Jumbo Loans: Requirements and Best Rates

Every year the Federal Housing Finance Agency (FHFA) sets the conforming loan limit — the maximum loan size that Fannie Mae and Freddie Mac will buy from lenders. For 2026, the baseline conforming limit for a single-family home in most of the US is $832,750, up 3.26% from the 2025 limit of $806,500.

In high-cost areas — think coastal California, New York metro, Hawaii, parts of Colorado — the ceiling is higher. High-cost area limits go up to $1,249,125 for a single-family home in 2026. Alaska, Hawaii, Guam, and the US Virgin Islands have their own limits reaching $1,873,675.

Any mortgage above your area's conforming limit is a jumbo loan. Jumbo loans can't be bought by Fannie or Freddie, so lenders either hold them in their own portfolio or securitize them privately. Because they can't offload the risk, lenders apply stricter standards and typically charge higher rates.

If you're buying in a major metro and shopping in the $900k-$2M range, you're almost certainly in jumbo territory. Understanding the requirements upfront saves you from the frustration of getting pre-approved by a standard lender only to find out you don't qualify once the loan officer runs your full profile.

For conventional conforming loans, lenders will work with 620. For jumbo loans, the floor is typically 700, and that's barely the floor — most lenders want 720+ to approve you, and the truly competitive rates go to borrowers at 740 and above.

Why the difference? Conforming loans get sold to Fannie or Freddie, who've priced the risk of lower credit scores into their guarantee structure. Jumbo loans stay on the lender's balance sheet or get sold to private investors. Those investors demand higher credit quality.

There's also a loan size effect: when the loan is $1.2 million, a default is a much bigger problem than a default on a $250,000 loan. Lenders price that asymmetry into their requirements.

If your score is in the 680-700 range and you need a jumbo loan, your options are narrow. A few specialty lenders will go down to 680, but at a significant rate premium. Better strategy: spend 6-12 months improving your score before applying. The rate savings on a $1M loan from going from 690 to 740 can be worth tens of thousands of dollars over the loan life.

Debt-to-income ratio (DTI) — your monthly debt payments divided by your gross monthly income — is more tightly managed on jumbo loans than on conforming loans.

For conventional conforming loans, you can often get approved up to 50% DTI with strong compensating factors. For jumbo loans, most lenders want to see DTI at or below 43%. Plenty of lenders will cap you at 38-40% for large loan amounts.

Self-employed borrowers face additional scrutiny. Conforming lenders can use Fannie's automated underwriting systems which have some flexibility for self-employed income. Jumbo lenders doing manual underwriting look at two years of tax returns, and if your Schedule C shows significant write-offs that reduce taxable income — as it should — that's the income figure they use. Your gross revenue doesn't matter. What you reported to the IRS does.

Bank statement loans — where you qualify based on 12-24 months of bank deposits rather than tax returns — exist in the jumbo space but cost significantly more in rate. Expect 0.5-1.5% higher than a fully documented jumbo loan.

The income documentation pile for a jumbo loan is substantial: W2s for the past 2 years, federal tax returns for the past 2 years, 30 days of recent pay stubs, 2-3 months of bank statements, investment account statements, and documentation of any other income sources. Get this stack ready before you start the process.

Conforming conventional loans can go as low as 3-5% down. Jumbo loans: forget it. The minimum down payment for a jumbo loan is typically 10-20%, and many lenders require 20% for loan amounts over $1.5 million.

The 20% figure isn't arbitrary — it eliminates the need for private mortgage insurance (jumbo loans don't use conventional PMI programs anyway, but the principle of equity buffer applies) and significantly reduces the lender's loss-given-default risk.

Some lenders offer 10% down jumbo loans but reserve these for borrowers with exceptional credit scores (760+), strong income, and significant reserve requirements. At 10% down on a $1.2M property, you're asking a lender to take on $1.08M of credit risk. They're going to want to be very confident you can pay.

Loan-to-value ratios also affect your interest rate. Lower LTV (more equity) = better rate. A 20% down jumbo loan will price better than a 10% down jumbo loan even with the same credit score and income.

This is where jumbo loans get serious — and where many buyers who can technically make the purchase are surprised.

Conforming lenders typically want to see 2 months of PITI (principal, interest, taxes, insurance) in reserves after closing. Jumbo lenders want 6-12 months. For some large jumbo loans ($2M+), reserve requirements of 12-24 months are common.

