For most homebuyers, purchasing a property requires financing through a mortgage. Among the many options available, the conventional mortgage remains the most widely used. Unlike loans backed by government programs such as the FHA, VA, or USDA, a conventional mortgage is not insured by the government. Instead, it follows underwriting guidelines set by Fannie Mae and Freddie Mac, two government-sponsored enterprises (GSEs) that help stabilize the mortgage market.
In 2025, conventional mortgages continue to dominate residential real estate financing because they offer competitive rates and flexible terms for qualified borrowers. However, they also come with stricter requirements, making them less accessible to those with lower credit scores or smaller savings.
This guide explores what conventional mortgages are, how they work, and what buyers need to know when considering this type of loan.
What Is a Conventional Mortgage?
A conventional mortgage is a home loan that is not insured or guaranteed by a government agency. Instead, it is originated and serviced by private lenders but must conform to rules set by Fannie Mae and Freddie Mac for standardization and secondary market resale.
Key characteristics:
Not government-insured (unlike FHA, VA, or USDA loans).
Requires higher credit scores (often 620+ minimum).
Typically demands larger down payments (as low as 3% for some borrowers, but often 10–20%).
May require private mortgage insurance (PMI) if the down payment is under 20%.
Types of Conventional Mortgages
Conforming Loans
Meet Fannie Mae and Freddie Mac standards.
Subject to loan limits set annually (varies by county).
Non-Conforming Loans (Jumbo Loans)
Exceed conforming loan limits.
Typically used for luxury or high-value properties.
Stricter qualification requirements.
Advantages of Conventional Mortgages
Lower Costs Over Time: Competitive interest rates for strong borrowers.
Flexible Terms: Loan terms range from 10 to 30 years, fixed or adjustable.
No Upfront Insurance Premiums: Unlike FHA loans, which require upfront mortgage insurance.
Elimination of PMI: Borrowers can cancel private mortgage insurance once equity reaches 20%.
Investment Properties Eligible: Conventional loans can finance second homes or rental properties.
Disadvantages of Conventional Mortgages
Higher Credit Requirements: Generally require stronger credit histories.
Larger Down Payment: Often higher than FHA or USDA loans.
Tougher Approval Process: More stringent debt-to-income (DTI) ratio limits.
Less Accessible for First-Time Buyers: Can be challenging for buyers with limited savings.
