Jumbo loan guide: How jumbo mortgages work

A jumbo loan is a conventional mortgage that lets you borrow more than the conforming loan limit for your county, so you can buy a higher-priced home with a single mortgage. Because you're borrowing more, jumbo loans typically cost more and have stricter eligibility requirements than conforming loans.

Learn more about 2026 loan limits, how a jumbo loan compares with a conventional loan, the types of jumbo loans available, the pros and cons, lender requirements, rates and closing costs, refinancing, and more.

Key takeaways:

• A jumbo loan is a conventional mortgage that exceeds the conforming loan limit set each year by the FHFA. This means your lender can’t sell it to Fannie Mae or  Freddie Mac, so it can set its own requirements.
• For 2026, the baseline conforming loan limit is $832,750 for a one-unit home in most counties, rising to $1,249,125 in high-cost areas, Alaska, Hawaii, Guam, and the U.S. Virgin Islands.
• Jumbo loans usually require a higher credit score, lower DTI, larger down payment, and more cash reserves than conforming loans.

What is a jumbo loan?

A jumbo loan, also known as a jumbo mortgage, is a conventional loan that exceeds the conforming loan limit set annually by the Federal Housing Finance Agency (FHFA).

As a nonconforming conventional loan, a jumbo loan cannot be sold to Fannie Mae or Freddie Mac. Lenders are free to set their own requirements for a jumbo loan and typically require a stronger credit profile, a lower debt-to-income ratio (DTI), and more cash reserves than for a conforming loan.

Jumbo loan limits in 2026

The baseline conforming loan limit for a one-unit home in 2026 is $832,750. In high-cost housing markets, plus Alaska, Hawaii, Guam, and the U.S. Virgin Islands, the limit increases to $1,249,125.

The limits also vary depending on the number of units in the home.

Limits vary by county. You can check the FHFA Conforming Loan Limit Values Map to see which value applies in a specific county.

Types of jumbo loans

Jumbo loans come in a few different repayment structures, much like conforming loans, so you can choose the option that fits your plans:

Fixed-rate jumbo loans

A fixed-rate jumbo loan keeps the same mortgage interest rate for the entire loan term, typically 15 or 30 years. Your principal and interest payment stays the same each month, which can make budgeting easier if you plan to stay in the home long term.

Adjustable-rate jumbo loans

An adjustable-rate jumbo loan, or jumbo ARM, starts with a fixed introductory rate for a set period, then adjusts periodically based on market conditions. The Jumbo Smart loan from Rocket Mortgage, for example, offers a 7/6 ARM with a 7-year fixed introductory rate followed by an adjustment every 6 months.

VA and FHA jumbo loans

VA loans have no limit for borrowers with full entitlement, but VA loans that exceed the conforming loan limit are often referred to as a VA jumbo loan.¹

FHA loans have a strict borrowing limit, but some loans on the higher end are referred to as an FHA jumbo loan.

Jumbo loan requirements

As a nonconforming loan, each lender sets its own standards for a jumbo loan. Common requirements for a jumbo loan include:

Property types

Whether you're expanding a real estate portfolio or building a custom retreat, a jumbo loan can typically finance:

• Vacation homes
• Investment properties
• Condos
• Multifamily homes
• New-construction homes

Down payment

Jumbo loans typically require a higher down payment than conforming loans. You'll usually need to put down at least 10%, though some lenders require 25% or 30%.

Your minimum will depend on your total loan amount, credit history, and type of housing. Lenders often require a larger down payment for a second home or a multifamily home.

With a Jumbo Smart loan from Rocket Mortgage, you'll need a down payment of at least 10%. A Home Loan Expert can help you determine your specific requirements before you start house hunting.

Credit score

Jumbo loans typically call for a stronger credit profile than conforming loans, and the exact credit score required varies by lender and loan terms.

With a Jumbo Smart loan from Rocket Mortgage, you'll need a credit score of at least 680, though the minimum can climb to 760 depending on the property type and interest rate type.

DTI

Your DTI measures how much of your monthly income goes toward debt payments. A lower DTI shows lenders you have more room in your budget to afford a mortgage payment.

Some lenders cap DTI at 43% for a jumbo loan, though a Jumbo Smart loan from Rocket Mortgage allows a DTI of up to 50%.

A higher down payment or credit score may help you qualify with a higher ratio.

Consistent income

Lenders want proof that your income is steady and likely to continue. Expect your lender to ask for your W-2s, tax returns, or 1099s from the past 2 years, along with additional documentation to confirm your income won't change after closing.

