Frequently asked questions
How do you prorate rent?
Daily rate = monthly rent ÷ number of days in the month (or a flat 30 under the banker's method). Multiply by the days you occupy the unit.
Which method do landlords use?
Most use the actual days in the move-in month; some leases specify a 30-day banker's month or a 365-day annual method. Check your lease — the difference is a few dollars.
Is a landlord required to prorate rent?
Usually not by law — it is standard practice but set by the lease. Agree in writing before signing.
