The Quick Read: A loan is jumbo when the amount you borrow is above the conforming limit for the county where the home sits. The price of the home does not decide it. Most counties share one baseline limit, a minority get a higher limit, and the loan amounts in between are the “high-balance middle.” Check the Federal Housing Finance Agency (FHFA) county list for the current year before you shop.
Key Takeaways
- The loan amount decides it. Price minus your down payment is compared to the county limit.
- One national baseline covers most counties. FHFA’s FAQ says over 95% of counties sit at it.
- A smaller group of counties gets more. The limit there is 115% of the local median home value, capped at 150% of the baseline.
- The middle is a band, not a label. It runs from the baseline up to the county’s own ceiling, and its width differs by county.
- Limits are lookups, not guesses. They reset each year, so use the official list.
What Makes a Loan Jumbo?
A loan is jumbo when it is above the conforming limit that applies to the home. FHFA sets it, and FHFA’s conforming loan limit announcement explains the baseline and the high-cost test.
Jumbo payment estimate
The starting figures are an example price in the jumbo range with ten percent down on a thirty-year fixed. Replace them with yours.
Editable benchmark: 7.40% as of October 15, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a jumbo loan quote.
Illustrative starting assumptions: a $1,000,000 price in the jumbo range, ten percent down on the top-leverage lane, a thirty-year fixed structure at the current Freddie Mac conforming benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conforming benchmark, a market reference and not a jumbo loan quote; jumbo rates are set by the lender and the lane at lock and differ from the conforming benchmark. An adjustable-rate scenario is shown at the benchmark for the whole term; the rate after the initial period is unknown. Reserve months and appraisal counts follow the lane sheet for the amount band; the automated finding may require more. Taxes, insurance and dues are editable estimates; closing costs are not included. On most lanes the conforming limit for the county decides whether a loan is jumbo at all; two lanes start at a stated dollar floor instead. Licensed in sixteen states for consumer mortgages.
Above the limit, the agencies can’t buy the loan. The lender keeps it or sells it to private investors, who set their own rules. In practice, a jumbo loan begins one dollar over the county limit.
Jumbo does not mean weak credit or a risky borrower. A loan can be non-conforming only because of its size. A buyer with strong credit and a large balance is the typical jumbo borrower.

How Is the County Limit Set?
The county limit starts with a national baseline and rises only where local home values justify it. Each year FHFA moves the baseline by the change in its House Price Index. The most recent move was about 3.26%, per FHFA’s addendum. Then FHFA tests each area for a high-cost limit.
Here is the process, step by step:
1. Start with the baseline. This is the one-unit limit for most of the country.
2. Find the local median home value. FHFA uses federal median value estimates, matched to the county.
3. Multiply that median by 115%.
4. Compare the result to the baseline. If it is lower, the county stays at the baseline. If it is higher, the county limit rises to that figure.
5. Apply the ceiling. By statute the limit can’t exceed 150% of the baseline for a one-unit home.
Two quick ratios help you see where a county lands:
- A county leaves the baseline once its median home value reaches the level where 115% of that median catches up to the baseline limit.
- A county hits the ceiling once its median reaches the level where 115% of that median equals the ceiling limit.
Everything between those two points is the high-balance middle. The limit there is 115% of the median, so it moves up smoothly with local prices.
FHFA’s own worked example is Santa Barbara County, California. Its median value times 115% landed above the baseline and below the ceiling, so that product became the limit. The Washington, DC metro area is the opposite case. 115% of its median was above the ceiling, so the ceiling applied. Both examples come from FHFA’s FAQ.
The Three Tiers at a Glance
Most buyers sit in one of three tiers. The table shows what shifts for you at each.
| Tier | Where it applies | Who sets the rules | What changes for you |
|---|---|---|---|
| Baseline (conforming) | Most counties, over 95% | Agency rules | Loan at or under the baseline |
| High-balance middle | Counties with higher medians | Often the same agency rules | Loan above the baseline, under the county limit |
| Jumbo | Any loan over the county limit | Lender or investor | Guidelines vary by lender |
The middle tier is a loan-size band that exists only in some counties. Lenders often call it “high-balance,” but that is an industry label, not a federal term. Whether a given lender treats a middle-band loan under agency-style rules or as a jumbo loan depends on the lender.
