Just closed on my place and realized most people have no idea when their first mortgage payment is actually due. So here's the thing—when you close, they literally tell you the payment date on this letter they give you, but basically it's the first of the month after you've owned the place for a full month. Like if you close mid-September, you're paying November 1st. Weird right? But here's what nobody mentions: the closer you close to the end of the month, the less interest you owe that first month. Still trips me out how that works.

One thing to watch though—you've got a 60-day window max for that first payment. So if you close early in a 31-day month, it can actually push your deadline earlier than you'd think. I almost missed this detail. Your lender will spell it out, but definitely double-check your closing documents because nobody wants a late payment hitting their credit.

As for how much you're paying, it's the same every month after that. So if you've got like a $350k mortgage at 6%, you're looking at roughly $1,678 before taxes and insurance kick in. Some lenders let you switch things up after—biweekly payments, different dates, whatever. Worth asking about because that extra payment per year thing actually does help you pay down the principal faster if you set it up right.

Paying it is pretty straightforward. Most people do it online or set up autopay so they don't have to think about when is first mortgage payment due after closing ever again. You can call, mail a check if you're old school, but honestly autopay is the move. Just make sure if you're doing something custom like biweekly stuff, you coordinate directly with your lender so it actually credits right.

Pro tip: if you miss a payment, it's not instant foreclosure or anything, but it'll definitely mess with your credit. Late is usually 15 days after due date depending on your lender. If you're struggling, just talk to them about partial payments or working something out. They'd rather work with you than deal with the headache.
