Your credit score decides more than whether a lender says yes. It sets your rate and your mortgage insurance, and it is often the first thing a property manager checks on a rental application. How the score is built, what changed in 2025 and 2026 (rent can count now), how to fix what is holding it down, and who in Chicago helps for free.
By The Boulevard Group at Fulton Grace Realty, licensed Chicago real estate brokers, not credit experts. Gathered from the sources named in each section and reviewed October 2026.
We are real estate agents. We are not lenders, credit counselors, financial advisors or attorneys, and nothing in this guide is advice for your situation. We gathered it from the sources named at the end of each section (FICO, the credit bureaus, Fannie Mae, HUD, the FHFA, the CFPB and the FTC) and checked it as of October 2026. Scoring models, loan rules and laws change, and lenders apply them differently, so confirm anything you plan to act on with your lender, a HUD-approved housing counselor, or the source itself.
A credit score is a three-digit summary of your credit reports: the records Equifax, Experian and TransUnion keep on how you have handled borrowed money. Most scores run from 300 to 850. The score never sees your income, your savings or your job; a lender weighs those separately.
There is no single “your score.” Two companies build the scoring models, FICO and VantageScore, each has several versions, and each version reads each of the three reports. That is why the number in your banking app is often not the number a mortgage lender sees. For a mortgage, the lender usually pulls a score from all three bureaus and uses the middle one. Buying with someone else? Lenders typically take each buyer’s middle score and go by the lowest of them; Fannie Mae averages the buyers’ middle scores only to check its minimum on some loans underwritten by hand. Your lender can tell you which score it will use for you.
Scores matter before you buy, too. Property managers screen rental applications on credit. In our experience in Chicago, a score around 650 or better is a common bar, but that is what we see, not a published rule: each property manager sets its own. The same habits that open a mortgage open an apartment.
Sources for this section: myFICO (score ranges and models); the Fannie Mae Selling Guide, B3-5.1-02 (which score a mortgage uses). The 650 figure is our own experience with Chicago rentals.
FICO publishes the recipe for its scores in five categories. These are the weights for the general population:
| Category | Weight | What it reads |
|---|---|---|
| Payment history | 35% | Whether you paid on time, and any late payments, collections or bankruptcies. One 30-day late can cost a strong score real points. |
| Amounts owed | 30% | Mostly how much of your card limits you are using (utilization), overall and card by card. Carrying a balance is not the problem; using most of your limit is. |
| Length of history | 15% | The age of your oldest account, your newest, and the average. A long history helps but is not required for a good score. |
| New credit | 10% | Recent applications (hard inquiries) and newly opened accounts. Several in a short stretch reads as risk. |
| Credit mix | 10% | Cards alongside installment loans like a car or student loan. Nobody needs one of each. |
FICO’s own caveat, and ours: these are averages, and the weights shift from person to person. A short credit history is scored differently from a long one, so the same late payment can cost one person far more than another.
VantageScore 4.0 is now accepted on mortgages sold to Fannie Mae and Freddie Mac (more on that below). Its weights look similar, with payment history even heavier:
| Factor | Weight |
|---|---|
| Payment history | 41% |
| Depth of credit (age and mix) | 20% |
| Credit utilization | 20% |
| Recent credit | 11% |
| Balances | 6% |
| Available credit | 2% |
Three differences matter for renters and first-time buyers. VantageScore 4.0 counts rent and utility payments when they appear on your reports, it ignores paid collections and medical collections, and it can score people with very short histories that older models cannot score at all.
Card balances and errors. Paying balances down shows up as soon as the next statement reports, often within a month. A corrected error usually lands within about 30 days of a dispute. Payment history is the slow lever: every on-time month helps, and old late payments fade. These are typical timelines, not promises; how much any one change moves your score depends on the rest of your file.
Sources for this section: myFICO (the FICO weights); Chase (the VantageScore 4.0 weights); VantageScore (how VantageScore 4.0 treats rent and collections); the CFPB, on disputes (dispute timelines).
Since September 2026, every approved lender selling loans to Fannie Mae and Freddie Mac can use VantageScore 4.0 instead of Classic FICO, the older score mortgages have long run on. VantageScore counts rent payments that reach your credit reports; Classic FICO does not. HUD has announced that FHA will adopt VantageScore 4.0 and FICO 10T as well. Ask your lender which score it pulls.
Fannie Mae’s underwriting can credit 12 months of on-time rent of $300 or more, read from your bank statements with your permission. Through May 2026, more than 21,000 mortgage applications got a better result that way, and a missed rent payment is not held against you in that check.
Since November 2025, loans run through Fannie Mae’s Desktop Underwriter have no minimum credit score; the system weighs the whole file instead. Loans underwritten by hand still need 620 for a fixed rate and 640 for an adjustable one, and any lender can set a higher floor of its own.
Illinois law has barred the credit bureaus from reporting medical debt since 2025. Nationally, the bureaus already leave off paid medical collections and any under $500. A federal rule that would have removed all medical debt from reports was struck down in court in July 2025, and federal regulators have since argued that federal law overrides state rules like Illinois’, a question no court has settled. We are not attorneys and cannot tell you how this applies to a particular bill; legal aid or a consumer attorney can. Either way, a dispute costs nothing: if a medical bill appears on your report, dispute it.

