If they are on a month to month, I would serve the notice of non renewal.

@Gash Nookala,Renting can indeed be slower in winter, but here are some tips to boost interest:Enhance Listing: Ensure your listing has detailed descriptions and high-quality photos—consider professional photography if needed.Competitive Pricing: Double-check local comps; even a slight price adjustment or incentives (like a reduced deposit) could attract more interest.Broaden Marketing: Beyond Zillow, Hemlane, and MLS, use social media, community boards, and local business connections to reach a wider audience.Flexible Lease Terms: Offering shorter or month-to-month leases might appeal to tenants during this slower season.Local Property Manager: A local pro can tap into their network and help fill the vacancy faster.These steps should help you find a tenant despite the seasonal slowdown.

My tenants lease is due to end 2/2/2025, is it 30 day notice or 60 day notice of non renewal in CA?

@Hai Le - Usually you have to provide written notice / 30 day notice if you decide to not renew their lease or even just asking a tenant to leave.

Most people are happy just to not take a loss each month. 

@Alex SilangFirst I assume it’s a month to month lease as you cannot raise it if it’s a long term leaseFor me that is not something I would do, If you want to raise it to market rent then do it, don’t adjust rent because you had an unexpected cost.What if they turn around and walk?

This is the equivalent of a car salesman pitching the "monthly payment" of a car instead of the actual price of the car.

Make sure you receive PRINCIPAL plus interest each month (loan amortization) so that you  will receive $3226.72 each month for 36 months.  

Every month you are paying $400/month, almost $5k/year for your properties. 

She can set up payments to be paid on the 1st of the month and no one is driving 24/7.
