You beat out three other offers, the inspection came back clean, and your lender just told you the magic words: clear to close.
Then a new number lands in your inbox, one nobody mentioned in the Zillow listing.
The average American buyer pays roughly $6,000 in closing costs on a single-family home, according to data tracked by CoreLogic.
On a $400,000 mortgage that can run closer to $9,000 or $10,000 once title insurance, taxes, and lender fees stack up.
It's real money, and it's due in cash on the day you sign.
Here's the part that trips people up: closing costs are not one fee.
They're a pile of them, and some are negotiable, some are shoppable, and some you can't dodge no matter how hard you push.
The biggest line items are usually lender origination fees, appraisal, credit report, title search and title insurance, prepaid property taxes, homeowners insurance, and recording fees to your county.
There's also the escrow setup, where your lender collects a few months of taxes and insurance upfront so your future monthly payment covers them without a surprise shortage.
Where buyers get burned is at the Loan Estimate versus the Closing Disclosure.
Federal rules require your lender to send the Loan Estimate within three business days of your application, and the Closing Disclosure at least three business days before closing.
Certain fees can't legally increase, some can rise up to 10 percent, and others can change freely.
If a number jumped without a good reason, you have three days to ask questions, and you should use every one of them.
First, ask your lender for a list of which fees are shoppable, because title insurance and settlement services often are.
Second, ask the seller to cover a percentage of closing costs in your offer, especially in a market where homes are sitting longer.
Third, if you're refinancing instead of buying, know that refis carry their own closing costs, often 2 to 5 percent of the loan amount, and a no-cost refinance usually means a higher rate baked in.
Some lenders charge for "courier," "email," or "processing" that can sometimes be negotiated down or waived.
And pay attention to whether your loan includes discount points, since one point costs 1 percent of the loan and only makes sense if you plan to stay long enough to break even.
Closing costs are due by wire or cashier's check at settlement, and wiring instructions are a favorite target for scammers.
Always verify wire details by phone using a number you looked up yourself, never one from an email.
One more thing people forget: closing costs aren't just a buyer problem.
Sellers pay commissions, title transfer taxes, and often a portion of the buyer's fees.
That's why a good agent negotiates both sides.
Get the Loan Estimate early, compare it against the Closing Disclosure, question every increase, and ask what's shoppable.

A few phone calls and a sharp eye can easily save you a thousand dollars or more on the biggest purchase of your life.
