Understanding Jumbo Loans and Conventional Mortgages

In the world of home financing, mortgages can generally be divided into two broad categories: jumbo loans and conventional mortgages. While they may seem similar on the surface, there are key differences between these two loan types that borrowers should be aware of.

The Definition of a Jumbo Loan

A jumbo loan, as the name suggests, is a large mortgage loan that exceeds the conforming loan limits set by the Federal Housing Finance Agency (FHFA). These limits are established annually and vary by location, reflecting local real estate prices. Jumbo loans are considered non-conforming because they surpass these limits, and as a result, they are often subjected to stricter lending criteria. Lenders typically require higher credit scores, larger down payments, and more extensive documentation for jumbo loans, given the greater risk associated with lending a larger amount of money.

What Constitutes a Conventional Mortgage?

A conventional mortgage, on the other hand, is a home loan that adheres to the conforming loan limits set by the FHFA. By the same token, it meets the requirements of Fannie Mae and Freddie Mac. Conventional mortgages are available in various forms, including fixed-rate and adjustable-rate options, and often present fewer hurdles for borrowers compared to jumbo loans. 

The main advantage of a conventional mortgage is that it often comes with lower interest rates and more flexible terms, provided the borrower meets the standard credit and income requirements.

Jumbo Loans vs. Conventional Mortgages at a Glance

  • Jumbo Loans: Best suited for properties exceeding the conforming loan limit, often coming with stricter requirements but offering higher borrowing amounts. They are typically used for luxury homes or properties in high-priced areas.
  • Conventional Mortgages: Governed by the conforming loan limit and typically have less strict requirements than jumbo loans. They are widely available and might come with more competitive rates, especially for well-qualified borrowers.

Choosing between these two loan types depends largely on the property price, your financial standing, and your long-term goals. By understanding the distinctions and seeking expert advice, you can make an informed decision that supports your home ownership journey.

Loan Limits: The Key Difference

Perhaps the most prominent difference between jumbo loans and conventional mortgages lies in the loan limits. While conventional loans must comply with the preset conforming loan limit (which is set at $726,200 in 2023 by the FHFA), jumbo loans exceed these boundaries. The specific threshold for a jumbo loan varies by county and is typically higher in areas with a higher cost of living.

Because jumbo loans surpass the regulated limits, they do not benefit from the same governmental backing and protection that conventional loans do. This lack of support leads to higher risk for lenders and often translates into higher interest rates and more stringent qualification requirements for borrowers. Understanding the loan limits and how they impact the loan’s terms and conditions is essential for any prospective homebuyer, as it influences both the accessibility of the loan and its long-term cost.

Interest Rates and How They Compare

Interest rates play a crucial role in differentiating jumbo loans from conventional mortgages. Generally, jumbo loans carry higher interest rates than conventional loans due to the increased risk associated with lending a larger amount of money. Without the government backing that conventional loans receive, lenders are exposed to greater risk with jumbo loans, and they pass that cost onto the borrower in the form of higher interest rates. While the exact difference in rates can vary based on market conditions, lender policies, and borrower qualifications, it’s common for jumbo loans to have an interest rate that’s 0.25% to 0.5% higher than conventional mortgages.

Credit Requirements for Jumbo vs. Conventional Loans

Credit requirements also vary between jumbo loans and conventional mortgages. Since jumbo loans involve larger sums of money and are considered riskier, lenders typically require a higher credit score for approval. While a conventional mortgage might require a credit score of at least 620, jumbo loans often demand a score of 700 or higher. 

Furthermore, borrowers seeking a jumbo loan may face more rigorous scrutiny of their credit history, including a closer examination of payment patterns, outstanding debts, and overall financial stability. Meeting the credit requirements for a jumbo loan may be more challenging, particularly for borrowers with blemishes on their credit report.

Down Payment Differences

The down payment requirements for jumbo and conventional loans also diverge significantly. Conventional loans often allow for lower down payments, sometimes as low as 3%, especially for first-time homebuyers or those who qualify for specific programs. Jumbo loans, in contrast, typically require a larger down payment, often ranging from 10% to 20% or more of the purchase price. This larger initial investment reflects the lender’s need for additional security given the larger loan amount. Borrowers considering a jumbo loan should be prepared for a substantial upfront cost and ensure that they have the necessary funds available.

