A credit score that is too low for a mortgage usually means too low for one specific program, at one specific lender, not for every option on the market. The gap between those options can run to thousands of dollars a year. Consider a borrower with a 600 score buying a $300,000 home. Under one set of assumptions, an FHA loan costs about $400 a month less than a conventional loan with mortgage insurance, and a nine-month credit-improvement wait lands somewhere in between. The worked numbers are in strategy 2 and the side-by-side comparison below.
Each of the seven strategies below attacks a different part of the problem: the score itself, the program, the lender, the file around the score, and the timeline. Duane Buziak works as an independent broker who lays those options out together, because Don’t Guess Your Rate. Shop It. applies even when credit is the obstacle.

1. Pull Your Actual Scores and Find the Real Cutoff for Each Program
There is no single national cutoff. Mortgage underwriting uses the middle score of three bureau scores, using older mortgage-specific scoring models, and each program sets its own floor. Free app scores often use different models, so they can differ by 20 points or more from what a mortgage file shows.
Here is an illustration. A borrower sees 641 on a consumer app. The mortgage-version scores come back at 652, 618, and 611, so the middle score is 618. That one number moves the borrower from “conventional looks fine” to “conventional is a stretch, FHA is clearly open.”
- Pull your free reports from annualcreditreport.com, the federally authorized source, and read every tradeline for accounts you do not recognize, wrong balances, and late payments that are not yours.
- Dispute errors directly with the bureau. The CFPB’s credit report guidance explains how disputes work.
- Ask Duane Buziak for a soft credit pull mortgage review. A soft pull mortgage broker can see your mortgage-relevant scores and map them to program minimums with no credit hit mortgage application.
The common mistake is trusting the free app number and applying to a program with a higher minimum. A decline you did not need to take can also lead you to assume you are shut out everywhere.
Measure two things: your middle score against each program’s minimum, and the number of programs you qualify for. Both are expected to change as you work through the rest of this list.
2. Use an FHA Loan to Qualify With a Lower Score
FHA loans are insured by the government, so the program tolerates weaker credit. Under HUD Handbook 4000.1, a 580 score or higher qualifies for the minimum 3.5% down payment, and scores of 500 to 579 require 10% down. Individual brokers and lenders may set higher floors (see strategy 4). The trade-off is mortgage insurance premium (MIP): an upfront premium of 1.75% of the base loan, plus an annual premium. As of this writing, HUD’s standard annual rate for a 30-year loan of this size with under 5% down is 0.55%. Confirm current rates in the handbook, since they can change.
Worked illustration: 600 score, $300,000 home
The rates below are assumptions for illustration, not quotes. Check current market averages through Freddie Mac’s Primary Mortgage Market Survey. Property tax and homeowners insurance are left out because they are roughly the same under every path; add your county’s rate from its assessor’s page.
- FHA, 3.5% down: $10,500 down, base loan $289,500. Upfront MIP of $5,066.25 is financed, so the loan is $294,566.25. At an assumed 6.50% for 30 years, principal and interest is about $1,862. Annual MIP of 0.55% on $289,500 is $1,592.25 a year, or $132.69 a month. Total: about $1,995 a month.
- Conventional, 5% down, if approved at 600: $15,000 down, loan $285,000. At an assumed 7.25% (low scores are priced higher), principal and interest is about $1,944. Assume private mortgage insurance of 1.9% a year, which is $451 a month. Total: about $2,396 a month.
Over five years, that gap is about $24,000 in favor of FHA. The pitfall is MIP duration. With less than 10% down, FHA mortgage insurance lasts for the life of the loan, while conventional PMI can be removed on request once the balance reaches 80% of the original value. On a $300,000 home, that threshold is a $240,000 balance. The usual exit is refinancing into a conventional loan once your score and equity allow it.
Measure the total monthly payment and the five-year cost including MIP, not the rate alone.
3. Fix the Specific Items Dragging the Score Down Before You Apply
Start with the mistake: closing old cards or opening new credit in the middle of a mortgage process. Closing a card shrinks your available credit and can push utilization up, and shortens your average account age. New accounts add inquiries and new debt that underwriting must explain. Leave the file alone while you work on it.
Revolving utilization, meaning balances as a percentage of limits, is often the fastest lever because it has no memory beyond the last reported statement. Suppose a card has a $10,000 limit and a $9,000 balance, which is 90%. Paying down $6,100 brings it to $2,900, which is 29%. If that card is the main drag on the score, the borrower may move into a better pricing tier.
Late payments and collections are slower. Errors can be disputed. Accurate items mostly need time, and some collections are better left to a broker’s guidance than paid blindly.
- List every account with balance, limit, and payment history.
- Pay revolving balances toward under 30% utilization, and lower if you can.
- File disputes on anything inaccurate, and keep copies.
- Once balances are paid, ask your broker about rapid rescore. Through a mortgage broker, the bureaus can update the file with proof of the payoff in days rather than waiting for the next monthly reporting cycle. Consumers cannot order it directly.
Measure the utilization percentage on each card and overall, then the middle score before and after the rescore.
4. Compare Hundreds of Wholesale Lenders Because Overlays Vary
Agencies and HUD publish the baseline rules. Individual lenders then add overlays, stricter internal rules such as a higher minimum score, tighter debt limits, or extra reserves. That is why the same file can be approved at one lender and declined at the next.
