If you have ever lain awake wondering "am I even allowed to do this," you are not behind. You are exactly on schedule. Almost nobody is taught how to buy a house. You were taught how to rent one, maybe, and that was it. So let's fix that right now, with the very first number that decides everything else: your credit score.
What a credit score actually is
A credit score is a three-digit number, somewhere between 300 and 850, that tells a lender how reliably you have paid back money you borrowed in the past. That's it. It isn't a grade on your worth as a person, and it isn't a mystery only banks can see. It is built from things like whether you pay bills on time, how much of your available credit you're using, and how long you've had accounts open.
Here is roughly how lenders read that number:
- 300 to 579 is considered Poor. Approval for most loans is hard here.
- 580 to 669 is Fair. You can qualify for some loans, often FHA ones, but rates are higher.
- 670 to 739 is Good. This is where most Americans sit, and most loan doors are open.
- 740 to 799 is Very Good. Lenders treat you as low risk and offer better rates.
- 800 to 850 is Exceptional. You get the best terms available.
You do not need to be in the top tier to start. You need to know, honestly, where you stand today.
How to check it yourself, free, without hurting your score
This is the part that gets hidden from people on purpose. AnnualCreditReport.com is the only website authorized by federal law to give you free credit reports from all three credit bureaus: Equifax, Experian, and TransUnion. Since September 2023, that free access became permanent, and you can pull a report from each bureau once every single week if you want to, at no cost.
A quick but important distinction: your credit report is the full history (accounts, payment record, balances). Your credit score is the number calculated from that history. AnnualCreditReport.com gives you the reports. Some banks and card apps will also show you a version of your score for free as a courtesy.
One more thing that stops people cold: checking your own score this way is called a "soft pull." It does not lower your score, no matter how many times you look. The score only takes a small, temporary dip when a lender pulls it because you're formally applying for new credit (a "hard pull"), and we'll cover how to manage that safely in Level 4.
Debt-to-income: the second number nobody explains
Once a lender knows your credit score, they look at your debt-to-income ratio, usually shortened to DTI. It's simpler than it sounds: DTI is your monthly debt payments divided by your gross (before-tax) monthly income.
Lenders actually look at two versions of this number:
- Front-end DTI counts only your future housing payment (mortgage, taxes, insurance) against your income. Lenders like to see this at or below roughly 28%.
- Back-end DTI counts all your monthly debts, including the new house payment: car loans, student loans, credit cards, the works. Many lenders prefer this at or below 36%, and most conventional and FHA loans can still work up to around 43%, with some approvals stretching higher for strong borrowers using automated underwriting.
None of these are hard walls carved in stone everywhere. They're guardrails. A lower DTI simply means more lenders compete for your business, and you get to pick, instead of hoping one says yes.
How much house your income really carries
Skip the internet rumors for a second and do simple math. Take your gross monthly income. A front-end DTI of 28% is your rough monthly housing budget ceiling. That housing payment includes principal, interest, property tax, homeowners insurance, and (if you have less than 20% down) mortgage insurance. It is never just "the mortgage." We'll build out every piece of that true monthly number in Level 2.
Renting versus buying, told honestly
Here is something almost nobody in this industry will say out loud, because nobody gets a commission from it: sometimes renting is the smarter move, at least for now. If you're likely to move again within two or three years, if closing costs and a slow market would eat any equity you'd build, or if buying would leave you with no safety cushion at all, renting can be the bold, disciplined choice. Boldness isn't "always buy." Boldness is "know the real math and choose on purpose." Run your own numbers with our rent-vs-buy calculator before you decide anything.
Walking in bold
You don't need a flawless score. You don't need to be debt-free. You need your two real numbers, checked yourself, for free, this week: your credit score and your debt-to-income ratio. Everyone you're about to meet, agents, lenders, sellers, already assumes you don't know these. Showing up already knowing them changes the entire conversation, before it even starts.