On a $1.5M jumbo loan with a $10,000/month PITI payment, 12 months of reserves means $120,000 in liquid or semi-liquid assets after your down payment and closing costs. Not in your 401(k). Not in home equity. Liquid.

This catches buyers off guard. You've saved for your down payment, you have enough for closing costs, and then the underwriter tells you they need to see $100,000+ in additional reserves. Plan for this well in advance.

What counts as reserves: checking and savings accounts, money market accounts, stocks and bonds (usually at 70% of current value for volatile assets), and retirement accounts (usually at 60-70% of value). Real estate equity, unvested stock options, and HSAs typically do not count.

Historically, jumbo loans carried a rate premium of 0.25-0.5% above conforming loans, reflecting the additional risk lenders take on. In 2026, the relationship is more nuanced.

Current jumbo rates (March 2026) run approximately 6.75-7.25% for a 30-year fixed with strong borrower profiles, compared to 6.5-7.0% for conforming conventional loans. That's roughly a 0.25% premium — on the low end of historical norms.

Interestingly, for borrowers near the conforming limit, a slightly larger down payment that keeps the loan below the conforming limit can be worth it. On a $900,000 purchase in a standard-cost area: a $70,000 down payment leaves an $830,000 loan — just under the $832,750 conforming limit — and qualifies for better rates and relaxed requirements. A $60,000 down payment creates an $840,000 jumbo loan. That $10,000 difference in down payment could be worth thousands per year in interest savings.

Adjustable-rate mortgages (ARMs) tend to be more common in the jumbo space because buyers with large loan balances are often financially sophisticated and comfortable with rate risk. A 7/1 ARM or 10/1 ARM on a jumbo loan typically offers a 0.5-1.0% rate discount versus the 30-year fixed, which on a $1.5M loan is $7,500-$15,000 per year in interest savings. If you plan to sell or refinance within 7-10 years, the ARM math often wins.

Not all lenders do jumbo loans well. Here are the ones worth calling.

Chase has one of the best jumbo programs at major banks. Relationship pricing for existing Chase customers can reduce rates meaningfully — if you have significant assets at Chase, ask specifically about jumbo pricing before shopping anywhere else. Chase also has strong jumbo underwriting capability across the country.

Wells Fargo's jumbo program is solid for high-balance loans, and their portfolio lending ability means they have more flexibility on non-standard situations than conforming-only lenders. Same caveats about the bank's broader regulatory history apply.

Citizens Bank consistently shows up as a competitive jumbo lender, particularly in the Northeast where their branch network is strongest. Worth including in any East Coast comparison.

First Republic — now part of JPMorgan after the 2023 collapse — was legendary for ultra-low jumbo rates tied to banking relationships. That program has evolved under JPMorgan but the philosophy of relationship pricing for wealthy clients continues.

Navy Federal Credit Union offers jumbo loans for eligible military borrowers at consistently competitive rates. If you qualify for membership, it should be your first call.

Private banks and wealth management arms: if you have $1M+ in investable assets, private banks (Morgan Stanley, Goldman Sachs, UBS, Citi Private Bank) offer portfolio mortgages with extremely competitive rates tied to the banking relationship. These loans don't always make it into public rate comparisons. They're worth a conversation if you have a wealth management relationship.

For complex situations — unusual income, business owners, large loan amounts above $3M — mortgage brokers with jumbo specialty experience often find programs that retail lenders won't touch. Find a broker who specifically advertises jumbo expertise, not a general broker who happens to do some jumbo loans.

Allow more time. Jumbo loans take longer than conforming loans because manual underwriting is the norm, more documentation is required, and appraisals for high-value properties are more complex — and sometimes require two appraisals on properties over $1M or $1.5M (lender-dependent).

Plan for 45-60 days from application to close for a standard jumbo transaction. In competitive markets, get a pre-approval letter before you start seriously shopping — a real pre-approval where a human underwriter has reviewed your income and assets, not just a pre-qualification based on stated information.

Appraisals for high-value properties are trickier. Comparable sales data is sparse in some price ranges, and appraisers have more discretion. Appraisals coming in low on jumbo properties isn't uncommon. Know before you make an offer whether comparable sales support the price — your real estate agent should pull comp data regardless, but it matters more on a jumbo transaction.
