@Ray Johnson thanks for your reply. I am the owner of the property. The lease went to month-to-month in May 2018, one year after the tenants signed the one-year lease agreement and moved in. They paid the first month's rent, plus a security deposit which is saved in my business checking account which they will get back as long as the apartment is left in serviceable condition. In California cities without a rent control ordinance, the rent can legally be increased to any amount once the lease has expired and continues on a month-to-month basis. A ten-percent or more rent increase is legal, as long as the tenant is notified, in writing, at least sixty days in advance. These days, most landlords in California use some type of online screening service. As for future landlords, they should sign up with Transunion Smartmove. After I had to evict another tenant back in February for destroying my other rental unit, I made a point to use T.S. to screen all candidates. No more verbal verifications, no more lies. f they have a prior eviction(s), or their income is too low to support pay the rent, then sorry, their application will be declined.
