Fixing Your Credit to Qualify for a Mortgage
May 28, 2026
The short version
The specific moves that actually shift a score in 60-180 days. No hype, no gimmicks.
Your credit score is not a verdict. It is a snapshot that responds to inputs.
The myth this page exists to kill
"My credit is too low. I'll never qualify."
Wrong. Most people who think their credit is permanently bad have a score that's fixable in 60-180 days with targeted, specific actions. The score is not a verdict. It's a snapshot that responds to inputs.
This page walks through what actually moves a FICO score, what doesn't, and the order to do things in. None of this is credit-repair-company nonsense. It's the boring, mechanical stuff that works.
What a FICO score actually is
The FICO score is a number from 300 to 850 that summarizes how likely you are to repay a loan, based on your past credit behavior. Higher = better. Mortgage lenders typically look at the middle of your three scores (from Experian, Equifax, and TransUnion).
The five factors and their approximate weight:
1.
Payment history (35%).
Have you paid your bills on time?
2.
Credit utilization (30%).
How much of your available credit are you using?
3.
Length of credit history (15%).
How long have your accounts been open?
4.
Credit mix (10%).
Do you have a mix of credit types (cards, installment loans, etc.)?
5.
New credit (10%).
Have you opened a lot of new accounts recently?
The top two factors (payment history and utilization) are 65% of your score. They're also the two you can move the fastest. That's where to focus.
Score thresholds that matter for mortgages
740+:
Best rates available. Access to every loan program.
680-739:
Good rates, slightly higher than the top tier. Most loan programs available.
620-679:
Conventional loans may have add-on fees or PMI cost penalties. FHA still works well.
580-619:
FHA still works at this range with 3.5% down. Conventional is mostly off the table.
Below 580:
Limited options. FHA technically allows down to 500 with 10% down, but most lenders won't actually do those loans. Move the score up before applying.
Most first-time buyers who think their score is "too low" are in the 580-680 range. That's not too low. That's eligible for FHA right now, and movable into the conventional zone in a few months with focused work.
The 60-day score moves (highest impact)
Move 1: Pay down credit card balances below 30% of the limit.
Credit utilization is 30% of your score, and the calculation is per-card AND aggregate. If you have a $5,000 limit card with a $2,500 balance, that card is at 50% utilization, which hurts your score. Pay it down to under $1,500 (30%) and your score will jump on the next reporting cycle. Pay it down to under $500 (10%) and you'll get the biggest boost.
The reporting cycle: card companies report your balance to the credit bureaus once a month, typically at the end of your statement period. So if you pay down your card on the 5th but the bureau already received the high balance on the 1st, your score won't reflect the paydown until next month's cycle.
If you have cash to do this, this is the single fastest score-boosting move you can make.
Move 2: Don't close old credit cards.
Closing an old card shortens your average credit history AND reduces your total available credit (which raises your utilization ratio on the same balance). Both hurt your score. Even if you don't use a card anymore, keep it open with a $0 or minimal balance.
Move 3: Don't open new credit accounts.
Each new credit application creates a hard inquiry, which dings your score by a few points. Multiple inquiries in a short window dings it more. Mortgage inquiries within a 14-day window count as one for scoring purposes, but other credit (new car loan, store credit card, furniture financing) all add up.
If you're 60-90 days from applying for a mortgage, don't open any new accounts. Don't even apply for the 10% discount from the home goods store.
Move 4: Make every payment on time. Every one.
Set up autopay for at least the minimum on every debt. A single 30-day-late payment can drop your score 50-100 points and stays on your report for 7 years. The minimum payment counts as on-time for credit reporting purposes.
Move 5: Pull your reports, dispute errors.
Pull all three reports for free at annualcreditreport.com. Look for:
- Accounts you don't recognize (could be identity theft)
- Late payments you actually made on time
- Accounts showing higher balances than you have
- Collections from accounts you've already paid
Each major credit bureau has an online dispute portal. The process takes 30-45 days. Successful disputes can move a score 20-80 points depending on the error.
The 90-180 day moves (mid-term)
Pay off collections strategically.
Old unpaid collections can drag a score down even when nothing else is wrong. The strategy depends on the age and the collector:
- If the collection is recent (less than 2 years) and from a major creditor, paying it off helps.
- If the collection is old (4+ years) and from a debt buyer, paying it can actually RESET the clock on your report and hurt your score. In that case, talk to a credit counselor before paying.
- "Pay for delete" is a strategy where you negotiate the collector removing the entry from your report in exchange for payment. Some collectors will do this; some won't. Get the agreement in writing BEFORE paying.