An illustration: one lender requires 640 on FHA, another follows the 580 baseline. A borrower at 612 is declined by the first and approved by the second, with the same income, the same assets, and the same home. A single retail lender can show only its own overlays. A broker with access to hundreds of wholesale lenders can route the file to one whose rules fit it.
The common mistake is applying to one retail lender, getting declined, and concluding that no one will lend. The second misconception is that shopping wrecks your credit. Hard inquiries from mortgage shopping within a short window are typically treated as one inquiry by scoring models, as the CFPB explains in its consumer guidance. A soft pull intake avoids the question at the start.
- Do one intake with Duane Buziak. A no hard inquiry mortgage pre approval step lets him review your scores without a mark on your report.
- Have offers priced from several qualifying lenders within the same rate-shopping window so that rates are comparable.
- Compare the Loan Estimates line by line: rate, APR, lender fees, and mortgage insurance.
Measure the number of approvals and the spread in rate and fees across them. A wide spread is where the savings are.
5. Add a Co-Borrower or Strengthen Compensating Factors
Automated underwriting does not look at the score alone. It weighs the full file, so strength in other areas can offset a weak score where program guidelines permit. Compensating factors include cash reserves after closing, a low debt-to-income ratio (DTI), a stable employment history, and a larger down payment. Fannie Mae’s Selling Guide describes how its underwriting engine evaluates these risk layers, and FHA treats them similarly in the HUD handbook.
An illustration: a borrower with a score near the edge has six months of reserves and a 36% DTI. The automated findings come back as an approval where the same score with 45% DTI and no reserves would not.
- Calculate DTI: total monthly debts including the new payment, divided by gross monthly income.
- Document reserves with two months of statements, and keep large deposits explained.
- If adding a co-borrower, run the scenario both ways. Some files improve, some do not.
The common mistake is adding a co-borrower with weaker credit or heavy debt. Most programs use the lowest middle score among borrowers, and added debt raises DTI, so the file can get worse.
Measure DTI, months of reserves, and the automated underwriting findings on each scenario.
6. Use Down Payment Assistance Programs Alongside a Lower-Score Loan
A low score often comes with thin savings. Down payment assistance (DPA) addresses the cash side of the problem, not the credit side. Duane Buziak offers Dynamo and Turbo DPA, which can reduce the cash a borrower needs at closing when paired with an eligible loan. Terms, structure, and repayment features change, so verify current details before relying on a figure.
An illustration: on the $300,000 FHA purchase from strategy 2, the 3.5% down payment is $10,500. If DPA covers most of that, cash to close drops sharply, and the borrower’s savings can go toward reserves, which also strengthen the file under strategy 5.
- Check eligibility with Duane Buziak, including the DPA program’s own score floor.
- Pair the assistance with the loan that fits your score, usually FHA or conventional.
- Get cash to close in writing with and without DPA.
The common mistake is assuming DPA waives credit requirements. It does not, and the assistance sits on top of the loan’s own rules and the investor’s overlays.
Measure cash to close before and after assistance, and your reserves after closing.
7. Consider Non-QM or a Planned Wait When Agency Loans Don’t Fit
If agency loans really do not fit, two routes remain. Non-QM loans fall outside standard qualified-mortgage rules and can use alternative documentation or tolerate credit events, but they cost more. The other route is a planned improvement period of 6 to 12 months with a specific score target.
Weigh them with numbers. Say a 9-month wait costs $18,000 in rent ($2,000 a month, illustrative). If the higher score moves the borrower from the 7.25% conventional scenario to an assumed 6.75% with lighter PMI (about 0.7%), the payment on a $285,000 loan falls from about $2,396 to roughly $2,015 a month. That is about $380 saved monthly, though FHA in strategy 2 already comes in near $1,995. A wait mostly makes sense when it unlocks PMI that can later be cancelled, at 80% of original value or $240,000 on this home.
- Price non-QM and agency options now.
- Set a score target and a date, and track the plan monthly.
- If you buy with higher-cost financing, plan the refinance up front.
The common mistake is accepting a high non-QM rate with no refinance plan. Suppose refinancing costs $6,000 and saves $250 a month: the break-even is 24 months. Measure the break-even months and the monthly payment difference.
The 600-Score Scenario Side by Side
These figures reuse the illustrative assumptions above for the same $300,000 home. They are not quotes, and they exclude taxes and insurance.
- FHA now (3.5% down): assumed 6.50% rate, about $1,995 a month including MIP, $10,500 down, MIP is lifelong at this down payment, refinance later is the exit.
- Conventional now (5% down, if approved): assumed 7.25% rate, about $2,396 a month including PMI, $15,000 down, PMI removable at an $240,000 balance.
- Wait nine months, then conventional (5% down): assumed 6.75% rate, about $2,015 a month including PMI, $15,000 down, about $18,000 in rent during the wait (illustrative), PMI removable.
Where to Start: Scores First, Then Quick Wins, Then Program Paths
Pull your real scores first and take a soft-pull comparison with Duane Buziak, because every other decision depends on knowing your middle score. Fix the quick-win items next, which usually means revolving balances and clear errors. Then compare FHA, conventional, and DPA paths against the same file, and keep non-QM or a planned wait for the cases where those do not fit.
