Jumbo loan cash reserves requirements can be a challenge for homebuyers. Some lenders require 12 months' worth of mortgage payments in reserves, while others may accept as little as 2-3 months.
Having sufficient cash reserves can be a significant burden, especially for those with limited savings. However, it's a crucial factor in securing a jumbo loan.
To qualify for a jumbo loan, borrowers typically need to have a debt-to-income ratio of 43% or less. This means their monthly debt payments should not exceed 43% of their gross income.
A good credit score is also essential for jumbo loan approval, with a minimum score of 720 often required.

What Are Cash Reserves?
Cash reserves are a crucial aspect of jumbo loan requirements. Different lenders have varying requirements for cash reserves, which can be a challenge for borrowers.
Lenders consider all recurring housing expenses for the subject property when determining cash reserve requirements. This includes principal, interest, taxes, insurance, and assessments (PITIA).

Housing expenses can be broken down into several categories, including:
- Principal and Interest (as used in the qualifying payment amount)
- Insurances (hazard, flood, and/or mortgage)
- Real Estate Taxes
- Ground rent/leasehold
- Special Assessments
- Homeowners’ association fees
- Monthly co-op fees
- Any home equity loan or HELOC payment, if applicable
Cash reserves are cumulative, meaning that if you're buying a new home and have a rental property, you may need to meet the requirements for both properties.
Jumbo Loan Requirements
Jumbo Loan Requirements are stricter than conforming loans, so it's essential to meet the lenders' criteria to qualify. A minimum credit score of at least 680 is typically needed to qualify for a jumbo loan.
To boost your odds of getting approved, you'll also need a low debt-to-income ratio and cash reserves to cover six to 12 months of mortgage payments. This can include savings accounts, checking accounts, investment accounts, retirement accounts, and other liquid assets.
A sizable down payment is also required, with many lenders requiring at least 20% of the home's purchase price. For example, on a $1 million home, this would be a $200,000 down payment.

Retirement Accounts as Cash Reserves
Retirement accounts can now be used as cash reserves for jumbo loans, a significant development that can make it easier to qualify for a jumbo mortgage.
Lenders are considering the balance of retirement accounts, such as 401(k), 403(b), IRA, and TSP, without requiring you to liquidate or borrow against the account.
This means you don't have to deplete your retirement savings to meet the cash reserves requirement, which can be a huge relief.
Having a strong savings plan and a savings account with tools to help you save more can still be helpful in building up your down payment and covering closing costs.
Retirement accounts are not considered very liquid, which is why some lenders have previously not allowed them to count towards cash reserves requirements.
Currently, many lenders allow retirement accounts to be used as cash reserves, making it a more viable option for borrowers.
Loan Requirements
To qualify for a jumbo loan, you'll need a minimum credit score of at least 680. This is a stricter requirement than conforming loans.

A low debt-to-income ratio is also crucial, as lenders want to ensure you can afford the loan payments. Typically, a DTI ratio as high as 49.9% may be allowed, but this can come with restrictions and a higher interest rate.
You'll also need to show cash reserves to cover six to 12 months of mortgage payments. This includes principal, interest, taxes, insurance, and assessments (PITIA).
Some examples of cash reserves include savings accounts, checking accounts, investment accounts, retirement accounts, and other liquid assets.
Here are the key loan requirements to keep in mind:
- Minimum credit score: 680
- Low debt-to-income ratio
- Cash reserves to cover 6-12 months of mortgage payments
- Sizable down payment (typically 20% or more)
- Higher closing costs
- Appraisal required
- Manual underwriting

Understanding Jumbo Loans
Jumbo loans are typically defined as mortgages that exceed the conventional loan limit, which is $510,400 in most areas.
These loans require a larger down payment, often 20-30% of the purchase price.
Jumbo loans have stricter credit score requirements, typically 700 or higher.
Borrowers may need to provide additional documentation, such as proof of income and assets.
A higher debt-to-income ratio can make it more difficult to qualify for a jumbo loan.
Lenders may also consider the borrower's credit history and employment stability.
Emergency Funds
Having a solid emergency fund is crucial when applying for a jumbo loan. You'll want to show that you have enough cash reserves to cover several months of mortgage payments.
The exact amount required for cash reserves varies by lender, but it's reasonable to expect that jumbo lenders will want to see proof of six to 24 months of cash in your bank account.

You'll need to calculate the number of monthly mortgage payments you'd be able to cover with your savings. This will give you a clear picture of your cash reserves.
Jumbo lenders may also consider your credit score, DTI ratio, the type of property you're financing, and how many homes you have financed when determining your required cash reserves.
Loan Comparison
Loan comparison is crucial when considering a jumbo loan with cash reserves.
To start, you'll want to compare interest rates, which can vary significantly between lenders. For example, in one scenario, a lender offered a 30-year fixed rate of 4.25%, while another lender offered a rate of 4.5%.
Considering the total cost of the loan is also essential. This includes not only the interest rate but also fees associated with the loan. A lender may charge a higher interest rate but lower fees, making it essential to compare these costs as well.

What Constitutes a Loan?

A jumbo loan is any conventional mortgage larger than the conforming loan limits set by the Federal Housing Finance Agency (FHFA) each year. In 2025, single-family mortgages with balances higher than $806,500 are considered jumbo loans.
Conforming loan limits vary by county, so your loan limit is determined by the county in which you intend to purchase the property.
Loans vs. Conforming
Jumbo loans are a type of mortgage that differs significantly from standard mortgages, also known as conforming loans. This is because jumbo loans have no maximum loan limit, whereas conforming loans are capped at $510,400.
Conforming loans, on the other hand, are mortgages that meet the guidelines set by Fannie Mae and Freddie Mac, and are typically considered standard mortgages. Jumbo loans, however, are for borrowers who need to purchase a more expensive home, often requiring a larger down payment and stricter credit requirements.
The main difference between jumbo and conforming loans is the loan amount, with jumbo loans exceeding the conforming loan limit. This difference can impact the interest rate and fees associated with the loan.