Become an authorized user on someone else's good account.
If you have a family member with a long-standing, well-managed credit card, ask to be added as an authorized user. The card's history (length + utilization + payment record) becomes part of your credit file. This can move a thin-file score by 20-50 points in 30-60 days. You don't have to actually use the card.
Get a secured credit card.
If you have very little credit history (a "thin file"), a secured credit card with a small limit ($300-$500) used responsibly will build payment history quickly. Use it for one small recurring charge (gas, a streaming subscription) and autopay the full balance every month.
Don't pay debt off in a way that increases utilization on remaining cards.
This is counterintuitive. If you have $5,000 across three cards and you pay off one card completely, the remaining $5,000 is now spread across two cards instead of three. Your aggregate utilization went up unless you also closed the paid-off card (which you shouldn't, per Move 2). Distribute paydown evenly across cards, or focus on the highest-utilization card first.
The longer-term moves (6-12 months)
Build a payment history on installment debt.
If you have only credit cards (revolving debt) and no installment loans, adding a small installment loan (auto loan, small personal loan) can improve your credit mix and your score. Don't take on debt just for this purpose. But if you were going to finance something anyway, this is a side benefit.
Let time work.
Many of the worst score drops (late payments, collections, bankruptcies) age off after a defined period:
- Late payments: 7 years
- Collections: 7 years
- Chapter 7 bankruptcy: 10 years
- Chapter 13 bankruptcy: 7 years
- Hard inquiries: 2 years
If your bad-credit episode was 5+ years ago, much of the damage has already started to fade. Keep doing the right things and time will continue to help.
What does NOT work (the credit-repair scam category)
"Credit repair" companies that charge $100/month to "fix" your credit.
Most of them do what you could do for free: dispute every negative item with the bureaus and hope something falls off. There's no secret method. If a company tells you they can remove accurate negative items, they're lying. If they tell you to create a new identity (CPN, EIN substitute, etc.), they're suggesting fraud and you could go to prison.
"Credit privacy numbers (CPNs)."
Illegal. Don't.
"Authorized user trading lines for sale."
Pay $500 to be added as an authorized user on a stranger's card with great history. Underwriters increasingly detect and discount these. Risky and shady.
"Rapid rescore" for $100.
Pay your lender to expedite reporting of changes you've already made (paying down a card). This one can be legitimate if you've actually made the underlying change. But it doesn't create score improvement out of nothing.
If you're tempted by any of the above, the answer is: do the boring stuff in this article, give it 60-180 days, and you'll get there without the scam tax.
A 90-day plan to add 50-80 points
If you're starting at, say, 620 and want to get to 680 or 700:
Days 1-7:
- Pull all 3 credit reports
- List every debt with current balance, limit, and minimum payment
- Identify errors and dispute them online
Days 8-30:
- Pay down each credit card to under 30% utilization (priority on highest-utilization cards first)
- Set up autopay for the minimum on everything
- Ask a family member with strong credit to add you as authorized user
Days 31-60:
- Continue paying down cards toward 10% utilization on each
- Don't open any new credit
- Check disputed items for resolution; re-dispute if necessary
Days 61-90:
- Re-pull your credit report and score
- If score moved enough, apply for pre-approval
- If score didn't move enough, identify the specific reason (still high utilization? unresolved dispute? unpaid collection?) and address it
This works. It's not glamorous. It's mechanical. It moves the number.
Frequently asked
How long does it take to fix bad credit?
Significant improvement in 60-90 days for utilization-driven low scores. 6-12 months for scores held down by recent late payments. 2-5 years for scores held down by bankruptcies or major collections. Not forever, but not overnight either.
Will paying off a collection raise my score immediately?
Sometimes yes, sometimes no. Depends on the credit scoring model the lender uses, the age of the collection, and whether the collector reports the payment. Newer scoring models (FICO 9, FICO 10, VantageScore 4.0) ignore paid collections. Older models (FICO 8, which most mortgage lenders still use) still count them. Talk to your lender about which model they use before paying off a collection.
Should I close credit cards I don't use?
No. Keep them open with a $0 balance. Closing them shortens your credit history average and increases utilization on your remaining cards.
Can I qualify for a mortgage with a 580 credit score?
Yes, with FHA. The catch is finding a lender willing to do an FHA loan at 580. Many lenders have internal overlays that require 620 or higher even though FHA's official minimum is lower. Shop lenders.
What if I've never had credit?
Thin file. Get a secured credit card with a small limit, use it for one small recurring expense, autopay it for 6-12 months. That builds enough history to qualify for most loan programs.