These rules were changing through 2025 and 2026; check the current version with your lender.
| On your report | How long it stays |
|---|---|
| Late payments (30 days or more) | 7 years from the original missed payment |
| Collections | 7 years from the original delinquency |
| Chapter 7 bankruptcy | 10 years from filing |
| Chapter 13 bankruptcy | 7 years from filing |
| Hard inquiries | 2 years on the report; FICO counts them for 1 |
| Closed accounts paid as agreed | Up to 10 years (these help you) |
The weight of a negative item fades long before it drops off. A late payment from four years ago costs far less than one from last spring, which is why the most valuable thing you can do after a rough stretch is a long run of on-time months.

AnnualCreditReport.com gives you a free report from each bureau every week, permanently. It is the only official site; look-alikes charge you or fish for your information. Checking your own credit never lowers your score.
An account that is not yours, a balance that is off, a late payment you did not make, a debt listed twice, medical debt. Dispute with the bureau showing it (online, or by certified mail with copies of your proof) and with the company that reported it. They generally have 30 days to investigate, and a correction must reach all three bureaus. Not fixed? File a complaint with the CFPB. An account you never opened is identity theft: report it at IdentityTheft.gov.
Bring anything past due current first, then set every account to pay at least the minimum automatically. On-time from here forward is the biggest lever you have over time.
Under 30% of your limits is the common rule, and single digits score best, both overall and card by card. Card issuers usually report the balance on your statement date, so pay before the statement closes, not just before the due date. That one change can lift a score within a cycle even if you already pay in full every month.
Within 30 days of a debt collector’s first notice, you can ask it in writing to prove the debt, and it has to pause collecting until it does. Before you pay, get any agreement in writing; some collectors will agree to remove the account when it is paid, many will not. Newer scores ignore paid collections, Classic FICO still counts them, and some loan programs require collections to be paid before closing, so ask your lender which ones matter for your loan.
One late payment on an otherwise clean account? A short, polite letter asking the lender to remove it as a courtesy sometimes works. No law requires a lender to say yes, and many will not. Disputing an accurate late payment will not remove it; asking nicely sometimes does.
Closing an old no-fee card shortens your history and shrinks your available credit, which raises utilization. Put a small charge on it now and then, paid off, so the issuer keeps it active.
Watch the same score each month (many banks and card apps show one free). Expect balance changes to show in 30 to 60 days, disputes in about 30 to 45, and recovery from late payments over months.
If your situation is complicated (debts in collection, a bankruptcy, identity theft, or a lawsuit), a HUD-approved housing counselor or a nonprofit credit counselor is a better guide than we are. Both are listed under Who can help, below.

No history at all can hold you back as much as a bruised one. Each of these reports to the bureaus, which is the whole point:
You put down a deposit, say $500, and it becomes your limit. Use it lightly, pay it in full, and many issuers graduate you to a regular card.
Offered by credit unions and some banks: the loan sits in savings while you make small payments, usually over 6 to 24 months, and then the money is yours.
Someone you trust adds you to a long-standing card with a low balance and a spotless record. That card’s history can help yours. Pick the card carefully: its missed payments would show up on your report too.
If your property manager offers rent reporting, opt in. If not, services such as Esusu and Self can report rent to all three bureaus, and some can add up to 24 months of past payments, usually for a fee. We have not used these services ourselves and do not recommend one over another; read the fees and how to cancel before you sign up. Reported rent counts in VantageScore 4.0 and in newer FICO versions, which is where mortgages are heading.
Experian Boost adds utility and streaming payments to your Experian file, and Experian itself notes that most mortgage lenders do not consider scores affected by Boost; it is more useful for renting and credit cards. Payday loans do not build credit at all, and “buy here, pay here” car lots often report only the late months.

