What is a Conventional Mortgage?
A conventional mortgage is a residential home loan that is not backed or insured by a government agency (such as the Federal Housing Administration, Department of Veterans Affairs, or USDA). Instead, conventional loans follow standard underwriting guidelines set by government-sponsored enterprises (GSEs): Fannie Mae (Federal National Mortgage Association) and Freddie Mac (Federal Home Loan Mortgage Corporation).
Because they are conforming to GSE standards, conventional loans can be bought and sold on the secondary mortgage market, keeping interest rates competitive and lending terms standardized across the United States.
Primary Advantage: Cancellable PMI
Unlike FHA loans where mortgage insurance premiums (MIP) usually stay for the entire loan life if putting down less than 10%, conventional Private Mortgage Insurance (PMI) is automatically eliminated once your principal balance drops to 78% of the original purchase price or appraised value.
Key Eligibility Requirements for 2026
To qualify for a conventional loan, lenders evaluate four key pillars of your financial profile:
1. Credit Score Benchmarks
- 620 Minimum Score: The baseline qualifying score for most conventional fixed-rate loan programs.
- 680–719 Tier: Moderate interest rates and reasonable private mortgage insurance premiums.
- 740+ Tier: Unlocks top-tier pricing, lowest interest rates, and minimal monthly PMI rates.
2. Down Payment Flexibility
- 3% Down Payment: Available through special programs like Fannie Mae HomeReady® and Freddie Mac Home Possible® for eligible first-time homebuyers or low-to-moderate-income earners.
- 5% Down Payment: The standard minimum down payment for single-family primary residence conventional purchases.
- 10%–15% Down Payment: Common for second homes or multi-unit properties.
- 20% Down Payment: Eliminates Private Mortgage Insurance (PMI) entirely from day one.
3. Debt-to-Income Ratio (DTI)
Your debt-to-income (DTI) ratio measures your monthly minimum debt payments (credit cards, auto loans, student loans, plus new housing payment) relative to your gross monthly income. Most conventional loans look for a maximum DTI between 36% and 45%, though Automated Underwriting Systems (Fannie Mae Desktop Underwriter® / Freddie Mac Loan Product Advisor®) may approve DTIs up to 50% with compensating factors like strong credit or cash reserves.
4. Employment and Income Stability
Lenders typically require a documented 2-year history of steady employment or continuous income in the same line of work, verified via W-2 statements, recent pay stubs, or two years of tax returns for self-employed borrowers.
Pros and Cons of a Conventional Loan
Advantages
- PMI can be cancelled: Disappears at 80%/78% LTV without refinancing.
- No upfront funding fees: Avoids FHA's 1.75% upfront fee.
- High loan limits: Up to $766,550+ for single-family homes.
- All property types: Primary residences, second vacation homes, and investment properties.
- Lower overall lifetime cost: Especially with credit scores above 700.
Considerations
- Stricter credit requirements: 620 minimum vs 580 for FHA loans.
- Higher PMI for lower credit: PMI costs increase significantly if credit is under 680.
- Tighter DTI thresholds: Less flexibility for high consumer debt than government loans.

Frequently Asked Questions
What is the minimum down payment for a conventional loan?
First-time homebuyers and eligible low-to-moderate-income borrowers can qualify for conventional financing with as little as 3% down through Fannie Mae HomeReady or Freddie Mac Home Possible programs. Standard conventional loans require a 5% down payment.
How do I get rid of PMI on my conventional mortgage?
Under the Homeowners Protection Act of 1998, you can submit a written request to cancel PMI once your principal balance reaches 80% of original value (via scheduled payments or extra principal reduction). Furthermore, your loan servicer is legally required to automatically cancel PMI when your balance reaches 78% LTV, provided your payments are current.
Can I use gift funds for a conventional down payment?
Yes! On a primary single-family home purchase, 100% of your down payment and closing costs can come from an eligible gift from a family member or eligible relative, provided a signed gift letter and bank paper trail confirming transfer of funds are documented.
Can I buy an investment property or vacation home with a conventional loan?
Yes. Conventional loans are one of the few standard programs that allow financing for second homes (vacation residences) starting at 10% down and 1-4 unit residential investment properties starting at 15%-25% down.
