Most home loans are “conforming,” meaning they fall under the maximum amount that Fannie Mae and Freddie Mac can buy. When the amount you need to borrow is above the conforming limit for your county, you need a jumbo loan. Jumbo loans are not government-insured and cannot be sold to the housing finance agencies, so each lender or investor sets its own guidelines. That tends to mean stricter standards but also more customization. Bethany Sanchez (NMLS #2425491) helps Scottsdale-area buyers and owners understand jumbo financing and decide whether it is the best route.
Quick answer: A jumbo loan finances an amount above the conforming limit. Expect stronger credit, larger down payments, more cash reserves and fuller documentation than a typical conforming loan. This is educational and not a commitment to lend.
Conforming vs. jumbo vs. high-balance
Understanding the categories helps you plan:
- Conforming loans are at or under the baseline limit that applies to most counties.
- High-balance conforming loans exceed the baseline but remain under the higher limit set for designated high-cost counties. They still follow Fannie Mae and Freddie Mac rules and often have terms similar to standard conforming loans.
- Jumbo loans exceed the local conforming limit entirely.
Check your county’s limit before you assume you need a jumbo loan. In some high-cost areas, a loan that looks large may still qualify as high-balance conforming, which can be easier and less costly. We check the limits for you.
Who needs a jumbo loan?
- Buyers of higher-priced homes who want to borrow more than the local conforming limit
- Homeowners refinancing a large balance
- Buyers who want to put down a small percentage on a pricey property
- Borrowers purchasing a second home or vacation property with a large loan
- Buyers whose income is strong but variable, such as business owners and executives with equity compensation
Typical jumbo requirements
Requirements differ widely, but these are common features.
| Factor | What lenders often look for |
|---|---|
| Credit score | Strong, often in the upper tier of scores |
| Down payment | Larger than conforming, often 10 to 20 percent or more |
| Debt-to-income ratio | Often lower than conforming limits |
| Cash reserves | Several months to a year or more of payments, depending on the loan |
| Income documentation | Detailed, including tax returns, pay stubs, W-2s and asset statements |
| Appraisal | Full appraisal, sometimes two for larger loans |
| Property type | Primary, second home and sometimes investment properties |
Lenders want to be confident that a larger loan will be repaid, so they scrutinize the full file. Having your documents organized in advance makes a large difference.
Documentation to prepare
A jumbo file is typically more extensive than a standard conforming loan. Prepare:
- Two years of tax returns, including all schedules
- Recent pay stubs and W-2s, or business financial statements for self-employed borrowers
- Two or more months of statements for every account, including retirement and brokerage accounts
- Documentation of any large deposits
- Information on stock compensation or bonuses, if you want them considered
- Documents for other real estate you own
- Gift letters, if applicable
Costs and terms
Jumbo loan costs vary based on lender, loan size, down payment and credit. Compare the interest rate, points, fees and any requirement to hold assets or maintain accounts with the lender. Some jumbo programs allow you to avoid mortgage insurance with a lower down payment, while others require a larger down payment. Terms include fixed-rate loans and adjustable-rate loans, and ARMs are more common in jumbo lending than in smaller loans. We do not publish rates on this website.

Jumbo vs. conventional: which is right?
If you can reduce your loan amount below the conforming limit through a larger down payment, a conforming or high-balance loan may cost less and have simpler guidelines. If you prefer to keep more cash, invest elsewhere or the property price requires a larger loan, jumbo financing can still be the right choice. Whatever you choose, make sure you can handle the payment, taxes and insurance comfortably even if your income or the market changes.
Tips for a smooth jumbo loan
- Start early. Jumbo underwriting takes more documentation and time.
- Keep finances steady. Avoid new debt or large transfers between accounts.
- Know your reserves. Be ready to show how much cash you have after closing.
- Plan for the appraisal. A larger loan may require a more detailed valuation, and unique properties can take longer.
- Compare options. Different lenders have different guidelines and pricing, so compare Loan Estimates.

Frequently asked questions
What makes a loan a jumbo loan?
A loan is jumbo when the amount exceeds the conforming loan limit for the county where the home is located. The Federal Housing Finance Agency sets the limit each year, and it is higher in designated high-cost areas. Because jumbo loans cannot be bought by Fannie Mae or Freddie Mac, lenders set their own rules.
How much down payment do I need for a jumbo loan?
It varies by lender, credit profile and loan size, but jumbo loans commonly require larger down payments than conforming loans, often in the range of 10% to 20% or more. Larger loans and weaker credit profiles typically require more.
What credit score do I need for a jumbo loan?
Jumbo lenders generally want strong credit, often with scores in the high 600s to 700s or above, although requirements vary. A higher score and lower debt ratios can help with approval, pricing and flexibility.
Do jumbo loans require more reserves?
Usually yes. Lenders want to see that you have cash or liquid assets left after closing, commonly several months of payments and sometimes much more for larger loans. The reserve requirement depends on the loan amount, your credit and the property.
Are jumbo loans only for expensive cities?
No. Any loan above the local conforming limit is a jumbo loan, including in areas where homes cost less than the national average but the limit is also lower. Whether you need a jumbo loan depends on the amount you borrow, not just the price of the home.
Can I refinance into a jumbo loan?
Yes. Borrowers refinance jumbo loans to adjust their terms, to move from an adjustable to a fixed rate, or to take cash out within the lender's limits. Standards are generally stricter than for smaller loans, and appraisals may be more detailed.