What scores usually work, by program:
| Program | Credit score that usually works |
|---|---|
| Conventional, Fannie Mae automated approval | No set minimum since November 2025; pricing improves at each step up to 780 |
| Conventional, underwritten by hand | 620 for a fixed rate, 640 for an adjustable rate |
| FHA | 580 with 3.5% down; 500 to 579 with 10% down |
| VA | No VA-set minimum; each lender sets its own |
Months before you shop, not the week you find the place. A lender reads your actual reports and can show which fix would raise your score the most, which is often not the one you would guess.
No new accounts, no closing old ones, no co-signing, and no financing furniture until after closing. The file is checked again right before closing day.
Mortgage credit pulls inside a short window count as a single inquiry. Newer FICO versions allow 45 days, but the older versions many mortgage lenders still use allow 14, so keep your comparison shopping inside two weeks.
After you pay a balance down or get an error fixed, your lender can ask the bureaus for a rapid rescore, which usually takes 2 to 5 days instead of the month or two normal reporting takes. Only a lender can order one, and the lender cannot bill you for it directly.
Every lender adds its own requirements on top of these programs, so the score that works at one lender may not at another. The whole loan picture, from down payments to the 2026 limits, is in the financing guide.

Nonprofit credit counseling: the National Foundation for Credit Counseling (800-388-2227) connects you with a certified counselor at a member agency for a budget and debt review, and a debt management plan if you need one. Fees are modest and can be waived for hardship.
A credit repair company does what you can do yourself for free: dispute errors. It cannot remove accurate, current negative information, and no one can promise you a score.
The law is on your side. Under the federal Credit Repair Organizations Act, a company cannot take payment until the work is done, must give you a written contract with the total cost, and must let you cancel within three business days. In Illinois, credit services organizations also have to register with the Illinois Secretary of State and carry a $100,000 bond; ask for proof of both.
Walk away from: anyone who wants payment up front, promises to remove accurate items or reach a certain score, tells you not to contact the bureaus yourself, or suggests a “CPN” or any new number in place of your Social Security number. That last one is illegal.
Well-reviewed names, if you want help: CNBC Select’s October 2026 review picked Sky Blue Credit Repair (in business since 1989, with a 90-day money-back guarantee), Credit Saint (a 90-day refund if nothing is removed) and The Credit People (a low setup fee, and refunds if you see no progress). These are CNBC Select’s picks, not ours: we have not used or checked out these companies, and naming them here is not a recommendation. Expect a setup fee plus a monthly fee, most often $50 to $150 a month. The cautionary tale: in the CFPB’s case against Lexington Law and CreditRepair.com, a court found the companies broke federal law with illegal upfront fees, and refunds to their customers began in December 2024. We earn nothing from any company or agency on this page.

No. Your own checks, and the soft pulls behind prescreened offers, are invisible to the scores. Hard inquiries come from applying for credit, and FICO counts them for one year.
For a mortgage, conventional pricing improves at each step up to 780, where the best tier starts. For an apartment, in our experience many property managers look for around 650. Whatever the number today, the steps above move it; your lender can tell you the number that matters for your loan.
Pay them down, yes. Close them, usually no: an open card with a zero balance helps both your utilization and the age of your history.
It depends on the score. Newer FICO versions and VantageScore ignore paid collections, so paying can help there; Classic FICO still counts a paid collection. Your loan program may require it paid either way, so ask your lender before you pay.
Balances: a cycle or two. Errors: about a month. Late payments: they fade over months and years, and the fix is time plus on-time payments.
Pull the three reports and fix any errors, opt into rent reporting, keep card balances low, and talk with a lender once, early, so the plan fits the loan you will actually use. A year of on-time rent can help a Fannie Mae approval even before it shows in a score.
It is general information, gathered by real estate agents from the sources named in each section and checked as of October 2026. It is not financial, credit or legal advice, and we are not experts in credit. We may have missed a change since then, and your file is your own. Before you act on anything here, confirm it with your lender, a HUD-approved housing counselor (the CFPB’s finder is linked above) or the source itself.
We are glad to introduce you to lenders our clients have closed with. A lender can read your actual reports, show which fix moves your score the most, and set a timeline, at no cost and with no commitment. While you work on it, we keep the search going.
