In one line: Everything paid at the closing table besides the price: lender, title, escrow, prepaids and taxes.
Closing costs are the fees settled when a sale records: the lender's origination and underwriting, the appraisal and credit report, the title policies, the escrow company's fee, recording fees, the transfer tax, and the prepaid first year of insurance and months of taxes into the escrow account.
A buyer's side on a financed purchase usually lands between 2% and 3% of the price on top of the down payment. In Southern Nevada the seller customarily pays the real property transfer tax and the owner's title policy, the buyer pays the lender's policy and lender fees, and the escrow fee is split; the contract can move any of it.
Every figure is itemised on the Loan Estimate at application and the Closing Disclosure three days before signing. The two should match; a line that grew is the question to ask.
A worked example
On a $450,000 financed purchase with 20% down, a buyer's closing costs land near $9,000 to $13,500: lender fees, the lender's title policy, half the escrow fee, recording, and a year of insurance plus a few months of taxes into escrow. The seller's side carries the $2,295 transfer tax and the owner's policy.
Questions people ask
How much are closing costs for a buyer in Las Vegas?
Usually 2% to 3% of the price on a financed purchase, on top of the down payment; less for cash. The Loan Estimate itemises them at application and the Closing Disclosure three days before signing.
Can closing costs be rolled into the loan?
Not directly on a purchase; the loan is capped by the appraised value. A lender credit in exchange for a slightly higher rate, or a seller concession negotiated in the contract, are the two ways to reduce the cash at closing.
