Should You Close at the Start or End of the Month? The Smart Buyer's Guide to Saving Big

The Closing Date Dilemma: Why It’s More Than Just a Calendar Choice

You might think picking a closing date is all about convenience—maybe you’re juggling a lease, vacation plans, or a moving truck schedule. But there’s a twist that many first-time buyers don’t see coming: your closing date can change how much you pay out-of-pocket—by hundreds of dollars.

Yep. The date you sign those final papers isn’t just a formality—it affects how soon you pay your mortgage and how much cash you need at closing. Let’s decode it.

Mortgages Are Paid in Arrears, Not in Advance

Here’s a surprise for anyone used to paying rent: mortgages work differently.

While rent is typically due at the beginning of the month, a mortgage is paid after the fact. This means when you make your first mortgage payment, you’re covering the interest for the previous month—not the one you’re currently living in.

So if you close on May 2nd, your first mortgage payment won’t be due June 1st—it’ll be due July 1st, and it’ll cover the month of June. But there’s a catch...

What about the interest from May 2nd through May 31st? That’s where prepaid interest comes in.

What Is Prepaid Interest—and Why Does It Matter?

Prepaid interest is the daily interest on your loan, paid upfront at closing. It covers the gap between your closing date and the end of the month.

The math is simple: the earlier you close in the month, the more days of interest you prepay. The later you close, the fewer days you pay for.

• Close on May 2nd? That’s 29 days of prepaid interest.

• Close on May 30th? Just 1 or 2 days.

And yes, that makes a real difference to your wallet.

Real Numbers, Real Impact: How Timing Changes Costs

Let’s say you’re buying a $300,000 home with a 30-year fixed FHA loan. You’re putting 3.5% down, have a 720+ credit score, and qualify for a 6.5% interest rate.

Your loan amount would be about $289,500, with a daily interest of roughly $52.50/day.

• Close on May 2nd: You’ll pay around $1,470 in prepaid interest.

• Close on May 30th: Just $105.

That’s over $1,300 in difference, depending on your timing.

When you’re also budgeting for your down payment, moving costs, new furniture, or that dreamy backyard setup—you’ll want to know what to expect.

Which Closing Date Wins? It Depends on Your Strategy

There’s no one-size-fits-all answer. Here’s how the timing shakes out:

Closing Early in the Month:

• More prepaid interest, so higher upfront cost

• Your first mortgage payment is nearly two months away

• More buffer if there are delays in closing

• Helpful if you’re overlapping rent and want breathing room before payments begin

Closing Late in the Month:

• Lower prepaid interest, so less cash due at closing

• First mortgage payment still due July 1st (if closing in May)

• Less wiggle room—any delay can bump you into a new month

• End-of-month closings are popular, so title companies may be swamped

So What’s the Move?

If your goal is to minimize upfront costs, a late-month close could help ease the cash crunch.

If you’d rather have some space between your rent ending and your first mortgage payment, an early-month close gives you more time to adjust and regroup.

Either way, understanding how prepaid interest works puts you in control of your money—and your move.
