A jumbo loan is a mortgage that exceeds the conforming loan limit set by the Federal Housing Finance Agency, which means it can’t be purchased by Fannie Mae or Freddie Mac. For 2026, that threshold is $832,750 for a single-family home in most of the country, and up to $1,249,125 in high-cost areas. If you need to borrow more than that, you’ll need a jumbo loan, and qualifying for one requires stronger finances than a standard mortgage.
When the Conforming Limit Applies
The conforming loan limit determines where conventional financing ends and jumbo territory begins. In most U.S. counties, any mortgage above $832,750 for a one-unit property is a jumbo loan. In high-cost areas where home prices run well above the national median, the ceiling rises to $1,249,125. Alaska, Hawaii, Guam, and the U.S. Virgin Islands have their own statutory provisions, with a baseline of $1,249,125 and a ceiling of $1,873,675.
These limits adjust annually based on home-price changes. If you’re buying near the boundary, it’s worth checking whether your county qualifies as a high-cost area, since staying under the conforming limit gives you access to more lenders and typically simpler underwriting.
Down Payment Requirements
Lenders typically require 10% to 20% down on a jumbo loan, with some allowing as little as 10% for well-qualified borrowers. That’s a meaningfully larger upfront commitment than the 3% to 5% minimums common on conforming loans. On a $1 million purchase, expect to bring at least $100,000 to $200,000 to the table.
Putting down less than 20% usually means paying private mortgage insurance, just as with conventional loans. But because the loan balance is larger, that monthly PMI cost will be higher too. Many borrowers aim for 20% down specifically to avoid it.
Credit Score and Debt-to-Income Ratio
Most jumbo lenders look for a credit score of at least 700, and many prefer 720 or higher. The stronger your score, the better your interest rate and the more flexibility you’ll have on other requirements like down payment size.
Your debt-to-income ratio (the percentage of your gross monthly income that goes toward debt payments) matters more on a jumbo loan than on a conforming one. Lenders generally want to see a DTI of 43% or lower, though some set the bar at 36%. To calculate yours, add up all monthly debt obligations: the projected mortgage payment, car loans, student loans, minimum credit card payments, and any other recurring debt. Divide that total by your gross monthly income. If your DTI is borderline, paying down existing debt before applying can make a real difference.
Cash Reserves You’ll Need
One of the biggest differences between jumbo and conforming loans is the cash reserve requirement. Lenders want proof that you can continue making mortgage payments even if your income gets interrupted. Expect to show between 6 and 30 months’ worth of expenses sitting in liquid accounts like savings, checking, or investment accounts. The exact number depends on the loan amount: a $900,000 mortgage will have a lower reserve threshold than a $2 million one.
Reserves don’t have to be cash in a savings account. Most lenders count stocks, bonds, mutual funds, and retirement account balances (often at a discounted value, since early withdrawal involves penalties). What they won’t count is money you can’t access quickly, like equity in other real estate or the value of personal property.
Documentation and Underwriting
Jumbo loans are often manually underwritten, meaning a human reviews your entire financial picture rather than running it through an automated system. This makes the process more thorough and sometimes slower than a conforming loan.
You’ll need to provide extensive documentation of your income, assets, and employment. For W-2 earners, that typically means two years of tax returns, recent pay stubs, and W-2 forms. Self-employed borrowers face even more scrutiny: expect to provide two years of business tax returns, profit-and-loss statements, and possibly a letter from your CPA. Lenders may also ask for additional proof that your income is stable and unlikely to change after closing.
Some lenders require two home appraisals instead of one, particularly on higher loan amounts. This adds a few hundred dollars to your closing costs and can extend your timeline by a week or two, but it protects both you and the lender from overpaying.
How Jumbo Interest Rates Compare
Jumbo loans have historically carried slightly higher interest rates than conforming loans because lenders can’t offload the risk to Fannie Mae or Freddie Mac. They hold these loans on their own books, which means they price in that added exposure.
That said, the gap has narrowed considerably in recent years, and jumbo rates sometimes dip below conforming rates. Lenders compete aggressively for high-balance borrowers who tend to have strong credit profiles and significant assets. Your specific rate will depend on your credit score, down payment, DTI, the loan amount, and the lender you choose. Shopping at least three or four lenders is especially important with jumbo loans because pricing varies more widely than it does in the conforming market.
Steps to Get a Jumbo Loan
Start by reviewing your finances against the requirements above. Check your credit score through your bank or a free monitoring service, calculate your DTI, and tally your liquid reserves. If any of those areas are weak, spend a few months strengthening them before you apply. Paying down a car loan or credit card balance can improve both your DTI and your credit score simultaneously.
Get preapproved with at least two or three lenders. Preapproval involves a full credit pull and document review, so you’ll know your actual borrowing power rather than an estimate. Because jumbo underwriting is manual, turnaround on preapproval can take a bit longer than you’re used to.
Once you’re under contract on a home, your lender will order the appraisal (or appraisals), verify your employment, and finalize your documents. The closing timeline for a jumbo loan is often 45 to 60 days, compared to 30 to 45 for a conforming loan. Build that extra time into your purchase agreement so you’re not scrambling at the deadline.
Choosing a Lender
Not every lender offers jumbo loans, and among those that do, the terms vary significantly. Large national banks, credit unions, and online lenders all compete in this space, but their rate sheets, reserve requirements, and down payment minimums can differ by meaningful amounts.
Pay attention to more than just the interest rate. Compare the annual percentage rate, which includes origination fees and other costs rolled into the loan. Ask each lender about their specific reserve and DTI requirements, since these aren’t standardized the way conforming loan guidelines are. A lender that requires only 6 months of reserves versus one that requires 18 months could make the difference between qualifying and not.
