A tenant has been in my single-family rental for three years, on a month-to-month basis. When she moved in, I collected a security deposit (equal to a month's rent) and the last month's rent. Last year, I raised the rent by $50 per month. I now want to terminate her tenancy with a 30-day notice. I know that I have been paid for the last month, but can I legally expect her to pay the extra $50?
