Prorated rent is what you pay for a partial month when you move in or out on a day other than the first. With average Olathe rent near $1,200/month, the standard method divides monthly rent by the days in the month and multiplies by days occupied. Kansas caps the security deposit at one month's rent (one and one-half months if the unit is furnished) and requires the landlord to return it, with an itemized statement of any deductions, within 30 days of move-out. A 30-day written notice generally ends a month-to-month tenancy.

| Security deposit limit | one month's rent (one and one-half months if furnished) |
