problems that arise include return of a security deposit and/or billing for additional costs after move out; tenants failure to comply with terms of the lease and/or HOA rules; and issues/questions regarding renewal of the lease. The Residential Landlord Tenant Law can be found here: https://apps.leg.wa.gov/rcw/default.aspx?cite=59.18 Two changes were made in 2023 alone. In addition, some cities, like Seattle, and unincorporated King County, have additional requirements to be aware of. You may want to consider joining an association of WA landlords - I think there's a statewide one, and there may be county or city organizations. Some of these can provide you with first draft leases and/or provide guidance, classes, and counseling. There are many places to buy leases online, but some of these don't address the fine points regarding notice to vacate or raise rent, issues arising from paying last month's rent ahead, whether or not security deposits can be applied toward the last month's rent, and so forth. An attorney who specializes in landlord-tenant law can provide you with your first lease and also be available on an ongoing basis for consultations from time to time.

I think you need to post this as a CA question, not as a WA question. However, your first step is checking government and HOA rules, if any and make sure that this is allowed. You will need to change your insurance and possibly add another policy specifically for short term rentals. Let me know if I can ever be of help with WA State legal questions!