Where the High-Balance Middle Sits
The middle sits in counties where home values are well above average but short of the very top. Think of mid-priced suburbs of expensive metros and mid-sized coastal markets, rather than the priciest few counties. There is no tidy list, because the middle depends on one calculation per county.
Three patterns explain most of it:
- Baseline counties have no middle. Over 95% of counties sit at the baseline, so for most buyers the choice is conforming or jumbo, with nothing between.
- Ceiling counties have a full band. There the whole span from the baseline to the ceiling is a high-limit zone, and jumbo starts only above it.
- Intermediate counties have a partial band. Their limit lands somewhere between the two, so the band is narrower.
You can measure the band for your county: take the county limit and subtract the baseline. The widest possible band is half the baseline, since the ceiling is 150% of it. A county only slightly above the baseline has a thin band. A county at the ceiling has the widest.
Why Your Neighbors Can Matter
FHFA looks at the whole metropolitan or micropolitan area, not only your county. It compares the counties inside the area and uses the highest county median for all of them. A lower-priced county can therefore carry the higher limit of its pricier neighbor. This is why two homes a few miles apart can fall in different tiers, and why a county line matters more than your address in a pricey metro.
The limit is set by county or metro area, not by state. Two counties in the same state can sit at very different limits.
Limits Rarely Drop
FHFA does not let any limit fall below earlier values. Each year’s figure is the higher of the new calculation and the values from prior years. If local prices dip, your county’s limit generally holds. The baseline was frozen for about ten years before it started rising, a reminder that limits are sticky in both directions. Limits rose almost everywhere in the latest round, but FHFA reported 32 counties or county equivalents where they did not, per Orrick’s summary.
Same Loan, Different County
Compare the loan to the limit, not the home price to a number. Three short scenarios show how that works, described in percentages.
Scenario one: down payment moves the tier. A buyer purchases a home priced about 20% above the county limit. With 25% down, the loan is 75% of the price, which lands under the limit and stays conforming. With 10% down, the loan is 90% of the price, which is above the limit and makes it jumbo. The price did not change, only the loan. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Scenario two: the same loan in two counties. Two buyers each borrow the same amount. One is in a baseline county and the other is in a county with a high-cost limit. The first loan is jumbo and the second is a high-balance loan. The numbers match, but the county changes the category.
Scenario three: a middle-band loan with a choice. A buyer in a ceiling county borrows more than the baseline but less than the county limit. That loan fits the high-balance band. Some buyers still look at a jumbo structure, because a jumbo lender may offer features the agency route does not, such as different reserve rules or a different limit on the loan size. The choice is a comparison of what each route asks of the file and what it offers, and it depends on the lender.
What a Jumbo File Looks Like
Across the wholesale programs Lendmire places files with, the headline jumbo lane starts with a 660 decision score. That is a floor, not a promise, and stronger credit helps a file at larger amounts. Leverage reaches up to 90% on the headline lane. Several lanes allow up to 89.99% combined loan-to-value, and the rest stop at 80%. Loan amounts reach $5,000,000 on the largest lanes.
On the fixed-rate lanes, the debt-to-income ceiling is 50%. It is 45% on adjustable lanes and 43% on interest-only lanes. Fixed, adjustable and interest-only structures all exist, and some lanes accept non-warrantable condominiums.
Other parts of the file scale with the loan amount. Reserves are counted in months of the full payment, and the month count rises as the amount grows. Above a lane’s threshold amount, two appraisals are required. Occupancy matters too: primary residence, second home and investment occupancy each carry their own leverage, and a purchase gets higher leverage than a cash-out refinance. The largest lanes also put a cash cap on cash-out loans.
