Conventional Loan

Quick Definition

A conventional loan is any mortgage not insured or guaranteed by a federal government agency. Unlike FHA loans (backed by the Federal Housing Administration), VA loans (backed by the Department of Veterans Affairs), or USDA loans, conventional loans are offered by private lenders — banks, credit unions, and mortgage companies — and sold to Fannie Mae or Freddie Mac on the secondary market. They are the most common type of mortgage in the United States, representing about two-thirds of all home purchase loans.

What It Means

When most people imagine a standard mortgage, they are imagining a conventional loan. It is the "default" path for home financing, offered to borrowers who meet standard creditworthiness requirements. The lender takes on the risk (or transfers it to investors via the secondary market), and borrowers must qualify based on their credit score, income, debt levels, and down payment.

Because there is no government backing, conventional loans set their own standards. However, most conventional loans follow guidelines set by Fannie Mae and Freddie Mac to be eligible for sale on the secondary market — these are called "conforming loans."

Conventional Loan vs. Government-Backed Loans

Conforming vs. Non-Conforming Conventional Loans

Not all conventional loans are the same:

Conforming loans typically offer lower interest rates because they can be sold to Fannie Mae and Freddie Mac, creating liquidity for the lender.

Qualifying for a Conventional Loan

Credit Score Requirements

A single 40-point difference in credit score (700 vs. 740) can cost 0.25-0.50% in rate, translating to tens of thousands of dollars over a 30-year mortgage.

Debt-to-Income Ratio (DTI)

Lenders calculate your DTI to ensure you can afford the payment:

DTI = Total Monthly Debt Payments / Gross Monthly Income

Example: Monthly income $7,000, existing debts $300/month, proposed mortgage $1,400/month

• Total monthly obligations: $1,700
• DTI: $1,700 / $7,000 = 24.3% — easily approved

Down Payment Requirements

Private Mortgage Insurance (PMI)

When a conventional loan down payment is less than 20%, PMI is required. Unlike FHA's mortgage insurance premium, PMI on conventional loans is cancelable once equity reaches 20%.

PMI cancellation: Under the Homeowners Protection Act, PMI must be automatically cancelled when your LTV reaches 78% based on the original amortization schedule. You can request cancellation at 80% if you have a good payment history.

PMI cost example on $300,000 loan at 5% down:

• Loan amount: $285,000
• PMI rate: 0.85%
• Annual PMI cost: $2,423
• Monthly PMI: $202
• Months until 20% equity at normal payment: approximately 87 months (7+ years)

Conventional Loan Interest Rates: What Affects Them

Your rate is not a single number — it is determined by a matrix of factors:

Example: Rate difference by credit score on a $300,000 loan

Fixed-Rate vs. Adjustable-Rate Conventional Loans

Conventional loans come in fixed-rate and adjustable-rate varieties:

The Conventional Loan Process

1. Pre-approval: Lender reviews credit, income, assets; issues conditional approval
2. Home search: Shop with pre-approval letter in hand
3. Offer accepted: Contract signed; earnest money deposited
4. Loan application: Full application submitted with documentation
5. Appraisal: Independent value assessment of the property
6. Underwriting: Lender verifies all information and issues final approval
7. Clear to close: All conditions satisfied
8. Closing: Sign documents, pay closing costs, receive keys

Key Points to Remember

• Conventional loans are not government-backed — they are private loans with private risk
• Most conventional loans are conforming (following Fannie/Freddie guidelines) with a 2024 limit of $766,550
• Credit score has an enormous impact on rate — a 100-point difference can cost over $70,000 over 30 years
• PMI is required when down payment is below 20%, but unlike FHA, it is cancelable at 20% equity
• Conventional loans offer more flexibility than FHA on property condition and usage
• For buyers with 20%+ down and 720+ credit scores, conventional is almost always the best loan choice

Frequently Asked Questions

Q: Is a conventional loan better than an FHA loan? A: For buyers with good credit (680+) and at least 5% down, conventional is usually better because: PMI is cancelable (FHA MIP often lasts the life of the loan), no mandatory mortgage insurance with 20% down, and more flexibility on property types. FHA is often better for buyers with lower credit scores (580-640), limited down payment, or higher DTI ratios.

Q: What is the minimum down payment for a conventional loan? A: 3% for qualifying borrowers through Fannie Mae HomeReady or Freddie Mac Home Possible programs. Standard minimum is typically 5%. First-time homebuyers may access 3% down products more easily. However, putting down less than 20% triggers PMI.

Q: Can I use gift funds for a conventional loan down payment? A: Yes, with documentation. Fannie Mae and Freddie Mac allow gift funds from family members for down payments on primary residences. You will need a gift letter stating the funds are a gift (not a loan) and documentation of the transfer.

Q: How long does conventional loan approval take? A: The full process from application to closing typically takes 30-60 days, though some lenders can move faster (21-30 days) with complete documentation. Pre-approval is faster — often 1-3 business days.
