You calculated the down payment and thought you were ready, but closing costs typically run 2–5% of the purchase price. That's $6,000–$20,000 on a $400,000 home for appraisal fees, title insurance, origination fees, and attorney costs. Ask your lender for a Closing Disclosure at least three days before closing so you can see the exact breakdown. Many buyers are blindsided by fees they didn't anticipate and don't have enough cash on hand to cover them.