Every figure here is subject to lender guidelines and a full file review, and none of it is a commitment to lend. Consumer jumbo loans also carry a Loan Estimate and a Closing Disclosure like any other home loan.
Do Jumbo Loans Skip Federal Rules?
No. Jumbo loans still fall under the federal ability-to-repay rule. The lender has to consider and verify income or assets, debts and housing costs. The CFPB’s General QM rule replaced the old fixed ratio cap with price-based thresholds. The Congressional Research Service notes that a first-lien loan gets safe-harbor status when its APR sits within 1.5 percentage points of the average prime offer rate.
A loan can still be made outside those lines if the lender documents the borrower’s ability to repay. Some small banks hold loans in portfolio under their own qualified mortgage rules, which carry no fixed ratio cap. These details sit on the lender’s side. For you, the practical effect is documentation: expect to show income, assets and reserves clearly.
Middle Tier or Jumbo: How to Decide
Work through these questions in order.
1. What is my county’s limit for my unit count? Look it up on the FHFA list.
2. What is my loan amount? Use the price minus a realistic down payment.
3. Am I under the baseline? If so, a standard conforming loan is the first thing to compare.
4. Am I in the band between baseline and county limit? Ask the lender whether it prices this as high-balance or jumbo, and compare both routes if offered.
5. Am I over the county limit? Then you are jumbo. Compare lanes by leverage, reserves, appraisal needs and ratio ceiling.
6. Can a larger down payment move me down a tier? Sometimes it can. Weigh that against keeping cash in reserve.
Limits apply to the new loan amount, so a refinance can land in a different tier than your original loan.
Where the General Rule Breaks
A few cases don’t follow the simple one-unit pattern.
- Multi-unit homes. Two-, three- and four-unit properties get higher limits, built by applying unit multipliers to the same local figure. If you live in one unit of a duplex, the two-unit limit applies. Use the FHFA county list for these figures, because trade summaries sometimes disagree.
- Alaska, Hawaii, Guam and the U.S. Virgin Islands. These areas start from a higher statutory baseline, so their limits sit higher.
- Metro spillover. A county can inherit a higher limit from a pricier neighbor in the same area.
- Year boundaries. The limit in force depends on the effective date, which is January 1. A loan near a year-end can be treated differently, so ask your lender early how it handles timing.
- FHA. FHA county limits are tied by statute to the conforming limits, with a lower floor and the same ceiling. That is a separate program with its own rules, so check it on its own terms.
How to Check Your County
Go to the FHFA announcement page for the current year and open the county list or map. Find your county, or your metro area if the county is not listed on its own, and read the limit for your unit count. Note the year printed on the list. Some web pages mix prior-year and current-year figures, so use the official FHFA source instead of a summary.
Then compare that limit to your planned loan amount. If you are within a few percent of the line, run both scenarios, one with a slightly larger down payment and one without.

Ability to repay: The federal rule that lenders must reasonably confirm you can afford the loan.
Frequently Asked Questions
Is a jumbo loan based on the home’s price or the loan amount?
The loan amount. A home can cost more than the county limit and still carry a conforming loan if your down payment brings the balance under it. One dollar over the limit makes the loan jumbo.
Does every high-cost state get the highest limit?
No. Only areas where 115% of the local median value reaches the ceiling get it. Many counties land in the middle, and most of the country stays at the baseline. Limits follow counties and metro areas, not state lines.
Will my county’s limit drop if home prices fall?
Rarely, if ever. FHFA does not let a limit fall below earlier values, so a dip in prices tends to leave it where it was. A rising limit can also pull a borrower’s loan back under the conforming line.
Can I choose a jumbo loan even if my loan fits the middle band?
Sometimes. Whether a middle-band loan is priced as high-balance or jumbo depends on the lender, and the right route depends on the file. A broker can compare both, subject to lender guidelines and full file review.
Where do I find the limit for a multi-unit home?
On the FHFA county list, which shows limits by unit count. Multi-unit limits are higher than one-unit limits, and trade summaries don’t always match, so use the official list.
