Conventional Loans: The Complete Guide for 2026
A practical, data‑driven walkthrough of the most common mortgage product on the market, with up‑to‑date rates, costs, and how to qualify in today’s environment.
1. What Is a Conventional Loan?
A conventional loan is a mortgage that is not insured or guaranteed by the federal government. In 2026, the two primary conventional categories are:
- Conforming: Meets the loan‑limit set by the Federal Housing Finance Agency (FHFA). For most of the continental U.S., the 2026 limit is $832,750; higher in high‑cost areas (up to $1,249,125 in San Francisco, New York, etc.).
- Non‑conforming (Jumbo): Anything above the conforming ceiling. Jumbo loans are priced separately and often require tighter credit.
Because they are sold to Fannie Mae and Freddie Mac, conforming loans follow strict underwriting standards—most notably the 20/1/2 rule: 20 % down, a credit score of 620 or higher, and a debt‑to‑income (DTI) ratio of 45 % or less.
2. 2026 Rate Landscape
As of August 2026, the average 30‑year fixed‑rate for a conventional loan sits at 6.75 %. Rates vary based on loan‑to‑value (LTV) and credit profile:
| Credit Score | LTV ≤ 80 % | LTV 80‑90 % | LTV 90‑95 % |
|---|---|---|---|
| 720‑740 | 6.50 % | 6.75 % | 7.00 % |
| 680‑719 | 6.75 % | 7.00 % | 7.25 % |
| 620‑679 | 7.00 % | 7.25 % | 7.50 % |
The spread between a 20 % down payment and a 5 % down payment can be as much as 0.75 percentage points, translating to roughly $1,350 in annual interest on a $300,000 loan.
3. Qualification Checklist
- Credit Score: Minimum 620 for most lenders; 740+ unlocks the best rates.
- Down Payment: 3 %–20 % for primary residences. 20 % eliminates private mortgage insurance (PMI).
- Debt‑to‑Income Ratio: ≤ 45 % (including projected mortgage payment). Some “high‑credit” borrowers can qualify up to 50 %.
- Employment History: At least two years of stable employment or consistent self‑employment income.
- Reserve Requirements: Lenders often ask for 2‑3 months of cash reserves after closing for conventional loans.
4. Cost Breakdown – What You’ll Pay
Below is a sample amortization for a $300,000 conforming loan with a 6.75 % interest rate and a 30‑year term. Numbers are rounded for clarity.
| Item | Amount |
|---|---|
| Loan Amount (30 yr @6.75 %) | $300,000 |
| Monthly Principal & Interest | $1,944 |
| Estimated Property Tax (1.2 %) | $300 |
| Homeowners Insurance | $100 |
| PMI (0.5 % of loan) | $125 |
| Total Monthly Payment | $2,469 |
If you can put 20 % down, the PMI line disappears and the total monthly payment drops to roughly $2,344, a $125 saving each month ($1,500 annually). That simple trade‑off is why many buyers aim for the 20 % threshold.
5. Conventional vs. FHA, VA, & USDA
The table below highlights the key differences that matter to a borrower in 2026.
| Feature | Conventional | FHA | VA | USDA |
|---|---|---|---|---|
| Min. Down Payment | 3 % (non‑prime 5 %) | 3.5 % | 0 % | 0 % |
| Mortgage Insurance | PMI until 20 % equity | MIP (upfront + annual) | No MIP | No MIP |
| Credit Score Floor | 620 | 580 | 620 (often lower) | 640 |
| Property Types | Single‑family, condo, townhome | Single‑family, 2‑unit | Single‑family, condo, townhouse | Rural single‑family, 2‑unit, manufactured |
If you qualify for VA or USDA and meet the location/servicing criteria, those programs can be cheaper because they eliminate mortgage insurance. However, they come with occupancy and eligibility rules that don’t apply to conventional loans.

7. Bottom Line
Conventional mortgages remain the most flexible and widely available product in 2026. They reward strong credit and larger down payments with lower rates and no ongoing mortgage insurance. If you can meet the 20 % equity threshold, you’ll enjoy the most cost‑effective financing on the market. When you’re below that line, weigh the extra PMI cost against the cash you keep for emergencies, renovations, or investing.
Use the calculator, review your credit report, and consider a modest increase in your down payment to eliminate PMI. The savings over the life of the loan can be tens of thousands of dollars—hardly “fluff” in a data‑driven world.
Frequently Asked Questions
Can I refinance a conventional loan into an FHA or VA loan?
Yes, you can refinance into a government‑backed loan if you become eligible (e.g., you join the military or purchase a qualifying rural property). Keep in mind that you’ll incur an upfront funding fee and new closing costs, which must be weighed against the potential rate reduction.
How does PMI cancel automatically?
Most lenders automatically terminate PMI once your LTV reaches 78 % based on the original amortization schedule, provided you are current on payments. You can also request early cancellation at 80 % LTV by submitting a written request and an appraisal.
Are conventional loans still available for first‑time buyers?
Absolutely. First‑time buyers can qualify with as little as 3 % down, though they’ll need to meet the DTI and reserve requirements. Many lenders offer special “first‑time buyer” programs that lower the required credit score to 640.
What happens if my loan amount exceeds the conforming limit?
You’ll be placed in the “jumbo” category. Jumbo loans typically have slightly higher rates (often +0.25 % to +0.50 %) and stricter documentation. However, many jumbo products now accept 10 % down with competitive pricing.