Understanding Underwriting Criteria

Underwriting criteria encompass the various factors that lenders consider when evaluating a loan application, and they differ between jumbo loans and conventional mortgages. For conventional loans, underwriting criteria are often standardized, reflecting the guidelines set by Fannie Mae and Freddie Mac. These might include evaluation of credit score, debt-to-income (DTI) ratio, employment history, and property appraisal.

Jumbo loans, on the other hand, may have more individualized underwriting criteria, reflecting your particular lender’s unique approach to risk assessment. This might include a more thorough analysis of financial reserves, a closer examination of the property’s value, and additional scrutiny of the borrower’s overall financial situation. Some lenders might also require two appraisals for a jumbo loan instead of one, adding another layer to the underwriting process.

Pros and Cons of Jumbo Loans


  • Access to Larger Amounts: Jumbo loans allow borrowers to access financing beyond conventional loan limits, enabling the purchase of higher-priced properties.
  • Flexible Terms: Some lenders offer more flexible terms and customized loan structures for jumbo loans, tailored to a borrower’s specific financial situation.
  • Potential for Competitive Rates: Borrowers with strong credit and financial standing may find competitive interest rates, depending on the lender.


  • Higher Interest Rates: Generally, jumbo loans may come with higher interest rates compared to conventional loans, reflecting the greater risk to the lender.
  • Stricter Requirements: Qualifying for a jumbo loan often requires a higher credit score, substantial down payment, and extensive documentation.
  • Limited Availability: While River Capital does offer jumbo loans, not all lenders do.

Pros and Cons of Conventional Mortgages


  • Wider Availability: Conventional mortgages are widely available through various lenders, offering more choices and competitive rates.
  • Lower Interest Rates: Typically, interest rates for conventional mortgages may be lower than jumbo loans, especially for borrowers with good credit.
  • Flexible Down Payment Options: With various programs and guidelines, borrowers might qualify for lower down payment requirements.


  • Loan Limits: Conventional loans are subject to conforming loan limits, restricting the amount you can borrow, which might not be suitable for higher-priced properties.
  • Stricter Property Requirements: Conventional loans often come with specific property appraisal and condition requirements, potentially limiting eligible properties.
  • Potential for Private Mortgage Insurance (PMI): Borrowers making a down payment of less than 20% on a conventional loan may be required to pay PMI, adding to the monthly payment.

Special Considerations for Borrowers

When choosing between a jumbo loan and a conventional mortgage, borrowers should consider several key factors. Understanding the total cost, including interest rates, fees, and potential PMI, is crucial. Evaluating personal financial readiness, including credit score, down payment capabilities, and long-term financial goals, will also play a vital role.

Special considerations may also include:

  • Market Conditions: Fluctuating interest rates and lender policies can impact both jumbo and conventional loan options.
  • Future Financial Plans: Consider how the loan aligns with future financial and lifestyle goals, such as potential relocation or changes in income.
  • Professional Guidance: Consulting with mortgage professionals, financial advisors, and real estate agents can help clarify options and align a loan choice with individual needs and market realities.

By weighing the pros and cons and considering these special factors, borrowers can make an informed decision that best aligns with their unique circumstances and homeownership aspirations.

How to Choose the Right Loan for You

Choosing between a jumbo loan and a conventional mortgage depends on both your personal financial situation and the property you’re interested in. Here are some guiding steps:

  • Evaluate Your Financial Status: Begin by taking an honest assessment of your financial health. Examine your credit score, monthly income, and the amount you can afford for a down payment.
  • Understand Property Prices: Familiarize yourself with property prices in your desired location. If most of the properties fall within the conventional loan limit, that type of loan might suffice. However, if you’re leaning towards luxury homes or properties in high-priced areas, a jumbo loan is likely to be more appropriate.
  • Consider Future Plans: Think about your long-term goals. If you plan to stay in the home for a long time, locking in a fixed-rate jumbo loan might make sense. However, if you see it as a short-term stay, the flexibility and lower interest of a conventional loan might be more appealing.
  • Consult a Mortgage Advisor: Before making a decision, speak to a trusted mortgage advisor who can offer insights specific to your situation. They can help evaluate your qualifications for each loan type and provide guidance on interest rates and potential future scenarios.
