Prorated Rent and Tenant Rules in Gresham

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 Gresham rent near $1,500/month, the standard method divides monthly rent by the days in the month and multiplies by days occupied. Oregon sets no cap on security deposits, but the landlord must return the deposit, with an itemized accounting of any deductions, within 31 days of move-out. A 30-day written notice generally ends a month-to-month tenancy in the first year, with a longer notice required after that.
