Plain-language guides on how credit scores actually work and how disputes get resolved.
Payment history and amounts owed together make up about two-thirds of a typical credit score. Length of credit history, new credit, and credit mix make up the rest. The single fastest lever most people overlook is credit utilization — the percentage of your available revolving credit you're using. Dropping utilization from 60% to under 30% can move a score meaningfully within a single reporting cycle, well before any dispute is filed. Disputes fix errors; utilization and on-time payments build the score underneath them.
Most negative items — late payments, collections, charge-offs — fall off seven years from the date of first delinquency, not from when the debt was sold or last updated. Chapter 7 bankruptcy stays up to ten years; hard inquiries drop after two. Debt collectors sometimes report an old debt with a new date to make it look more recent, which resets nothing legally but can trick an outdated system. Knowing the real removal date is often the fastest way to win a dispute, because bureaus are required to delete items once that date passes.
A soft inquiry happens when you check your own report, or a company checks it for a pre-approved offer — it's invisible to lenders and never affects your score. A hard inquiry happens when you formally apply for credit, and it can cost a few points and stays visible for two years. Rate-shopping for a mortgage or auto loan within a focused window is usually treated as a single inquiry by scoring models, so it's safe to compare a few offers back to back — spreading applications out over months is what adds up.
"Paying off a collection removes it" — not automatically; it may still show as paid until it ages off. "Closing old cards helps your score" — usually the opposite, since it shortens your credit history and raises utilization. "Credit repair companies can guarantee removals" — no legitimate company can guarantee an outcome, because deletion depends on whether the bureau or furnisher can verify the item, not on how the dispute is worded. Anyone who promises a specific result up front isn't being straight with you.
Pull all three bureau reports at least 90 days before you plan to apply — errors take time to resolve, and mortgage underwriting is unforgiving of last-minute changes. Don't open new credit or make large purchases on existing cards during that window; both can shift your utilization and debt-to-income numbers right when a lender is looking. If you find an error, dispute it early enough that a resolution letter, not just an open case, is on file by the time you apply.
Watch for accounts you didn't open, hard inquiries you don't recognize, a sudden address change, or a score drop with no obvious cause. Freezing your credit with all three bureaus is free and stops most new-account fraud outright — it doesn't affect your existing score. If you find a fraudulent account, file an FTC identity theft report first; it gives you a legal basis to have the account blocked, not just disputed, which moves faster than a standard dispute.
