Conventional Loans: A Complete Guide
Conventional loans are the most widely used mortgages in the United States. Unlike FHA, VA, or USDA loans, they are not insured by a federal agency. Instead they follow underwriting guidelines set by Fannie Mae and Freddie Mac and are offered by banks, credit unions, and mortgage companies nationwide. Understanding conventional financing is the foundation of smart mortgage shopping, and at Coventry Enterprises LLC Loans we believe every borrower deserves a clear picture of how these loans work before committing.
Conforming vs. Non-Conforming Conventional Loans
A conforming loan meets the loan limits and credit guidelines set by Fannie Mae and Freddie Mac. In 2026 the baseline conforming loan limit is $806,500 for a single-family home in most counties. High-cost areas such as parts of California and New York have limits reaching up to $1,209,750. Because conforming loans can be sold to Fannie and Freddie, lenders price them competitively and offer them widely.
A non-conforming conventional loan, most often called a jumbo loan, exceeds the applicable conforming limit for the county. Lenders hold jumbo loans on their own books or sell them to private investors, resulting in stricter requirements and generally higher rates. If your loan amount exceeds the conforming limit in your area, expect more rigorous underwriting.
Down Payment Options
Conventional loans are available with as little as 3 percent down through Fannie Mae's HomeReady and Freddie Mac's Home Possible programs, both designed for low-to-moderate income buyers and first-time homeowners. A standard conventional loan requires 5 percent down. Putting down 20 percent eliminates private mortgage insurance entirely, which is one of the biggest financial advantages of a larger down payment and a key reason borrowers save toward that threshold.
Credit Score Requirements
A minimum credit score of 620 is the standard threshold. Borrowers with scores between 620 and 739 will qualify but pay higher rates and more expensive PMI. Scores of 740 or above access the best rates and the lowest PMI cost tiers. The credit score has a larger impact on conventional loan pricing than on most government-backed programs, so improving your score before applying can result in meaningful savings over the life of the loan.
Private Mortgage Insurance
PMI is required when the down payment is less than 20 percent. It typically costs 0.5 to 1.5 percent of the original loan amount per year, divided into monthly installments added to the mortgage payment. The key advantage over FHA mortgage insurance is that PMI on a conventional loan can be cancelled. Under the Homeowners Protection Act, lenders must cancel PMI automatically when the LTV reaches 78 percent based on the original purchase price. Borrowers can request cancellation at 80 percent LTV, sometimes requiring an appraisal to confirm current value if appreciation is being used to establish equity.
Debt-to-Income Ratio
Most conventional loan guidelines allow a maximum back-end DTI of 45 percent. Fannie Mae's Desktop Underwriter automated system can approve DTIs up to 50 percent for borrowers with compensating factors such as high credit scores, significant reserve assets, or larger down payments. The front-end ratio covering housing costs alone is viewed favorably at 28 percent or below, though it is the back-end DTI that most lenders scrutinize as the primary qualification metric.
Fixed-Rate vs. Adjustable-Rate Conventional Loans
Conventional loans come in both fixed and adjustable varieties. The 30-year fixed conventional mortgage is the most popular home loan in the country, providing payment certainty over a long horizon. A 15-year fixed builds equity faster and cuts total interest roughly in half at the cost of a higher monthly payment. Adjustable-rate conventional loans such as a 5/1 or 7/1 ARM offer a lower initial rate during the fixed period and may suit buyers planning to sell or refinance within that window. The choice between fixed and adjustable depends on your planned time horizon and tolerance for payment variability.
Employment and Income Documentation
Lenders require two years of employment history in the same field. W-2 employees provide recent pay stubs and two years of tax returns. Self-employed borrowers must provide two years of complete personal and business tax returns, a year-to-date profit and loss statement, and often business bank statements. Income stability matters as much as the current income amount when lenders evaluate conventional loan applications.
Property Requirements
The property must meet Fannie Mae or Freddie Mac guidelines. Conventional loans are available for primary residences, second homes, and investment properties, though down payment requirements, interest rates, and reserve requirements differ by occupancy type. Second homes typically require 10 percent down and investment properties 15 to 25 percent down. The property itself must appraise at or above the purchase price and meet general safety and structural standards.
Benefits of Conventional Loans
- No upfront mortgage insurance premium unlike FHA loans
- PMI can be cancelled once 20 percent equity is reached
- Available for primary residences, second homes, and investment properties
- Multiple term options from 10 to 30 years
- Competitive rates for borrowers with strong credit profiles
- No geographic restrictions or income limits unlike USDA loans
Drawbacks of Conventional Loans
- Higher minimum credit score than FHA loans
- PMI required with less than 20 percent down
- More difficult to qualify with high existing debt levels
- Less flexibility for non-traditional income documentation
- Property must meet standard appraisal requirements
Comparing Conventional to Government-Backed Loans
FHA loans allow lower credit scores (580 versus 620) and smaller down payments but charge mortgage insurance that lasts the life of the loan for most borrowers. VA loans offer zero down payment and no mortgage insurance for eligible veterans but require service eligibility. USDA loans offer zero down with low fees for eligible rural properties but have geographic and income limits. Conventional loans are available to the widest range of buyers without geographic restrictions and offer the most flexibility in property type and occupancy, making them the default choice for buyers who meet the qualification standards.
Common Mistakes to Avoid
Assuming PMI is permanent: Many borrowers do not realize PMI can be cancelled. Track your loan balance and home value so you can make the cancellation request when eligible and stop paying the premium.
Ignoring the loan limit: If your loan exceeds the conforming limit for your county, you need a jumbo loan with different requirements. Plan your purchase price with the local limit in mind.
Opening new credit before closing: New credit inquiries or accounts opened before closing can affect your score and jeopardize approval. Avoid all new borrowing until after the loan closes.
Choosing the wrong term: A 30-year loan minimizes monthly payments but maximizes total interest paid. A 15-year loan costs significantly less over time. Model both scenarios for your situation before deciding.
Underestimating closing costs: Conventional loans carry closing costs of 2 to 5 percent of the loan amount. Budget for these costs independently from your down payment funds.
When a Conventional Loan Makes Sense
A conventional loan is the right choice when you have a credit score of at least 620, manageable debt levels, and enough savings for at least a 3 percent down payment. If you can reach 20 percent down you eliminate PMI entirely and access the best rates. Conventional loans are the only option for second homes and investment properties since government-backed programs are restricted to primary residences. For buyers with strong credit who meet the conforming loan limits, conventional financing almost always offers the best overall terms available.
The team at Coventry Enterprises LLC Loans encourages every borrower to compare all available loan options before committing. The right mortgage is the one that matches your specific financial situation, credit profile, and long-term goals for the property.
