Patrick's Quick Answer
AnnualCreditReport.com is the government-authorized source where you pull your full credit reports from Equifax, Experian and TransUnion for free. It does not give you a three-digit number. What it gives you is the raw data Lawrence the Loan Officer uses to calculate your mortgage scores. Check it weekly, spot the errors, and dispute them before they suppress your numbers.
The credit score on your phone is entertainment. AnnualCreditReport.com is the real thing. If you want to know what a mortgage lender is actually going to see, stop staring at the app and start here. This is the government-authorized Big Kahuna of credit reporting, and it is free.
What you actually get
Pull your reports there and you will not get a score. There is no three-digit number anywhere on those free reports. You get the actual lines: every account, every balance, every late payment, every inquiry, every collection, exactly as the bureaus hold them. That is the raw data Lawrence feeds into the scoring model when he runs your pre-approval pull. When a client tells me their app says 740 and my pull comes in lower, this is where the difference gets explained.
Check it weekly
My advice is to pull all three reports weekly while you are in the months before buying. Your report does not change that fast, but errors do not fix themselves. A paid collection that never dropped off, a closed account that still shows a balance, a tradeline that is not yours: all of it silently drags your numbers down. Spot it, dispute it, and give the dispute time to clear before the score actually matters.
Dispute before they suppress your numbers
The reason to start early is simple. When the underwriting pull happens, Ursula works from whatever is on those reports, and a dispute filed at the last minute is a problem sitting on your file while the clock runs. A dispute you file months out gets resolved before Lawrence ever runs the real pull. The reports are free, the disputes are free, and the payoff is a score that reflects what is actually true about you.
Reality Bites
The app on your phone is built to advertise credit products, and its number is not the score mortgage lenders use. The bureaus' raw reports have no agenda. Read them like facts: pull all three, compare them, and fix what is wrong before you need the number.
Patriot Pro Tip
Do not pay for your credit reports, and do not hand a random website your card number for a "free" score. AnnualCreditReport.com is the one the government authorized. Put a recurring reminder on your calendar and give each report a five-minute scan every month for anything new, anything closed that should not be, and anything that is not yours.
Checking your own reports is exactly the kind of groundwork I walk first-time buyers through in my free live webinar, alongside the rest of the financial foundation: debt-to-income, down payment, and how much house you can realistically afford in San Antonio and the Texas Hill Country. If you want a hand going through your reports line by line, that is a conversation worth having.