Cash reserves

Because jumbo loans involve larger balances, lenders want assurance that you can afford the payments even if your income is interrupted.

Expect your lender to ask for your bank statements proving you have 6 – 30 months of expenses in reserve, depending on your loan amount and lender.

Here are the cash reserve minimums for a Jumbo Smart loan from Rocket Mortgage:

• Loan amount of $1 million or less: 6 months
• Loan amount of $2,000,001 – $2,500,000: 12 months
• Loan amount of $2,500,001 – $3,000,000: 18 months

Cash in the bank isn't the only way to meet reserve requirements. At Rocket Mortgage, the full value of your retirement accounts may count, and in some cases, business and gift funds do too.

Manual underwriting

Jumbo loans are frequently manually underwritten, meaning a human underwriter, rather than an automated system, reviews your tax returns, bank statements, and financial profile.

Manual underwriting can take longer than an automated review, but it gives underwriters room to weigh compensating factors, like strong reserves or a low DTI, if one part of your application is less than perfect.

Jumbo loan rates and costs

The interest rate and fees you’ll pay to get a jumbo loan vary by lender and each applicant’s financial situation.

What affects jumbo loan rates?

Your jumbo loan rate depends on many of the same factors as a conforming loan rate:

• Down payment
• Loan term
• Your credit score
• Current market conditions
• The specific lender and loan program

Jumbo loans historically carry higher interest rates than conforming loans, but that spread has narrowed. For well-qualified borrowers, jumbo rates often are competitive with or even lower than those for conforming loans.

Compare current jumbo loan rates to see how today's rates stack up against conforming loan rates.

Closing costs

You can expect closing costs to total 3% – 6% of your loan amount. However, jumbo loans are larger, and your closing costs will typically be higher in dollar terms than they would be for a conforming loan. For example, on a $900,000 mortgage, closing costs could range between $27,000 and $54,000.

APR, points, and monthly payment

When you compare jumbo loan offers, look beyond the interest rate. Your annual percentage rate (APR) reflects the interest rate plus points, lender fees, and other charges, so it's a more complete measure of what the loan costs you.

Mortgage points, also called discount points, let you pay money up front in exchange for a lower interest rate. Whether points are worth paying depends on how long you plan to keep the loan.

Jumbo loan pros and cons

Now that you know which loan type might fit your situation, you can weigh the advantages and drawbacks of a jumbo loan.

Pros of a jumbo loan

• You can finance a higher-priced home with one mortgage instead of a first mortgage plus a “piggyback” or second mortgage.
• Well-qualified borrowers can often pay competitive interest rates, since jumbo rates aren't always higher than conforming rates.
• You can choose a fixed-rate mortgage or an ARM, and a loan term of 15 or 30 years.
• PMI is not required, but your lender may require you to pay it if your down payment is less than 20% of the purchase price.

Cons of a jumbo loan

• You’ll need a higher credit score and a lower DTI than most conforming loans.
• You’ll need a down payment of at least 10% and maybe as much as 25% – 30%.
• Significant cash reserves may be required.
• Many jumbo loans undergo manual underwriting, which can take more time and paperwork.
• You’ll pay higher closing costs in dollar terms, since costs usually are a percentage of your loan amount.

Can you refinance a jumbo loan?

You can refinance a jumbo loan to secure a lower rate, change your loan term, or tap your home equity with a cash-out refinance.² You'll go through underwriting again and need to meet your new lender's credit, income, and cash reserve requirements.

Compare current jumbo loan refinance rates before deciding whether refinancing makes sense for you.

FAQ

Here are answers to common questions about jumbo loans.

Do you have to put 20% down on a jumbo loan?

No. Many lenders, including Rocket Mortgage, allow a down payment as low as 10%, though your minimum will depend on your credit profile, loan amount, and property type.

What is the downside of a jumbo loan?

The main downsides are stricter underwriting, larger cash reserve requirements, a bigger down payment, and, in some cases, higher borrowing costs than a comparable conforming loan. Approval can also take longer, since jumbo loans are frequently manually underwritten.

Is a jumbo loan more difficult to get?

Generally, yes. Because jumbo loans are larger and aren't backed by a government agency, lenders take on more risk. That typically means you need a higher credit score, lower DTI, and larger cash reserves than you'd need for a standard conforming loan.

Why would someone get a jumbo loan?

Borrowers use jumbo loans when they need to finance a home priced above their county's conforming loan limit. A jumbo loan lets you buy that home with a single mortgage, rather than splitting the purchase across a first mortgage and a second, or piggyback, loan.
