Is prorated rent due with the first month or the second?
Move in on the 20th and two reasonable people can disagree about what you owe at signing. Both conventions are legitimate — the dispute only happens when the lease doesn't say which one applies. Here's how each works.
Convention A: prorate the first month
At move-in the tenant pays only the prorated partial month, then full rent on the 1st of every month after. Example: $2,400/month, moving in July 20 — the tenant pays $929.03 at move-in (12 of 31 days at actual-days rates), then $2,400 on August 1.
It's the simplest version for tenants to understand, and the math matches intuition: you pay for the days you're there. The trade-off for landlords is less cash collected before keys change hands.
Convention B: full first month, prorate the second
At move-in the tenant pays a full month's rent, and the proration is applied to month two. Same example: $2,400 due at move-in, then only $929.03 due August 1, and full rent from September onward.
Landlords often prefer this because a full month plus the security deposit is collected up front — more protection if a tenancy goes wrong early. Some tenants actually like it too: the discounted month lands after moving expenses hit.
What matters is that the lease says which
No Maryland statute dictates either convention — proration is entirely a lease term. A good lease states three things: whether rent is prorated, which daily-rate method applies (actual days, 30-day, or 365-day), and whether the proration hits month one or month two.
If a lease is silent and a dispute lands in front of a judge, the tenant-pays-for-days-occupied logic of Convention A is the easier position to defend — one more reason to write the clause instead of leaving it to argument.
Frequently asked questions
When is prorated rent due if I move in mid-month?
It depends on the lease's convention: either the prorated amount is what you pay at move-in (with full rent starting the next month), or you pay a full month at move-in and the prorated amount applies to the second month. Both are legal; the lease should state which applies.
Why do landlords collect a full month up front and prorate the second month?
It ensures a full month's rent plus the security deposit is collected before the tenant takes possession — more protection early in the tenancy, when the landlord knows the tenant least.
