Conventional Loans Explained: When They Beat FHA and How to Qualify

What Is a Conventional Loan?

A conventional mortgage is any home loan that is not backed by a federal government agency like the FHA, VA, or USDA. Conventional loans are originated by private lenders — banks, credit unions, and mortgage companies — and the majority are sold to Fannie Mae or Freddie Mac on the secondary market, which sets the underwriting standards for these loans.

Conventional loans account for approximately two-thirds of all U.S. home purchase mortgages and are particularly popular among buyers with good credit and stable employment. In Illinois in 2026, conventional loans are the dominant product for buyers with 620+ credit scores, and they're almost always the right choice for anyone with a score above 720 who has adequate savings for a down payment.

Qualification Requirements

Credit Score

The absolute minimum credit score for a conventional loan through most lenders is 620. But this is just the entry point — conventional loan pricing is highly sensitive to credit score. Rates and PMI costs improve significantly at each credit tier:

• 780+: Best rates, lowest LLPAs and PMI costs
• 760–779: Excellent rates, very low PMI
• 720–759: Very good rates, low PMI
• 680–719: Good rates; FHA comparison worth running
• 640–679: Rates are noticeably higher; FHA often competitive
• 620–639: Available but expensive; FHA is often better value

Income and Employment

Conventional lenders want to see:

• Two years of consistent employment history (same employer or same industry)
• Stable or increasing income — declining income raises flags
• Self-employed borrowers typically need two years of tax returns showing sufficient net income
• W-2 employees need recent pay stubs and two years of W-2s

Debt-to-Income Ratio (DTI)

Conventional guidelines allow a maximum back-end DTI of 45% through standard automated underwriting, and up to 50% in some cases with strong compensating factors (high credit score, significant reserves, low LTV). The front-end ratio (housing costs only) is typically not the binding constraint for conventional loans — it's the total DTI that matters.

Assets and Reserves

Beyond the down payment and closing costs, conventional lenders may require documented cash reserves — typically 2–6 months of mortgage payments held in savings or investment accounts. Reserves are more strictly evaluated for borrowers with lower credit scores or higher DTI ratios.

Down Payment Options

Conventional loans offer more down payment flexibility than many buyers realize:

• 3% down: Available through Fannie Mae's HomeReady and Freddie Mac's Home Possible programs for first-time buyers or low-to-moderate income borrowers. Income limits apply.
• 5% down: Standard minimum for repeat buyers or those not qualifying for 3% programs
• 10% down: Eliminates most PMI rate tiers; often better than FHA for 720+ credit buyers
• 20% down: Eliminates PMI entirely from day one; usually the most cost-efficient if achievable

How PMI Works — and When It Ends

Private mortgage insurance (PMI) is required on conventional loans when the down payment is less than 20% — which means the initial loan-to-value (LTV) ratio exceeds 80%. Unlike FHA's mortgage insurance, conventional PMI is not permanent and has three paths to cancellation:

1. Automatic cancellation: Under the Homeowners Protection Act, lenders must automatically cancel PMI when the loan balance reaches 78% of the original purchase price (based on your initial amortization schedule), provided you're current on payments.
2. Requested cancellation: Once your loan balance reaches 80% of the original appraised value, you can request PMI cancellation. You'll need to demonstrate that the loan balance is at or below 80% based on original value and that you have a good payment history.
3. Accelerated cancellation via appreciation: If your home has appreciated significantly, you may be able to refinance or request a new appraisal that shows current value, potentially eliminating PMI sooner. Most lenders require 24 months of seasoning before allowing cancellation based on appreciated value.

PMI Cost Ranges

Conventional PMI costs vary based on credit score, LTV, and loan term. Approximate annual rates:

Credit Score	5% Down (95% LTV)	10% Down (90% LTV)	15% Down (85% LTV)
760+	0.20–0.40%	0.15–0.30%	0.10–0.20%
720–759	0.40–0.70%	0.25–0.45%	0.15–0.30%
680–719	0.70–1.10%	0.45–0.70%	0.30–0.50%
620–679	1.00–1.50%	0.70–1.10%	0.50–0.80%

Rates are approximate ranges. Actual PMI will depend on specific lender, loan term, and current market conditions.

2026 Conforming Loan Limit: $832,750

For 2026, Fannie Mae and Freddie Mac set the baseline conforming loan limit at $832,750 for a single-family home in most U.S. counties. This is the maximum loan amount that qualifies for standard conventional financing. Loans above this threshold become jumbo loans, which have different requirements and pricing.

The $832,750 limit is well above the median home price in most Illinois markets, meaning the vast majority of home purchases in the state can be financed with a conventional conforming loan. For buyers looking at higher-priced properties in markets like Naperville, Lake Forest, or the North Shore, the jumbo threshold starts right around the price points where conventional loans no longer apply.

When Conventional Beats FHA: The Critical Analysis

The FHA vs. conventional decision shouldn't be made by rule of thumb — it requires calculating the actual total cost over your expected time in the home. That said, there are clear scenarios where conventional wins:

Conventional is Usually Better When:

• Credit score 720+: At this level, conventional rates are competitive and PMI costs are low — especially compared to FHA's permanent MIP structure
• Down payment 10%+: The higher your down payment, the more FHA's 1.75% upfront MIP hurts by comparison
• Long time horizon (5+ years): Because conventional PMI cancels at 80% LTV, you stop paying it — FHA MIP continues
• Loan above $541,287: FHA's Illinois limit is $541,287 in 2026; above this, conventional or jumbo are your only options
• Property condition concerns: If the property has issues that might not meet FHA standards, conventional avoids property condition complications

FHA is Usually Better When:

• Credit score 580–679: FHA is more accessible and often cheaper at lower credit tiers
• Very limited savings: 3.5% down and fully giftable provides earlier access to homeownership
• Recent credit events (bankruptcy, foreclosure): Shorter waiting periods
• High debt-to-income ratio: FHA's more flexible DTI guidelines allow qualification where conventional doesn't

FHA vs. Conventional: Side-by-Side Comparison

Property standards	HUD Minimum Property Standards	Standard appraisal; less restrictive
Gift funds	100% of down payment OK	Restrictions at low LTV

After foreclosure	3 years	7 years
Best fit	Credit 580–719, limited savings	Credit 720+, 10%+ down

How to Qualify for a Conventional Loan

The steps to conventional loan qualification are straightforward — but the details matter, especially for borrowers on the cusp of qualification thresholds:

1. Know your credit score: Check all three bureaus (Equifax, Experian, TransUnion). Lenders use the middle score. If your score is 610–619, it may be worth 30–60 days of credit optimization to cross the 620 threshold — or the 720 threshold, where pricing improves dramatically.
2. Calculate your DTI: Add up all monthly debt payments (car, student loans, credit cards, other) and divide by your gross monthly income. Aim for below 43%.
3. Verify your assets: Document your down payment and closing cost funds. Lenders need to see 60 days of bank statements for all accounts.
4. Work with a broker: Different lenders have different overlays and pricing. A broker can match your profile to the lender most likely to give you the best terms.
5. Get pre-approved: A full pre-approval with credit pull and income verification gives you the strongest buying position.
