Key Definitions

Here are the key terms you'll encounter when exploring conventional loans:

Conforming Loan
A conventional mortgage that conforms to Fannie Mae and Freddie Mac guidelines, including mortgage loan limits. Current limit: $806,500 for 1-unit homes.
Non-Conforming Loan (Jumbo)
A conventional mortgage that exceeds conforming loan limits, typically requiring higher credit scores and larger down payments.
Private Mortgage Insurance (PMI)
Insurance required when your down payment is less than 20%, protecting the lender if you default.
Debt-to-Income Ratio (DTI)
The percentage of your gross monthly income that goes toward debt payments. Conventional loans typically require DTI below 43% unless you have compensating factors like high equity or excellent credit.
Loan-to-Value Ratio (LTV)
The ratio of your loan amount to the home's appraised value. Lower LTVs often mean better rates and no PMI.
Pre-approval
A lender's conditional commitment to loan you a specific amount based on your financial information and credit check.

What is a Conventional Mortgage?

A conventional mortgage is a home loan that is not insured or guaranteed by the federal government. Instead, these loans are backed by private lenders and follow guidelines set by government-sponsored enterprises (GSEs) like Fannie Mae and Freddie Mac.

Unlike government-backed loans (FHA, VA, USDA), conventional mortgages rely on private capital and the borrower's financial strength. This means lenders can offer more flexible terms, but they also require stronger qualifications from borrowers.

How Conventional Mortgages Work

Conventional mortgages operate through a secondary market system where loans are sold to investors after origination. Here's the process:

  1. Origination: A lender approves and funds your mortgage
  2. Sale to GSEs: The lender sells your loan to Fannie Mae or Freddie Mac
  3. Securitization: Your loan is bundled with others into mortgage-backed securities
  4. Investor Purchase: Investors buy these securities, providing capital for new loans

This system allows lenders to offer competitive rates while managing risk through standardized guidelines.

When Conventional Loans Make Sense

Conventional loans work best for borrowers with good credit and stable income. Here's how it worked for one buyer:

Sarah had been renting for five years when she decided it was time to buy her first home. With a credit score of 720 and $15,000 saved for a down payment, she felt ready to take the plunge. Her stable job as a marketing manager provided the income she needed, and she was looking at homes well within the conventional loan limits.

Conventional mortgages work best for borrowers like Sarah who have good credit scores (typically 620 or higher) and can afford a down payment between 3% and 20%. These loans often offer flexibility that government-backed options may not provide, especially when it comes to avoiding lifetime mortgage insurance.

Sarah's situation was well-suited for a conventional loan. She had stable employment, a solid credit history, and enough savings for a 5% down payment. The fact that she could eventually remove her private mortgage insurance (PMI) once she reached 20% equity was a major advantage compared to FHA loans, which require lifetime mortgage insurance.

However, conventional loans aren't the right choice for everyone. If your credit score is below 620 , you might want to consider an FHA loan instead. Veterans should explore VA loans, which offer 0% down payment options. If you're buying in a rural area, USDA loans might be more suitable. And if you need to borrow more than $806,500 , you'll need to look into jumbo loans.

For Sarah, the conventional loan worked well. She closed on her three-bedroom townhouse last month and is already planning her first backyard barbecue. "The process went smoothly, and knowing I can remove the PMI in a few years makes the monthly payment much more manageable," she says. "I'm glad I waited until my credit was strong enough to qualify for a conventional loan."

What To Do If...

My credit score is low

You're not alone. Many first-time buyers start with credit challenges. The good news is that credit scores often improve with focused effort. While conventional loans require a 620 credit score, you may have several paths forward.

I have a high debt-to-income ratio

High debt-to-income ratios are one of the most common barriers to conventional loan approval. Lenders want to see that you can comfortably handle your mortgage payment alongside existing debts. The conventional loan limit is 43% , but there may be ways to improve your ratio.

Calculate Your Current DTI

  1. Add up all monthly debt payments (credit cards, car loans, student loans)
  2. Divide by your gross monthly income
  3. Multiply by 100 to get your percentage

4 Ways To Lower Your DTI

Four practical steps to reduce your debt-to-income ratio:

Reduce insuranceShop for rates, raise deductibles, bundle policiesLower payments cut DTI

Specific loan programs for people with high debt-to-income

Some loan programs allow higher debt-to-income ratios:

  • HomeReady: 50% DTI limit
  • Home Possible: 50% DTI limit
  • FHA: 56.9% DTI limit
I don't have money for a down payment

Saving for a down payment can feel overwhelming, but you won't need 20% down to buy a home. Designated conventional mortgage programs allow buyers to make down payments of just 3 percent. Many buyers use a combination of savings, gift funds, and down payment assistance to make homeownership possible.

Combining Multiple Sources

You can often combine different types of assistance. Community Seconds® is Fannie Mae's framework for pairing conventional mortgages with approved down payment assistance programs, allowing you to borrow up to 105% combined loan-to-value.

Alternative Sources for Down Payment

If traditional home buyer assistance programs aren't available to you, these options may help you save for a down payment:
