Everything US Homebuyers Need to Know About Mortgage Types

Why Mortgage Type Matters

Most buyers focus on interest rates and monthly payments, but the type of mortgage you choose shapes your costs, qualification requirements, and long-term financial exposure just as much. Different loan programs carry different rules about down payments, credit minimums, mortgage insurance, and eligible properties.

Before you shop for a home or compare lenders, understanding how each program works puts you in a much stronger position. This guide covers the four main government-backed and conventional mortgage categories available to US buyers. For a grounding in broader real estate vocabulary, see our glossary of housing market terms used throughout the buying process.

Conventional Loans: The Baseline Option

Conventional mortgages are not backed by a federal agency. Instead, they are issued by private lenders and typically conform to standards set by Fannie Mae and Freddie Mac — the government-sponsored enterprises that purchase mortgages on the secondary market. Loans that meet those standards are called conforming loans; those that exceed the conforming loan limit are jumbo loans (covered separately below).

Key Features

• Credit score: Most lenders require a minimum score of 620, though better rates generally require 740 or higher.
• Down payment: As low as 3% for qualifying first-time buyers, though 20% avoids private mortgage insurance (PMI).
• Private mortgage insurance (PMI): Required if your down payment is below 20%, but can be canceled once you reach 20% equity.
• Debt-to-income (DTI) ratio: Typically capped at 45%–50%, though lender guidelines vary.

Conventional loans offer the widest range of property types and terms, making them the most common mortgage for buyers with stable income and solid credit.

FHA Loans: Built for Lower Credit and Down Payments

Federal Housing Administration (FHA) loans are insured by the US Department of Housing and Urban Development (HUD). Because the federal government bears part of the default risk, lenders can offer these loans to borrowers who might not qualify for conventional financing.

Key Features

• Minimum credit score: 580 for a 3.5% down payment; 500–579 with 10% down (lender overlays may set higher minimums).
• Mortgage insurance premium (MIP): FHA loans require both an upfront MIP (typically 1.75% of the loan amount) and an annual MIP, regardless of down payment size. Unlike conventional PMI, annual MIP on most FHA loans issued after June 2013 with less than 10% down remains for the life of the loan.
• Loan limits: FHA sets county-level limits annually; they are generally lower than conforming loan limits in high-cost areas.
• Property standards: The home must meet FHA minimum property requirements.

FHA loans are accessible, but the long-term cost of mortgage insurance can be substantial. Run the numbers over the full loan term — not just the monthly payment — before deciding.

VA Loans: The Benefit for Military Borrowers

VA loans are guaranteed by the US Department of Veterans Affairs and are available to eligible active-duty service members, veterans, and surviving spouses. They are widely considered the most favorable mortgage program for those who qualify.

Key Features

• No down payment required for eligible borrowers in most cases.
• No private mortgage insurance: VA loans do not require PMI, which can represent significant monthly savings.
• VA funding fee: A one-time fee (typically 1.25%–3.3% of the loan amount, depending on down payment and use) replaces PMI. It can be financed into the loan. Some veterans with service-connected disabilities are exempt.
• Credit and income: The VA does not set a minimum credit score, but most lenders require at least 580–620.
• Occupancy: The property must be the borrower's primary residence.

VA loans can be used multiple times and, in some cases, simultaneously. Eligibility depends on your length and type of service; the VA's Certificate of Eligibility (COE) confirms your entitlement.

USDA Loans: Rural and Suburban Options

The US Department of Agriculture's Single Family Housing Guaranteed Loan Program supports homeownership in eligible rural and certain suburban areas. Despite the agency's name, USDA loans are not limited to farmland — many small towns and suburban communities qualify.

Key Features

• No down payment required for qualifying borrowers.
• Income limits: Household income generally cannot exceed 115% of the area median income (AMI); limits vary by location and household size.
• Guarantee fee: An upfront guarantee fee (currently 1% of the loan amount) and an annual fee (currently 0.35%) replace traditional mortgage insurance.
• Property location: Must be in a USDA-designated eligible area. The USDA provides an online eligibility map.
• Primary residence only: Investment properties and vacation homes do not qualify.

USDA loans are a genuinely underused option for buyers who assume they must live in a major metro area to afford a home without a large down payment.

Jumbo Loans and Non-Conforming Mortgages

When a loan amount exceeds the conforming loan limits set annually by the Federal Housing Finance Agency (FHFA), it becomes a jumbo loan. In 2024, the baseline conforming limit for most of the country is $766,550 for a single-unit property, with higher limits in designated high-cost areas.

Because Fannie Mae and Freddie Mac cannot purchase jumbo loans, lenders retain them on their own books — meaning stricter qualification standards apply:

• Credit scores typically must be 700 or higher, often 720+.
• Down payments commonly range from 10% to 20% or more.
• Reserve requirements (cash savings after closing) are often substantial.
• DTI ratios are usually held to 43% or below.

For buyers in high-cost markets, jumbo loans may be the only path to financing a purchase. Rates and terms vary considerably between lenders, so comparing multiple offers is especially important in this category. See our overview of fixed-rate vs. adjustable-rate mortgages to understand how rate structure interacts with loan size over time.

Choosing the Right Mortgage for Your Situation

No single mortgage type is universally better. The right choice depends on your credit profile, available cash, income, military status, where you plan to buy, and how long you expect to stay in the home.

Once you understand the landscape, the next steps involve getting pre-approved and formally entering the buying process. Our step-by-step home buying guide walks through what happens from pre-approval to closing. You may also want to understand the difference between pre-qualification and pre-approval before approaching a lender.

A licensed mortgage professional or HUD-approved housing counselor can help you compare total loan costs — not just rates — across the programs you may qualify for. Total cost analysis, including insurance, fees, and long-term interest, should always inform the final decision alongside the monthly payment figure.
